Arctic squid

Micromesistius poutassou is a pelagic gadiform fish that feeds on zooplankton and small nekton in the North Atlantic.

Calanus finmarchicus is a small calanoid copepod that drifts through the water column of the North Atlantic.

In Norwegian Current food webs, Atlantic cod can also operate as a higher-level predator when it feeds on forage fish and large pelagic invertebrates.

Clupea harengus, the Atlantic herring, is a schooling pelagic fish that feeds on zooplankton in surface and near-surface waters.

Mallotus villosus, the capelin, is a small schooling forage fish that feeds on plankton and small crustaceans.

Skeletonema marinoi is a small diatom that forms chains of cells in nutrient-rich coastal and shelf waters.

The Norwegian Current carries Atlantic water north along the Norwegian coast toward the Barents Sea and Arctic gateway. Spring blooms of diatoms and coccolithophores feed copepods, krill, fish, seabirds, seals, and whales. Because it links the North Atlantic to polar seas, it is a strong example of how circulation shapes subpolar food webs and ocean climate.
