The Arctic Nearshore Impact Monitoring in Development Area III (ANIMIDA III) Project was designed to update previous evaluations of impacts that may have resulted from offshore oil and gas exploration and production in the coastal Beaufort Sea. The Bureau of Ocean Energy Management (BOEM), Alaska Outer Continental Shelf (OCS) Region previously sponsored the following three major environmental monitoring programs in the Development Area: (1) the Beaufort Sea Monitoring Program (BSMP, 1984–1989), (2) the ANIMIDA Project (1999–2002), and (3) the continuation of the Arctic Nearshore Impact Monitoring in the Drilling Area (cANIMIDA) Project (2004–2007). As part of this four-year ANIMIDA III, Olgoonik Fairweather (OF), in conjunction with a team of scientists, conducted two seasons of offshore in open water and one season of spring sampling field collection in ice programs. A team of scientists from the University of Alaska-Fairbanks (UAF), The University of Texas at Austin (UTA), Florida Institute of Technology (FIT), Battelle Memorial Institute (Battelle), Kinnetic Laboratories Inc. (KLI), and OF comprise the project team.
