NASA has awarded $134,000 to SMAST Dean Steven Lohrenz to lead a multi-institutional study of CO2 exchange along continental margins. The project will use linked terrestrial and coastal models, along with ship and satellite observations, to address the significant uncertainties in coastal carbon fluxes, which are in turn a source of uncertainty in predictions of ocean acidification and climate change. The team will also establish “geospatial portals,” map-based sites to allow the wider research community to access data based on location. The project will be jointly conducted with partners at universities in Alabama, Georgia, Mississippi and North Carolina, and will focus on the Mississippi River watershed, northern Gulf of Mexico, and southeastern U.S. coast.
