During the California Borderlands expedition, we surveyed regions around Santa Barbara and San Nicolas islands. We dove to relatively shallow depths of 70-100 meters as we explored ancient shorelines. We used an autonomous surface vehicle (ASV) to create high resolution maps during the day and conducted ROV dives at night as we searched for sea caves. The Channel Islands are a host to biodiverse marine organisms and our ROV dives did not disappoint! Our geological exploration showed us a suite of sea creatures living in the mesophotic zone of the ocean, ranging from bright corals to marine invertebrates to looming sharks.
