About NeMO

NOAA Vents Program

is a breakthrough communication system that allows scientists on shore to send commands to, and get data back from, monitoring instruments on the seafloor. It is an outgrowth of NOAA/PMEL's Tsunami research program, which developed DART, a system for near-realtime tsunami detection using bottom pressure recorders and moored buoys. Since 1999, NeMO Net has gradually increased the capabilities of this basic system in an effort to adapt it to the more complex demands of a seafloor observatory. Each year since then, NeMO Net has been developed further, beginning with one-way communication from a digital camera on the seafloor, to a system with multiple instruments with two-way communication to a single surface buoy. The goal is to keep developing this system into a true seafloor observatory.

This year at NeMO Net: there are two instruments on the seafloor that each communicate with the surface buoy. One instrument is an interactive fluid sampler (RAS) at the ASHES vent field, and the other is a bottom pressure recorder (BPR) located near the center of the caldera. All subsea communication this year is via omni-directional acoustic modem transducers, which increase the distance that seafloor instruments can be located away from the surface buoy. All satellite communication this year is via an Iridium telephone link.
