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

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

MCIP Fabrication

Our fabrication guru, Kent Smith, welds components for the mobile cart instrument platforms (MCIP). Assembly is now complete, and the steel frames are at San Diego Galvanizing to be galvanized–this treatment prevents corrosion and will extend the lives of these units. Each cart will be outfitted with instruments to measure temperature, pressure, dye concentration, and water velocity. Our volunteers will … Read More

Dye Pump Calibration

  Here, Rob Grenzeback and Derek Grimes are grinding away calibrating the dye pump.  We need to know exactly how much dye gets metered out for our experiments and so calibrating the pump is extremely important.   This is a very pink task!      

dye ski testing!

Rob Grenzeback climbing down the Scripps Institution of Oceanography’s pier ladder to conduct the first tests of the Dye Ski! The Dye Ski being hoisted down to the water to meet Rob is a jet ski that is configured to measure the dye concentration, turbidity, and temperature of the water! During our experiments, it will run transects from the surfzone offshore over … Read More
