Nutrient concentrations and primary production in the Bering Sea in June 1992

Calculations of new production (NP) are made based on hydrochemical characteristics, recycling production (RP) is assessed on the basis of recycling of phosphorus and nitrogen. Photosynthesis, coupling with uptake of nutrients and development of minimum of silicate and maximum of oxygen, at the lower chlorophyll maximum in the pycnocline is discussed. In situ determination of production by C-14 and oxygen and vertical scanning of chlorophyll A have permitted to calculate assimilation numbers for all the biohydrochemical areas and to map primary production (PP) distribution in the Bering Sea. The total PP in the Bering Sea has been assessed as 6.4x10**8 t C/yr.

Oceanographic Data of the 37th Japanese Antarctic Research Expedition from November 1995 to March 1996

The results of oceanographic observations on board the icebreaker "Shirase" and tidal observations at Syowa Station, Antarctica, are presented in this report. The oceanographic observations were carried out by the summer party of the 37th Japanese Antarctic Research Expedition (JARE-37) during the austral summer of 1995/1996. The tidal observations were carried out by the winter party of JARE-36 from February 1995 to January 1996.
