Seafloor data at these locations include multibeam bathymetry, high-resolution scanning altimetry, deep-towed sidescan sonar, seafloor digital photographs, sample locations, deep-towed magnetic data, and more. Each dataset is geospatially registered and incorporates metadata (e.g., sample geochemistry and time and depth of collection) that can be interactively accessed by the user. The user can control which datasets are shown on a map view of the area and the scale at which the map is viewed. Datasets with resolutions inappropriate for the scale at which they are being viewed are automatically removed from the map.
