Seafloor Sounding in Polar and Remote Regions (SSPARR) Concept

  • Fulfills need for seafloor depth measurements in areas not visited by ships, such as:

    • Arctic Ocean

    • Southern Ocean

    • Southern Pacific and Indian Oceans

  • NSF funded prototype

  • SSPARR buoy is an expendable device, deployable in open ocean or ice with target 5 year lifespan

  • Modular components can be integrated with other buoys

  • Expandable to use as an aid to navigation for under-ice vehicles

Seafloor Sounding in Polar and Remote Regions (SSPARR)

  • Buoy Control/Telemetry Module

    • Iridium Short Burst Data

    • Data Acquisition/Archiving & Control Sys.

    • May be floating or through-ice

  • Electromechanical Tether

    • Oil-filled hydraulic hose protects from ice damage

    • Integral electrical conductors

  • Depth Sounder Module

    • Nominal 20m depth to reduce ice damage, surface bubbles, cavitation

    • Internal power supply for 5 year lifetime

    • Energy output dependent on expected seafloor depth
