The Ocean Archive System searches our original datasets as they were submitted to us, not individual points or profiles. If you want to search and retrieve ocean profiles in a common format, or objectively analyzed fields, your better option may be to use one of our project applications. See: Access Data

| 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. The following is the text of the dataset description provided by BCO-DMO: 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. Calibration Values Southern Ocean GLOBEC II - Nathaniel B. Palmer 01-04 Notes: Performed serial dilution calibration at start of cruise using Sigma Chemicals chl_a standard.
