Caisson Installation Complete at Southern Hydrate

Caisson Installation Complete at Southern Hydrate

This caisson is buried to about 1 m depth beneath the sediments. Next year a broadband seismometer will be placed in it and connected to the cable, providing real-time detection and location of earthquakes. A cover was placed over the caisson to keep sediment from falling into it and animals out. Photo credit: NSF-OOI/UW/CSSF.
