IMIS

Zooplankton collections were made to investigate spatial distribution, species and stage composition of the zooplankton in the central and MIZ of the Barents Sea. Vertical tows from bottom to surface were done with a WP-2 net (0.5 m2 mouth area, 180 µm mesh) at 7 stations in March 1998, 2 stations in May 1998, and 10 stations in July 1999. Sampling stations were geo-referenced with a GPS using decimal latitude and longitude with 2 decimals. This resulted into a digital database with 508 rows and 18 species. The ship was R/V Jan Mayen. Total zooplankton abundance and biomass in the Atlantic waters of the Barents Sea were dominated by Calanus finmarchicus, the Arctic waters – by Calanus glacialis.
