How We Use Seafloor Mapping Data to Guide ROV Exploration! | Nautilus Live

Our current expedition to #JohnstonAtoll uses the mapping information gathered on our last expedition where we were able to map 27,788 square kilometers in and around this are of the #PacificRemoteIslandsMarineNationalMonument (PRIMNM). In this video, our #CorpsofExploration explain how we gather and use that #seafloormapping data and use it to determine where to dive with #ROVHercules. Johnston Atoll is located in the #PrimeCrustZone, an area of the #Pacific with oceanographic conditions observed to concentrate deep-sea minerals, including economically valuable metals and rare earth elements. The questions of biological connectivity are particularly relevant around Johnston Atoll as the area contains rich biodiversity and is the closest deep water marine protected area to Papahānaumokuākea Marine National Monument and in the same region as the Kingman Reef, Palmyra Atoll, and Kiribati’s Phoenix Islands Protected Area. Thanks to our mapping team, scientists on this expedition can pinpoint the best places to dive for their geological and biological research.
