Particle and zooplankton sample elemental (C,N) and isotopic (13C, 15N) data, Cruise EN509, northern Gulf of Mexico, May 26 - June 19, 2012

Particle and zooplankton samples were collected during cruise EN509 using a CTD-rosette and a MOCNESS aboard the R/V Endeavor. Our objectives were to characterize the physical and chemical properties in the water column at ECOGIG seep and other study sites. The ship departed Gulfport MS on for cruise EN509 on 05/25/2012 and collected samples at ECOGIG and other sites before returning to Gulfport on 06/20/2012.
