|Hydrographic Stations in the Bering Sea|
what we did are as follows,
Faculty of Fisheries, Hokkaido University
|Monitoring of marine ecosystem in the Eastern Bering Sea Shelf|
the mass of cold bottom water has decreased.
And the Oshoro-maru dataset revealed temprature of the "cold bottom water", which is generated during ice freezing period, has increased (3-4oC) since 2002.
But we could identify the cold bottom water over the middle shelf and the inner shelf (Left figure, less than 1~2oC).
our result in this year suggests that ice production increased during previous winter.
|The Observation of Boundary Currents (the BSC and ANSC)|
|We observed the Bering Slope CUrrent (BSC) and Aleutian North Slope Current (ANSC) using the ADCP and CTD (Upper figure, station 151 - 164). We can estimate the transports of ANSC, BSC and on-shelf flow at the shelf break.|
