A Firm Grip

Marine technician Gary Austin of the Scripps Institution of Oceanography’s Marine Physical Laboratory assembles a soft tether release on the Low Frequency Acoustic Seismic Experiment (LFASE)  in August 1989. Researchers from Scripps and WHOI including marine geophysicist Ralph Stephen sailed on the R/V Melville that summer to deploy seismometers and other instruments that could detect Earth’s ambient “noise” with a seafloor borehole array seismic system (SEABASS).
