November 2012 GoMRI-III sampling cruise: macroalgae and macrocrustaceans offshore Ewing Bank
This video shows the box dredging leg of the November 16-17, 2012 sampling cruise offshore the northwestern Gulf of Mexico, Stations 5-7 at Ewing Bank (~28o05.146 #39;N, 91o01.66 #39;W) at depths between 54-79 m. The cruise is the field component of the grant "Genetics of the Macondo Oil Spill on Coastal Ecosystems" awarded to Darryl Felder and Suzanne Fredericq from the University of Louisiana at Lafayette, funded by the Gulf of Mexico Research Initiative (GoMRI-1) through the Louisiana University Marine Consortium grant "The Effects of the Macondo Oil Spill on Coastal Ecosystems" Nancy Rabalais, PI. The goal of the research is a critical assessment of post-Deepwater Horizon oil pill impacts on the diversity, vitality, and distribution of offshore benthic seaweeds and macrocrustaceans (and associated fauna) in the NW Gulf of Mexico. The Hourglass-design box dredge provides a now standardized method of semi-quantitative sampling. It is an effective tool only on substrata of low relief that consist of loose rocks and rubble, shells or shell hash, and calcareous nodules (rhodoliths). The expedition departed from LUMCON in Cocodrie LA, on board the R/V Pelican, a 32 m (105ft) ABS Class "A-1+ Oceanographic, steel-hull coastal research vessel operated by UNOLS. Filming and editing by S. Fredericq.
