The first cruise for marine science started as one of projects under the Japanese Antarctic Research Expedition (JARE) from the year 43rd party. The Research Vessel Tangaroa (National Institute of Water and Atmospheric Research, NIWA, 2282 ton) was chartered for the cruise. This cruise was one of the time-serial observations shared by RMV Aurora Australis (Australian National Antarctic Research Expedition) in October-December 2001, RV Hakuho Maru (Ocean Research Institute, University of Tokyo) in January 2002, and icebreaker Shirase (JARE-43) in March. The RV Tangaroa departed from Port of Hobart (Tasmania, Australia) on 6th of February 2002. She cruised to the target area (>61°S along 140°E), conducting continuous observations (surface temperature, salinity and fluorescence, ADCP, XCTD/XBT, acoustic, continuous plankton recorder, air sampling). Station observations started from 0000 13th February (local time) from the southernmost station (Station 8, 66°26'S, 140°00'E). The transect observation between Stations 8 and 1 (61°S, 140°E) finished at 0821 24th February. During the transect observation, two moorings, which were deployed using Shirase in March 2001 (JARE-42) and RV Hakuho Maru in January 2002, were successfully recovered. Almost all observation items, including three times deployments and recoveries of drifting buoys, were performed. After the transect observation, the surface water observations were conducted again between 61°-66°26'S along 140°E. Station observations were conducted at several points, which were observed by RMV Aurora Australis and RV Hakuho Maru. All of the station observations were finished by 1305 2nd of March 2002, and RV Tangaroa returned to Port of Hobart at 0800 7th of March.
