This dataset includes biological, chemical, current measurements, navigational, optical, physical, profile, and underway data collected aboard the USCGC Healy during cruise HLY21TD in the Arctic Ocean, Baffin Bay and others from 2021-08-25 to 2021-09-13. These data include Attenuation/Transmission, CONDUCTIVITY, CURRENT SPEED - EAST/WEST COMPONENT (U), CURRENT SPEED - NORTH/SOUTH COMPONENT (V), Chromophoric Dissolved Organic Matter (CDOM), DEPTH - BOTTOM, DEPTH - OBSERVATION, DISSOLVED OXYGEN, FLUORESCENCE, HYDROSTATIC PRESSURE, LATITUDE, LONGITUDE, PHOTOSYNTHETIC ACTIVE RADIATION (PAR), SALINITY, WATER TEMPERATURE, course over ground, and speed over ground. The instruments used to collect these data include ADCP, CTD, GPS, PAR Sensor, bathythermograph - XBT, echo sounder, fluorometer, oxygen sensor, and transmissometer. These data were collected by United States Coast Guard as part of NWP MSR transit. The Rolling Deck to Repository (R2R) program submitted these data to NCEI.

The CTD data submitted by the originator represent the raw data suite. The ADCP data represent the raw dataset. Post processed quality assessed data are not available in this dataset. R2R provides a processed version of the CTD data. A suite of navigation products produced by R2R is included in this dataset, comprised of one high resolution, one 1 minute resolution, and one low resolution coordinate file.
