This was the first in a series of surveys to be conducted in this location. A camera system mounted on the autonomous underwater vehicle (AUV) Autosub6000 was deployed during RRS Discovery cruise 377/8 (D377/8), and images were collected from four 4.7 km transect lines. The raw images are provided in this collection, available on request. The images are provided in a raw format unique to the Grasshopper 2 camera system. The aim of the survey was to undertake high-resolution acoustic seabed mapping and visual imagery in a Marine Protected Area, in order to highlight the capability of AUV technology for offshore seabed mapping and benthic assemblage assessment. The work was initially undertaken as part of a Defra-funded project \"Investigating the feasibility of utilizing AUV and Glider technology for mapping and monitoring of the UK MPA network (MB0118)\", Case study 2: Shallow-water AUV mapping off SW UK (https://nora.nerc.ac.uk/id/eprint/500733/), and the Natural Environment Research Council (NERC) funded Autonomous Ecological Surveying of the Abyss project (NE/H021787/1), involving scientists from the National Oceanography Centre (NOC), UK. Other supporting datasets available on request include AUV-based multibeam bathymetry, sidescan sonar and CTD data.", "includedInDataCatalog": { "@id": "http://portal.medin.org.uk/portal/json-ld/catalog.jsonld" }, "conditionsOfAccess": [ "access: No limitations apply", "access: Data are freely available", "use: No conditions apply" ], "distribution": [ { "@type": "DataDownload", "name": "Published dataset - doi:10.5285/090239b1-b7dd-1030-e063-6c86abc0e183", "description": "Benoist N., Bett B.J., Morris K., Ruhl H.
