Photographs of the sea floor provided some of the first clues about the abundance of life in the deep ocean, lava flows on the mid-ocean ridge crest, and evidence for hydrothermal venting.
The WHOI-MISO Facility provides BGM-3 gyrostabilized marine gravimeters to the UNOLS community through the 'Potential Fields Pool Equipment' (PFPE) section. A SeaSpy Marine Magnetics magnetometer towfish and cable/reel system are available to UNOLS operators requiring a spare or replacement system.
The MISO Facility's self recording loggers are rated to 6000m operating depth and have been pressure certified for use on Alvin. They have been used extensively and successfully at hydrothermal vents in the Pacific and Atlantic Oceans by numerous investigators over the years.
