Particle and zooplankton sample elemental (C, N) and isotopic (13C, 15N) data from Cruise OC468, Louisiana, Mississippi, Alabama Self Break, August and September, 2010

Samples were collected during cruise OC468 using a CTD-rosette, a MOCNESS, and ring nets aboard the R/V Oceanus. Our objectives were to collect water particle and zooplankton samples in the Northern Gulf of Mexico immediately following the Deepwater Horizon incident. This cruise was funded by the Biological Oceanography Program at NSF and was repurposed to explore the impacts of the spill and to provide a platform for investigators with rapid response funding from NSF. The ship departed Gulfport MS on 08/21/2010 and collected samples at sites near the wellhead as well as to the south and southwest of the wellhead before returning to Gulfport on 09/16/2010.
