NeMO Net deployment

: NeMO Net: A near-real-time system which will link instruments located in the caldera of an active submarine volcano, 1 mile underwater and about 300 miles off Oregon's coast, to the Internet.

is a breakthrough in ocean engineering utilizing an acoustic modem to relay data from three temperature probes and a camera to a moored buoy, which in turn send the data to NOAA's Pacific Marine Environmental Laboratory via a GOES satellite. The prototype system, operational for one month in 1999 (see representative data below) will be succeeded by a more advanced system during a cruise beginning June 29, 2000. The new system, also to be located at the NeMO seafloor site, is planned to be operational for a year. (See Location Map).

Cumulative temperature data

Temperature is measured once an hour by each of three probes. Every 24 hours the resulting 72 temperature measurements are transmitted to the laboratory.
