Full proposal for scientific drilling (852-CPP) 'GlaciStore: Understanding Late Cenozoic glaciation and basin processes for the development of secure large-scale offshore CO2 storage (North Sea)', submitted to Integrated Ocean Discovery Programme (IODP) April 2014. The proponent 'GlaciStore' consortium comprises research and industry organisations from the UK and Norway. The full proposal describes the relationship of the proposed research with the IODP science plan, regional background and previous work, and describes and illustrates three scientific objectives. The objectives are to investigate: glacial history and sedimentary architecture: fluid flow and microbial processes in shallow sediments; and the stress history and geomechanical models for strata that have experienced multiple glacial and interglacial cycles. The drilling and sampling strategy, standard drilling and logging operations, and the specialist measurements expected to be taken are described. Related initiatives and wider context of the proposed research also the initial and planned strategy for support from industry and government are outlined. The lead submitter, on behalf to the GlaciStore consortium is Heather Stewart, British Geological Survey (BGS).The 30 proponents from the UK and Norway (BGS, Institute for Energy Technology, Lundin Norway AS, SINTEF Energy Research, Statoil ASA, University of Bergen, University of Edinburgh and University of Oslo) and their expertise are listed. The full proposal is a pdf format file. This is restricted to the proponents for publication and to progress to a revised full proposal accepted for drilling by IODP. UKCCSRC Grant UKCCSRC-C1-30.
The spectacular botanical preservation and long occupation of Qasr Ibrim, Egypt make this site archaeobotanically matchless. 600 samples have been collected over 20 years covering a timespan of c. 1000 BC - AD 1800. The project has particularly focussed on the period AD 100-400 during which several new summer crops including sorghum, cotton, lablab and sesame first appear. These new crops are thought to be associated with the introduction of new irrigation technology, specifically a device known as the saqia, an ox-driven water wheel from which descends a conveyor belt to which pots are attached. It has never before been possible to examine this crucial change archaeologically and this project has allowed the investigation of when and how this great change happened. This has major implications for the history of agriculture in Africa and the Indian Ocean.
This dataset contains data from a marine geophysical and multibeam survey which took place in April 2012 in the area of Ardmucknish Bay on board the RV White Ribbon. This was a follow up survey to the previous work carried out in this area in 2011 (2011/4). QICS (Quantifying and monitoring potential ecosystem impacts of geological carbon storage) was a scientific research project funded by NERC; its purpose was to improve the understanding of the sensitivities of the UK marine environment to a potential leak from a carbon capture storage (CCS) system. The aim of the survey was to assess any affect the drilling of the borehole had on the underlying sediments. Sea floor bathymetry data were collected using a Kongsberg EM3002D multibeam system. Sub bottom seismic profiling data were collected using an Applied Acoustics surface tow boomer (STB). Technical details of the survey are contained in the BGS Report of Survey.

The QICS project (Quantifying and Monitoring Potential Ecosystem Impacts of Geological Carbons Storage) was established to improve our understanding of the potential impacts of CO2 release on the environment and to develop tools and best practice for monitoring sub-seabed CCS reservoirs. To monitor the potential impact of a CO2 leak to surficial benthic megafauna, cages of bivalves (the common mussel Mytilus edulis Linnaeus, 1758 and the king scallop Pecten maximus (Linnaeus, 1758)) were deployed at the gas release site and at a reference site in the QICS experiment - both within Ardmucknish Bay, Oban, Scotland. Replicate individuals were sampled at six time points over a 125-day period, which spanned both the 37-day injection and recovery phases of the experiment, in order to establish impacts to molecular physiology. Samples of bivalves were also simultaneously sampled from a reference site within the bay in order to contrast changes in physiology induced by the gas release with naturally variability in the physiological performance of both species. There was no evidence of gene regulation of either selected carbonic anhydrases (CAx genes) or the alpha subunit of sodium potassium ATPAses (ATP1A genes) in individual bivalves collected from the CO2 gas release site, in either species. In the common mussel Mytilus edulis there was only evidence for changes with time in the expression of genes coding for different classes of carbonic anhydrase. It was concluded that the effects of the plume of elevated pCO2 on ion-regulatory gene transcription were negligible in both species. Pratt et al. 2015.

The BGS digital Measured Urban Soil Chemistry data comprises the locations and concentrations (mg kg-1) of Arsenic (As), Cadmium (Cd), Chromium (Cr), Nickel (Ni) and Lead (Pb) in urban topsoil samples. The data is derived from the national, high resolution urban soil geochemical data from the BGS Geochemical Baseline Survey of the Environment (G-BASE) project. The information is relevant for the first stage of any assessment of risks to human health required by regulatory authorities in relation to land use and also for assessing ecological risk. Although point source PHE (Potentially Harmful Element) concentrations above respective SGVs (Soil Guideline Value) do not necessarily imply a significant health risk, they do highlight the need to consider whether or not there may be a risk. The urban soil chemistry data can be used to assist Local Planning Authorities to identify those areas where a risk assessment may need to be carried out by developers. Comparison of this spatially referenced geochemical data with information on current or historic land use and geological information might help environmental professionals decide whether high PHE concentrations in topsoils can be attributed to geogenic or anthropogenic sources. The point source data is based on an interpretation of the records in the possession of the BGS at the time the dataset was created.
The joint PHE-BGS digital Indicative Atlas of Radon in Great Britain presents an overview of the results of detailed mapping of radon potential, defined as the estimated percentage of homes in an area above the radon Action Level. The Indicative Atlas of Radon in Great Britain presents a simplified version of the Radon Potential Dataset for Great Britain with each 1-km grid square being classed according to the highest radon potential found within it, so is indicative rather than definitive. The joint PHE-BGS digital Radon Potential Dataset for Great Britain provides the current definitive map of radon Affected Areas in Great Britain.
The BGS has been commissioned by Defra to provide guidance on what are 'normal' levels of contaminant concentrations in English soils in support of the revision of the Part 2A Contaminated Land Statutory Guidance. The domain polygons and other data produced by this work are served as WMS here.
Data identifies landscape areas (shown as polygons) attributed with type of artificial or man-made ground. It indicates areas where the ground surface has been significantly modified by human activity. The scale of the data is 1:10 000 scale. Onshore coverage is partial with approximately 30% of England, Scotland and Wales available in the version 2 data release. BGS intend to continue developing coverage at this scale; current focus is to include all large priority urban areas, along with road and rail transport corridors. Types of artificial ground include: Infilled ground areas where original geology has been removed and then wholly or partially back filled includes waste or landfill sites. Landscaped ground areas where surface has been reshaped includes former sand and gravel workings for recreation and amenity use. Made ground man made features including embankments and spoil heaps. Reclaimed ground are areas of land fill, where new ground is created, usually in coastal margins, may be for example a consequence of draining of submerged wetlands and beach rebuilding. Worked ground areas where ground has been removed including quarries and road cuttings. Disturbed ground areas of ill-defined shallow or near surface mineral workings where distinction cannot be made between made and worked ground. Whilst artificial ground may not be considered as part of the 'real geology' of bedrock and superficial deposits it does affect them. Artificial ground impacts on the near surface ground conditions which are important to human activities and economic development. Due to the constantly changing nature of land use and re-use/redevelopment caution must be exercised when using this data as it represents a snapshot in time rather than an evolving picture hence the data may become dated very rapidly. The data are available in vector format (containing the geometry of each feature linked to a database record describing their attributes) as ESRI shapefiles and are available under BGS data licence.
CO2 was injected into shallow unconsolidated marine sediments in Ardmucknish Bay, Oban. 2D seismic reflection data were collected pre-release (15/05/2012), syn-release (17/05/2012, 18/05/2012, 19/052012, 29/05/2012, 30/05/2012, 20/06/2012) and after release stages (23/04/2014 and 24/04/2014) of CO2 help to better understand the spatial and temporal evolution of free gas anomalies within the overburden. The impact of CO2 on sediment acoustic properties, namely seismic reflectivity and attenuation, was also investigated. This dataset was collected by the National Oceanography Centre Southampton (NOCS) and the British Geological Survey (BGS) under the program QICS (Quantifying and monitoring environmental impacts of geological carbon storage) which was funded by the Natural Environment Research Council (NERC), with support from the Scottish Government. The dataset includes segy files, a presentation which summarises the main results and a map showing the spatial extent of the seismic data collected after gas release.
