Temperature, salinity, microplankton abundance and other data from three cruises of R/V Cape Hatteras in the NW Atlantic to study bacterial activity, 2001-08 to 2002-03 (NCEI Accession 0001675)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: October 03, 2025 | Last Modified: 2004-08-23T00:00:00.000+00:00
This data is from three cruises on 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.
