LISST use in nodule collection system trials in the Clarion Clipperton Zone

November 17, 2022

Sequoia Scientific, Inc. Reaching New Depths with The Metals Company

This Fall deep down in the Pacific Ocean, Sequoia’s prototype LISST-RTSSV instrument will be deployed during a series of deep sea collector tests in coordination with The Metals Company. LISST-RTSSV has been developed for in situ measurement of particle size distribution, particle concentration, and particle settling velocity in near real-time. In this effort, LISST-RTSSV will be mounted on an ROV for investigating particle characteristics of sediment plumes generated by undersea collection operations. These data are key to developing and validating models for plume extent and evolution.
