Global Subsurface Flanking Moorings

The Global Flanking Moorings are taut subsurface moorings with a syntactic sphere at the top, approximately 2500-4000 m of wire rope, glass spheres mounted to mooring chain for backup recovery, dual acoustic releases, and a deadweight anchor.

They have an acoustic modem, and fixed instruments in the upper sphere and along the wire. The mooring have acoustic modems, and gliders will be used as data shuttles to provide access to the data from the Flanking Moorings as well as some capability to interact with these instruments.
