This sampling survey was a trial with the MV Wimpey Sealab to drill in water depths greater than the depth in which the Whitethorn could operate. Five boreholes were drilled before a contract was awarded for further boreholes in North Sea.

The dataset describes the relative vulnerability of groundwater to contamination across Scotland, by means of five relative classes ranging from 1 (lowest vulnerability) to 5 (highest vulnerability). The dataset is a screening tool that can be used to show the relative threat to groundwater quality from contamination across Scotland. It can provide guidance on the vulnerability of groundwater at a regional scale, highlighting areas at comparatively higher risk of groundwater contamination, and can help indicate the degree of specific site investigation required for a new development or activity. It is designed to be used at a scale of 1:100,000 and should be regarded as a tool to aid groundwater risk assessment rather than a complete solution.

This marine geophysical and multibeam survey was undertaken in July/August 2012 off south-west Tiree by the British Geological Survey (BGS) on behalf of Marine Scotland on board the Northern Lighthouse Board vessel NLV Polestar. Sea floor bathymetry data were collected using a Kongsberg EM3002D multibeam system. Sub bottom seismic profiling data were collected using a surface tow boomer. The data are archived by BGS and are also available on Marine Scotland Interactive (MSI) - http://www.gov.scot/Topics/marine/science/MSInteractive/Themes/Renewables/Data. Multibeam bathymetry data are available from the UKHO Bathy DAC, https://www.gov.uk/guidance/inspire-portal-and-medin-bathymetry-data-archive-centre. Backscatter data are available from the backscatter layers in the BGS Offshore GeoIndex. Technical details of the survey are contained in BGS Report of Survey CR/12/099, https://nora.nerc.ac.uk/id/eprint/529501/.

This British Geological Survey (BGS) marine geophysical survey took place in July 2013 approx 15km east of the island of Mingulay on board the RV Calanus. The purpose was to obtain seismic profiles across the coral mounds of the Mingulay Coldwater Coral Reef. An additional line was collected in Sound of Mull as a test. It has provided useful information on a submarine landslide. Sub bottom seismic profiling data were gathered by BGS using an Applied Acoustics surface tow boomer (S-Boom). These data are archived by BGS. Technical details of the survey are contained in BGS Report OR/13/033. GeoIndex Offshore - https://mapapps2.bgs.ac.uk/geoindex_offshore/home.html?cruise=2013/7&.

The North of Celtic Deep rMCZ survey was carried out during 7th – 9th February 2012 on the RV CEFAS Endeavour cruise CEND 03/12. Multibeam bathymetry and backscatter data were collected in between sampling stations. These data are archived with the Marine Environmental Data and Information Network (MEDIN) Data Archive Centres (DACs) including the British Geological Survey (BGS) DAC for geology and geophysics, The Archive for Marine Species and Habitats Data (DASSH) and the United Kingdom Hydrographic Office (UKHO) bathymetry DAC. The full site data package including raw is also available on request from BGS.
