The African continent is slowly splitting apart along the East African rift valley, a 3000 km-long series of deep basins and flanking mountain ranges. This process may eventually lead to the formation of a new ocean, but on a time scale of millions of years. In the remote Afar depression in northern Ethiopia, Earth's outermost shell, usually a relatively rigid, 150 km-thick plate, has been stretched, thinned and heated to the point of rupture, to the extent that a new ocean is about to form. Below the surf...
In this urgency proposal we will deploy seismometers for 1 year to record aftershocks from sequence of 4 major earthquakes with magnitudes between 7.1-7.6. These recordings and other recordings of earthquakes from around the globe will allow us to delineate with high accuracy the plate interfaces of the new and old subducting slabs and image the slab structures at depth. The structure of the old and new subduction zones will illuminate the processes occurring at depth which are shifting the force balance i...
This is a daily weather dataset that was produced to support hydrological modelling of the Thames catchment including use of the JULES land surface model https://jules.jchmr.org/ . It contains daily values of each of seven weather variables: air pressure, precipitation, wind speed, air temperature, wet bulb temperature, short wave radiation and cloud cover. The dataset was developed from the Met Office Integrated Data Archive System (MIDAS) to enable the calibration of multisite, multivariate weather gener...
Archive of reports, correspondence, records of tunnel and dam site examinations, borehole records relating to the North of Scotland Hydro-Electric Board's schemes in the Scottish Highlands c.1945-1970. Arranged by hydro-electric scheme.
Database of hydrogeological properties measured on core samples. Contains most determinations generated by BGS Wallingford Physical Properties Lab but some data is only available on paper. High quality data produced to strict laboratory quality standards.
The map shows the potential for the rocks to supply groundwater and the type of groundwater flow within the rocks. The dataset reattributes polygons in the Digital Geological Map Data of Great Britain - 625k (DiGMapGB-625) Bedrock version 5 dataset to indicate whether the bedrock is an aquifer, the type of flow through the aquifer (fracture and fissure flow or intergranular flow) and how productive the aquifer is likely to be. The dataset is based on the known hydrogeological properties of rock types. The ...
Hydrogeological maps of the UK at various scales. Hydrogeological maps of the UK provide information on major aquifers, including geological and lithological information, surface drainage systems and water quality issues. The 23 maps show information on surface water features, the three dimensional geometry of aquifers, groundwater levels, abstractions and quality including saline intrusion in varying amounts of detail. They range in scale from 1:625 000, for the national map of the hydrogeology of England...
Dataset contains hydrogeological zones with attached basic informations to the extent given to edict of Ministry of Agriculture Decree no.391/2004 Coll., i.e. information about zone name, numerical identifier, river basin managers and territorial identification, additional data on natural characteristics. The basic natural characteristics of zone include geological unit, group of zones, lithology, stratigraphy of Cretaceous group of zones, type of Quarternary sediment in laden layer of zones, type of aquif...
The Hydrogeological Map of Switzerland at 1:500,000 scale consists of two sheets. The first sheet shows the various groundwater resources in Switzerland and provides information about productivity. The second sheet shows the vulnerability of groundwater resources to possible contamination.
Data for Uganda includes analytical, field, isotope and borehole data. Data for Tanzania includes chemistry, field, isotope and borehole data. Borehole data from the Makutopora Wellfield is also included. This data was collected to investigate the resilience to climate change in sub-Saharan Africa (Tanzania and Uganda) of intensive groundwater abstraction from weathered crystalline rock aquifer systems. The sustainability of such abstractions was investigated by examining historical aquifer responses to cl...
