These data include biological (i.e. animal counts) and environmental data from three remotely imagery surveys in Saanich Inlet, a fjord incising Vancouver Island, British Columbia, Canada. All three dives occurred in 2016. Data are organized by row, with each row representing a second of ROV video with metadata related to the ROV dive, water column data (e.g. temperature, salinity, dissolved oxygen, etc.) and species data (animal counts or binary presence/absence tallies). Data was collected as part of an MSc thesis (Gasbarro) and a Canadian Healthy Oceans Network II project (2.1.3).
