Nutrient regeneration and oxygen consumption after a spring bloom in Funka Bay were studied on monthly survey cruises from February to November 1998 and from March to December 1999. A high concentration of ammonium (more than 4 µmol l−1) was obser

The chemical and biological conditions, and the bacteria-heterotrophic nanoflagellate (HNF) relationship were investigated in the vicinity of Funka Bay, southwest of Hokkaido, Japan during early spring 1999. At the time of sampling, chlorophyll a con

We studied the temporal variations of bacterial abundance and production in subarctic Funka Bay (Hokkaido, Japan) for a 1 yr period, and related this data to chlorophyll a (chl a) concen- tration (highest conc. = 5.9 µg l -1 ), particulate organic c

Time-series sediment traps were deployed for "ve consecutive years in two distinctively di!erent subarctic marine environments. The centrally located subarctic pelagic Station SA (493N, 1743W; water depth 5406 m) was simultaneously studied along with

The numbers of heterotrophic bacteria in the subarctic coastal seawater of Funka Bay, Japan, were mea- sured by flow cytometry, and 2 different bacterial assem- blages were detected: cells with low DNA content (Group I) and cells with high DNA conten

Time series observations over 36 h were carried out in Funka Bay, Japan, to complement a 6 yr nutrient-dynamics study during a diatom spring bloom, especially focusing on nitrate and silicate as limiting nutrients. At the beginning of the study, nutr

Phytoplankton samples were collected during spring bloom of diatoms from three coastal areas of Japan using a NORPAC P-25 net (25-micron opening) with a NGG52 prenet (335-micron opening), and 25 major and trace elements have been analyzed by INAA. Co

Fluxes of amino acids and hexosamines were determined using time-series sediment trap samples collected at 3200 m in the Bering Sea (Station AB; 53°30′N, 177°00′W) and at the 4400 m in the central subarctic Pacific (Station SA; 49°00′N, 174

The seasonal changes of nitrogen metabolism in the sporophyte of Laminaria japonica (Phae-ophyceae) were investigated under a natural environment. The experiment was conventionally distinguished by concentrations of nitrogen compounds dissolved in se
