During mission AS5M094, the AUV was programmed to replicate parallel 1-to-2 km long transect lines in four sites spaced by an array of scales, located 0, 15, 30, 100 km South from the northern border of the UK-1 exploration area. The Grasshopper2 GS2-GE-50S5C camera mounted on the AUV collected vertically orientated still images at a target altitude of 3 m above the seabed, with one image being captured per second. These images were colour-corrected to enhance visual fidelity and converted from original 8-bit RAW to JPG images. The image set includes images collected above 1.6 m and below 3 m altitude, which was corrected for the lever-arm corrected AUV pitch. The data were collected by scientists from the National Oceanography Centre, Southampton, UK as part of the NERC-funded Seabed Mining And Resilience To EXperimental impact (SMARTEX) project (NE/T003537/1).","keywords":"","publicationState":"citable","dataPublishedTime":"2025-10-08T11:15:10","doiPublishedTime":"2025-10-08T11:15:10","updateFrequency":"","status":"completed","result_field":{"ob_id":"https://catalogue.ceda.ac.uk/api/v2/observations/44889/?format=json","dataPath":"/bodc/soc250982","oldDataPath":[],"storageLocation":"internal","storageStatus":"online","volume":0,"numberOfFiles":0,"fileFormat":null},"timePeriod":"https://catalogue.ceda.ac.uk/api/v2/times/12721/?format=json","geographicExtent":"https://catalogue.ceda.ac.uk/api/v2/bboxes/4887/?format=json","nonGeographicFlag":false,"phenomena":[],"dataLineage":"The data are archived on the British Oceanographic Data Centre (BODC)'s space at the Centre for Environmental Data Analysis (CEDA) and assigned a DOI.
