NODC Accession 0112394 includes profile, discrete sample and biological data collected aboard the NATHANIEL B. PALMER during cruises NBP0103, NBP0104, NBP0202 and NBP0204 in the South Atlantic Ocean and South Pacific Ocean from 2001-04-29 to 2002-09-12. These data include CHLOROPHYLL A and PHAEOPIGMENTS. The instruments used to collect these data include fluorometer. These data were collected by Maria Vernet of University of California-San Diego as part of Southern Ocean GLOBEC. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NODC on 2013-07-24. The following is the text of the abstract provided by BCO-DMO: Chlorophyll a and Phaeo Pigments from Bottle Casts and Ice / Ice Cores A short note on the "Southern Ocean Grid System": The grid is a Cartesian plane covering the sample region in which distances are easy to calculate. The grid system used for SOGLOBEC is a universal transverse mercator (UTM) projection with a certain base point and rotation. The base point was chosen in the far south and the rotation was chosen to create one axis along the peninsula, and the other offshore. The units of UTM are meters, but the points are chosen in km rounded to the nearest km. Negative numbers mean that samples were taken southwest of the y axis or southeast of the x axis. For more details see: Complete explanation of the Southern Ocean grid system. (http://globec.whoi.edu/so-dir/soglobec.grid.txt) METHODS: Chlorophylls were dissolved in 90% acetone and measured using a Turner Designs Digital 10-AU-05 Fluorometer. The instrument was calibrated using chlorophyll a standards from Sigma Chemicals as noted below. Calibration Notes: NBP0103 Calibrated at start of cruise using Sigma Chemicals chl_a standard. Calibration values used were as follows: High Fd: 0.109 High tau: 1.970 Med Fd: 0.111 Med tau: 1.950 Low Fd: 0.109 Low tau: 2.215 Calibration Notes: NBP0104 Calibrated at start of cruise using Sigma Chemicals chl_a standard. Calibration values used were as follows: High Fd: 0.090 High tau: 1.982 Med Fd: 0.092 Med tau: 1.981 Low Fd: 0.100 Low tau: 2.215 Calibration Notes: NBP0202 Calibrated at start of cruise using Sigma Chemicals chl_a standard. Calibration values used were as follows: High Fd: 0.109 High tau: 1.954 Med Fd: 0.103 Med tau: 1.949 Low Fd: 0.100 Low tau: 1.954 Calibration Notes: NBP0204 Calibrated at start of cruise using Sigma Chemicals chl_a standard. Calibration values used were as follows: High Fd: 0.149 High tau: 1.887 Med Fd: 0.141 Med tau: 1.968 Low Fd: 0.149 Low tau: 1.938 Data submitted by: Maria Vernet Scripps Institute of Oceanography University of California, San Diego La Jolla, California 92093-0218 Phone: 1-858-534-5322 email: mvernet@ucsd.edu (mailto=mvernet@ucsd.edu) Last update: November 30, 2005; gfh
