  • The data is from four three-component broadband seismometers deployed along the lower east rift zone during the 2018 Kilauea eruption for four months. The instruments were deployed towards the end of July before the eruption ceased, and were placed in locations that would complement the existing USGS seismic network.

  • In 1992, BIRPS joined with the Indonesian Marine Geological Institute to record two long multichannel normal-incidence reflection profiles, one of which is DAMAR, the other TIMOR, and one short profile (API) close to the volcano Gunung Api. The survey provides a modern analogue to tectonics hypothesized to have occurred across the Iapetus suture zone of northern England 450-400 Ma. The Banda Arc of Indonesia near the island of Timor is widely recognized as the premier example of the active subduction of continental crust and lithosphere beneath oceanic lithosphere. The crossing of a modern island arc and close passage to active volcanoes was intended to image reflections associated with magma in the crust and uppermost mantle.

  • This is a subset of the seismic GI gun data recorded on the CHIMNEY JC152 cruise in 2017 (further information and nomenclature in Bull et al. 2018). Data were recorded on Ocean Bottom Seismic Receivers 1 and 19, and shots were selected to maintain offsets of approximately 200m, with a wide but uneven azimuth distribution. This was done to study azimuthal attenuation anisotropy for near-vertically travelling P-waves. The data are in SEGY format, with file names in the form: Rec*_**_***_nmo.sgy where * is receiver number ** is GI for the GI gun source and Dura for the surface sparker source *** is X for X component, Y for Y component, Z for Z component and H for hydrophone.

  • The data result from a cooperative project between the U.K., U.S., Germany, Spain, and Portugal. This 2013 seismic experiment surveyed the Galicia Bank region off Iberia with the RV Marcus Langseth. The goal was to collect 3D seismic reflection data specifically designed to reveal the 3D structures generated during the rifting of the Galicia margin and to study the rifted continental to oceanic crust transition in the Deep Galicia Margin west of Spain. The data correspond to a 68.5km x 20 km volume down to 14s TWT with a nominal inline spacing of 6.25 m and a cross-line spacing of 50m, including 800 inlines and 5500 cross-lines.

  • MONA LISA (Marine and Onshore North Sea Acquisition for Lithospheric Seismic Analysis) seismic data was acquired by BIRPS (the British Institutions Reflection Profiling Syndicate) across the Ringkobing-Fyn High of the central North Sea were designed to study the crust near a hypothesized Caledonian age triple junction associated with the colliding continental crust of Laurentia, Avalonia (Gondwanaland) and Baltica. The specific target was the eastward continuation of the Caledonian Front (Iapetus Suture), as previously recognised on NEC (North East Coast line), MOBIL (Measurements over Basins to Image Lithosphere), NSDP (North Sea Deep Profile) and BABEL (Baltic and Bothnian Echoes from the Lithosphere) profiles, in northern Europe. 1112 km of data were acquired, recorded to 26 s two-way time.

  • WESTLINE was acquired by BIRPS (the British Institutions Reflection Profiling Syndicate). The seismic data image the faulted conjugate margins of the Rockall Trough and the intrabasinal sediments. The seismic data were shot to 18 s two-way time along a single 450 km-long transect.

  • The UK Onshore Geophysical Library was established in 1994 in conjunction with the Department of Trade and Industry (DTI) and the UK Onshore Operators Group (UKOOG). The Library manages the archive and official release of seismic data recorded over landward areas of the UK. By agreement with the DTI and HMSO, the Library operates as a registered charity, funded by revenues raised from data sales and donations, with the long term objective of bringing all available UK onshore digital seismic data into secure archival storage, whilst providing efficient access to all interested parties. BGS has access to the data at cost of copying only for science budget work. Data index on the BGS Geoscience Data Index.

  • BIRPS (the British Institutions Reflection Profiling Syndicate) acquired almost 650 km of offshore seismic data and 300 km of onshore seismic data over the Chicxulub impact crater. The data were recorded to 18 s two-way time.

  • The 3D multi channel seismic data were acquired as part of a collaborative investigation into models of magmatic segmentation between the Scripps Institute of Oceanography and BIRPS (the British Institutions Reflection Profiling Syndicate). The 3D EPR (East Pacific Rise) ARAD (Anatomy of a Ridge Axis Discontinuity) EW9707 cruise was undertaken in September and October 1997 to provide both refelction and wide-angle seismic data for the study of the overlapping spreading centre (OSC) at 9 degrees 3 minutes N on the East Pacific Rise. The data were acquired with a single source and a single streamer with a nominal line spacing of 100 m. The 3D-EPR ARAD survey was a joint NERC/NSF (US National Science Foundation) funded project and the copyright for this survey is held jointly. Reference: Bazin, S. Harding, AJ. et al.

  • This is Seistec Boomer data acquired on Lake Tana. If not familiar with this variant of standard Boomer, it has a line-in-cone.
