Results of geotechnical testing carried out, at various depth intervals, on shallow cores or boreholes collected by BGS from the UK Continental Shelf (UKCS). The bulk of the data north of 56N are in digital form and result from testing carried out onboard survey vessels using hand-held test equipment (penetrometers and shear vanes). These values are averaged for each test interval, and are expressed in kilopascals (kPa). There are approximately 6,000 test results in the dataset. Some more detailed test information, in non-digital and report form, is held for selected sites. For most sites where digital data are not available, geological descriptions of core material contain semi-quantitative information on the stiffness of the material. Geotechnical knowledge is required to understand and interpret the results if they are to be used as a basis for engineering studies. Core material is managed as part of the BGS materials collection and is available for examination, testing or subsampling. The data are stored as part of the National Geoscience Data Centre (NGDC) and the Marine Environmental Data and Information Network (MEDIN) Data Archive Centre (DAC) for geology and geophysics. Data are delivered via the 'Offshore samples: geotechnical data' layer on the BGS GeoIndex. Reference: Fannin, NGT. (1989) Offshore Investigations 1966-87.

The Marine Aggregate Levy Sustainability Fund (MALSF) commissioned a series of Regional Environmental Characterisation (REC) surveys via the Marine Environment Protection Fund (MEPF) to develop understanding of submerged habitats and heritage in Britain. The aim was to acquire high quality data to enable broad scale characterisation of the seabed habitats, their biological communities and potential historic environment assets. The surveys were conducted in the following areas - Outer Bristol Chanel (2003 – 2005), Eastern English Channel (2005 – 2006), South Coast (2007 - 2010), Outer Thames (2007), East Coast (2008 - 2009), Humber (2008 - 2009). The Geology and Geophysics component of the data are archived by British Geological Survey (BGS) in the Marine Environmental data and Information Network (MEDIN) Data Archive Centre (DAC) for Geology and Geophysics. The data includes bathymetry, sidescan sonar, sub-bottom profiler, magnetometer, seabed video and photographs, Particle Size Analysis (PSA) data, vibrocore (logs and images). Data are delivered via the BGS Offshore GeoIndex www.bgs.ac.uk/GeoIndex/offshore.htm. Additional data are available on request enquiries@bgs.ac.uk. Other data types have been archived with the other MEDIN DACs as appropriate (UKHO DAC for bathymetry data and DASSH DAC for biological data). The MALSF ceased operation at the end of March 2011 (http://www.marinealsf.org.uk/).
