This XL table was created to summarise main information about 52 underwater video transects (incl. collection date, start and end position and time for each ROV (Remote Operated Vehicle) dive, summary of geo-biological observations, number of collected seabed samples) collected with ROV Holland onboard Irish Lights Vessel Granuaile during SeaRover 2018 research cruise between 2 July 2018 - 22 July 2018. SeaRover stands for Sensitive Ecosystem Assessment and ROV Exploration of Reef. This survey was commissioned by the National Parks and Wildlife Service (NPWS), funded by the European Maritime and Fisheries Fund (EMFF), and coordinated and led by INFOMAR (Integrated Mapping for the Sustainable Development of Ireland?s Marine Resources) and Ireland?s Marine Institute. Navigation problems were encountered during five dives, namely: Dive526_RB02, Dive527_RB03, Dive528_RB26, Dive529_ RB27, Dive549_PB05. Thus, these dive tracks were not included in the corresponding shapefile. However, other information about these dives is presented in this metadata table. None
