As a result, researchers are able to reach areas with depths greater than 1000 meters in less than an hour by boat from the facility.

MLML operates two vessels, the 56-foot (17 m) R/V John H. Martin, and the 30-foot (9.1 m) R/V Sheila B. Moss Landing Marine Laboratories participates in the Sea Grant Colleges program by hosting an office of the UC Sea Grant Extension Program, affiliated with University of California, San Diego.
