CTD-O2 = Conductivity Temperature Depth - Oxygen



This is an SBE Seacat profiler 19plus, made by Seabird Electronics, Inc. of Bellevue, WA, a company that got its research start right here at the Applied Physics Lab at the University of Washington.

It measures:
Temperature using a digital thermistor
Salinity using a conductivity probe (saltier water conducts electricity better than fresher water)
Depth using a barometer (every 10 m of water depth equals an additional atmosphere of pressure)

We also have a new sensor to measure:
Dissolved oxygen using a membrane technology (fish need O2 to breathe)
