A new video from Oregon Sea Grant shows how researchers at Portland State University are inspecting the guts and tissues of razor clams and oysters along the Oregon coast for microplastics, which can come from foams, tiny beads in facial creams, synthetic fibers from clothing, and disintegrating plastic bags.

“Our goal is to figure out if we have them in our oysters and clams, and if so, are they at problematic levels?” said Britta Baechler, a PSU master’s student who is working on the Oregon Sea Grant-funded project under the guidance of PSU marine ecologist Elise Granek.

Oysters and clams, Baechler explained in the four-minute video, are indiscriminate filter feeders and so they may ingest a piece of plastic and not be able to get rid of it. Microplastics, which are defined as less than 5 mm, are of concern because they can attract chemicals, which might harm animals if eaten.

With help from the Oregon Department of Fish and Wildlife, Baechler dug up razor clams at nine sites along the Oregon coast and bought oysters at five locations to see if there are areas where microplastics are more prevalent. She collected the shellfish in the spring of 2017 and again this summer to see if microplastics are more common during certain times of the year.

Once the oysters and clams were gathered, they were taken to Granek’s lab at PSU where they were measured, weighed, shucked and frozen so they could later be dissolved in potassium hydroxide. This process leaves a clear liquid that contains only sand and any plastics that may be present. The researchers hope to have dissolved all of the bivalves by the end of September. For the ones that have already been dissolved, they’ve been analyzing the liquefied remains under a microscope to see if they find microplastics, but results are not in yet.

“Ultimately, we’re hoping that this study brings awareness to Oregonians and even visitors to the state of Oregon that plastics that we use in our daily lives make their way into the environment,” Baechler said in the video. “We’re also hoping that our partners, like Oregon Department of Fish and Wildlife and other state agencies, might take this information to learn about hot spots for microplastics to address the problem.”

Video: Studying the relationship between seagrass, nutrients, algae and herbivores

A new video from Oregon Sea Grant shows how researchers are studying how nutrients from agricultural runoff and oceanic upwelling impact the growth of light-blocking algae on eelgrass in bays along the Oregon coast.

With funding from Oregon Sea Grant, they’re also studying how tiny herbivores, such as sea slugs and centipede-like isopods, might prevent eelgrass from being snuffed out by this algae. Additionally, they’re investigating whether these herbivores prefer to eat the native or invasive eelgrass in the bays.

In the six-minute video, Fiona Tomas Nash, a marine ecologist in the Department of Fisheries and Wildlife at Oregon State University, explains that eelgrass is important because it produces oxygen, reduces the impacts of waves, and provides habitat and food for waterfowl, baby fish and crabs.

“Nutrient pollution is one of the main causes of seagrass loss worldwide,” Tomas Nash said in the video. “And so we’re trying to understand if this is a problem in Oregon.”

She said the results of her research may benefit state and federal agencies that deal with food production, fisheries and water quality.

The research is taking place in four estuaries – Coos Bay, Yaquina, Netarts and Tillamook – to quantify how much seagrass there is and determine what aquatic grazers are present, Tomas Nash said.

“We’re doing experiments, both in the field and in the lab,” she said in the video, “where we add nutrients, and we also manipulate the presence or absence of these animals to see how these combinations of more nutrients and different animals can affect the amount of algae that there is and, therefore, the seagrass health.”

Partners in the project include the Oregon Department of Fish and Wildlife, the Environmental Protection Agency and the South Slough National Estuarine Research Reserve.

Summer 2017 “Shop at the Dock” tours in Newport and Warrenton show consumers how to buy in-season seafood

Posted on by

Have you ever wanted to buy seafood right from the boat, but weren’t sure what questions to ask or what to look for? Have you ever stood at a seafood market staring at all the choices but not been sure what was local or in season?

If so, this summer is your chance to learn more about buying seafood. Experts with Oregon Sea Grant and the Oregon State University Extension Service will demystify the process during free, guided dockside tours in Newport and Warrenton that connect seafood lovers with commercial fishermen.

Oregon Sea Grant and Extension have been offering the tours – called Shop at the Dock – every summer in Newport since 2014, but this is the first year the event has expanded to Warrenton. During the tours, participants learn what seafood is in season, how it’s caught, whether it’s sustainable, and how to identify and buy high-quality fish and shellfish. Last year, the tours drew more than 350 people, said Kaety Jacobson, an Oregon Sea Grant marine fisheries specialist with Oregon State University’s Extension Service.

Dates for the remaining Newport tours are July 21 and 28, and Aug. 4, 11 and 18, 2017 with groups departing from dock 5 at 9:30 a.m., 10 a.m., 10:30 a.m. and 11 a.m. each day. The 90-minute tours are free and on a first-come, first-served basis. In Newport, registration is required only for groups of five or more by calling 541-574-6534 ext. 57427.

In Warrenton, the remaining tours will take place Sept. 15, 2017, at 9 a.m. and 11 a.m. and will include a tour of the Skipanon Brand Seafood cannery. Participants will also learn where they can find locally caught fish in local markets. Tours will start at the Warrenton Marina near the harbormaster’s office at 550 N.E. Harbor Place. For the Warrenton event, registration by phone is required for everyone and is on a first-come, first-served basis. To register, call 503-325-8573.

At both sites, participants are advised to wear comfortable walking shoes with traction, arrive 15 minutes early, and bring cash and a cooler with ice. For disability accommodations, please call the numbers above.

New videos encourage boaters to help keep waterways clean

Posted on by

Two new videos from Oregon Sea Grant encourage boaters to help keep our waterways clean by emptying their portable toilets and holding tanks at designated facilities at marinas and short-term tie-up docks.

The videos, “Where to Empty Onboard Portable Toilets in Oregon” and “Where to Empty Onboard Holding Tanks in Oregon,” feature Jenny East, boater outreach coordinator with Oregon Sea Grant and the Oregon State University Extension Service. They are part of her ongoing efforts to educate recreational boaters about the availability of facilities at marinas for disposing of onboard sewage.

Jenny East empties an onboard portable toilet.

The new videos join a dozen others on the subject, available on a YouTube playlist here.

Photos of East and some of the facilities she demonstrates in the videos are available for download from our “Boater Outreach” album on Flickr.

The videos were filmed and edited by Oregon Sea Grant videographer Vanessa Cholewczynski in collaboration with the Oregon State Marine Board.

Oregon Sea Grant director provides update on budget challenge

Posted on by

An open letter from Shelby Walker, director of Oregon Sea Grant, addresses the White House’s proposed elimination of Sea Grant and what it might mean for Oregonians and people in 30 other coastal and Great Lakes states around the country. Below is an excerpt from the one-page letter; you can read the full version at the link provided below.

“Oregon Sea Grant has been a key partner with Oregonians in working towards solutions for complex coastal and ocean issues, including fisheries, hazards, and energy, for over 45 years through research, extension, education, and communication. Nationwide, the Sea Grant program works in 31 states, including Oregon, and two territories to create or sustain more than 20,000 jobs and 2,900 businesses annually. In 2015, the national program’s $67.3 million budget generated an economic impact of $575 million, which was an 854 percent return on investment.”

With Sea Grant funding, engineering students build ‘portable deep core’ that may improve studies of native mud shrimp

Posted on by

A parasitic isopod known as Orthione griffenis is decimating mud shrimp populations in coastal estuaries ranging from British Columbia to northern California. Most surviving mud shrimp populations are heavily infested with the parasite, threatening their existence.

“From Bamfield, Canada, down to Morro Bay, California, the native mud shrimp, Upogebia pugettensis, are either gone or the populations are severely depressed,” said John Chapman, an Oregon State University invasive species specialist who works out of OSU’s Hatfield Marine Science Center in Newport.

Mud shrimp are valuable prey for birds, fish and other animals in estuaries, and some ecologists believe they have provided a steady food source for ocean-bound juvenile coho and Chinook. Mud shrimp are also important to the ecology of estuaries: each day during their feeding, they may filter as much as 80 percent of the estuary’s intertidal water.

Studying the shrimp, which can burrow to depths of two meters, involves extracting them with quantitative sampling devices. These devices traditionally have been either handheld cores and shovels, which can damage the shrimp beds, or a “yabby” pump, which sucks up only medium-sized and large shrimp and is not quantitative. Neither method is reliable for quantifying the most important reproductive sizes, and both often damage shrimp in the process of collecting them.

The solution? Create a new device that’s not only long enough to reach the deepest shrimp, but gentle enough to bring them to the surface unharmed — and also simple enough to allow for rapid, inexpensive sampling by just a few researchers.

To develop the device — a “portable deep core” — Chapman enlisted the assistance of OSU Engineering professors John Parmigiani and Sharon LaRoux, who would oversee the student design teams* and participate in the field testing and implementation. Chapman and Parmigiani also secured $9,000 in funding from Oregon Sea Grant, to help defray materials costs and other expenses.

Between January and May 2017, three student teams, each working on a different design, researched, planned, designed, built and tested the components of their respective devices, and on May 19 they unveiled the working prototypes at OSU’s Undergraduate Engineering Expo. “Each of the three designs will be evaluated and combined over the summer by a graduate student into a single, final prototype,” said Parmigiani.

According to Chapman, the newly designed deep core “will, for the first time, give us access to the entire range of burrowing shrimp populations, and let us gather the information we need to help slow or reverse the mud shrimp’s decline.”

“Shop at the Dock” in 2016 for fresh seafood, fisheries education

Posted on by

July 11, 2016

NEWPORT – What started as an experiment to help bring new customers to fishermen who sold seafood off their vessels has quickly become a favorite summer activity for a growing number of locals and visitors in Newport.

shop-the-dockSponsored and run by Oregon Sea Grant in partnership with the Port of Newport, “Shop on the Dock” in 2016 is entering its third summer of offering free, guided educational tours of Newport’s commercial fishing docks. Shoppers learn a bit about the fisheries, meet the people who catch the fish, and have an opportunity to buy the freshest salmon, tuna, halibut and crab, usually at prices lower than they’d find at their local supermarkets.

The summer of 2016 will see more walks spread over two months – July 15, 22 and 29, and Aug. 5, 12 and 19 – and having multiple walks (at 9:30 a.m., 10 a.m., 10:30 a.m. and 11 a.m.) each date.

“It’s like going down to the docks with a friend who knows the seafood – and knows the fishermen,” said Kaety Jacobson, Sea Grant’s Newport-based Extension fisheries specialist, who runs the program. “We make it easy for people.”

New Sea Grant publication encourages collaborative engagement

Posted on by

A new publication from Oregon Sea Grant, Collaborative Science-Stakeholder Engagement, encourages collaboration among scientific disciplines and extending that collaboration to include participants outside the academic world.

The 20-page publication outlines various types of collaboration, both among researchers of diverse disciplines and among reseh16001-coverarchers and stakeholders. It explores collaborations seeking to achieve different goals in natural-resource research and management (sustainability, climate change adaptive management, decision-making tool development, alternative futures exploration). In also provides examples of stakeholder engagement in these contexts for the understanding and management of various natural resources, and summarizes literature from other research on science-stakeholder engagement elements.

Finally, the guide lists the lessons learned, necessary elements and impacts from these case studies.

The guide is intended as a resource for anyone interested in connecting science producers and science users. It summarizes literature from a broad swatch of research with science-stakeholder engagement elements.

The research was conducted and text written by Laura Ferguson, Oregon State University Marine Resource Management program, with review and contributions by Samuel Chan, Mary Santelmann and Maria Wright.

Collaborative Science-Stakeholder Engagement is available as a free, downloadable PDF here.

West coast science panel issues report, call for action on ocean acidification, hypoxia

Posted on by

P2 - Logo 1Although ocean acidification and hypoxia are global phenomena, the US-Canada West Coast will face some of the most severe changes, with impacts extending through marine food webs and threatening ocean-dependent industries and coastal communities.

So says a report released today by a panel of 20 scientific experts from Oregon, California, Washington and British Columbia charged with summarizing what’s known about the problem and what options the region has for coping with it.

Major findings:

  • Acidification and hypoxia will have severe environmental, ecological and economic consequences for the West Coast, and will require a concerted regional focus.
  • Global carbon emissions are the dominant cause of acidification
  • There are actions that can be taken to lessen exposure to acidification, and to enhance the ability of ecosystems and organisms to cope.
  • Investing in acidification science will expand the available management options.
  • Inaction now will reduce those options and impose higher costs later.

Among the panelists are Oregon State University researchers Frances Chan, who co-chaired the group, George Waldbusser, Burke Hales and Jack Barth, all of whom have received research funding support from Oregon Sea Grant.

The panel’s report provides a comprehensive analysis, along with technical guidance for ocean program managers and a summary of foundational science about how acidification and hypoxia affect individual species, populations and ecosystems, the science needs of managers and challenges and opportunities in the realm of water quality.
