Field Activity 2012-016-FA

Identifier 2012-016-FA
Alternate names RC89; Chesapeake Bay 0612
Purpose Measure greenhouse gas fluxes from the upper, lower and middle portions of the Chesapeake Bay. Work will be conducted aboard the R/V Rachel Carson in collaboration with scientists from the University of Maryland's Chesapeake Bay Laboratory.
Location Chesapeake Bay, United States, North America, North Atlantic;, Greenhouse Gas Flux Measurements
Summary From June 18-June 22, 25 km+ of surface methane and CO2 data collected in the lower, mid and upper chesapeake Bay. Vertical profiles of the methane and CO2 concentration and d13C also obtained at 5 sample stations using a submersible pump to supply the equilibrator
