Underway chlorophyll data from RVIB Nathaniel B. Palmer and ARSV Laurence M. Gould cruises NBP0104, LMG0203, and NBP0204 in the Southern Ocean from 2001-2002 (SOGLOBEC project)
Methods:
Surface chlorophyll samples were collected from the ship's flow-through seawater system, which has seawater intakes between 5 and 7 meter depths on both ships. About one liter of seawater was vacuum filtered onto GF/F filters and passively extracted in 7 ml of 90% acetone at -20deg C in the dark for at least 24 hours. Chlorophyll fluorescence was then measured on a Turner Design Digital 10-AU-05 fluorometer calibrated prior to the cruise.

Notes:
Performed serial dilution calibration at start of cruise using Sigma Chemicals chl_a standard.
The following are the calibration values:
