- Objectives and Brief Narrative of Cruise
The aims of the cruise are to study (1) the variability of the deep ocean circulation flow (current meter and CTD mooring), (2) the distribution of the deep water mass in the western North Pacific (CTD with water sampling and lowered ADCP), (3) the vorticity distribution in the Kuroshio Extension (shipboard ADCP and XCTD), (4) the advection and dissipation processes of the subtropical mode water (CTD with water sampling, lowered ADCP, shipboard ADCP, and XCTD), (5) the physical/chemical/biological processes of the system of the subtropical mode water and seasonal pycnocline (CTD with water sampling, XCTD, and fast repetition rate fluorometer), (6) estimating vertical turbulent diffusivity with observing density ratio and energy dissipation ratio (CTD with water sampling, XCTD, and turbulence-microstructure acquisition profiler), (7) the ocean circulation with ARGO floats, and (8) the distribution and ecology of floating seaweeds and sessile organisms in the northwest Pacific.
