Page 1 has six plots per page in the following format.

Panel 1 : True Wind Speed (m/s)
Panel 2 : True Wind Direction (compass degrees, relative to true North); convention is oceanographic (e.g., winds blowing TO; 180 = winds blowing FROM North TO South)
Panel 3 : Latitude (degrees)
Panel 4 : Longitude (degrees; East is positive; West is Negative)
Panel 5 : Atmospheric Pressure (mb)
Panel 6 : Air Temperature (deg Celsius)

Page 2 has six plots per page in the following format.

Panel 1 : Long Wave Radiation (W/m2)
Panel 2 : Short Wave Radiation (W/m2)
Panel 3 : Relative Humidity (%)
Panel 4 : Sea Surface Temperature (deg Celsius) from two independent sensors
Panel 5 : Surface Salinity (psu)
Panel 6 : Fluorescence (volts)

Notes:
a) sample logging onboard done at 15 second intervals
b) data are plotted at 15 second intervals
c) True Wind Speed and Direction and Fluorescence also have overplotted a 3 minute average. Because there was significant loss of data (particularly, position info) in the data stream, the averaging was done for a 3 minute interval centered on the observed data point. Thus, the number of points in the average may range from 1 (no averaging) to 12 (all observations from a 3 minute window good). Fluorescence sensor was extremely noisy. Averaging of Wind data done to minimize effects of high frequency ship motion from record.
