Temperature, salinity, microplankton abundance and other data from three cruises of the R/V Cape Hatteras in the NW Atlantic to study bacterial activity, August 2001 - March 2002 (NCEI Accession 0001675)

This data is from three cruises on the R/V Cape Hatteras taken in Aug and October 2001, and March 2002 from Boothbay Harbor Maine to the Sargasso Sea. The purpose of these cruises was to study single-cell bacterial activity using the CTC assay (Sieracki et al. 1999) in context with other microplankton parameters. Onboard flow cytometry (B-D FACScan instrument) was used to count pico- and nanoplankton, including total bacteria and CTC-active bacteria. Pico- and nanophytoplankton were measured live (no sample preservation). CTD data is reported here along with the pico- and nanoplankton abundances. The CTD data is from the bottle trip depths only. The SeaBird CTD was provided by the ship. At stations a drifting drogue, marking the water at 15m, was deployed and the CTD vertical profiles were taken at the drogue.
