The field trip for Biological Oceanography today was on the research vessel Questuary. We left from Ft. Baker right at the north tower of the Golden Gate Bridge. We headed west out the gate just past Kirby Cove to deploy a CTD (conductivity, temperature, depth) sensor. These sensors measure...you guessed it conductivity (~salinity), temp, and depth. Nice software to plots ctd in realtime as it sinks.
