PRIMARY PRODUCTIVITY and PHOTOSYNTHETIC ACTIVE RADIATION (PAR) site samples data collected in the South Atlantic Ocean and South Pacific Ocean on the NATHANIEL B. PALMER cruises NBP0103, NBP0104 and others as part of the Southern Ocean GLOBEC project from 2001-04-29 to 2002-09-12 (NODC Accession 01

NODC Accession 0112168 includes discrete sample, site samples, biological and physical 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 PRIMARY PRODUCTIVITY and PHOTOSYNTHETIC ACTIVE RADIATION (PAR). The instruments used to collect these data include CTD, radiometer and PAR Sensor. 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 2013-07-31.

The following is the text of the abstract provided by BCO-DMO:

Simulated in Situ Primary Production Data
Data Notes:
1..Cruise NBP0104. A total of only 6 SIS experiments were completed, due to freezing of the deck incubator. Ref: cruise report.
2..PAR measurements. PAR was measured with a Biospherical Instruments GUV Radiometer (cosine-corrected downwelled irradiance) mounted on ship's science mast configured with PAR channels (400-700nm). PAR values are intergated over the duration of the in situ experiment. Ref: cruise reports

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 deatails see: Complete explanation of the Southern Ocean grid system. (http://globec.whoi.edu/so-dir/soglobec.grid.txt)
