Description

Chlorophyll and phaeopigment concentrations from near-surface profiles collected using the conventional CTD in the Southern Drake Passage and Antarctic Peninsular region on cruise NBP 16-08.

Methods & Sampling

Triplicate samples of 100-200 mL were filtered onto 25 mm GFF filters and extracted using the protocol of:
Jespersen, A.M. and Christoffersen, K. (1987) Measurements of Chlorophyll-a from phytoplankton using ethanol as extraction solvent. Arch. Hydrobiol. 109 (3) 445-454, as updated in:
Morison, F. and Menden-Deuer, S. (2015) Early spring phytoplankton dynamics in the sub polar North Atlantic: The influence of protistan herbivory. Limnol. Oceanogr. 60(4) 1298-1313.

Analyses were performed by Ms. Zuzanna Abdala (ODU) and Ms. Alexa Sterling (URI).

At the start of the cruise, Turner 10-AU Fluorometer was calibrated using Chla Standard Stock Solution (SSS) from Anacystis nidulans algae (#C-5753) following the protocol by Kirk Ireson & Karen Baker (PDF).

Calibration was performed by Dr. Randelle Bundy (UW) and Dr. Bethany Jenkins (URI).

Data Processing Description

BCO-DMO Processing:
- changed date format from m/dd/yyyy to yyyy-mm-dd;
- changed time format to HH:MM (some were originally H:MM);
- added underscore in platform column, replacing the space;
- added ISO_DateTime column.
