1
Concepts for Integrating Ocean Science Sensors on Submarine Cables
2
Science Drivers (What’s it good for?) Tsunami detection and detail Sea floor movement Seismic event detection Mammal monitoring Expansion – interconnection to autonomous platforms and arrays
3
Direct and Indirect Connectivity Imbedded Sensors (at Repeater) Communication with other Sensor Platforms – Gliders – AUVs – Other Indirect power
4
Science on Cables Pressure Sensor Pressure Sensor Pressure Sensor Pressure Sensor Hydrophone Acoustic Modem Cable Repeater
5
Possible Acoustic Underwater Network Master Node connected to cabled infrastructure for near-real-time data transfer Network detects ranges between neighbor nodes – becomes an indicator of seafloor movements Add moorings for 3-D “sensor cloud” One or more sensors interfaced to each node Provide an acoustic interface (and positioning) for mobile platforms
6
Acoustic Hardware Sonardyne FETCH 100-6000 bps USBL compatible Teledyne Benthos SM-75 140-15,360 bits per sec data Modem/float/release LinkQuest UWM 2000 Up to 19,200 bps WHOI MicroModem Tritech AM-300 Modem
