Data Needs for Modeling(6)
- Hydrographic
-
-
- Salinity values as affected by fresh-water ice melt in spring (if ice is not modeled explicitly)
-
-
- Heat fluxes; global datasets can yield semi-reasonable values
-
-
- Currents
-
- Boundary conditions and fluxes are needed to drive the physical model and/or verify output at Bering Sea entrances and exits.
-
-
- Possible assimilation of current meter data.
-
-
- Drifter data would help fill out mesoscale detail for larval transport models.
-
-
- Satellite
-
- Ocean color and altimetry for possible data assimilation.
-
-
- Coastal Observations
-
- Coastal runoff - not too significant
-
-
- Atmosphere
-
- Insolation
-
-
- Winds - FNOC winds at 2.5 degree resolution supplemented with buoy and ship data from the middle and outer shelf (after May).
-
-
- Meteorological data on front passage for spring bloom timing. Meteorological stations available at: St. Paul, Adak (soon to close), Cold Bay, King Salmon, Unalaska, Bethel, Pt. Moeller, Cape Newenham.
-
-
- For decadal scale simulations, long-term series exist for air temperature, and climatic indices such as the PNA and the Southern Oscillation Index
-
-
- Primary and Secondary Production
-
- Possible assimilation of chlorophyll data from satellites and biophysical platforms.
-
-
- Zooplankton data for assimilation/calibration of NPZ models.
-
-
- Boundary conditions for NPZ.
-
-
- Fisheries
-
- Appropriate environmental indices need to be determined for input to statistical models to predict fish stocks. Hindcasts and process-oriented simulations may help suggest appropriate indices.
-
-
- Spatial patterns of predation for spatially explicit models of lower trophic levels.
