        "abstract":"The sampling cruise took place in August 1992 in the region of the Hebridean Terrace west of the Outer Hebrides in the vicinity of the Barra Fan aboard the RRS Charles Darwin. The purpose was to locate and sample marine gas and il seeps on the seafloor. The cruise was undertaken jointly by the British Geological Survey, Marine Biological Association, Plymouth and Dunstaffnage Marine Laboratory in order to integrate the geology with the biology and chemistry of these seeps. Seabed samples were collected using gravity corer; box corer, Agassiz trawl and epibenthic sledge. CTD data were also collected. Sea floor data were collected using Echo sounder. Subsurface seismic data were gathered using Pinger. Technical Details of the survey are contained in BGS cruise report WB/92/25 or WB/92/212.",
        "additional_info":"For more detailed information on the acquisition equipment and data collection techniques, operational standards, data processing methods and quality control procedures used on this survey see the Report of Survey/Cruise Report and associated documentation where available. The information available may vary depending on the age of the survey. Data are checked and loaded to the BGS Coastal and Marine data management system following BGS marine data management procedures.",
