  8. Japan / East Sea JES 3 Jan/ Feb 2000 Cold Upwelling Eddy SeaSoar Cruise track and Station Locations Wasm front East Korean Warm Current

  9. Jan 18, 2000 Feb 2, 2000 Japan Japan Korea Korea 16 14 Semi- Persistence Eddies occurred at the Subpolar From from the Beginning to End of Cruise Jan 18 – Feb, 2. Examples of the Frontal Location are Shown with the ship track and station locations 12 11 6 5

  10. SeaWiFS derived • K532 • Diffuse • Attenuation • Coefficient • Bio-optical properties • Show eddy structure • Along the coast. The optical properties in cooler (North) and warmer (South) have similar bio-optical properties.

  11. SeaWiFs Chlorophyll (SeaBAM ) Jan 21, 2000 0339z - Chlorophyll ~ 0.6 – 1.5 mg/ l clouds Feb 1, 2000 0330z clouds These chlorophyll imageries show the response of the surface biology to the passage of a 2 cold front.

  12. Western Extension Central Extension East Extension Sea surface temperature imagery were composted for a 2 week period to define the SST climatology. Three extensions of the warm Tsumia current are illustrated which penetrate the basin interior.

  13. Surface attenuation coefficient Ship track of the surface Optical properties B A B front A Front AVHRR- SST Surface Absorption Surface optical properties changes at the Subpolar Front, decreasing in the colder waters.

  14. AVHRR – SST for Jan 28, 2000 Illustrating the passage of a cold front the extension of the warm Tsumina current at the Yamato Rise.
