| Session Description | Studies on ocean carbon cycles have been progressed markedly since 1990s. Global ocean carbon monitoring systems started with coarse-grid resolution and semi-decadal frequency (WOCE), but now it has grown up to have far higher spatio-temporal resolution by integrating vast amount of short-track carbon measurement data occupied by each nation. For pCO2, the Surface Ocean CO2 Atlas project (SOCAT : http://www.socat.info/ ) have collected over 7.5 million quality-checked pCO2 data to produce 1o x1o gridded pCO2 field in the world open oceans with no temporal and spatial interpolation. Now efforts are also being directed to integration of coastal and marginal sea measurements, with five SOCAT coastal regional group established along the coast / marginal sea areas of Indian and western Pacific Oceans. For water column carbon data, the "Carbon dioxide in the Atlantic Ocean" data synthesis project (CARINA) have corrected data from over 15000 stations, mostly from Atlantic and southern Oceans, while the "Pacific ocean interior carbon" data synthesis project (PACIFICA: http://cdiac.ornl.gov/oceans/PACIFICA/ ) is now obtaining over 6000 stations of water column carbon data from North and South Pacific. The PACIFICA effort is now extending to include the data from coastal and marginal seas in North and South Pacific region, as same direction as the present effort of SOCAT coastal regional groups. This session welcome all presentations related to ocean carbon studies in the Pacific, Indian Ocean and their marginal seas, aiming towards integrations of these carbon data The present lack of regional / temporal coverage and required international cooperation will also be discussed. |
