PHOTOSYNTHETIC ACTIVE RADIATION (PAR) profile data collected in the North Atlantic Ocean on the ENDEAVOR cruises EN259, EN262 and others as part of the GB project from 1995-01-12 to 1995-06-04 (NODC Accession 0106520)

NODC Accession 0106520 includes profile and physical data collected aboard the ENDEAVOR during cruises EN259, EN262, EN264, EN266 and EN267I in the North Atlantic Ocean from 1995-01-12 to 1995-06-04. These data include PHOTOSYNTHETIC ACTIVE RADIATION (PAR). The instruments used to collect these data include radiometer and PAR Sensor. These data were collected by Jeff Van Keuren of Woods Hole Oceanographic Institution as part of GB. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NODC on 2013-04-25.

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

Photosynthetically Available Radiation

Most information regarding individual profiles is provided with the individual data files (location, correction to GMT, light units, sensor type and characteristics, date of latest calibration).
Upcast and downcast profiles sorted separately by depth, then time. Downcast listed first. Raw values listed - no averaging.
All profiles were taken with the same two (Biospherical Instruments, Inc. San Diego, CA) instruments: underwater unit (PUV-500) and matched deck unit (PUV-510). Last Calibration of Sensors: 15 DEC 95.
The December 1995 recalibration results have been applied to all readings. The change in calibrations from the previous April 1993 factory measurements were less than 2%.
All profiles were taken from same location on the R/V Endeavor: starboard side using the J-frame. Whenever sea condition allowed, the ship was turned such that the sun was shining on the starboard side and as close to amidship as possible.
