The IMR zooplankton database holds Barents Sea data on species composition (abundance), size fractionated biomass as well as biomass for particular zooplankton groups obtained from standard seasonal transects (Fugløya-Bjørnøya and Vardø-Nord) and a regional coverage of the Barents Sea during autumn. Data on species composition are limited.

The dataset holds data on eggs and larvae from fish species collected during 4 surveys along the Norwegian coast Stad - Lofoten during spring 1987.

The IMR zooplankton database holds Norwegian Sea data on size fractionated biomass as well as biomass for particular zooplankton groups obtained from standard seasonal transects (Svinøy, Gimsøy and Bjørnøya-vest) and a regional coverage of the Norwegian Sea during spring. Data on species composition (abundance) are limited.

Abundance and distribution of capelin larvae were investigated using a Gulf III plankton sampler on surveys conducted in May-June in the southern Barents Sea. The time series started in 1981 and lasted until 2006, when the survey series was discontinued.

Abundance and distribution of herring larvae are investigated using Gulf III and T-80 plankton samplers on surveys conducted in March/April along the Norwegian coast.

The dataset contains juvenile fish (postlarvae) from the Barents Sea sampled during June-July 1977-91 (1980-91 in database, 1977-79 on files).

The IMR zooplankton database holds North Sea data on species composition (abundance), size fractionated biomass as well as biomass for particular zooplankton groups obtained from standard seasonal transects (Utsira-StartPoint, Feie-Shetland, Hanstholm-Aberdeen, Torungen-Hirtshals) and a regional coverage of the northern North Sea and Skagerrak during April-May. Data on species composition are limited.

The Macroplankton dataset in the IMR plankton database contains macroplankton from the Norwegian and Barents Seas. The dataset includes small vertically migratory fish.

The dataset contains sampling of red king crab for a long period. The data has been sampled with trawl and traps, and the sampling has been conducted mostly during the autumn.

Dataset collating kelp occurrences (presences and absences) from surveys conducted across the Azores archipelago (NE Atlantic) using remotely operated vehicles, drop-down cameras, open and closed-circuit SCUBA diving, and fisheries by-catch information.
