Chlorophyll and Primary Production [Lomas/BIOS]

These data were collected from process stations and other stations where the Photoplankton Ecology Laboratory group collected bulk chlorophyll (Chl) measurements on the following Bering Sea Ecosystem Study-Bering Sea Integrated Ecosystem Research Program (BEST-BSIERP) cruises: HLY08-02, HLY08-03, HLY09-02 and Knorr 195-10. BEST-BSIERP together are the Bering Sea project. Data presented are total and >5um Chla, and total and >5um primary production.

All samples were collected on the eastern Bering Sea shelf from 55-63N and 164-180W during spring and summer. At process stations, seven (7) depths were sampled representing roughly the 100%, 55%, 30%, 17%, 9%, 5% and 1.5% light depths. At other stations, generally four (4) depths were sampled and were chosen as surface, deep chlorophyll maximum, and two other depths selected based upon equal distributions throughout the water column or profile features (e.g., elevated concentrations near the bottom).
