Lincoln County Libraries Distribute Free Science Activity Bags to Kids

Six public libraries in Lincoln County are distributing more than 800 free bags of science activities for kids, thanks to a grant that the Oregon Coast STEM Hub received from the Georgia-Pacific Foundation. Over the past few weeks, STEM Hub staff have been stuffing the bags with supplies and activity instructions and delivering them to libraries. Depending on the intended age group, each bag includes items such as: a magnifying glass, colored pencils, plastic specimen box, pen, journal, lanyard, rubber ball, tape measure, tweezers, eye dropper and a paper microscope called a Foldscope. The supplies support seven daily challenges that help kids to think critically and to observe, deconstruct, create, and draw. The instructions for seven Daily Challenges are provided in both English and Spanish. For more information, visit the new STEM in Libraries webpage.

Family STEM: Tracking Animal Behaviors

By Lindsay Carroll, Oregon Sea Grant

Do you have a cat or dog at home that you find yourself watching a little more closely these days? Have you caught on to some of the behaviors of your pets or perhaps of birds, rabbits, or chipmunks you’ve seen out your window? You may have been inspired to take a closer look at the environment around you after reading the recently published Family STEM blog “Take a Fresh Look at Nature“.

With more time spent at home, you may find that your dog sleeps or rests all day long. You may have also noticed they wag their tail with excitement during play or when you come home from the grocery store. Or possibly those famous looks of guilt when they have gotten into the trash for the 100th time? Either way, all of these actions are behaviors. Do you think you would have noticed the amount of time your dog spends doing these behaviors if you weren’t home with them all of the time?


Over time, scientists have tracked behaviors of a lot of different animals because recording what they are doing (behavior) and how long they are doing it (time) is how we learn more about them. Scientists who study animal behaviors are known as ethologists and they use ethograms as a way to collect data and answer important questions.

When you think of tracking animal behavior, you may think of the famous ethologist, Dr. Jane Goodall, and her work with chimpanzees. It is because of her many years of research and time spent with chimpanzees in their natural environment that we know so much about them. Get inspired by her decades of research!

Then, see first hand the type of behaviors she may have witnessed over the years as you watch the monkeys in this video. Take a mental note or make a list of the various behaviors you observe. 

Have a fish tank at home? Take five minutes to note the different behaviors you observe of your fish. No fish tank? It’s ok, watch the first few minutes of these goldfish and take note of the different behaviors you see. What do the fish spend most of their time doing?

You’re starting to look at these animals a little bit differently, right? Now, watch a zookeeper from the John Ball Zoo use an ethogram to learn more about her dog’s behavior in the backyard. Be sure to take note of the question she is trying to answer about her dog.


Now that we have spent some time observing a few animals and taking note of some of their behaviors, you may have a few questions.

For example, you may wonder “Do fish in my fish tank spend most of their time swimming?” Or even, better — your observations may have inspired you to test a hypothesis, or educated guess, such as “I think the fish in my fish tank spend most of their time swimming.” What other questions might you have about the animals you observed?

Think back to the zookeeper who conducted an ethogram on her dog. What question was she trying to answer? You may have noted that she recently moved to a new home and she wanted to determine if her dog was adjusting well to a new space. By comparing her dog’s previous behavior to the data she collected, she determined her dog appears comfortable in her new home.

Equipped with all of this new knowledge, think of an animal on which you want to use  an ethogram to learn more about their behaviors. What question do you want to ask?


STEP ONE: Select an Animal
If you have pets at home, great! No pets at home? Consider an animal in your backyard OR watch pre-recorded footage of animals listed below.

Photo credit: Oregon Sea Grant

You could also consider conducting your ethogram using one of the following webcams from local zoos and aquariums. But, note that these animals can be very mobile!

STEP TWO: Make Observations and Develop a Question
Whether you are watching your animal live or on a screen, be sure to take a few minutes to note some of their behaviors ahead of time. That way you can use your observations to inform a question you want to answer about your animal.

STEP THREE: Collect Data
Now it is time to collect behavior data on your animal! For your ethogram, you will record the behavior of your animal every 30 seconds for 10-15 minutes. Since we are collecting data, we need a data table. What should your data table look like? Think about the different variables we are considering – behaviors and time. For some pointers – try reflecting back to the zookeeper’s datasheet shown at the end of her video or possibly get some tips from this educator from the Environmental Learning Center. 

STEP FOUR: Draw Conclusions
You have data! Now, think back to your original question. What are some conclusions you can draw from the data collected? What are some of the behaviors your animal exhibited most frequently?  Why did animals do some behaviors more often than others? If you watched the goldfish in the tank – do they actually spend most of their time swimming?

STEP FIVE: Expand and Elevate Your Learning
Interested in expanding and elevating your ethogram abilities? Consider using this Sea Lion Ethogram Datasheet to conduct an ethogram on a sea lion located in Oregon’s Sea Lion Caves. Use footage from the Sea Lion Cave webcam and see what those often loud, smelly, but fun critters are up to these days. Are there new behaviors you are observing? Are there behaviors missing from the datasheet? Have fun with it!

While it may be fun to watch your pets behaviors or learn more about animals via live webcams, we must take a minute to think about why we are doing it. What does it all mean? What information can be gained using ethograms? Not only can scientists learn more about animal behaviors, but once a baseline of behaviors is established, scientists can use ethograms to determine dramatic changes to an animal’s well-being and what may have caused them.

Tracking the behaviors of animals in zoos and aquaria is especially important, as unusual behaviors can often be a sign of changes to the animal’s health. Ethogram data can track different behaviors related to feeding, reproductive status, mating, seasonal changes, age/sex differences, social group dynamics, and more. Having a deeper understanding of these behaviors of animals in captivity could also  inform protection or management of wild animals.

In essence, ethograms help us detect Patterns, which is one of seven cross-cutting concepts that are prevalent throughout all science disciplines. Patterns occur all throughout the natural world. Think about the patterns you notice among honeycombs, flowers, and zebras. Just like these visual patterns, animals exhibit patterns of behaviors as well. Anomalies that we notice are what bring our attention to change and difference in the animal.

It is also important to note that as you move through the process of collecting data for an ethogram, you are engaging in critical Practices of Science. You are: 

  • Asking questions
  • Planning and carrying out an investigation
  • Analyzing and interpreting data
  • Using math
  • Constructing explanations

Knowledge is power! If you used an ethogram to learn more about your pet, you will be equipped with important baseline information that could be used to determine a change in their health or well-being in the future. 

Your curiosity does not need to end here. Consider increasing your data collection frequency – see if you notice new behaviors or perhaps the most common behavior changes. Think critically about what could be causing the differences. Is there a new question you could ask or hypothesis you could test?

Sample Questions:
“Does my pet….”

  • Spend more time on the floor or on the couch?
  • Sleep more than 6 hours a day?
  • Pee on one, many, or perhaps specific objects?
  • Behave differently when it is raining versus sunny? 
  • Act differently in the morning versus in the evening?

Photo credit: Ruby Schmank – Unsplash

Celebrate your newly gained information by sharing it with a friend! Do they also have a pet at home? Perhaps challenge them to use an ethogram to learn more about their pet and compare common behaviors. Does your dog rest more or less than their dog? Or, challenge them to watch the same webcam or online video and compare notes. Options are endless, so have fun with it. You are well on your way to becoming the next Dr. Jane Goodall!

Family STEM: A Week of Fun Challenges

By Cait Goodwin, Oregon Sea Grant

Are you tired of all of the screen time associated with work and school? Are you looking for simple STEM activities that you can do at home with your family? Check out the daily challenges from STEM Week Oregon. There’s an activity for each day of the week!


STEM Week Oregon is a week-long event that takes place annually in May. This state-wide movement celebrates and engages communities in activities involving science, technology, engineering, and math (STEM). Although this year’s STEM Week was officially celebrated May 9-17, you and your family can participate in daily STEM challenges any time!

This spring has been unusual, to say the least. A lot of us have been stuck indoors and spending a lot of our time looking at screens. That’s one reason why Oregon’s STEM Hubs decided that the theme for this year’s STEM Week would be:

STE(A)M Unplugged: Explore your world, Design your world.

Below are seven daily challenges – one for each day of the week. Each is suitable for the whole family, suggests using materials that you already have at home, and doesn’t require you to be on a computer!

Download all of the challenges in English or in Spanish



Paper Tube Raceway
Design a structure that is either freestanding or attached to a wall. This structure will be your raceway for marbles, a car, or another object of your choice.

Download the Saturday challenge description in English or Spanish


Paper Airplanes and Flight
What is the best way to fold a piece of paper to make a paper airplane fly the highest, the farthest, or the fastest?

For this project, use paper from your recycle bin! If you need more design ideas, consult online resources like Fold N Fly, but then unplug once again to generate more iterations and test your design. Make this challenge meaningful by creating an engaging and real-world context. For example:

“Mary the librarian wants to share a message with a coworker who is shelving books on the other side of the library, 15 feet away. However, they are both practicing social distancing and neither wants to speak loudly and disturb others who are working. Design a paper airplane to help Mary send her message.”

Download the Sunday challenge description in English or Spanish



Each of the daily challenges described above provide opportunities to use different skills and disciplines, just like most real-world activities. Looking back, how did your activity involve science or engineering, the “S” and “E” parts of STEM? Educators have identified eight practices that people use in science and engineering. Did you do any of these things when you were engaged in one of the daily challenges?

Science and Engineering Practices
from the Next Generation Science Standards

  • Asking questions and defining problems
  • Developing and using models
  • Planning and carrying out investigations
  • Analyzing and interpreting data
  • Using math and computational thinking
  • Constructing explanations and designing solutions
  • Engaging in argument from evidence
  • Obtaining, evaluating, and communicating information

Think about how you used math during your challenges. For example, did you count, take measurements, make graphs, or make alterations to scale, proportions, or angles? 

How did you use technology in these unplugged challenges? What tools did you use to make structures, dismantle objects, and research new designs?

Finally, you may have noticed the (A) tucked in to the word STEM in this year’s theme. “A” stands for art, which is another subject that can be found throughout disciplines. Did you draw, build, or use other forms of art in your challenges?


No matter how old you are or whether or not you become (or already are) a STEM professional, everyone can participate in activities involving science, technology, engineering, art, and math! Our daily lives are full of STEM, and there will always be opportunities to use STEM to learn more about our world.

Scientists are always wondering about the world around them and those curiosities are what inspire them to learn more. Here’s what scientists from South Slough Reserve were wondering during the 2020 STEM Week What Are You Wondering Wednesday Challenge.



During the 2020 STEM Week Oregon (May 9-17), thousands of families and educators across the state participated in one or more of these challenges, and their activities populated the online STEM Week map. Some participants (including folks from Tillamook, Newport, Florence, and North Bend) even received prizes when their names were drawn at random.

Gold Beach Students Explore Watershed Issues

By Cait Goodwin, Oregon Sea Grant
with Debra Watson, Riley Creek School and Lindsay Carroll, Oregon Sea Grant

When rain falls on Riley Creek School, where does it end up? Are there pollutants in the watershed that could travel to the ocean? Debra Watson’s 5th grade students wanted to find out.

On a rainy day in December, the students headed outside to collect data that could help answer some of their questions. “It was a day when we were having rain and 60MPH gusts of wind, so we were WET!” recalled Debra. Walking around the schoolyard, students observed that the grounds were generally free of litter. But, what about the dog poop they observed near the school? Would the dog poop have an impact on surrounding areas? This led to a great discussion about what is in rainwater and where it goes. The students were left curious about where the water runoff from their playground went after it disappeared down the storm drain.

Riley Creek School is located just south of the Rogue River in Gold Beach, Oregon, and is named after a small creek that flows into the Pacific Ocean. Its location provides students with ample opportunities to explore the watershed and to make connections between the land and sea.

Debra began planning her watershed unit in November, when she first joined a cohort of other south coast teachers in a year-long MWEEs by the Sea project. “MWEE” stands for Meaningful Watershed Educational Experiences, a framework used by the NOAA Bay Watershed Education and Training (B-WET) program, which funded a professional development series facilitated by Oregon Sea Grant in partnership with South Slough Reserve. To ensure field experiences would be “meaningful” for their students, Debra and the other MWEE teachers created long-term project-based learning units that would take their students on repeated, hands-on trips outside to learn about watersheds, local environmental issues, and stewardship opportunities.

Here are some highlights from Debra’s classroom activities in early 2020.

After their initial stormy field experience, the Riley Creek 5th graders spent the early weeks of January learning more about their watershed through readings, discussions, and videos. To introduce her students to the problem of plastic pollution in the watershed and ocean, Debra used curriculum from Washed Ashore and then took her students on a field trip to the exhibits in Bandon. “The students got to work on pieces for a condor sculpture, and they just thought the museum was the coolest thing they had ever seen.” said Debra. “They were thrilled to be there.”

To prepare for their trip to Washed Ashore, local artist Elizabeth Roberts from Make Art Not Trash visited the students in their classroom. Her presentation about marine debris and the conversations that followed helped set up the students to understand what they would be seeing during their out of classroom experience. “They all know what a gyre is now,” Debra reported, “and they were able to match the artistic mural of gyres that they saw on the wall at Washed Ashore with the NOAA pictures they had seen back in the classroom.”

In February, Debra’s students conducted experiments to learn more about the characteristics of marine debris. They made hypotheses about whether different types of plastics were likely to sink or float in water, and then tested their ideas. They observed how plastics can hang in the water column and create a “soup”, how bottles full or empty behave differently, and how plastics might look like food to wildlife.

Late in the month, the students took a field trip to the new state-of-the-art Gold Beach Sewage Plant, as well as to the Water Treatment Plant located 5 miles upriver.

The students found out the differences between the two plants, and learned that their drinking water comes from the Rogue River.

“We are in the Rogue River watershed.”

Two Plants: One processes wastewater from people’s houses, and one gives us clean water to drink.

Back at school, the 5th graders spent time outside exploring Riley Creek and collecting macroinvertebrates. These “water bugs” helped them better understand the health of the creek.

By March, the students were ready to brainstorm the issues they wanted to explore further. They discussed their interests and ideas, formed groups, and narrowed down the topics to a few main projects:

  1. Dog Poop – How does dog poop that is not picked up affect the school field, grassy play areas, and stormwater that flows to the ocean? This group was interested in coming up with policies, outreach messages, and other strategies to change the behavior of dog owners. 
  2. Marine Debris Art – How can we help the public understand the problem of marine debris? This group was interested in creating art projects that communicate marine debris impacts and solutions.
     – See examples of projects
  3. Beach Clean Up – What can students do to remove debris from local beaches? This group was interested in working with SOLVE to organize and advertise a beach clean-up event.
  4. PSAs – What kinds of things can people do to protect the environment? This group used to create digital media public service announcements.
     – See examples of projects here and here
  5. Inventions – What solutions could we design to address the problem of plastic pollution? One team in this group focused on ideas for inventions that would keep plastics from going down storm drains, and another team worked on designing an instrument that would separate microplastics from sand.

Today, as school has transitioned to distance learning, Debra and her 5th grade students remain enthusiastic about the topics they have been working on together. “We had just begun working when the pandemic hit” said Debra. Unfortunately, plans for additional field trips were canceled, and student projects were left in a variety of stages when schools closed. To see some of the projects students have been working on this year, visit this Student Work Folder.  For now, the Riley Creek team agrees: “We really enjoyed learning about watersheds!”

Reedsport Third Graders Learn About Watersheds through Meaningful Field Experiences

By Cait Goodwin, Oregon Sea Grant

Think back to when you were in elementary school. Did you participate in a field experience that was so impactful you can still remember it today? “Out of classroom” experiences provide teachers and students the ability to explore local places and relevant issues through hands-on activities and interactions with community partners. These meaningful learning experiences build exposure, connection and curiosity, and often resonate with students well beyond the trip.

Third grade teachers Cristina Bettesworth and Anna Villegas from Highland Elementary School in Reedsport have spent the 2019-20 school year attending multiple professional development workshops to learn strategies for providing meaningful watershed-focused experiences for their students. With guidance from local partners at Oregon Sea Grant and South Slough Reserve, they designed a learning unit filled with lessons and field trips that helped students learn about coastal ecosystems, human impacts, and stewardship. These Meaningful Watershed Educational Experiences (MWEEs) are part of the MWEEs by the Sea project, funded by NOAA Bay-Watershed Education Training program.

MWEE Professional Development

Cristina and Anna planned their third-grade unit together around three main topics: watersheds, salmon, and marine debris. Each topic was introduced in the classroom, followed by hands-on field experiences and connections with environmental professionals that served to further solidify and expand on student learning.


A watershed is the area of land where precipitation collects and drains off into a common outlet, such as into a river, bay, or other body of water.

After students were introduced to the topic of watersheds in the classroom, they took a field trip to South Slough National Estuarine Research Reserve in Charleston in February. With the help of South Slough staff and volunteers, students explored the flora and fauna of the watershed. The students observed how the coastal forest stream is connected to the estuary, experiencing the components of a watershed first-hand as they hiked down from the ridgetop.

To expand on their knowledge of different watersheds, they also visited other sites, including a local beach. After observing different watersheds in person, the students were able to head back to the classroom and create clay models of regional watersheds to show how water flows through local systems.


Given the importance of salmon as a coastal resource, the Highland Elementary teachers knew it would be a natural fit to incorporate salmon studies into their MWEE unit. Salmon migrate between inland streams and the open ocean, showing students another way that land and sea are connected. In addition, parts of salmon life cycles can be experienced in the classroom, enabling students to study life cycles, an important 3rd grade learning standard!

With the help of volunteers from the Gardiner STEP (Salmon Trout Enhancement Program) facility and Oregon Department of Fish and Wildlife STEP biologist Evan Leonetti, the students set up tanks for hatching salmon eggs in their classrooms. Students collected water quality and other data and observed the salmon life-cycle in action as the eggs hatched and grew. When the fish were big enough, they were placed in a transfer tank and taken back to the STEP facility.

In addition to hatching eggs in the classroom, the third graders headed off-school grounds and toured a hatchery, visited local salmon habitat, and some students even travelled to Salem to discuss salmon sustainability in south coast rivers.


Marine debris is any solid, persistent, human-created waste that has been deliberately or accidentally introduced into a waterway or ocean.

To engage their students with a human impact that they could not only see and relate to, but also do something about, Cristina and Anna built lessons around the topic of marine debris. The students started this section by learning and researching about marine debris, answering question like: What is it? Where is it? and What are the impacts and possible solutions to the problem of marine debris?

“Sometimes garbage ends up in a stream or river
and will flow into the ocean.”

– Annabelle A., Third Grade, Highland Elementary

To further excite students, teachers arranged to have Elizabeth Roberts from Make Art Not Trash visit their classroom. She shared her experiences cleaning up marine debris from remote beaches in Alaska, Hawaii, and Maine, and told the students about the ways she uses art to help people understand the issue.

“Marine debris is a big problem that affects all of us. It happens in all waterways and is not only a problem in the ocean. We can all do our part to solve the marine debris problem. We just have to pick up trash and make sure our trash gets into the correct places.”

– Brody S., 3rd Grade, Highland Elementary

Prepared for their field experience, the Highland Elementary 3rd graders took a field trip to Bandon, Oregon, to conduct a beach clean-up at Seven Devils State Park, and to visit the marine debris art exhibits at Washed Ashore. The students took the marine debris that they collected from the beach back to school, separated the trash by types (plastics, microplastics, foam, nurdles, etc.), and graphed their results so they could see what types of debris were most commonly found in their samples. Inspired by the art they had seen from community partners, students used some of the marine debris they collected to create their own art projects. In addition, they wrote essays about the problem of marine debris to help explain marine debris impacts and solutions to others.

“We can help the marine debris issue by picking up our garbage and cleaning our beaches.”

– Bodhi L., 3rd Grade, Highland Elementary

Today, the students are working on creating and sharing their essays, art projects, displays and slide presentations with others. You can see some of the student work generated by this project here.

“We can help deal with the problem of marine debris by not using plastic products. We can reuse products so that they don’t end up in the ocean.”

Family STEM: Rube Goldberg Machines

By Lisa M. Blank, Oregon Coast STEM Hub

This post was created during Spring 2020 to help students and families engage in STEM together while staying at home. But you can use these ideas in the article any time!

Example of a Rube Goldberg machine

Rube Goldberg machines use a series of chain reactions to perform a simple task in the most ridiculously complicated way. In fact, the more complicated the better.

Rube Goldberg cartoon of a self-operating napkin

Why are these contraptions called Rube Goldberg machines? Because the idea began with a man named Rube Goldberg. He was an engineer turned cartoonist whose most famous cartoons chronicled “The Inventions of Professor Lucifer G. Butt.”

Today, Rube Goldberg machines are not just whimsical cartoon images, but are required projects in many engineering programs across the US and a growing national obsession. Learn more about Rube Goldberg and how he viewed his cartoons as social commentary.

To join in the fun and support your family in designing and building your own Rube Goldberg machine (and possibly picking up the laundry), follow the steps below.


Spark your family’s interest in building a Rube Goldberg machine by sharing this video about someone who uses one to serve himself a piece of cake.

Challenge your family to watch the video a second time with an eye for the materials and strategies used.

Don’t be intimidated! Your family’s Rube Goldberg machine need not be as complex as The Cake Server. (Also, we don’t recommend using open flames in your design!) Check out these cool builds by young learners:

And these by elementary-aged learners:


What will your machine do? As a team, decide what problem your family would like to solve. If this is a struggle, consider sharing some of the ideas below.

Depending on the ages of your team members, you can set a minimum and/or maximum number of steps to solve the problem.

FUN FACT: In the national Rube Goldberg Machine Contest, engineering college students compete to design a machine that uses the most complex process to complete a simple task. Competing machines must be composed of a minimum of 20 steps and a maximum of 75, and they must complete their run in under two minutes. Teams are permitted to use no more than two air compressors, power cords, or water hoses. Elements of the machine may not travel beyond a 10-square-foot footprint, and machines can be no more than eight feet tall.


  1. Sketch out your machine before building it.
  2. Identify the materials you need. Here is a suggested material list from Tinkerlab.
  3. Start building! Test your designs as you go and make adjustments as necessary.
  4. If your team gets stuck, here are some Rube Goldberg techniques you can try:

Explore how Rube Goldberg machines demonstrate Newton’s Laws.


Newton's Cradle

First Law: An object at rest stays at rest. An object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. 

In other words, if an object is not moving, it will not start moving by itself. If an object is moving, it will not stop or change direction unless something pushes it.

Image used under license from

F = ma

Second Law: Force is equal to the change in momentum with a change in time. 

In other words, objects will move farther and faster when they are pushed harder.

Image used under license from

Example of Newton's Third Law

Third Law: For every action there is an equal and opposite reaction. 

In other words, when an object is pushed in one direction, there is always resistance of the same size in the opposite direction.

To learn more visit:

Challenge your family to find examples in your team’s machine that demonstrate each of Newton’s Laws.

For example, let’s take Newton’s Third Law: For every action there is an equal and opposite reaction. In the video below, how can you use Newton’s Third Law to explain why the dominoes failed to fall in certain places?

Answer: Without an action or force, there can be no reaction.


1. Make a video of your creation and share it on the Oregon Coast STEM Facebook Page, or email a YouTube or Vimeo video (set to Public view). We can’t wait to see it!

2. Is your family tired of washing their hands? Give it a new twist by joining a Rube Goldberg Challenge.

It has now been a few days since we returned from our four-day cruise on the R/V Oceanus, so I have had ample time to reflect on my experience. More than anything else, I believe that this opportunity has helped show me the value in demonstrating patience while conducting work in the field.

In particular, this concept was impressed on me by Dr. Leigh Torres and her Ph.D. student Dawn Barlow while conducting cetacean surveys from the ship. At times during our surveys, the vessel would proceed for hours across the ocean without the slightest indication of any whales. Eventually, we would sight an individual off on the horizon; then, within the span of perhaps 30 minutes, we would find our ship surrounded on all sides by so many humpbacks that it became difficult to keep track of them all! I soon realized that, inevitably, the monotonous stretches of empty ocean we traversed would reward us with the sight of the animals we sought so much. And the animals were always a treat to see; I truly enjoyed the chance to observe the whales we saw each day.

Of course, our time during the cruise wasn’t solely devoted to whale surveys. There were other lessons in the value of patience each time we took samples of the ocean floor, gathering information on benthic ecology. To take samples of the ocean floor at various locations on the cruise, we used a winch at the stern of the ship to lower a box coring device that would return a scoop of sediment to the surface.

Then, after each sample was recovered on the ship’s deck, our job became the rather tedious work of picking out any small invertebrates that were carried up along with the sediment. This prepared the biological contents to be analyzed later back on shore.

It could be monotonous work, but I actually found the job to be incredibly fulfilling. Each sample became almost like a scavenger hunt, and it was fun to come across the many different unique species of annelids, arthropods, cnidarians, echinoderms, and molluscs. As I changed out of my hard hat and waterproof gear at the end of each sampling session, it felt great to have accomplished something that would further our understanding of the ocean floor – even if each sample demanded a significant investment of time to process.

Looking back on my experiences this past week on the R/V Oceanus, I feel exceedingly grateful to have been able to participate in this special opportunity. One reason I was so keen to be a part of this research cruise is because I am currently in the process of considering which paths to pursue in my future. My experience these past several days at sea has helped me realize that this is a line of work that I might be interested in continuing, and this will likely play an important role in my ultimate choices in the coming months.

By Abigail Kirby

My name is Abigail Kirby and I am writing this post while aboard OSU’s R/V Oceanus! Last Spring at the end of my junior year of high school I applied to be a part of this research cruise because I am absolutely enthralled with the ocean and everything it has hidden beneath its surface. My passion for all things marine bloomed in me at a very young age thanks to the beautiful South Slough Reserve, nestled on the Coos Bay of the Southern Oregon Coast. In the summer, I am hired on annually at the slough to help lead summer science camps as an education intern. Activities at camp often include trekking around the trails, exploring the beach, and conducting water-related experiments.

On board the ship, there are many graduate students and scientists working on separate projects and experiments. Notable among them is Dr. Leigh Torres, who is working to study the effects of human noise on gray whales by collecting samples of their defection events (poop) then analyzing these fecal samples for hormones that may indicate their stress levels. Also on board is Jessica Porquez, an OSU researcher who is studying seabird distribution and abundance, identifying individual species and recording their locations. And the esteemed Dr. Sarah Henkel (who I first had the privilege of encountering during a lecture at OIMB in July), a benthic ecologist, who conducts surveys of the ocean bottom and the animals that live there at the designated PacWave energy test site.

One of the best ways to test what is at the bottom of the ocean is through a method called box coring. Bolted to the stern of the Oceanus is an A-frame that is able to lift and deploy the heavy metal box that is sent to collect a sample of sediment from the seafloor. Many hands are required in deploying and retrieving the device. First, someone must turn on the A-frame and run the hydraulics while two other hands guide the box corer over the back of the boat. The device is lowered to the bottom where a trigger releases, and the jaws close, quickly enclosing the sediment inside the core. Using the power of hydraulics, it is then pulled up and retrieved using two long poles with a rope and hook set-up. Two hands hook the line over the handles and guide the box back into its resting place while the A-frame is maneuvered back to its upright position.

Once the sample is back in its stand, we open the double-doors on the top, and reach in with a centimeter ruler. We measure the depth of the sediment from top to bottom, and then also collect a bit of the surface in a small, marked container. The jaws are then forced open, releasing the sediment into a bucket that is placed underneath. From there it is transported to a sieve that is able to sift out the sand, leaving the organisms and solid debris behind. Using forceps, critters are put into a larger container which will be preserved to study later. This process is repeated for each core.

Some of the sea creatures found in the samples where an assortment of sand dwelling worms, proboscis and all, brittle stars and brittle star bits, small bivalves, and tiny little sea snails.

Although I do love marine science, it is not necessarily what I will choose to pursue as a career, or at least not directly. My goal is to study infectious diseases, especially those of the viral kind and the “spillover” effect that allows them to jump from animal host to our own species. I’d like to be able to make conclusive connections between emerging viruses and the climate change that humans have imparted on our planet. I hope to one day study the spillover effect between humans and marine life, and then establish a direct link to our climate pollution.

Overall, this trip has been a blast and I am thankful to each and every person who helped get me here.

By Genevieve Coblentz-Strong

My name is Genevieve and I am a senior in the Early College High School program. I have always had a strong interest in the ocean, and I have wanted to pursue a career in oceanography since seventh grade.

I chose to apply to this R/V Oceanus research cruise for the opportunity to work with scientists doing various research projects and to get the opportunity to meet fellow high school and undergrad students who share my passion and excitement for the ocean. I have not been disappointed! All the students on board have gotten hands-on experience deploying the CTD, box core, and the plankton net, while also learning how to spot and identify marine mammals and sea birds. I can’t imagine a better way to teach students about the ocean and what it takes to be a researcher.

Yesterday, we spent the entire morning cruising on the Oceanus looking for whales. Finally, in the early afternoon, we spotted some blows on the horizon. As we got closer, more and more whales started appearing and they were identified as humpbacks. The swell was big, but we braved the waves to go take ID photos of the humpbacks. We boarded a small boat aptly named the Red Rocket. After a few minutes of searching, we came up upon a group of three humpbacks. It was so cool to see the whales up close and I really got an appreciation for how big they are. All three humpbacks fluked at the same time, so we were able to get great ID photos! It was an amazing experience to be able to work with researchers and see the whales that close to the boat. The chief scientist on board has a permit that allows the Oceanus and Red Rocket to approach the whales. It is illegal to approach the whales if you don’t have a permit.

Today, we saw lots of mola mola sunfish, egg yolk jellies, and shearwater birds. Some of the science party was sitting downstairs resting when a text came through from the flying bridge, the viewing deck where we watch for marine mammals and seabirds; orcas had been spotted! Everyone dropped what they were doing and rushed to the flying bridge. There, four orcas swam by the boat and put on a quick show for us before they were on their way again. Before they left, they swam right under the Oceanus and we could see them under the water! It was very exciting! Right before dinner, we spotted our first whales of the day (orcas are dolphins), a humpback mother and calf pair! I can’t get over how incredible these animals are! We waited for the mother and calf to surface a few more times before we headed off in search of more whales.

Orcas, or “killer whales”, are the largest member of the dolphin family.

I have learned so much in the past few days! This research cruise has allowed me to explore part of what it takes to be a research scientist and I look forward to the possibility that I could someday work with these scientists and fellow high school students again.

My name is Ashley and I am an undergrad who is a part of the science party here on the Oceanus. I am a sophomore at Oregon Coast Community College and currently enrolled in the Aquarium Science Program. My passion for marine science first began when I was little and attended Hatfield Marine Science Center Day Camps. I attended every year until I “aged out.” Now I am doing everything I can to pursue my passion, which includes this research cruise. Fortunately, I was chosen to be a member of the science party on this vessel and am learning all types of new things, such as surveying whales, sea birds, taking box core samples, and collecting/identifying plankton.

We get to work with experts and do a lot of hands on work, which is totally awesome. Today we began with a really yummy breakfast, went over some safety rules, and ran some drills. This ultimately resulted in us trying on large red survival suits and using a fire hose. Next we found ourselves at the stern of the boat collecting box core samples (grabbing sand off the ocean floor) and digging out organisms that reside in the sediment.

Before we knew it, we were up on the “flying bridge” with binoculars in our hands surveying the vast ocean for any signs of whales. There were so many humpback whales breaching, coming up and breathing, and showing off their flukes for us. This was great because the scientists’ goal was to capture pictures of the unique underside of the whales’ flukes.

We left that station for a moment to fuel up our bodies with some delicious lunch and made our way back up to the whales when we finished. Another task we helped with was surveying/identifying sea birds which was really fascinating to learn the methodology. I originally thought you would identify the birds based off their plumage, but it turns out their flight pattern helps most, along with some other physical features such as bill length.

The most exciting adventure today was the students got to pursue whales in a smaller inflatable boat. The whales were so close to us it was truly magnificent and something I will never forget. The purpose behind this was to, again, try and snap photos of their flukes to identify individual whales.

After dinner we made way to the side of the vessel and deployed bongo nets which would allow us to gather plankton. We brought our samples back into the vessel and began to study them under the microscopes to attempt to identify them.

There were so many neat little creatures swimming around in our petri dishes, like comb jellies, copepods, shrimp larvae, amphipods, and many more. The most interesting thing I got to observe was all the microplastics we also found.

I wasn’t surprised because I knew that our oceans are contaminated with plastics, but it was just very eye opening to see how bad it truly is.

We finally ended our day by coloring Styrofoam cups with permanent markers to send down to the bottom of the ocean and shrink under the enormous pressure. Overall the first day was jam-packed with fun activities and now we are all ready to rest and do it all over again tomorrow.
