The Oyashio shelf region and the seasonally ice-covered areas north of Hokkaido are highly
productive, supporting a wide range of species including marine mammals, seabirds and …

Nutrients and plankton dynamics were investigated in the Oyashio region of the western
subarctic Pacific. Observations were carried out between 1990 and 1998 along A-line, which …

Life cycles of large suspension-feeding copepods were investigated in the western subarctic
gyre (Oyashio area). Two populations were recognized in Neocalanus flemingeri by body …

The ontogenetic vertical migration and life cycle of Neocalanus plumchrus were investigated
by anal-yzing monthly population structure at Site H in the Oyashio region from September …

Seasonal, ontogenetic and bathymetric variations of diet were examined for walleye pollock
Theragra chalcogramma based on a total of 6666 fish collected off the southeastern coast of …

Organic carbon (C) and total nitrogen (N) contents and corresponding isotope ratios were
determined in surficial sediment (0–3 cm) at 94 stations ranging from 21 to 1995 m water …

Coastal oceans interacting with terrestrial ecosystems play an important role in
biogeochemical cycles. It is therefore essential to research land–ocean interactions for …

The phytoplankton community in the western subarctic Pacific (WSP) is composed mostly of
pico-and nanophytoplankton. Chlorophyll a (Chl a) in the< 2 μm size fraction accounted for …

To illustrate areal differences in the structure of lower trophic levels of the pelagic
ecosystems in the subarctic Pacific, data collected in the quasi-steady state summer/fall …

Life cycles of the large suspension‐feeding copepods, Eucalanus bungii and Neocalanus
cristatus were investigated by seasonal sampling in the western subarctic Pacific. Eucalanus …
