The USGS and the University of Maryland’s Chesapeake Biological Laboratory conducted a study in the Chesapeake Bay to quantify greenhouse gas fluxes from the largest estuary in the U.S.

Geoffrey DeBenedetto (USGS Arizona Water Science Center) and Jin-Si Over (USGS Woods Hole Coastal and Marine Science Center) set up a GNSS base station to enable geodetic corrections of the UAS flight trajectory and ground survey data at Great Sippewissett Marsh in Falmouth, Massachusetts as part of a multiday, small uncrewed aircraft system (sUAS) lidar training.&n
