CSIDE preliminary results presented at the IBWC Citizen’s Forum
CSIDE graduate student Derek Grimes and co-PI Sarah Giddings attended and presented at the International Boundary & Water Commission Citizen’s Forum on 1 September 2016. Grimes showed preliminary results from the CSIDE project which was highlighted in the local news.
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. We pumped 30 gallons of dye into the Mouth of the Tijuana River Estuary on an ebbing tide over 2 hours. Rob was leading the dye release and here he is at the estuary mouth as dye is flowing: We … Read More
Dye Release 2: 8-9 Oct 2015
We released dye just north of the IB pier in the early morning hours of October 8th and tracked the dye for 2 days. The dye shot northward in response to a strong southerly swell driving strong northward currents. At first it was confined to the surfzone, after which it was confined to an alongshore band just outside of the surfzone. … Read More

Dye Release 1: 23-24 Sept 2015
We have successfully concluded our first dye release experiment. The preliminary observations are promising, as we have comprehensive measurements of what turned out to be a spectacularly dynamic behavior. The raw standalone fluorometer data is substantive. The figure below illustrates the alongshore extent of the dye plume within the surf-zone. Thank you, to the numerous agencies that made these … Read More
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!
Dog Collar Drifters
This GPS dog collar system is typically used by hunters (among others) to follow their furry friends on the hunt. We have customized them to help us track the dye overnight, when boat, jet ski and airplane operations are suspended. Four drifters (smurf, snork, bugs, and daffy) will be deployed on the periphery of the dye plume before dark, and … Read More
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:
