The Bedrock Aquifer Productivity Scotland dataset forms part of the BGS Hydrogeological Maps of Scotland data product. This product is comprised of three datasets: Bedrock Aquifer Productivity Scotland; Superficial Aquifer Productivity Scotland; and Groundwater Vulnerability Scotland. Aquifer productivity is a measure of the potential of aquifers to sustain a borehole water supply. The Bedrock Aquifer Productivity Scotland dataset version 2 (2015) indicates the location and productivity of bedrock aquifers across Scotland, and their groundwater flow characteristics. Developed as a tool to support groundwater resource management, the dataset provides a guide to aquifer characteristics at a regional scale, and may be useful to anyone interested in learning more about, assessing or managing groundwater resources across Scotland. The dataset is delivered at 1: 100 000 scale; the resolution of the dataset being 50 m and the smallest detectable feature 100 m.
Offprints of articles relating to Geomagnetism from 1822 to 1981. Offprints collected by Kew Observatory, Meteorological Office, Edinburgh and Greenwich Observatory (Herstmonceux castle). The first page of each offprint has been digitised to produce a finding aid.
Results of two sampling campaigns conducted in Kwale County Kenya in March and June 2016 by GHS/UPC as part of the Gro for GooD project. Water samples from over 79 groundwater and 6 surface water (SW) locations were analysed for major ions, stable isotopes, selected trace constituents, electrical conductivity, nitrates, ammonia, pH, DO (Dissolved Oxygen), Eh (oxidation / reduction potential), Temperature, TOC (Total Organic Carbon) and field alkalinity. Most locations were sampled in both March (dry season) and June (wet season). Geology at each location recorded as follows: P - Pliocene Sands, Pls - Pleistocene Sands, Plc - Pleistocene corals.

Isotope analysis data. Project details: The continental crust is our only archive of Earth history; not just of the crust itself but of the hydrosphere, atmosphere and biosphere, and of the deep Earth through its interactions with the crust. This archive, like the rock record itself, is incomplete and much effort is focused on interrogating the crust to gain a clearer and more complete picture of Earth history. The continental rock record is episodic with, for example, ages of igneous crystallization, metamorphism, continental margins, and seawater and atmospheric proxies distributed about a series of peaks and troughs that in part correspond with the cycle of supercontinent assembly and dispersal. At the core of the debate is what these well-established peaks of ages in the geological record represent and how they develop. The peaks of ages correspond with periods of global assembly of continents to form supercontinents. The project will address whether the peaks of ages are primary features associated with supercontinent assembly or break up, or they are they secondary features representing greater preservation potential at the times of supercontinent assembly. Our work will focus on the Rodinian supercontinent cycle, which extends from initiation of convergent plate interaction around 1.7 Ga, to continental collision at 1.1-1.0 Ga during the Grenville orogeny, to final breakup of the supercontinent by 0.54 Ga. Detrital zircons from sedimentary units throughout the supercontinent cycle provide a record of the magmatic activity for which the igneous rocks are often no longer preserved. We will determine (i) the ages ranges of magmatic activity preserved in the sedimentary rocks in the 600 Ma pre-collision phase, and (ii) how and when the distinctive Grenville peak of ages developed by comparing the zircon record from samples pre-, syn- and post- Rodinian supercontinent assembly with estimated volumes of magma and numbers of zircons produced during the same interval. This will differentiate primary generation processes from secondary processes, constraining when the dominant age peak developed, the tectonic processes that operated, and hence the method by which it developed. The wider implications of when the continental crust formed are considerable. Studies of continental growth continue to uncritically assume that the geological and isotopic record provide insight into processes of crust formation. Until it can be established whether the record is the outcome of generational or preservational processes, or a combination of both, then drawing conclusions on this fundamental question in the Earth Sciences are premature. If the record is a preservational record then this impacts on understanding continental growth through time and on secondary questions of how the crustal record is used to unravel the temporal evolution of the hydrosphere and biosphere, and the distribution of mineral deposits.
The Groundwater Vulnerability Scotland dataset forms part of the BGS Hydrogeological Maps of Scotland data product. This product is comprised of three datasets: Bedrock Aquifer Productivity Scotland; Superficial Aquifer Productivity Scotland; and Groundwater Vulnerability Scotland. The Groundwater Vulnerability Scotland dataset version 2 (2015) shows the relative vulnerability of groundwater to contamination across Scotland. Groundwater vulnerability is the tendency and likelihood for general contaminants to move vertically through the unsaturated zone and reach the uppermost water table after introduction at the ground surface. The groundwater vulnerability dataset was developed as a screening tool to support groundwater management at a regional scale across Scotland, and specifically to aid groundwater risk assessment. The data can be used to show the relative threat to groundwater quality from contamination, by highlighting areas at comparatively higher risk of groundwater contamination. The dataset is delivered at 1: 100 000 scale; the resolution of the dataset being 50m and the smallest detectable feature 100 m
This poster on the UKCCSRC Call 2 project Advanced Sorbents for CCS via Controlled Sintering was presented at the CSLF Call project poster reception, London, 27.06.16. Grant number: UKCCSRC-C2-206. Calcium looping shows significant promise for CO2 capture. The process can lead to an energy penalty as low as 6 - 8 % including the compression of the lean CO2 stream, compared to 9.5 - 12.5 % for amine-based post-combustion capture. To implement this technology on an industrial scale, a large quantity of CaO-based sorbent will be required, therefore the sorbent must be capable of being regenerated and reused.
