He was a pioneer in this area of archaeology in the United States, starting with the wrecks of the schooner Neptune and those within the Golden Gate National Recreation Area . [ 5 ]
[21] [22] Collaborative research between the UCDWR and the Navy led to the discovery of the deep scattering layer, a region from 300 - 500 m deep filled with organisms. [23] The UCDWR would continue to research sound beacons and sonar until being absorbed into the Navy Electronics Laboratory and Scripps Marine Physical Laboratory between 1945 ...
During the four-year voyage, he assisted in the research of the oceans including collecting marine samples, making and noting observations, and making improvements to marine instrumentation.
