Cruise Code MR04-K02 :: Main Research Theme Time-series observational study on the Material Cycle in the North Pacific :: Objectives The northern North Pacific, especially its western part, has been attracting attention of chemical oceanographers because of its importance in global biogeochemical cycles of carbon and its related materials, which have a great impact on the climate change of the earth. In addition, physical oceanographers have been interested in that region with respect to the formation of the North Pacific Intermediate Water. Despite its importance, there has been few systematic survey and time-series observation of biogeochemical processes in the area to estimate the impact of high latitude seas on the global climate change. :: Outline of Observation Based on the above mentioned goal, time-series observational stations including station K1 (51N, 165E), K2 (47N, 160E) and K3 (40N, 160E) (tentative) were set. During cruise, time-series observational mooring systems will be recovered and deployed. In addition, seawater, aerosol, suspended materials and plankton will be collected. Vertical profiles of salinity and temperature will be measured by XBT and XCTD. :: 5. Main Research Area The northwestern North Pacific including the above stations ::
