CSIDE – aerosols!

Members of the UCSD/SIO Prather aerosol team joined our project looking for dye in the air… so far the results are VERY exciting! The red box in the pictures below sucks in a bunch of air condensing all of the air-borne water droplets into a sample.

Release #3 – at the mouth of the Tijuana River Estuary

Our 3rd dye release was 12 October and we sampled through 13 October. It was the most ambitous release yet.

Tijuana Estuary instrument checks

We have been checking on the instruments in the Tijuana Estuary weekly as they become entangled in kelp and covered in mud quickly!

ADCP tests

On September 17th, we tested out some of our boat-based instrumentation which is used to sample currents, salinity, temperature, and dye in transects offshore. Some pictures from those tests are here:

REMUS tests

REMUS – Remote Environmental Monitoring UnitS is an autonomous underwater vehicle that swims in a pre-programmed mission to sample the water currents, salinity, temperature, and dye concentration. Here you can see us testing out REMUS the week before our first dye release on September 16th! Things did not quite go as planned as you can see…
