As an undergrad math major at UCSD winter quarter 1993, Kris Beard had a student assistant job, helping Sandy Tacoma working to support Professor Harmon Craig of SIO, Scripps Institution of Oceanography, in the Isotope Laboratory, in the basement of Ritter Hall. obits

In December 2023, I met Ed Slater at the Encinitas Senior Center Computer Lab.

I volunteer Wed 9:30-11a each week to help seniors using the lab PC computers and wifi network or their own notebook computers they may bring in. Ed was there Thurs 21Dec working with Lambert Ling, the other "tutor". We started talking and eventually realized we knew each other from Harmon Craig's Isotope Lab at SIO. Ed was a marine tech who went to sea on the R/V Melville as part of the GEOSECS program. ScrCap from the movie "Rivers of the Sea: The GEOSECS story", link below.

I found a GREAT video from NSF posted on YouTube providing an overview of GEOSECS with interviews of actual participants.

ABS - This proposal is to make helium measurements on the World Ocean Circulation Experiment (WOCE) cruises in the central Pacific on longitude 150 west. The helium data are useful as tracers of the deep ocean circulation, particularly in regions near the east Pacific rise from which elemental helium is known to emanate. These measurements, along with hydrographic and other tracer measurements will form the basis for ocean circulation descriptions and models which are the principal objectives of WOCE.
