FRONT COVER A high-density habitat consisting of deep-sea sponge, coral, and squat lobsters on a previously unmapped and unex- plored seamount in Papahānaumokuākea Marine National Monument. The photo was taken during E/V Nautilus cruise NA101. Image credit: D. Fornari (WHOI-MISO Facility) and OET The R/V Falkor team dove on “Rosebud,” a whale fall that was placed by researchers off San Diego, California, in La Jolla Canyon. Researchers noted changes in composition and life forms around the location in a beautiful, exciting dive investigating ecosystems unique to whale falls. Image credit: SOI b It Takes a Village! Managing Data from Okeanos Explorer By Barry Eakins, Susan Gottfried, Patrick Murphy, David Lovalvo, and Derek Sowers NOAA Ship Okeanos Explorer is a telepresence-enabled for near-real-time data sharing.

The UNH mapping team operates the state-of-the-art multibeam survey system, post-processes the data, and builds bathymetric products. NCEI performs long-term data stewardship and provides public discoverability and access to all data and products. Data management for Okeanos Explorer is a coordinated and collaborative effort between OER, OMAO, GFOE, UNH, and NCEI that has proven enormously successful.

These cruises collected 2 TB of multibeam swath bathymetry (1.79 million square kilo- 1,500 meters), 7 TB of multifrequency water column acoustics, 1,000 and 209 TB of high-resolution ROV seafloor video, including footage from 2,207 hours on bottom.
