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 this year's 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.

New this year at NeMO Net: 1) the capability to communicate with three separate instruments on the seafloor, 2) the use of an omni-directional acoustic modem transducer on one instruments (the BPR), which increases the distance it can be located away from the surface buoy, and 3) the use of two independent satellite systems on the buoy, Orbcomm and Iridium, increasing the flexibility and reliability of the system.
