The 2018 cruise was conducted aboard the Research Vessel Akademik Tryoshnikov (AT) in August - September, 2018 as part of the Nansen and Amundsen Basins Observational System II (NABOS-II) project. A total of 126 stations were occupied during the main cruise, including 134 separate CTD casts. Stations were split between three primary groups: NABOS, Changing Arctic Transpolar System (CATS), and Trans-Arctic Ice (TICE). Stations occupied by the CATS group included AT18-001 through AT18-026, AT18-051 and AT18-052, where “AT18-” stands for Akademik Tryoshnikov 2018. The TICE group (stations AT18-082 through AT18-088, AT18-090, AT18-101) was primarily concerned with the deployment of autonomous sensor suites on (or in) pack ice. A total of 92 hydrographic stations were occupied by the NABOS group during the cruise, including AT18-028 through AT18-050 and AT18-054 through AT18-126, minus the intermittent ice stations. At all but 6 of these stations, water samples were collected for a variety of chemical and ...
