Environmental data collected along the track of NBP 10-02 to the W Ant. Peninsula

These data include temperature of the water and air, salinity, relative humidity, PAR, wind direction and speed, barometric pressure, fluorometry and short- and long-wave radiation collected at 1 minute intervals. These data are part of the suite of measurements from the ship collected by Raytheon Polar Services, the ship operators of the Research Vessel Ice Breaker (RVIB) Nathaniel B. Palmer, distributed on CD to the departing Chief Scientist.This along track (JGOFS) data set was obtained primarily by applying calibrations to raw data and decimating to whole minute intervals.

Several fields are derived measurements from more than an single raw input. For example, Course Made Good (cmg) and Speed Over Ground (sog) are calculated from gyro and GPS inputs. Cruises often used '9.99' or '9999' or NaN to indicate bad or missing data.
