The spatial distribution of Scorpaenidae fish (thornyhead and rockfish), deep-sea sponges and corals, substratum types, and trawling evidence on and around Learmonth Bank, British Columbia (from Du Preez and Tunnicliffe 2011). Additional data collected and included in this data package, but not used in the original publication, include: distribution of other benthic fish (e.g., skates and flatfish), some invertebrates, sediment types (with percent coverage), and ROV operational information. All biotic and abiotic seafloor data were collected from the annotation of benthic video surveys (Table 1) conducted by the remotely operated vehicle (ROV) ROPOS (navigational data included as Table 2). Data attributes and definitions are also provided. This is was a Canadian Healthy Oceans Network (CHONe) Marine Biodiversity Project, MB-18.
