Our neutrally buoyant tether is an integral part of the POLARIS project developed by ETH Zurich, which involves the use of an innovative autonomous underwater vehicle designed for research applications in the fields of climate and security.
One of the project’s main objectives is the accurate measurement of ice thickness from below using a non-invasive method. As the vehicle moves beneath the lake surface, it continuously collects measurement data, generating a high-resolution dataset capable of mapping the spatial distribution of ice thickness.
This approach provides highly precise data without the need to drill through the ice, avoiding surface disturbance and reducing risks for personnel operating in extreme environmental conditions.
Within this demanding operational context, our neutrally buoyant tether plays a key role in ensuring system reliability, vehicle manoeuvrability, and overall mission safety.
