Limited Tenders are invited for Design and development under water acoustic modem
Time- stamped data from pressure and attitude sensors are transmitted through an ROV hot stab connection or an acoustic modem
The methodology is easily extendable to real-time fatigue monitoring using a cabled system or acoustic modem
to transmit data to the surface.
Fetch is a long-life seabed sensor node that enables wireless data extraction via its integrated high speed acoustic modem
, made possible by the development of Wideband 2.
Part 1: 'Optical and Acoustic Sensors' which is comprised of seven articles ranging from optical fiber sensors, to designing a low-cost underwater acoustic modem
We were able to very quickly adapt the DeepSiren software-defined acoustic modem
to accommodate the unique requirements of the Arctic Submarine Laboratory.
When all of its T1 and fiber lines went down, the POTS line and a laptop with an acoustic modem
saved the day.
To remove the acoustic modem
bottleneck, various digital subscriber line (xDSL) technologies have been developed.
Each console contains: (1) an RTU, (2) a transceiver radio, (3) an acoustic modem
, (4) a master central processing unit, (5) valve, sphere, and sphere static position status displays, (6) remote/local valve control, (7) four manual valve switches, (8) eight timer relays for valve open/close, and (9) power supplies.

Sonardyne will be using Oceans '12 to showcase Fetch, it's long-life seabed logging node that enables sensor data to be gathered, stored and wirelessly extracted on demand via its integrated high speed acoustic modem
Some of the instruments in these ocean-floor monitoring systems can be configured to transmit the acquired data via acoustic modem
to the surface, where it can be obtained by a ship, or retransmitted via satellite from a buoy in the middle of the ocean to a laboratory ashore.
