We are proud to announce receipt of a grant to develop new #technology for monitoring the impact of #deepseamining. Currently, no instrument exists that can monitor the #environmentalimpact of the resulting #sediment plumes. Sequoia aims to fill that need.

Sequoia instruments measure IOPs key to understanding water quality. IOPs, like absorption and scattering, depend only on the medium (e.g., seawater) and are measured using active sensors. They link seawater components to satellite signals.
