Water temperature, salinity, and others taken by CTD and other instruments from the research vessel Araon in the Chukchi, Bering Seas, and north Pacific from 2021-07-20 to 2021-07-24 (NCEI Accession 0250487)

These datasets were collected during the research vessel Araon cruise 12, 2nd Leg (ARA12B) in summer of 2021 and submitted by Kyoung-Ho Cho from the Korea Polar Research Institute (KOPRI), who was the chief scientist of the ARA12B cruise. There are several categories: physical, chemical, biological, meteorological, and underway. Physical dataset includes CTD and Lowered ADCP measurements. Chemical dataset includes nutrients, DIC, and total alkalinity (TA). Biological dataset includes Chl-a (concentration and size fraction), pigment, zooplankton abundance, microzooplankton abundance, bacterial abundance, and photochemical efficiency of phytoplankton. Meteorological dataset includes air temperature, relative humidity, air pressure, wind, shortwave/longwave radiations, and radiosonde observations. Underway data include pCO2, black carbon concentration, and inherent optical properties. Meteo and underway were collected quasi-continuously during the entire cruise, cover larger area, and have longer time span. This cruise is U.S. State Department MSR U2021-010 as part of the World Data Service for Oceanography. Data are in CSV and text formats.
