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.

Science Pub Corvallis is sponsored by OSU’s TERRA magazine

Sea Grant survey: Coastal professionals, managers concerned about climate change

Posted on by

High surf at Fishing RockThe American public may be divided over whether climate is changing, but coastal managers and elected officials in nine states say they see the change happening—and believe their communities will need to adapt.

That’s one finding from a NOAA Sea Grant research project, led by Oregon Sea Grant and involving multiple other Sea Grant programs, which surveyed coastal leaders in selected parts of the nation’s Atlantic, Pacific, Gulf and Great Lakes coasts, as well as Hawaii.

Three quarters of coastal professionals surveyed – and 70% of all participants – said they believe that the climate in their area is changing—a marked contrast to results of some national surveys of the broader American public which have found diverse and even polarized views about climate change and global warming.

The Sea Grant survey was developed to understand what coastal/resource professionals and elected officials think about climate change, where their communities stand in planning for climate adaptation and what kinds of information they need, said project leader Joe Cone, assistant director of Oregon Sea Grant.  Sea Grant programs in Connecticut, Hawaii, Illinois-Indiana, Louisiana, Maryland, Minnesota, Oregon, and Washington—states that represent most of NOAA’s coastal regions—took part, administering the survey at various times between January 2012 and November 2013.

Register-Guard: Changing ocean chemistry threatens marine life

Posted on by

The Whiskey Creek Shellfish Hatchery on the state’s north coast watched oyster larvae die en masse for three years in a row in the mid-2000s — depriving oyster farms along the entire West Coast of seed oysters.

Florence crabber Al Pazar saw baby octopuses, an inch or two long, climb up his crab lines to escape the sea waters in the 2005 season. When he pulled up his pots, the crab were dead.

Eugene fisherman Ryan Rogers, who drags in great piles of salmon on an Alaska purse seiner, has instead brought up nets full of jellyfish in recent years.

“Sometimes we’ll catch 4,000 or 5,000 pounds of jellyfish. They spray all around. We get stung,” he said. “It makes it difficult to bring your net in. You have to let it go and lose the salmon that are in your net.”

Scientists — including many at Oregon State University — are beginning to define the cause of these events. They call it ocean acidification and hypoxia.

Wind, currents and ocean chemistry conspire to create pools of corrosive waters that can be lethal to key commercial species in Northwest waters — and favorable to some nuisance species, such as jellyfish. …

The Eugene Register-Guard examines what OSU scientists – some of them working with Oregon Sea Grant funding – are learning about the causes and consequences of ocean acidification.

New publication offers insights from a NOAA-Sea Grant project

Posted on by

A new publication from Oregon Sea Grant, Climate Field Notes, distills the results of a multi-year, multi-state SARP-Report-coverproject funded by the NOAA Climate Program Office Sectoral Applications Research Program (SARP).

Oregon Sea Grant led this project, which used a risk-communication framework to help coastal communities respond to the effects of a changing climate. Climate Field Notes documents the results of projects in eight states, including Oregon, Washington, Minnesota, Maine, Maryland, North Carolina, South Carolina, and Florida.

The report includes discussion of social science methodologies, definitions and usefulness of resilience, the roles of leadership and boundary organizations, user-centered communication approaches, and lessons learned from practitioners in the field.

Primary authors of the report are Joe Cone, Pat Corcoran, Miriah Russo Kelly, and Kirsten Winters.

Tsunami STEM Curriculum–uses Ocean Science Systems as pathways to stimulate STEM (Science, Technology, Engineering, and Math) learning to guide students in decision making. Students immerse into STEM through understanding the causes and consequences of a natural disaster such as a tsunami or bioinvasion, learn about their risks, and explore choices and consequences of responses to and preparation for tsunami hazards. http://seagrant.oregonstate.edu/sgpubs/e-13-003

You’re Excluded! An Activity Exploring Technology Changes in the Trawl Industry–includes objectives, method, materials needed, information on trawl fishing, pictures of nets, procedures, activity options, and discussion questions. It also includes instructions on incorporating engineering designs standards for kindergarten through high school. http://seagrant.oregonstate.edu/sgpubs/e-13-002-trawl-industry-curriculum

South coast native oysters may survive acidification threat

Posted on by

Oyster baskets at Whiskey Creek Shellfish HatcheryCOOS BAY – While some West coast oyster stocks are threatened by rising ocean acidity, native oysters on Oregon’s south coast seem to be doing well.

Netarts Bay’s Whiskey Creek Shellfish Hatchery — which produces much of the oyster seed used by commercial farms in the region —has experienced a decline in production that Oregon State University researchers traced directly to ocean acidification.

But biologist Steve Rumrill, director of the Oregon Department of Fish and Wildlife shellfish monitoring program at the South Slough National Estuarine Research Reserve, suspects that the shallow parts of Coos Bay “may be able to act as a sort of buffer,” protecting native Olympia oysters in that area from the shell-destroying effects of ocean acidification.

Another clue could lie in the oysters’ breeding habits, according to George Waldbusser, an OSU biologist who studies oyster reproduction and survival.

“Olympias are brooders,” Waldbusser said, referring to the species’ trait of carrying eggs in an internal chamber for several weeks after fertilization, whereas the Pacific oysters bred in Netarts Bay broadcast their fertilized eggs into the open water, where they are directly exposed to chemical changes at an earlier point in their life cycles, when they may be more vulnerable.

OSU secures critical funding to continue ocean acidification research

Posted on by

Oregon State University will receive funds that will help the West Coast’s shellfish industry in its fight against ocean acidification, thanks largely to the efforts of Oregon state Senator Betsy Johnson (D-Scappoose). Receipt of these funds will give a critical boost to Oregon State University’s and the shellfish industry’s efforts to reduce the negative impacts of ocean acidification on shellfish production.

House Bill 5008 allocated $250,000 to Oregon State University. A portion of the funds will be used to continue OSU’s efforts to improve the resilience of oyster to ocean acidification through its selective breeding program at the Hatfield Marine Science Center in Newport. The remaining funds will be dedicated to OSU’s collaboration with industry leaders at the Whiskey Creek Shellfish Hatchery (see “The Whiskey Creek Shellfish Acid Tests” in the current issue of Confluence) on Netarts Bay as they continue to identify better ways to manage the negative effects of ocean acidification on shellfish larvae.

Oyster shells help restore chemical balance to acid waters

Posted on by

Healthy young oyster spatThe shells of oysters – a commercially important shellfish whose reproduction and growth is threatened by climate-linked ocean acidification – may help counteract the effects of increased local acidity levels, according to a new study of New England’s Chesapeake Bay by a team of researchers led by Oregon State University’s George Waldbusser.

The study, published in the journal Ecology and reported this week in the New York Times , concludes that the buildup of old shells in undisturbed oyster beds – along with the oysters’ waste – can help restore alkalinity to waters that might otherwise be too acid for the shellfish to survive.

Like ocean waters around the world, the Chesapeake has become more and more acidic as a result of rising levels of carbon dioxide in the atmosphere. Now, by studying oyster populations in relation to acidity levels,Waldbusser’s team has concluded that oysters — particularly their shells — can play a significant role in reducing that acidity.

“Oyster shells are made out of calcium carbonate, so they’re sort of like an antacid pill,” said Waldbusser, an assistant professor of earth, ocean and atmospheric sciences at OSU and an author of the study. “In an undisturbed oyster reef, healthy oysters are generating a lot of biodeposits,” a genteel term for excrement, “which helps generate CO2 to help break down those shells, which helps to regenerate the alkalinity back into the environment.”

Ocean acidification is of great concern to commercial oyster growers. Additional  research by Waldbusser and colleague Burke Hales, conducted at an Oregon oyster hatchery, has shown that increasing acidity near commercial shellfish operations inhibits the larval oysters from developing shells and growing at a pace that makes oyster farming economically viable.

Waldbusser is also working on a Sea Grant-funded project to develop Web-based tools that would allow oyster growers and resource managers to better understand how acidification affects larval oysters so they can more effectively adapt, mitigate and adjust their operations to increase oyster survival and growth.
