Satellite-Derived Chl-a, POC, SST, PARand River Discharge Seasonal Climatology

for the Georgia Bight

Sergio Signorini and Chuck McClain

• SeaWiFS-derived Chl-a (OC4v4), POC (D. Clark), and PAR (R. Frouin)• NOAA CoastWatch AVHRR SST• Seasonal climatology based on period from September 1997 to August 2004 • GAB is divided into 8 regions:

• GAB North (30.5oN < Lat < 33.0oN) and South (28.5oN < Lat < 30.5oN)• Inner Shelf (0-20m), Middle Shelf (20-40m), Outer Shelf (40-60m), and

Slope (60-500m)

• Three-month composites of Chl-a, POC, PAR, and SST for the SAB• Seasonal time series from monthly climatological composites of Chl-a, POC, PAR, and SST for each of the 8 GAB regional domains• Seasonal outflow climatology for 3 major rivers discharging into GAB
