Vargas uses St. Jones lab to investigate blue carbon with support from NSF CAREER Award

The world’s coastal ecosystems — areas such as tidal marshes and mangrove forests — have the potential to store and sequester large amounts of carbon, collectively known as blue carbon. Former President Barack Obama in 2014 made research on understanding carbon dynamics in these coastal ecosystems a priority because of their importance to the global carbon cycle.

Despite their role as potential sinks – or storehouses – of carbon, it is still unclear how different biophysical processes influence carbon dynamics in these ecosystems.

Using funds from his recently awarded National Science Foundation Faculty Early Career Development Award, the University of Delaware’s Rodrigo Vargas will establish an outdoor laboratory at the St. Jones Reserve, which is a component of the Delaware National Estuarine Research Reserve (DNERR) and part of the National Estuarine Research Reserves (NERR). His research efforts will contribute to a better understanding of vertical and lateral carbon fluxes — the amount of carbon exchanged between the land and the atmosphere, and the amount of carbon exchanged between the land and the coastal ocean — in tidal coastal wetlands.

Through the prestigious NSF Career Award, Vargas, associate professor in the Department of Plant and Soil Sciences in UD’s College of Agriculture and Natural Resources (CANR), also will work to empower minority students by integrating them into research, educational and outreach activities, and will enhance social capital by strengthening the network of students, science professionals and researchers in salt marshes across Delaware and beyond.
