Russian EEZ planned work
During each cruise, research will be carried out in two parts. First, we will use a towed, undulating instrument platform to make continuous underway hydrological and bio-optical measurements of the upper 350 m of the ocean. We will tow the platform in 'radiator' grid patterns to resolve three-dimensional variability. We are specifically interested in the subpolar front, which resides primarily in the Russian economic zone. The front moves back and forth (northward and southward) with time, so our surveys may occasionally extend into Japanese waters for brief periods before returning to the Russian economic zone (please see charts in Appendix B). We will use a shipboard Acoustic Doppler Current Profiler to measure water velocity and a variety of meteorological instruments (listed separately) to make boundary layer atmospheric measurements as well. In addition to the towed measurements, we plan to execute a series of hydrochemical profiling stations using a Seabird profiler, a 24-bottle rosette and a bio-optical profiling package. These stations will be made along the same lines previously sampled using the towed profiler and are meant to provide detailed resolution across the subpolar front. The hydrochemical stations allow us to take water samples for measuring nutrient levels, dissolved oxygen and bio-optical parameters. Cold, dry air outbreaks from the Eurasian landmass dominate wintertime forcing over the Japan/East Sea. To observe the spatial structure of this forcing and its oceanic response we would also like to make several longer north-south sections with the towed platform. These additional sections would take place only during the winter 2000 cruise. We respectfully request permission to make scientific measurements within the Russian economic zone, south of 41¡ 15Õ N during the periods between approximately 21 May 1999 to 31 May 1999 and between approximately 13 January 2000 to 3 February 2000.
