This project will produce a novel oceanographic data base of the Eastern Bering Sea spanning the years 1987 – present. Imagery from multiple satellite sensors will be used to characterize the region’s sea surface temperature, suspended sediment and plankton patterns at 1km spatial resolution on daily, weekly and monthly frequencies. Specialized algorithms will be applied to AVHRR visible data to bridge the important ocean color data gap existing between 1987 and late 1997 when no dedicated ocean color sensor was available. The time series will be analyzed for pattern changes, anomalies and trends, and these data will be correlated to salmon abundance measurements, on both basin-wide and watershed-specific spatial scales.
1) To compile a satellite image-based environmental data base of the eastern Bering Sea spring-fall season spanning 1987 to 2003 (16 years) including daily (when possible), weekly and monthly SST fields at 1km spatial resolution, and weekly and monthly chlorophyll concentrations at 1km. Additionally, regional variability, anomalies and other relevant statistics will be computed. This entire data base will be made available to all interested persons on CD-ROM with its own integrated viewing and analysis software, and/or through a future AYK-SSI data web site. 2) Obtain salmon catch, return and other abundance records for the AYK watersheds and utilize the above data series to perform initial analyses of spatial environmental variability and salmon abundance. This will be done to evaluate the potential impact/importance of the remotely sensed variables on salmon declines in the AYK region (and to help guide future research priorities). Emphasis will be placed on separately evaluating effects on the various watersheds to investigate possible differences in their salmon populations’ response to the environmental conditions (which could help fine-tune regional management).
