This 5 km resolution grid indicates what borehole yields (in l/s) can reasonably be expected in different hydrogeological units. The ranges indicate the approximate interquartile range of the yield of boreholes that have been sited and drilled using appropriate techniques. Groundwater productivity is given in liters per second. Detailed description of the methodology, and a full list of data sources used to develop the layer can be found in the peer-reviewed paper available here: http://iopscience.iop.org/article/10.1088/1748-9326/7/2/024009/pdf The raster and a high resolution PDF file are available for download on the website of British Geological Survey (BGS): http://www.bgs.ac.uk/research/groundwater/international/africanGroundwater/mapsDownload.html Groundwater Supply

This 5 km resolution grid presents groundwater storage in Africa (in mm). This parameter was estimated by combining the saturated aquifer thickness and effective porosity of aquifers across Africa. For each aquifer flow/storage type an effective porosity range was assigned based on a series of studies across Africa and surrogates in other parts of the world. Groundwater storage is given in millimeters. Detailed description of the methodology, and a full list of data sources used to develop the layer can be found in the peer-reviewed paper available here: http://iopscience.iop.org/article/10.1088/1748-9326/7/2/024009/pdf The raster and a high resolution PDF file are available for download on the website of British Geological Survey (BGS): http://www.bgs.ac.uk/research/groundwater/international/africanGroundwater/mapsDownload.html Groundwater Storage

Fragmented Data

<p>The urban subsurface is key to developing sustainable urban futures (SDG 11). Yet, as is well acknowledged, geoscientists face many challenges in engaging stakeholders and communities with the urban subsurface, as well as the challenges associated wtih fragmented data sources, knowledge gaps, citizen ‘oversight,’ and challenging subsurface cultural associations (Bricker et al. 2017, 2019). In this paper we present a case for the value of the intersections between geoscience and creative practices (from visual methods to participatory arts) in helping to address some of these challenges. To make our case we present preliminary findings from a collaboration between geoscientists and science communicators based at the British Geological Survey, and a cultural geographer experienced in researching and creating art-science collaborations. We explore three things:</p><p>We close our discussion with an invitation to join us in forming a network exploring the potential of art-geoscience collaborations for understanding, using and preserving the urban subsurface. </p>

Airborne geophysical surveys in Greenland in 1998. Geology of Greenland Survey Bulletin, 183, 34-38. https://doi.org/10.34194/ggub.v183.5202 _______________ Airborne geophysical surveying in Greenland during 1998 consisted of a magnetic project referred to as ‘Aeromag 1998’ and a combined electromagnetic and magnetic project referred to as ‘AEM Greenland 1998’. The Government of Greenland financed both with administration managed by the Geological Survey of Denmark and Greenland (GEUS). With the completion of the two projects, approximately 305 000 line km of regional high-resolution magnetic data and approximately 75 000 line km of detailed multiparameter data (electromagnetic, magnetic and partly radiometric) are now available from government financed projects. Figure 1 shows the location of the surveyed areas with highresolution geophysical data together with the area selected for a magnetic survey in 1999. Completion of the two projects was marked by the release of data on 1 March, 1999. The data are included in the geoscientific databases at the Survey for public use; digital data and maps may be purchased from the Survey.

Direct Applicability

AbstractMaps and plans represent essential tools of the trade for planners and applied earth scientists alike, and thematic maps produced by geologists should be able to be understood by planners. Geology, geotechnics, geomorphology, hydrogeology and related sciences can provide essential data on some of the constraints to development and resources for development. Recognition of these permits safer, more cost- effective planning and development, and allows rational decisions to be taken as far as the exploitation of resources is concerned. Consequently the Department of Environment had been commissioning research to investigate the best means of collecting, collating, interpreting and presenting, in sets of maps and reports, geological results of direct applicability to land-use planning. For example, some years ago initial studies in thematic mapping were undertaken by the British Geological Survey and more recently a number of private consultants have carried out such work. Unfortunately, the results of some of these surveys have not, as yet, been published.
