This Ain’t No Pleasure Cruise

Craig Marquette (in yellow) and Glen Gawarkiewicz prepare to deploy the conductivity-temperature-depth (CTD) rosette for hydrography studies north of Cape Hatteras in January 2005. The winter cruise on the research vessel Oceanus took researchers to “the graveyard of the Atlantic” for studies of the dynamic currents flowing in the region where the warm and salty Gulf Stream breaks away from the coast and turns toward Europe while converging with the “shelfbreak jet,” a strong current at the edge of the continental shelf that carries cold, relatively fresh water from the Arctic and North Atlantic Oceans.
