(2) Final version of Full Science Proposal 864, which contains: description and illustrations of the regional stratigraphy of Pernambuco Plateau, as interpreted by the Virtual Site Survey project; site summary sheets for all proposed drill sites based on the Virtual Site Survey. (3) A complete list of all deliverables associated with this project is provided in the Data Archiving Report.

  • This digital data set contains original files of seismic reflection survey sections. Most data are within the UK Onshore area; although there are some UK near-shore and offshore (North Sea, Irish Sea) and foreign data. Most data were acquired for commercial hydrocarbon exploration and subsequently provided to BGS for use on specific projects. Some data were acquired by BGS and other public-sector bodies, e.g. BIRPS (British Institutions Reflection Profiling Syndicate), for academic research. These data are used for workstation-based interpretation. Some are kept as archive copies. There are approximately 50 tapes and 15 Exabyte cartridges. The data are mostly concentrated in areas prospective for coal, oil and gas.

  • This document dataset contains original prints, on paper, sepia or film, of seismic reflection survey sections, dating from the 1960s. Most data are within the UK onshore area; although there are some UK near-shore and offshore (North Sea, Irish Sea) and foreign data. Most data were acquired for commercial hydrocarbon exploration and subsequently provided to BGS for use on specific projects. Some data were acquired by BGS and other public-sector bodies, e.g. BIRPS (British Institutions Reflection Profiling Syndicate), for academic research. This data set is a master set; copies must be used for interpretation purposes. Documents stored rolled in tubes, approximately 10 sections per tube, approx 850 tubes. The data are mostly concentrated in areas prospective for coal, oil and gas.

  • The Seismic Line Index database stores summary administrative information about the collection of printed seismic sections, Original Seismic Sections dataset (ORIGSEISECS). This includes: details of data ownership or source, date of acquisition, purpose of survey, confidentiality, media, survey acquisition and processing parameters, and storage location in BGS. Almost all data are within the UK Onshore area; although there are some UK near-shore and offshore (North Sea, Irish Sea) and foreign data. Most data were acquired for commercial hydrocarbon exploration and subsequently provided to BGS for use on specific projects. Some data were acquired by BGS and other public-sector bodies, e.g. BIRPS (British Institutes Reflection Profiling Syndicate), for academic research. There is also scope to add relevant information about the data held in Copy Seismic Sections (COPYSEISECS) and Original Seismic Shotpoint Location Maps (ORIGSPMAPS) datasets.

  • This digital data set contains original files of seismic reflection survey location (navigation) data and dates from the late 1970s. These provide location information for the Digital Seismic Sections data set (DIGSEISECS) and some of the printed seismic sections of the Original Seismic Sections dataset (ORIGSEISECS) and Copy Seismic Sections dataset (COPYSEISECS). Most data are within the UK Onshore area; although there are some UK near-shore and offshore (North Sea, Irish Sea) and foreign data. Most data were acquired for commercial hydrocarbon exploration and subsequently provided to BGS for use on specific projects. Some data were acquired by BGS (British Geological Survey) and other public-sector bodies, e.g. BIRPS (The British Institutions Reflection Profiling Syndicate), for academic research. The data are used with the Seismic Locations and Sections Database (LOCSEC) and for workstation-based interpretation. There are approximately 20 tapes and 15 Exabyte cartridges. The data are mostly concentrated in coal, oil and gas prospecting areas.

  • This data set contains the following original data for the deep seismic reflection surveys conducted by the BGS in various parts of the UK. The data consists of observers' logs, surveyors' reports, location data tapes, field data recording tapes and processed data tapes. The processed tapes are at various stages of processing from demultiplexed field data to migrated stack (not all available for all profiles) These data are kept as archive copies. They are generally available for academic and commercial use, subject to payment of fees (and, in a few cases, the agreement of co-owners of the data rights). There are Approximately 20 files of written records and 200 tapes.

  • 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. Webpage www.bgs.ac.uk/QICS/. NERC Grant NE/H013954/1.

  • The Seismic Locations and Sections database (LOCSEC) stores digitised seismic reflection survey location and line-interpretation data. Supplementary data stored includes map projection information and rock-unit seismic velocity data. The data are grouped by interpretation project area. Location data are input from digitised seismic shotpoint (SP) or common depth point (CDP) maps, or from direct input of digital navigation data. [See: Original Seismic Shotpoint Location Maps (ORIGSPMAPS) and Digital Seismic Shotpoint Location Maps (DIGSPMAPS) datasets]. Line-interpretation data are input from digitised pick-lines on manually interpreted printed seismic sections. [See: Copy Seismic Sections dataset (COPYSEISECS)]. In-house software is used for data management and display, to perform interpretation related tasks, e.g. depth-conversion, and to merge data into X, Y, Z form for input to 3D mapping and modelling packages such as EarthVision. Data in LOCSEC may also be related to the borehole interpretations held in the Stratigraphic Surfaces Database (SSD). Almost all data are within the UK Onshore area; although there are some UK near-shore and offshore (North Sea, Irish Sea) and foreign data. Most data were acquired for commercial hydrocarbon exploration and subsequently provided to BGS for use on specific projects. Some data were acquired by BGS and other public-sector bodies, e.g. BIRPS, for academic research.

  • This document data set contains original prints, on paper, sepia or film, of seismic reflection survey location (navigation) maps. These provide the location data for the seismic sections of the Original Seismic Sections (ORIGSEISECS) and Copy Seismic Sections (COPYSEISECS) datasets. Almost all data are within the UK onshore area; although there are some UK near-shore and offshore (North Sea, Irish Sea) and foreign data. Most data were acquired for commercial hydrocarbon exploration and subsequently provided to BGS for use on specific projects. Some data were acquired by BGS and other public-sector bodies, e.g. BIRPS, for academic research. All maps are digitised upon receipt (see LOCSEC database) and then archived in this data set. (Copies used to be used for interpretation purposes but this is no longer the case.) Documents stored rolled in tubes. Approx 800 maps.

  • This database stores down-hole stratigraphic data to complement the seismic surface picks stored in the Seismic Locations And Sections Database (LOCSEC). Because these surfaces are chosen for their visibility on seismic data, they may not be directly equivalent to established BGS lithostratigraphic and/or choronstratigraphic divisions. However, the local coding system is based on and can relate to the BGS stratigraphic LEXICON. Stratigraphic picks are stored in terms of depth and seismic one-way travel time. Local borehole summary information (location, elevation, etc.) is used because both onshore and offshore boreholes are stored in this database. These data can be related to the BGS onshore borehole database by borehole registration, and to the offshore well database by DTI well-id. Additional tables (under development) provide information on hydrocarbon tests and their results. Almost all data are within the UK Onshore area; although there are some UK near-shore and offshore (North Sea, Irish Sea).
