This dataset provides access to the sea-floor videos and locations of bottom videos acquired with a SeaViewer 6000 HD Sea-Drop video camera on the Mini SEABed Observation and Sampling System (MiniSEABOSS) aboard the Research Vessel (R/V) Rafael during USGS field activity 2016-005-FA (May 2 to May 7, 2016) and aboard the R/V Tioga during USGS field activity 2017-022-FA (May 4, 2017). These data were collected to characterize the sea floor by identifying sediment texture and to ground-truth acoustic data collected during USGS field activity 2013-003-FA (Ackerman and others, 2016). Bottom videos serve as a means to visually classify grain size and identify sea-floor habitats, and they are especially important for sample sites where no physical sediment sample was collected.
