The Epsilometer and the biological hotspots ...

In April 2018, a team of Scripps graduate students designed a 3 days experiment on the R/V Sproul in order to explore a biological hotspot south of San Clemente Island, only a few miles west of San Diego. This area is known to support large populations of demersal and pelagic fish, such as rockfish and tuna. While both the scientific and local fisheries communities are well aware of such biological productivity, little is known about the physical mechanisms that aid the high productivity at this site. The students proposed to investigate the flow in order to test several hypotheses and determine the physical mechanism that drives the elevated biological productivity.

In addition to the Del Mar mooring recovery and deployment of a WireWalker, the students tested new sensors developed by Scripps physical oceanographers Matthew Alford and Arnaud Le Boyer. Dubbed the epsilometer or “epsi,” the device uses advances in electronics borrowed from the cell phone industry to measure water turbulence (epsilon) in a low-cost, low-power manner. 🎥: Isabela Le Bras

Marine Physical Laboratory interns rock it this summer!

MPL interns Eli Simmons, Louise Xu and Drew Vagen have been hard at work in our lab this summer.  Among their many accomplishments: creation of a new travel-time acoustic current meter (Louise), calculation of the flow through the Samoan Passage from a high-resolution model (Drew), and design and construction of many new mechanical devices (Eli).  Thanks to all of you for your talent and hard work this summer!  Since Louise is a UCSD student, we're happy that she'll continue with us this fall.
