Although extensive previous ROV dives have occured on the seamount proper, there is deep rocky habitat southeast of the seamount that could harbor additional communities of corals and sponges.

Musick, Pan Am’s Chief Pilot, who at one time held more records and honors than any other active flier, including the 1935 Harmon Trophy which recognized him as “the world’s outstanding aviator.”. The main objective of this expedition is to collect deepwater baseline information to support science and management decisions in and around U.S. marine protected areas in the central Pacific. In fact, barely any trace of this trailblazing fleet of flying boats still exists above or below the water. E/V Nautilus and its Corps of Exploration ventured further west and south than ever before in 2019, the fifth year of exploration in the Eastern Pacific Ocean. This expedition continues the multi-year SUBSEA (Systematic Underwater Biogeochemical Science and Exploration Analog) Research Program, a partnership between NASA, NOAA, and various academic research centers. We will conduct seafloor mapping and acquire video, biological, chemical, and geological samples in deep-sea portions of the Pacific Remote Islands Marine National Monument in order to better understand marine habitats, biogeographic patterns, seafloor mineral distribution, and the geologic history of these areas. From the South Pacific to California's coast, documenting deepwater coral colonies to the peaks of underwater volcanoes, the 2019 Nautilus expedition has spanned six months and hundreds of hours of ROV dives. Systematic mapping of the seafloor by echosounder commenced nearly a century ago, however, more than 80% of the world’s seafloor is still not mapped, even at a resolution of 1km, and the eastern Pacific Ocean is no exception. The nearly 200 day expedition season included mapping and ROV exploration in national marine sanctuaries along California, the second expedition of the multi-year NASA SUBSEA program, and sailing out to remote regions of the central Pacific to search for two maritime heritage sites and document deepwater coral communities. Fish and Wildlife Service within the Pacific Remote Islands National Marine Monument, both expansive protected areas about which comparatively little is known, in large part due to their remote locations. One targeted region is a series of linear seamounts known as the Moonless Mountains, and mapping will support the analysis of the geological structure and processes of the relationship of these seamounts to the adjacent fracture zone. Biological specimens will help define biogeographic boundaries, depth distribution and diversity of species, and observe the basic biology and ecology of these ecosystems, compared to other regions. Previous expeditions within this region provided a glimpse into the deep-sea habitat and mesophotic ecosystems of American Samoa. While the diversity of species in shallow waters is relatively well known, deeper waters are not. Aviation pioneer Earhart is considered one of the most intriguing and inspirational figures in history whose loss was so profound it has been felt for decades, spawning countless theories about how and where she disappeared. OET mapped more of the ocean’s seafloor this year than any on record, over 135,340 km2. This year also marked the first deployment of our mobile capabilities, as OET and the University of New Hampshire’s Center for Coastal and Ocean Mapping worked with the Thunder Bay National Marine Sanctuary to map lakebed habitat in northwestern Lake Huron.

The SUBSEA Science team is using ROVs to observe, survey, gather instrument data, and collect samples from analog environments to potential volcanic hydrothermal systems on other Ocean Worlds, such as Enceladus, a moon of Saturn. While the foundations were shifting, changing uplift rates and glacial cycles also resulted in fluctuating sea levels eroding away the islands, leaving strands of sedimentary rocks both above and below the current sea level as evidence of ancient paleoshorelines.

GFNMS recently expanded to double in size and now protects 3,295 square miles, thus requiring further exploration of deep-ocean habitats. Launching the 2019 Nautilus Expedition season, the Osborn Bank expedition is a continuation of a multi-year collaborative expedition to collect high-resolution mapping data and characterize submerged shorelines in the California Borderland region. Launching the 2019 Nautilus Expedition season, the Osborn Bank expedition is a continuation of a multi-year collaborative expedition to collect high-resolution mapping data and characterize submerged shorelines in the California Borderland region. After great dives along Santa Lucia Bank overnight, the team is headed into the Channel Islands National Marine Sanctuary for continued exploration dives later today! During this expedition, a variety of engineering tests will be conducted with ROVs Little Hercules, Atalanta, and supportive equipment. Expedition objectives include conducting a biological census of deep-sea and mesophotic communities, exploring a volcanically active seamount, seafloor mapping, and targeted sampling for potential new species and further environmental analysis.
