Abstract
2016 IBRV Araon Arctic Cruise Leg-2, Expedition ARA07C was a highly multidisciplinary undertaking carried out in the East Siberian Sea (ESS) on the IBRV Araon from August 25 to September 10, 2016 (Figure S1). The program was conducted as a collaboration between the Korea Polar Research Institute (KOPRI), P.P. Shirshov Institute of Oceanology (IORAS), and Alfred Wegener Institute (AWI). Multiple research experiments were carried out to investigate seafloor processes and methane release related to the degrading sub-sea permafrost, gas hydrate, and seismostratigraphy in the upper slope and shelf area of the ESS. In addition, physical and chemical oceanography measurements in the water column were undertaken with linked atmospheric studies from the vessel. The expedition focused on two main research areas: the upper slope and shelf areas in the ESS from August 27 to September 4 and the western slope of the Chukchi Plateau from September 6 to 8.
