Evaluation of Regional Slope Stability of the European Continental Margin - Raster datasets (Bathymetry NW Illuminated)

PROJECT DETAILS ONLY - NO DATA. There is a large deal of uncertainty as to the levels of stabilty of slope components of the European margin, other than localised detailed surveys completed using combination of sidescan sonar and swath bathymetry in recent years. Thesse surveys have revealed that the factors which control the locations of areas of potential slope failure are complex and manifold. Clearly slope gradients, sediment supply, physical oceanographic conditions and sediment type all have major roles to play, but their interaction is far from well understood. One of the problems to be addressed is the lack of a comprehenisve and focussed data synthesis with which to derive and test models of slope behaviour. A promising way in which this shortfall could be rectified would be to combine selected parts of the extensive survey database acquired by the telecommunications industry in it search for suitable pathways in which to lay earlier copper-core and now more recently, fibre-optic cable systems. These data would be interpreted in conjunction with a rigorous analysis of the industry's historical cable fault database which provides parameters of naturally occuring cable failures (through sediment failure, for example). Together these data will provide an understanidng of the geological characteristics of key parts of the European shelf, underpinned with the statistics of active slope processes over the most recent decades. The benefits of such a synthesis to both the telecommunications and hydrocarbon industries cannot be overstated.

Geophysical Methodologies for the Characterisation of Gas Hydrate Core (HYDRAGAS) - Consortium Proposal

PROJECT DETAILS ONLY - NO DATA. Through manufacturing, and geophysically characterising the properties and distribution of a range of synthetic gas hydrate morphologies in a range of sediments in the laboratory, protocols will be established for geophysically logging natural sediment-hydrate core preserved in pressure chambers on board ship. Based on pressure cycling, geophysical behaviour responses will be determined during the start of dissociation and formation. On this basis we then propose to develop protocols to characterise and classify hydrates sampled during ODP Leg 204, significantly improving our understanding of the nature and behaviour of these sediments. This new knowledge will enhance geophysical survey data, better constrain estimates of in-situ hydrates and improve the evaluation of hydrate destabilisation on methane release and slope stability.

HOTFLO GIS - Fluid Inclusions (North Sea, Norway) Layer

PROJECT DETAILS ONLY - NO DATA. The project will determine the distribution and magnitude of Tertiary hot fluid pulses throughout the North Atlantic region in order to advance significantly the modelling of thermal history and improve our understanding of fluid migration and reservoir cementation throughout the region. Two sampling transects extend (1) from west Greenland to the northern North Sea to assess variation with proximity to the Tertiary mantle plume, and (2) near-normal, from southernmost Greenland to offshore Norway. Using fluid inclusion and vitrinite reflectance data, heat flows will be modelled which are consistent with structures inferred from seismic sections. Anomalous heat flows will be combined with other data using a GIS framework.

Combined Detrital Geochronology and Provenance Studies of Cretaceous-Paleoecene Sediments from the Faroe-Shetland Basin

PROJECT DETAILS ONLY - NO DATA. Classical provenance study techniques will be extended using Ar-Ar dating of individual detrital micas to examine the link between source uplift, erosion and sediment supply in the pivotal area west of Shetland. The work has economic significance in that it places constraints on the location of sediment entry points, intrabasinal sand body distribution, and reservoir quality, all issues of importance to the hydrocarbon industry. This scoping study is intended to test the combination of techniques in an area where the source is well characterised, and may form an analogue for rifting between Africa and South America. The importance of the work in the area is reflected by the industry backing for this project.

Developing Hydropyrolysis to Generate Molecular Biomarker Signals for Solving Key Problems in Oil Exploration where Conventional Biomarkers Fail (NER/T/S/2001/01153)

PROJECT DETAILS ONLY - NO DATA. The aim is to realise the potential of hydropyrolysis (pyrolysis assisted by high hydrogen gas pressures) as a means to provide reliable molecular fingerprints for severely biodegraded oils, contaminated cores, oil-field solids (tar mats and pyrobitumens) and to provide novel information on basin-filling history where the conventional free-biomarker approach fails. This will then facilitate rapid and accurate oil-source and oil-oil correlations to be determined for the first time in ocean-margin regions. The study will establish a firm base to exploit the commercial potential of hydropyrolysis, both in terms of oil exploration through the new correlations with bound biomarker profiles and of characteristic sedimentary organic matter as a far superior technique to py-GC-MS. Indeed, innovative experimental protocols for conducting hydropyrolysis will continue to be developed to have a prototype system ready for future exploitation.

Establishing the potential of hydropyrolysis to provide reliable molecular fingerprints for biodegraded crude oils and contaminated sediment cores

PROJECT DETAILS ONLY - NO DATA. The aim is to demonstrate the potential of hydropyrolysis (pyrolysis assisted by high hydrogen gas pressure) as a novel means to provide reliable molecular fingerprints for biodegraded oils and contaminated cores where conventional biomarker approaches fail. This will then facilitate accurate and rapid oil-source and oil-oil correlations to be determined for the first time in these situations. New experimental protocols for conducting hydropyrolysis on asphaltenes will be developed. The study will establish a firm base to exploit the commercial potential of hydropyrolysis, both in oil exploration and for characterising sedimentary organic matter as a far superior technique to pyrolysis-GC-MS through a larger industrial partner.

The Dalradian 'Snowball Earth' - Use of Stable Isotopes to Correlate Glacial Events and Neoproterozoic Stratigraphy of Scotland and Ireland

PROJECT DETAILS ONLY - Data archived in BGS Digital Archive. The 'snowball Earth' theory has been the subject of widespread media attention, particularly its lively defence by key proponent, Prof. Paul Hoffman. This period of earth history from 750 to 540 million years ago contained perhaps as many as 5 extreme events of climatic fluctuation. During the coldest of these the globe may have been entirely covered in ice. Until recent years research into the rocks of this age had focussed mainly on cold or hot desert areas of the world with very good outcrop and undeformed piles of sediments, but some of the most complete, but poorly exposed rock sections of this age are in more accessible areas such as Scotland and Ireland. Sediments are extremely difficult to date and ages of these rock sequences rely on the rare occurences of volcanic rocks. There is now the makings of a global framework of these glacial periods based on the isotopes of carbon in limestones, but without other dating evidence this can only say that the rocks are related to a glacial event, not which one. The isotopes of sulphur are constrained during this period by the rapid increase in the oxygen content of earth's oceans and atmosphere which resulted in the rapid evolution of many species and the development of vertebrate animals. This sulphur signal changed rapidly after the largest 'snowball Earth' event and recent studies suggest that this distinct signal might be globally recognisable. In Scotland and Ireland 3 glacial periods have been recognised in a seqence of rocks aged approximately 800 million years old at the base, 600 million about 75% of the way up from the base and containing 540-520 million year old vertebrate fossils close to the top. Linking the glacial periods to a particular global event in this 260 million year period has proved difficult. Combining new sulphur isotope data for the mineral pyrite from limestone and black shale rocks, with carbon isotope data and organic carbon content will allow these glacial events in Scotland and Ireland to be correlated and put into global context. This new data will place better age constraints on these rocks in Scotland and Ireland and improve the global understanding of this period of Earth history. Man's influence on the planet might have destabilised the climate system, so it is important that we understand the causes and effects of extreme climate variation in the past.

Seismic data collected from two nodal array deployments at Fuego volcano, Guatemala, December 2023 and February 2025

Seismic data collected during two nodal array deployments at Fuego volcano in December 2023 and February 2025. The data were collected by Amelia Bain, Amilcar Roca, Silvio De Angelis, Andrew Bell, and Armando Pineda for the purpose of recording seismic signals generated by the volcanic conduit at Fuego volcano, at a proximal location around 2 km from the crater. The data were collected using 9-10 instruments, which were deployed for 10 days during the two separate collection periods. The nodes were arranged in a star configuration around a central node, with a 50 m spacing. KMZ files of the deployment location and arrangement are provided along with daily miniSEED files containing the recorded seismic waveforms.

Boron geochemistry and structure of primary coral skeleton and secondary cements in Hawaiian fossil corals

The d11B and B/Ca and Raman spectra analysis of primary (unaltered) coral aragonite and secondary aragonite and calcite cements in Hawaiian fossil corals. d11B and B/Ca are influenced by CaCO3 formation pH and conditions. Raman spectra indicate CaCO3 polymorph and the full width half maxima of the Raman v1band is increased by disorder around the carbonate group in the CaCO3 lattice. Fossil samples were collected during IODP 389 (2023) and during pre-expedition sampling by submersible (https://doi.org/10.1016/j.gca.2007.07.026). Data were collected to research the formation conditions (pH and dissolved inorganic carbon) of secondary cements in fossil coral skeletons and to calculate the effect of cement inclusion on analyses of primary coral. Data were collected by Nicola Allison and Alice Sinclair.
