Short summary

This dataset comprises 26-megapixel seafloor images collected from below ice and steeply sloped regions of the Southern Ocean (the western Weddell Sea; the Powell Basin; and the rapidly shallowing, iceberg-scoured Nachtigaller Shoal). These data were collected with the Ocean Floor Observation and Bathymetry System (OFOBS), an advanced towed camera platform incorporating various sonar devices to aid in hazard avoidance and seafloor mapping, for use in challenging, high-relief seafloor areas.
