JGOFS Japan related Projects

The following is a list of some of JGOFS Japan related Projects.

North Pacific Process Study of JGOFS Japan

Eastern Tropical Pacific (Hakuho Maru Cruise KH-90-2)

The objectives of the Hakuho Maru KH-90-2 Cruise (Sep.3-Oct.25,1990) were to study the biological productivity, biogeochemical circulation of nitrogen and carbon, and the biogeography and vertical migration of zoo plankton and micronekton and to compare these data with previous data in order to obtain a better understanding of the long-term variation in the Equatorial Pacific Ecosystem.

Part of the Preliminary Report of this cruise is available here as the pdf file.

Northwest Pacific Carbon Cycle Study (NOPACCS; 1990-1996)

The New Energy and Industrial Technology Development Organization (NEDO) launched in the fiscal year 1990 its industrial technology research and development project on global environment under the financial and other assistance of the Ministry of International Trade and Industry (MITI). As part of this project, Northwest Pacific Carbon Cycle Study (NOPACCS) was commenced in 1990 for a period of seven years.
NOPACCS data will be available at JODC soon.

Ocean Fluxes: their Role in the Geosphere and Biosphere (1991-1993)

This project funded by the Ministry of Education, Science and Culture from 1991-1993, and was organized into four major area; 1) Flux of terrestrial materials to the ocean, 2) Biological production and export flux of particulate matter, 3) Flux of materials at the tectonically active bottom of the sea, 4) Ocean circulation and its effect on material flux in the ocean.

WOCE Hydrographic Programme (1991-)

Many Japanese research organizations have participated in this programme.

• Japanese WHP One Time Surveys
• Japanese WHP Repeat Lines

Biological Production and Biochemical Cycles in the Coastal Areas

This project funded by the Ministry of Education was aimed at assessing the primary productivity of the Sagami Bay as well as to assess the organic carbon flux from the continental shelf area to the open sea in the Sagami Bay trough. A third objective was to develop a biophilic element cycling model to explain the phytoplankton-zooplankton-bacterial interaction in the coastal waters of the Ozuchi Bay.

Marginal Sea Flux Experiment (MASFLEX; 1992-1997)

This project was a joint China-Japan study in the East China Sea and was funded by the Science and Technology Agency, Japan from 1992 to 1997. The purpose of MASFLEX was to understand processes of the flux of carbon and other biogenic elements in the marginal seas as this area afforded an ideal environment for examining the behavior of nutrients and suspended matter on the shelf and the slope as well as between the shelf and the Kuroshio Current which flows northwards and eventually into the adjacent Pacific Ocean.
MASFLEX data will be available from JODC on April 1999 after a 2 year period.

Ships of opportunity measurements of pCO2 in the northern North Pacific (1995-)

A joint study of the Japanese Institute of Environmental Sciences and Canadian Institute of Ocean Sciences, it aims to understand the temporal variability of sea surface pCO2 in the northern north Pacific.

SubArcyic Gyre Experiment (SAGE;1997-)

This project has been funded by the Science and Technology Agency, Japan from 1997 to date.
The objectives of this project are as follows:

• to observe the structure and variability of the North Pacific subartic gyre system.
• to examine the behavior of carbon dioxide in the subarctic circulation system.
• to investigate the interaction between the subarctic and the subtropical gyre.
• to develop a high resolution prognostic model and an inverse model for the North Pacific.

Assessment of the environmental effect of deep water CO2 dumping

An approved 5 - year programme supported by the National Institute for Resources and Environment, Ministry of International Trade and Industry, Japan in order to examine the behavior and environmental impact of CO2 dumped into the 1000 m layer of the northwestern North Pacific. It is a post - NOPACCS project.

Time series observations at a station in the western subartic Pacific

This is to examine the long term temporal changes in material cycling processes in the western subarctic Pacific including those changes associated with biological processes regulating.
