    The GeoSure data sets and reports from the British Geological Survey provide information about potential ground movement or subsidence in a helpful and user-friendly format. The reports can help inform planning decisions and indicate causes of subsidence. The methodology is based on BGS DiGMap (Digital Map) and expert knowledge of the behaviour of the formations so defined. This dataset provides an assessment of the potential for a geological deposit to show running sand behaviour under the action of flowing water, a characteristic usually of saturated sand and silt grade material. Complete Great Britain national coverage is available. The storage formats of the data are ESRI and MapInfo but other formats can be supplied.

    First sales (£GBP) from commercial fishing activity in Scottish seas of pelagic (midwater/oceanic) fish species, including UK registered fishing vessels wherever they land and non-UK vessels if landing into the UK, as recorded in last five years of published statistics. Data is redacted if less than five vessels operate within an ICES statistical rectangle (values = -1).

    First sales (£GBP) from commercial fishing activity in Scottish seas of shellfish (crustacean/mollusc) species, including UK registered fishing vessels wherever they land and non-UK vessels if landing into the UK, as recorded in last five years of published statistics. Data is redacted if less than five vessels operate within an ICES statistical rectangle (values = -1).

    Landings by live weight (tonnes) for commercial fishing activity in Scottish seas of demersal (bottom dwelling) fish species, including UK registered fishing vessels wherever they land and non-UK vessels if landing into the UK, as recorded in last five years of published statistics. Data is redacted if less than five vessels operate within an ICES statistical rectangle (values = -1).

    Demonstration and Research Marine Protected Areas (MPAs) are designated by Scottish Ministers under the Marine (Scotland) Act 2010. Sites can be established for the purpose of demonstrating, or carrying out research on sustainable methods of marine management or exploitation in Scottish territorial waters. Their application is not restricted to nature conservation. Proposals will be developed and assessed according to a set of specific guidelines which will examine the scientific case for a MPA, the level of support and the reasons why a MPA is the most appropriate mechanism to use.

    Effort (days) derived from UK-registered commercial fishing activity in Scottish seas using active demersal gears (bottom trawls, bottom seines, and dredges), as recorded in last five years of published statistics. . Data is redacted if less than five vessels operate within an ICES statistical rectangle (values = -1).

    Scottish underwater TV surveys to estimate Nephrops burrow distribution and abundance, from Nephrops Functional Units of significance to Scotland. Underwater TV footage is taken at specified stations within Functional Units. The underwater camera is mounted on a towed sledge and tow duration is 10 minutes. Records of Nephrops burrows, Nephrops and other benthic fauna is recorded onto DVD for analysis and review.

    Effort (days) derived from UK-registered commercial fishing activity in Scottish seas using passive gears (set nets, lines, creels/pots and traps), as recorded in last five years of published statistics. Data is redacted if less than five vessels operate within an ICES statistical rectangle (values = -1).

    The GeoSure data sets and reports from the British Geological Survey provide information about potential ground movement or subsidence in a helpful and user-friendly format. The reports can help inform planning decisions and indicate causes of subsidence. The methodology is based on BGS DiGMap (Digital Map) and expert knowledge of the behaviour of the formations so defined. This dataset provides an assessment of the potential for a geological deposit to shrink and swell. Many soils contain clay minerals that absorb water when wet (making them swell), and lose water as they dry (making them shrink). This shrink-swell behaviour is controlled by the type and amount of clay in the soil, and by seasonal changes in the soil moisture content (related to rainfall and local drainage). The rock formations most susceptible to shrink-swell behaviour are found mainly in the south-east of Britain. Clay rocks elsewhere in the country are older and have been hardened by burial deep in the earth and are less able to absorb water. The BGS has carried out detailed geotechnical and mineralogical investigations into rock types known to shrink, and are modelling their properties across the near surface. This research underpins guidance contained in the national GeoSure dataset, and is the basis for our responses to local authorities, companies and members of the public who require specific information on the hazard in their areas. The BGS is undertaking a wide-ranging research programme to investigate this phenomenon by identifying those areas most at risk and developing sustainable management solutions. Complete Great Britain national coverage is available. The storage formats of the data are ESRI and MapInfo but other formats can be supplied.
