Optimizing Ocean Acidification Observations for Model Parameterization in the Coupled Slope Water System of the U.S. Northeast Large Marine Ecosystem

Grace Saba, Rutgers University

The U.S. Northeast Shelf Large Marine Ecosystem, supports some of the nation’s most economically valuable coastal fisheries, yet most of this revenue comes from shellfish that are sensitive to ocean acidification (OA). Furthermore, the weakly buffered northern region of this area is expected to have greater susceptibility to OA. Existing OA observations in the NES do not sample at the time, space, and depth scales needed to capture the physical, biological, and chemical processes occurring in this dynamic coastal shelf region. Specific to inorganic carbon and OA, the data available in the region has not been leveraged to conduct a comprehensive regional-scale analysis that would increase the ability to understand and model seasonal-scale, spatial-scale, and subsurface carbonate chemistry dynamics, variability, and drivers in the NES. This project optimizes the NES OA observation network encompassing the Mid-Atlantic and Gulf of Maine regions by adding seasonal deployments of underwater gliders equipped with transformative, newly developed and tested deep ISFET-based pH sensors and additional sensors (measuring temperature, salinity for total alkalinity and aragonite saturation [ΩArag] estimation, oxygen, and chlorophyll), optimizing existing regional sampling to enhance carbonate chemistry measurements in several key locations, and compiling and integrating existing OA assets. The researchers will apply these data to an existing NES ocean ecosystem/biogeochemical (BGC) model that resolves carbonate chemistry and its variability.

Postdoctoral Fellow in Chemical Oceanography

University of Delaware

The University of Delaware (UD) College of Earth, Ocean, and Environment is seeking applications for a Postdoctoral Research Scientist position in chemical oceanography and metrology. The successful candidate will work on a NOAA funded project to aid in the development of a reference material for ocean pH by establishing traceability of pH indicator dyes to the International System of Units (SI). The scholar will make use of state-of-the-art analytical and experimental facilities at the National Institute of Standards and Technology (NIST) in Gaithersburg, Maryland. Candidates must have a PhD in either chemical oceanography, analytical chemistry, or a closely related field. Demonstrated skills with spectrophotometry, potentiometry, nuclear magnetic resonance spectroscopy, and/or physical chemistry are preferred. The position will be located at the NIST facility in Gaithersburg, MD, but the appointment will be made through the University of Delaware. The postdoc will also attend field test cruises with the UD group. The appointment will be for one year, with continuation pending funding and progress.

Please contact Wei-Jun Cai (wcai@udel.edu) and Regina Easley (regina.easley@nist.gov) for additional information.

Mid-Atlantic Ocean Acidification Graduate Fellowship Opportunity

Ocean Acidification Program and Sea Grant

The Mid-Atlantic Sea Grant Programs in partnership with the NOAA Ocean Acidification Program, are pleased to announce the availability of Ocean Acidification Graduate Research Fellowships for a two-year period covering the 2018 and 2019 academic years. The fellowship is open to full-time graduate students at any academic institution in Delaware, Maryland, New Jersey, New York and Virginia who are engaged in coastal and marine research relevant to regional ocean, coastal, and estuarine acidification. The focus should be on improving understanding of the potential ecological consequences of increasing carbon dioxide concentration in regional coastal waters. Projects may encompass natural and/or social science research topics.

Proposals are being accepted through 5:00 pm ET on Friday, April 13, 2018 via [EasyDNNnewsLink|91].  

This announcement and additional information can be found on each state Sea Grant program’s website.
