NOTE: Longitudes are expressed in 0-360 E-W longitude

Drogue off date of 1-1-79 indicates we were unable to interpret the drogue
status from the drogue sensor readings.

Drogue off date equal to start time means drogue was off since deployment

Drogue off date equal to ending time, buoy ended with its drogue attached.

Drogue off date equal 0 0 0 indicates drogue still attached and buoy is alive
