Year-to-year changes of the Alaskan Stream surface flow, forming the northern boundary of the western subarctic
cyclonic gyre in the Pacific, impact the dynamics of water in the eastern Okhotsk Sea. It is shown by Lagrangian
simulation of transport of the Alaskan Stream waters in 20 year-long AVISO velocity field and direct computation
of the corresponding fluxes that an intensification/weakening of the Alaskan Stream current leads to increased/
decreased northward fluxes in the areas of the Krusenstern and Fourth Kuril straits connected the Okhotsk Sea
with the Pacific Ocean. Enhancement of the Alaskan Stream flux is accompanied by an increase in water temperature
and decreasing ice area in the Okhotsk Sea in winter. The Alaskan Stream surface flux is shown to be negatively
correlated with satellite-derived chlorophyll-a concentration in May from r = −0.68 to −0.73 in
1998–2013 and with winter–spring biomass of large-sized zooplankton with r = −0.70 in 1995–2012. It is positively
correlated with winter–spring biomass of small- and medium-sized zooplankton in the eastern Okhotsk
Sea with r = 0.74 in 1995–2012
