SEAEXPLORER underwater glider by ALSEAMAR

KEY BENEFITS

  • Rechargeable Battery
  • Interchangeable Payload Sections
  • Large Ballasting Volume: High speed & Maneuverability
  • Large Payload Sections
  • Shallow & Deepwater Operations

The SEAEXPLORER underwater glider is a powerful autonomous sensing platform designed to collect water column data profiles with very wide spatio-temporal coverage (thousands of km and weeks to months of endurance).

Driven by buoyancy changes, the vehicle silently glides up and down the water column while collecting physical, chemical, biological and/or acoustic data depending on the fitted sensors.

The SEAEXPLORER glider is a very cost-effective solution for data collection as it reduces reliance on large vessels with high daily running costs: no surface supervision boat is required during the mission. The SEAEXPLORER is easy to operate and can be deployed and recovered by reduced crews in coastal waters using small boats.
