Definition Numerical representation of UTC day and fraction of a day in Matlab format time, UTC string in yyyymmddHHMMSS format Latitude of measurements collected by Furuno GPS. Longitude of measurements collected by Furuno GPS. Latitude of measurements collected by Ashtech GPS. Longitude of measurements collected by Ashtech GPS. Logical flag identifying availability of differential correction Vessel coarse over ground in degrees true Vessel speed over ground in nautical miles per hour Vessel heading in degrees true measured by ships gyroscope Wind direction relative to ship measured from starboard anemometer Wind speed relative to ship measured by starboard anemometer True wind direction corrected for ships heading from starboard anemometer True wind speed corrected for ships speed and heading measured by starboard anemometer Wind direction relative to ship measured from port anemometer Wind speed relative to ship measured by port anemometer True wind direction corrected for ships heading from port anemometer True wind speed corrected for ships speed and heading measured by port anemometer Air temperature as measured by ships sensor Atmospheric pressure measured by ships sensor Relative humidity measured by ships sensors. Solar radiation Photosynthetically Available Radiation at the water surface voltage from Eppley PIR pyrgeometer thermopile raw value from Eppley PIR Pyrgeometer thermopile flux calculated from the Eppley PIR Pyrgeometer thermopile Sea surface temperature from ships flow through pumped system Sea surface conductivity from ships flow through pumped system Salinity measured from sensors in ships flow through pumped system uncalibrated estimate of chl concentration from flow through pumped system Transmissometer (volt) for diagnostic purposes Calculated from transmission according to: Beam attenuation coefficient c = - ( 1 / (path length[m]) * ln ( light transmission [decimal] ) from ships flow through pumped system voltage from Satlantic In-Situ Ultraviolet Spectrophotometer, nitrate nitrate measured with Satlantic In-Situ Ultraviolet Spectrophotometer Accuracy = 2uM or 10%
