Introduction

HLY1901 station locations

The third annual of research cruise the Distributed Biological Observatory – Northern Chukchi Integrated Study (DBO-NCIS) took place on the US Coast Guard Cutter Healy, from 4–23 August, 2019. The overall goal of DBO-NCIS is to document and understand ongoing changes to the Pacific-Arctic ecosystem in light of the changing physical drivers. The main objectives for the cruise were (1) to occupy key transects on the northern Bering and Chukchi shelves, including DBO lines 1-5, with an extensive suite of water column and benthic measurements; (2) to carry out a high-resolution survey of the Chukchi Slope Current to shed light on its fate; (3) to collect numerous underway measurements of the atmosphere-ocean-ice system; and (4) to service moorings owned by the Japan Agency of Marine Science and Technology (JAMSTEC). In addition to the core components of the DBO-NCIS program, a number of ancillary projects were added which enhanced the breadth of the scientific measurements conducted during the cruise.
