Seawater conductivity refers to the ability of seawater to conduct electricity. The presence of ions in the seawater, such as salt, increases the electrical conducting ability of seawater. As such, conductivity can be used as a proxy for determining the quantity of salt in a sample of seawater. This is the unprocessed data that are output directly from the sensor which are then converted to salinity in S m-1.
Dissolved Oxygen (DO) Concentration from the Fast Response (Fastrep) Dissolved Oxygen Instrument is a measure of the concentration of gaseous oxygen mixed in seawater. This Instrument measures dissolved oxygen concentrations on shallow coastal profilers through rapid oxygen gradients. This data product is corrected for salinity, temperature, and depth from a collocated CTD.
