Abstract:

Hydrographic data were collected during cruise OC468 using a CTD-rosette system aboard the R/V Oceanus. Our objectives were to collect water column and benthic 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.
