Community site for RAFOS users


The RAFOS USERS' FORUM is intended for use by scientists who use subsurface float technology (floats using sound sources) to conduct research.  The objective is to foster collaborative research, and to facilitate cooperation between scientists for sharing valuable resources, e.g., sound sources, by providing a place to discuss upcoming projects, and ideas for projects, before the sources are in the water and the floats are deployed.

Listserv has been set up as a discussion forum for RAFOS users. If you would like to subscribe to or be removed from the listserv, please email Heather Furey at

Deep Floats Reveal Complex Ocean Circulation Patterns

Deep Floats Reveal Complex Ocean Circulation PatternsAcoustically tracked floats drift far below the ocean’s surface, providing fresh discoveries about deep-sea currents. A new archive gathers decades’ worth of float data into a central repository. By A. Ramsey, H. Furey. A. Bower, 2018 (WHOI)
