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…
visit to Playas de Tijuana
On September 15th, Falk and Sarah drove down to Tijuana to check out the release location on Playas de Tijuana and meet with our amazing collaborator Margarita Diaz at the Proyecto Fronterizo de Educaciòn Ambiental A.C.. Here you see Falk and Margarita talking on the beach. It just started raining when we were on the beach, the rain turned into a large … Read More
MCIP training
September 9, 11, and 12th we completed several more MCIP training sessions for volunteers, undergraduates, and lifeguards. Everyone had a blast!
Tijuana Estuary deployments!
Early September, we deployed instruments in the Tijuana Estuary so that we could monitor if the estuary received any dye from the coast.
CSIDE MX Dye release simulation!
Below is a movie of a MX dye release similar to the other rleases that Nirnimesh has put together. The dye release location here is at the very southern part of Playas Tijuana, where we will be doing our dye release. Again, Nirnimesh is simulating the week from 9/30-10/7 2014 for moderate waves from 200 deg south, similar to … Read More
CSIDE US/MX border dye release simulation
Nirnimesh has completed another round of dye release simulations to help us prepare for the upcoming dye releases. For this release Nirnimesh is simulating the week from 9/30-10/7 2014 for moderate waves from 200 deg south. The movie lasts for a week. The first dye release lasts 2 hours and the 2nd release lasts 6 hrs. In this case … Read More
ADCP boat mount for the Sally Ann
Kent and the SIO machine shop have fabricated a sweet ADCP mount for the Sally Ann. This will enable tracer flux calculations from the coupled ADCP and towed aray measurements. Kent got it done on Friday and did the first test mount Friday late afternoon up at Seaweed Canyon. Pretty awesome.
First Test of MCIP carts
On Wed 26 August, we had the first full field test of the MCIP carts which went really well. A MCIP cart stands for Mobile Cart Instrumentation Platform. An instrumented MCIP is shown in the first picture of the gallery below. It is basically a steel wheelbarrow that can roll into the surfzone. It has a range of instrumentation, including an … Read More
Moored current-meter setup
On Monday and tuesday August 24-25, we prepared moored current meters for deployment. This included installing battery packs, calibrating their compasses, performing instrument checks, preparing the frames they will sit on, and preliminary programming amongst other things. In these pictures, you see acoustic current meters, specifically Acoustic Doppler Current Profilers (ADCP), which using the Doppler shift to measure the water currents … Read More
New pre-experiment CSIDE dye release simulations: comparing 2hr and 6 hr releases
In the previous post we presented the first dye simulation that Nirnimesh has done. That simulation was for a release that totalled 2 hrs. Now, Nirnimesh has performed an identical experiment for dye released for 6 hrs and compared the two. The modeling details are the same: This is with the COAWST model that couples waves and currents and has … Read More
