2012 marked the 10th year of BGOS & JWACS/JOIS collaborations on expeditions to the Beaufort Gyre onboard the CCGS Louis St. Laurent. Bill Williams was again the Chief Scientist on the cruise, which occupied all of August and the first week of September. IOS and collaborators again acquired hydrographic and geochemical stations, the 3 BG moorings were again recovered, refurbished and redeployed, and 4 ITPs were deployed -- some with IMBs, AOFBs, O-buoys, and other automated measuring devices. In addition, 2 new mooring systems were deployed west of the BGOS array in collaboration with the National Institute of Polar Research (NIPR) and Tokyo University of Marine Science and Technology (TUMSAT) in Japan, and a JAMSTEC shallow water mooring on the Chukchi Abyssal Plain was recovered.
