Compilation of Calanus glacialis and Calanus hyperboreus abundance data, Arctic Ocean, 1934-2016

This dataset contains Calanus glacialis and Calanus hyperboreus abundance data compiled January 2017-September 2018 for the study Kvile KØ, Ashjian C and Ji R. 2019: Pan-Arctic depth distribution of diapausing Calanus copepods. Biological Bulletin 237, DOI: 10.1086/704694. Data span from 1934 to 2016 and cover the entire Arctic Ocean and surrounding subarctic seas. See DataSources_Kvile2019_BiolBull.xlsx for a full overview of data sources. Specifically, the dataset includes stage-specific abundance data for Calanus glacialis and Calanus hyperboreus copepodid stages (C1-C5) and adults (C6 male or female) given as ind. m-3 (counts per cubic meter) or ind. m-2 (counts per square meter). Data of merged stages (e.g. C1-C3) or of other units (biomass, presence/absence etc.) were not included. Data missing information about sampling date, location (longitude, latitude), depth (upper and lower depth of sample), gear or mesh size were not included. Some data are depth-integrated (surface-bottom), while other are for specific depth layers with multiple layers per station.
