Understanding carbon cycling in coastal habitats is critical for understanding global carbon budgets and opportunities for climate change mitigation. At the interface between oceanic and terrestrial environments, blue carbon systems, such as salt marshes, sequester large amounts of carbon via productivity and sedimentation. A factor that can offset this carbon sequestration is the outwelling of carbon to adjacent ecosystems. MIT Sea Grant created three environmental sensing buoys that continuously measure vital coastal parameters including temperature, salinity, chlorophyll fluorescence, CDOM (Colored Dissolved Organic Matter) fluorescence, optical backscatter, wind speed and direction, light (as photosynthetically active radiation), air temperature, and relative humidity. Using data from those buoys and 12 years of transect data they were able to estimate the total outwelling of dissolved organic carbon (DOC) using high-resolution in situ chromophoric dissolved organic matter (CDOM) as a proxy for the Neponset Salt Marsh in Boston, Massachusetts.
Virginia Sea Grant Launches the USDA and NOAA-Supported Aquaculture Information Exchange Online Community Platform
The Aquaculture Information Exchange (AIE) online community platform website is now live and open for new user registrations. The AIE represents a joint effort between NOAA’s National Sea Grant Office, NOAA’s Fisheries Office of Aquaculture, USDA’s Agricultural Research Service (ARS), USDA’s National Institute of Food and Agriculture (NIFA), and Virginia Sea Grant.
