Marine Corps deploys oceanographic sensors From Ospreys | Defense Industry Daily

Trident Warrior is an annual large-scale field experiment in operational naval environments. US Marine Corps deploys four oceanographic sensors during the exercise from its MV-22Bs for the first time. These sensors were deployed from the back of C-130s or directly by ships previously. The data collected would provide the Marines with the best environmental awareness possible before conducting amphibious operations.
