Bacterioplankton Secondary Production Estimates for Coastal Waters of British Columbia, Antarctica, and California
The principal objective of this study was to quantify the rate of heterotrophic bacterioplankton production. Production was estimated by two approaches: (i) measurement of increasing bacterial abundance with time in filtered (3-μm pore size) seawater and (ii) estimation of bacterial deoxyribonucleic...
