Oregon Sea Grant: Coastal science serving Oregon
Updated: 2 days 7 hours ago
Oregon Sea Grant is seeking qualified applicants for four graduate and postgraduate fellowships in marine science and policy.
The NOAA Coastal Management Fellowship (deadline Friday, January 23, 2015) provides on-the-job education and training opportunities in coastal resource management and policy for postgraduate students while assisting state coastal zone management programs. The program matches postgraduate students with state coastal zone programs to work on projects proposed by the state and selected by the fellowship sponsor, the National Oceanic and Atmospheric Administration Coastal Services Center. This two-year opportunity offers a competitive salary, medical benefits, and travel and relocation expense reimbursement. Any student who will complete a master’s, doctoral, or professional degree program in natural resource management or environmental-related studies at an accredited U.S. university between January 1, 2014, and July 31, 2015, is eligible.
The National Marine Fisheries Service/Sea Grant Graduate Fellowship Program in Marine Resource Economics (deadline Thursday, January 29, 2015) expects to award at least two new PhD Fellowships starting Aug. 1, 2015 to students who are interested in careers related to marine ecosystem and population dynamics. The Fellowships can provide support for up to three years for highly qualified graduate students working toward a PhD in quantitative ecology, ecosystem ecology, population dynamics or related fields of study. Fellows will work on thesis problems of public interest and relevance to NMFS under the guidance of National Marine Fisheries Service (NMFS) mentors at participating NMFS Science Centers or Offices. Applicants must be United States citizens, and at the time they apply must be admitted to a PhD program in a relevant field of study at a US institution.
The NMFS/Sea Grant Graduate Fellowship Program in Population and Ecosystem Dynamics (deadline Thursday, January 29, 2015) generally awards two new PhD Fellowships each year to students who are interested in careers related to the development and implementation of quantitative methods for assessing the economics of the conservation and management of living marine resources. Fellows will work on thesis problems of public interest and relevance to NMFS under the guidance of NMFS mentors at participating NMFS Science Centers or Offices. The Fellowship can provide support for up to two years for highly qualified graduate students working towards a Ph.D. in in marine resource economics, natural resource economics, or environmental economics. Applicants admitted to a PhD degree program in resource or environmental economics at a US institution.
Dean John A. Knauss Marine Policy Fellowships (deadline Friday, February 13, 2015) provides a unique educational experience to students enrolled in graduate programs in fields related to marine or Great Lakes studies. The program matches highly qualified graduate students with hosts in the legislative branch, the executive branch, or appropriate associations and institutions located in the Washington, D.C. area. Recipients spend one year working on substantive national policy issues related to marine issues; a stipend is provided. The Fellowship is open to any student, regardless of citizenship, who is enrolled toward a degree in a graduate or professional program at an accredited US institution.
For all four opportunities, completed applications must be delivered to the Oregon Sea Grant program office in Suite 350 of the University Plaza Building, 15th and Western in Corvallis, by 5 pm on the deadline date.Learn more:

The mortality of larval Pacific oysters in Northwest hatcheries has been linked to ocean acidification, yet the rate of increase in anthropogenic carbon dioxide in the atmosphere and the decrease of pH in near-shore waters have been questioned as being severe enough to cause the die-offs.
However, a new study of Pacific oyster and Mediterranean mussel larvae found that the earliest larval stages are directly sensitive to saturation state, not carbon dioxide (CO2) or pH. Saturation state is a measure of how corrosive seawater is to the calcium carbonate shells made by bivalve larvae, and how easy it is for larvae to produce their shells.
It is important to note that increasing CO2 lowers saturation state, the researchers say, and saturation state is very sensitive to CO2; the challenge interpreting previous studies is that saturation state and pH typically vary together with increasing CO2. The scientists utilized unique chemical manipulations of seawater to identify the direct sensitivity of larval bivalves to saturation state.
Results of the study, which was funded by the National Science Foundation, are being reported this week in the journal Nature Climate Change.
“Bivalves have been around for a long time and have survived different geologic periods of high carbon dioxide levels in marine environments,” said George Waldbusser , an Oregon State University marine ecologist and biogeochemist and lead author on the study, “The difference is that in the past, alkalinity levels buffered increases in CO2, which kept the saturation state higher relative to pH.”
“The difference in the present ocean is that the processes that contribute buffering to the ocean cannot keep pace with the rate of anthropogenic CO2 increase,” added Waldbusser, who is in Oregon State’s College of Earth, Ocean, and Atmospheric Sciences. “As long as the saturation state is high, the oysters and mussels we tested could tolerate CO2 concentrations almost 10 times what they are today.”
The idea that early bivalve development and growth is not as physiologically linked to CO2 or pH levels as previously thought initially seems positive. However, the reverse is actually true, Waldbusser noted. Larval oysters and mussels are so sensitive to the saturation state (which is lowered by increasing CO2) that the threshold for danger will be crossed “decades to centuries” ahead of when CO2 increases (and pH decreases) alone would pose a threat to these bivalve larvae.Learn more

Oregon: The Coast is a new interactive, multimedia application that’s part of Oregon State University’s Beaver Nation campaign, aiming to document how OSU people and programs connect with the state, the nation – and the world beyond. And it features Sea Grant Extension agent Ruby Moon in a feature about buying fresh seafood off the docks from the people who catch it.
“I was nervous,” says Moon, who worked with David Baker of OSU’s Interactive Communications unit this summer to produce her segment. “But they made me look smart.”
Moon works out of the Lincoln County Extension office in Newport on issues related to fisheries, seafood and marine renewable energy.
