DATA: (headers include sensors and units)
- sci_m_present_time: time (GMT) in seconds since Jan 1 1970
- drv_sciwater_pressure: pressure in decibars, equals depth of measurement in meters
- drv_latitude: latitude, degrees N
- drv_longitude: longitude, degrees E
- drv_sea_water_temperature_cor: corrected temperature in degrees celsius
- drv_sea_water_salinity_cor: corrected salinity in PSU
- drv_sea_water_density_cor: corrected density in kilogram per meter cubed
- drv_sci_oxy3835_wphase_oxygen_cor: corrected dissolved oxygen concentration
- drv_sci_oxy3835_wphase_mass_cor: corrected dissolved oxygen concentration (direct conversion from drv_sci_oxy3835_wphase_oxygen_cor to get to milligram per liter/parts per million)
