Vertical migration is a geographically and taxonomically widespread behaviour among
zooplankton that spans across diel and seasonal timescales. The shorter‐term diel vertical …

The western subarctic gyre (WSG) and the eastern Alaska Grye (AG) on each side of the
subarctic North Pacific, have many similarities. In both gyres, macronutrients are generally …

Marine zooplankton must deal with seasonal variations of the upper-ocean environment that
are both intense and prolonged compared to their life spans. This leads to large seasonal …

Sockeye salmon (Oncorhynchus nerka) populations from Southeast Alaska through British
Columbia to Washington State have experienced similar declines in productivity over the …

The allocation of resources between growth, storage, and reproduction is a key trade-off in
the life-history strategies of organisms. A central dichotomy is between capital breeders and …

To evaluate the impacts of ontogenetically (seasonally) migrating copepods on carbon
transport to the mesopelagic zone, we investigated depth distribution, population structure …

A recent drastic decrease in sea ice cover area was observed in the western Arctic Ocean
during summer, yet little information is available for its effect on zooplankton community. To …

Lipid‐fuelled overwintering by copepods can be a regionally important contribution to
carbon sequestration in the deep oceans. Here, we estimate the contribution for Calanus …

Abstract The North Pacific Ocean subtropical–subarctic gyre transition region is recognized
as an important small pelagic fish nursery and feeding ground. To clarify the lower trophic …

Biomass distribution and trophodynamics in the oceanic ecosystem in the Oyashio region
are presented and analyzed, combining the seasonal data for plankton and micronekton …
