Arctic Collaborative Ecosystem SKQ2023-12S Cruise Report

The NOAA Distributed Biological Observatory (DBO)/Ecosystems & Fisheries Oceanography Coordinated Investigations (EcoFOCI) joint cruise with the Arctic Marine Biodiversity Observation Network (AMBON) and the Chukchi Ecosystem Observatory (CEO) programs included hydrographic and biological surveys consisting of conductivity-temperature-depth (CTD) rosette sampling, zooplankton and larval fish net tows, Van Veen grabs and HAPS coring for sediment sampling, and beam trawling for epibenthic collections. The cruise conducted recoveries and deployments of year-round marine mammal listening moorings and oceanographic moorings (Figure 1.1, 1.2). The goal of the cruise was to evaluate ecosystem status and change in the northern Bering and Chukchi Seas.
