Title: 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) (NCEI Accession 0112638)
Abstract: This dataset contains biological data collected on ARSV Laurence M. Gould and RVIB Nathaniel B. Palmer during cruises LMG0203, NBP0104, and NBP0204 in the South Atlantic Ocean, South Pacific Ocean, and Southern Ocean from 2001-01-01 to 2002-12-31. These data include chlorophyll a and total phaeopigment. The instruments used to collect these data include Turner Designs Fluorometer -10-AU. These data were collected by Dr Kendra L. Daly of University of South Florida as part of the "U.S. GLOBEC Southern Ocean (SOGLOBEC)" project and "U.S. GLOBal ocean ECosystems dynamics (U.S. GLOBEC)" program. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2023-01-23.

Underway chlorophyll data

Dataset Description:
Underway Chloro and Phaeo Pigments,
Hull Intake Sampling

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.
