Title: Chlorophyll data from bottles, buckets, and ice from RVIB Nathaniel B. Palmer cruises NBP0103, NBP0104, NBP0202, and NBP0204 in the Southern Ocean from 2001-2002 (SOGLOBEC project) (NCEI Accession 0112394)
Abstract: This dataset contains biological data collected on RVIB Nathaniel B. Palmer during cruises NBP0103, NBP0104, NBP0202, 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, depth, and total phaeopigment. The instruments used to collect these data include Turner Designs Fluorometer -10-AU. These data were collected by Dr Maria Vernet of University of California-San Diego 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.

Chlorophyll data from bottles, buckets and ice

Dataset Description:
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.

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
