The overall goal of this study is to obtain a quantitative description of the water mass composition, kinematics, and dynamics of the Atlantic water boundary current in the eastern Arctic Ocean over an annual cycle, in order to elucidate the role of the current in regulating the Arctic system. The project is part of a larger cooperative program entitled the Atlantic Water Inflow Experiment (ATWAIN), which is an international collaboration between six institutions: The Woods Hole Oceanographic Institution (WHOI), USA; the Institute for Marine Research in Bergen, Norway (IMR); the Norwegian Polar Institute (NPI); the University of Svalbard (UNIS); the University of Tromsø (UT); and the Institute of Oceanology Polish Academy of Sciences (IOPAS). The main goal of ATWAIN is to better understand how the Atlantic water spreads into the Arctic Ocean, including the manner in which it interacts with the pack-ice and how it is transformed within the Eurasian Basin. As part of our study, six moorings were deployed across the Atlantic water boundary current near 30E for a one-year period, from September 2012 to September 2013. WHOI provided the four offshore moorings in the array.
