Science Pub to explore the future of oceans

Posted on by

CORVALLIS – The effects of global climate change and associated threats to the oceans are the topic for the May 12 edition of Science Pub Corvallis, presented at the Majestic Theatre, 115 SW 2nd St., from 6-8 pm. Admission to the public talk is free.

Andrew Thurber, a post-doctoral fellow in Oregon State University’s College of Earth, Ocean, and Atmospheric Sciences (CEOAS), will lead the discussion in an informal presentation where questions are welcomed.

The Earth’s oceans face multiple climate-related stresses: warming temperatures, low oxygen, acidification and a lack of biological productivity. As marine ecosystems respond, the consequences could be felt directly by about 2 billion people whose lives depend on ocean fisheries and other resources. Those are among the results reported by an international team of 29 scientists who studied the influence of climate change on marine systems from the poles to the Equator.

Thurber, who holds a Ph.D from the Scripps Institution of Oceanography, helped to conceive the study and was a co-author of the report that appeared in October 2013 in the journal PLOS Biology. “What is really sobering about these findings is that they don’t even include other impacts to the world’s oceans such as sea level rise, pollution, over-fishing, and increasing storm intensity and frequency,” he says. “All of these could compound the problem significantly.”

Thurber will discuss the study and actions needed to avert the most significant changes.  His research focuses on deep-sea ecosystems, particularly the role of invertebrates in recycling nutrients and sequestering carbon. He has conducted experiments under seasonal sea ice in Antarctica and explored communities that live around methane seeps near New Zealand and Costa Rica.

ROV teams compete for regional honors

Posted on by

Taft High School ROV team launches Ocean's Hope at 2013 competitionLINCOLN CITY – —More than 150 elementary, middle school, high school and college students in 27 teams bring their underwater robots to the Lincoln City Community Center on May 10 to compete in the annual Oregon Regional MATE Remotely Operated Vehicle (ROV) contest. The event is free and open to the public.

The teams, which have spent the past few months designing and building the underwater vehicles, join students around the world participating in 23 regional contests supported by the Marine Advanced Technology Education (MATE) Center. Qualifying participants will earn the chance to advance to MATE’s International ROV Competition June 26 – 28, at the Thunder Bay National Marine Sanctuary in Michigan.

Coordinated by Oregon Sea Grant, the Oregon Regional MATE ROV Competition encourages students from Astoria to Bandon and Bend to The Dalles, to develop and apply science, technology, engineering and math (STEM) skills as they work collaboratively to create working ROVs—tethered underwater robots used in ocean exploration, scientific research, and marine technology industries—to complete missions that simulate real-world tasks.

This year’s competition is thematically organized around the role of ROVs in exploring and documenting shipwrecks and conserving national maritime heritage sites such as the Thunder Bay National Marine Sanctuary, where more than 50 shipwrecks are submerged. The competition helps students understand how chemical, biological and physical conditions can affect such archaeological sites.

Competing teams participating will perform a variety of underwater mission tasks, piloting their ROVs to identify a simulated shipwreck, collect microbial samples, inventory invasive species and remove debris. Students are challenged to think like entrepreneurs and form companies that develop creative solutions for engineering and constructing an ROV to document and explore a newly discovered wreck site. During the process, the students develop the teamwork, creative thinking and problem solving skills that make them competitive in today’s global workplace. The project requires them to solve problems in new and innovative ways, work as part of a team and understand all aspects of business operations—important 21st century skills.

Teams from the following schools and organizations are participating in the competition: Bandon High School, Cheldelin Middle School (Corvallis), Clatsop Community College (Astoria), Eddyville Charter School, Life Christian School (Aloha), Linn-Benton Community College (Albany), Meek Pro Tech High School (Portland), Oregon State University (Corvallis), Summit High School (Bend),,Taft 7-12 (Lincoln City), Tahola Middle School (Tahola, WA), The Dalles High School, Toledo Elementary, Toledo Jr/Sr High School, Waldport High School and Wasco County 4-H.

The Oregon Regional MATE ROV Competition is supported by many sponsors, including Oregon State University, the Oregon Coast Regional STEM Center, Lincoln County School District, the Marine Technology Society-Oregon Chapter, the Siletz Charitable Contribution Fund, the Cascade Chapter of the Association for Unmanned Vehicle Systems International, and Tanger Outlet Mall. Local marine technology professionals and engineers volunteer as judges for the competition, evaluating the students’ ROVs, poster displays, and engineering presentations. Numerous other volunteers donate their time each year, serving as divers and support staff for the competition, making it a community-wide effort.

Ongoing study finds more albacore with traces of Fukushima radiation

Posted on by

Jason Phillips bleeds an albacoreAlbacore tuna caught off the Oregon shore after the Fukushima Daiichi power station in Japan was destroyed in a 2011 earthquake had slightly elevated levels of radioactivity but the increase has been minute, according to a newly published study.

In fact, you would have to consume more than 700,000 pounds of the fish with the highest radioactive level – just to match the amount of radiation the average person is annually exposed to in everyday life through cosmic rays, the air, the ground, X-rays and other sources, the authors say.

Results of the study are being published in the journal Environmental Science and Technology.

“You can’t say there is absolutely zero risk because any radiation is assumed to carry at least some small risk,” said Delvan Neville, a graduate research assistant in the Department of Nuclear Engineering and Radiation Health Physics at Oregon State University and lead author on the study. “But these trace levels are too small to be a realistic concern.

“A year of eating albacore with these cesium traces is about the same dose of radiation as you get from spending 23 seconds in a stuffy basement from radon gas, or sleeping next to your spouse for 40 nights from the natural potassium-40 in their body,” he added. “It’s just not much at all.”

Researcher: Changes in processing, handling could cut commercial fishing injuries

Posted on by

CORVALLIS, Ore. – Handling frozen fish caused nearly half of all injuries aboard commercial freezer-trawlers and about a quarter of the injuries on freezer-longliner vessels operating off the coast of Alaska, new research from Oregon State University shows.

Many of those injuries and others aboard the two types of vessels could be prevented with the right interventions, and the research methods used in the study could help identify and reduce injuries and fatalities in other types of commercial fishing, said researcher Devin Lucas. His findings were published in the “American Journal of Industrial Medicine.”

“We’ve drilled down to such a detailed level in the injury data that we can actually address specific hazards and develop prevention strategies,” said Lucas, who recently received his Ph.D. in public health from OSU’s College of Public Health and Human Sciences and works for the National Institute for Occupational Safety and Health (NIOSH) in the Alaska Pacific office.

Lucas’ study is the first scientific assessment of the risk of fishing on freezer-trawlers and freezer-longliners. In both types of vessels, the processing of fish is handled on-board. The vessels had reputations for being among the most dangerous in commercial fishing in part because of a few incidents that resulted in multiple fatalities.

However, an analysis of 12 years of injury data showed that fishing on the freezer vessels was less risky than many other types of commercial fishing, which is one of the most dangerous occupations in the United States, Lucas said. The rate of injury on freezer-trawlers was about the same as the national average for commercial fishing, while the rate aboard freezer-longliners was about half of the national average.

“The reality is that many fisheries elsewhere in the U.S., including Oregon Dungeness crabbing, are much more dangerous,” Lucas said.

Sea Grant “Stone Soup” lesson plan featured in national science ed newsletter

Posted on by
Stone Soup strip

A new Sea Grant lesson plan that employs lessons from a popular comic strip to teach middle-school and elementary students about the perils of releasing classroom pets into the wild is featured in the spring newsletter of FOSS, a nationally prominent program of research-based science learning for elementary and middle-school classrooms based at the Lawrence Hall of Science, University of California, Berkeley.

The newsletter has been mailed to subscribers, and will be featured at a National Science Teachers Association meeting later this week.

Developed by Oregon Sea Grant’s invasive species team and collaborators in Oregon, Washington and California, the Stone Soup Cartooning and Invasive Species lesson encourages youngsters to use art and language skills to learn about biology, ecology, invasive species, and the importance of learning from one’s actions. Students study and discuss the cartoon, and then write and illustrate their own comics about some aspect of invasive species.

The idea for the lesson plan was born from a series of comics drawn last year by Jan Eliot, the Oregon artist who writes and draws the popular, nationally syndicated Stone Soup strip. Eliot, who once wanted to study marine biology, wanted to call attention to the ecological damage that can happen when well-meaning teachers and students release classroom pets such as crayfish and turtles into the wild. She called on Oregon Sea Grant’s invasive species specialist, Sam Chan, to make sure she got the science right.

The result was an entire storyline, which ran in newspapers across the country last September, featuring ongoing Stone Soup character Alix – a budding child scientist who doesn’t always consider the consequences of her acts – and a pet crayfish named Pinchy.

With the blessing of Eliot (and her syndication service) Chan and his partners in the West Coast Sea Grant Regional Aquatic Invasive Species Alliance developed the new lesson plan and associated learning activities to build on the cartoons’ success, and provide teachers with tools to incorporate the subject into their science teaching. The plan is part of a nationwide project to educate teachers – and suppliers of classroom animals – about the ecosystem damage released non-native pets and cause, and other humane alternatives to freeing them in the wild.

Besides conducting ongoing research to improving the learning and teaching of science, FOSS is one of two major US suppliers of K-8 science kits that bases its STEM curricula on learning with live specimens.

Tsunami Preparedness Week – Are You Prepared?

Posted on by

Pat Corcoran visits Japan to see aftermath of tsunami, 2012It’s Tsunami Preparedness Week, and Pat Corcoran wants to make sure people who live on -and visit – the seismically active coast know what to do when the big wave hits.

Corcoran, Oregon Sea Grant’s coastal hazards specialist, is featured this week on the NOAA Sea Grant home page, and says the single most important thing to know about tsunamis is that they can happen unexpectedly. “Whenever visiting the ocean shore, be prepared to move to high ground if you experience an earthquake,” says Corcoran. “Also important to know, is the earthquake and tsunami experience is different depending on where you are in the world. In the Pacific Northwest of the USA, our natural warning for a big tsunami is a big earthquake.” Elsewhere in the world, people may not even feel the ground shake.

Corcoran has spent more than a decade educating and working with coastal residents and communities to help them prepare for coastal hazards, from storms to the inevitability that a large earthquake – likely with an accompanying tsunami – will strike the region in the not-too-distant future. The challenge, he says, is getting people to understand that they need to prepare now for an event that has never happened in their lifetimes, or perhaps those of their parents or grandparents.

Fossil Fest rescheduled for April 26

Posted on by

Oregon coast fossilsNEWPORT –  Guy “Oregon Fossil Guy” DiTorrice returns OSU’s Hatfield Marine Science Center on Saturday, April 26, for this year’s edition of the popular Fossil Fest – rescheduled from early February due to snow.

DiTorrice, a longtime fossil hunter and lecturer, joins Dr. William Orr for special presentations about fossil finds in Oregon and elsewhere. Mike Full, a local Pleistocene fossil hound, and Newport’s own Kent Gibson will show exhibits of amazing Oregon fossils, and the American Research Group will host additional displays and hands-on activities for the whole family. Visitors are invited to bring their own “mystery fossils” for expert identification.

Schedule:

  • 11:30 am – Guy DiTorrice speaks about seeking and finding dinosaur fossils at the Montana ranch where parts of Jurassic Park were filmed, including Duckbill (Hadrosaurus) dig sites .
  • 1:30 pm – Dr. Bill Orr, “In Search of the Conodont Animal” – a talk about the recent discovery of a small fish-like animal that has for 150 years been a mystery to the paleontology community. The Conodonts are one of the most important guide fossils to the entire Paleozoic interval of time: a duration of 300 million years, and the discovery has stirred immense interest among paleontologists.

All day:

  • Mike Full’s “Willamette Valley Pleistocene Project” display captures a glimpse of 50,000 years of prehistory in our own backyard. Giant bison and wooly mammoth fossils will be on display.
  • Kent Gibson, who has provided fossils to the Smithsonian’s collection will display a cross-section of fossils found in Lincoln County, including dolphin skulls, scallops, and whale vertebrata.
