This dataset contains data from a river multibeam and seismic survey which took place in 2013 and 2014 at scour sites within the Brahmaputra river basin in Bangladesh. The survey was carried out as part of a joint project between the Universities of Birmingham, Southampton and Exeter. "The sedimentology of fluvial megascours" was a scientific research project funded by NERC. The purpose was to collect the data necessary to validate the first generic numerical model of scour zone stratigraphy that will be widely applicable to a broad range of large rivers. River bed bathymetry data were collected using a multibeam echosounder. Sub bottom seismic profiling data were collected using a surface tow boomer and chirp system. Technical details of the survey are contained in the cruise report of the survey which comprises part of the metadata. Some of the data has been accepted for a publication in the journal 'Sedimentology' which will be published in 2018 with the title 'The Sedimentology of channel confluences'.
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.

Low-resolution Paleogene bulk sediment stable oxygen and carbon isotope data from IODP Expedition 369, Sites U1514 and U1516 in the SE Indian Ocean.
This dataset contains numerical model output of a morphodynamic and sedimentological simulation of a large river confluence based loosely on the Jamuna-Ganges junction in Bangladesh. The work was carried out as part of a joint project between the Universities of Birmingham, Southampton and Exeter. "The sedimentology of fluvial megascours" was a scientific research project funded by NERC. One aspect of the project was to undertake numerical simulations (the data described here) with which to compare with river bed bathymetry data (collected using a multibeam echosounder) and sub bottom seismic profiling data (collected using a surface tow boomer and chirp system). The data has been accepted for a publication in the journal 'Sedimentology' which will be published in 2018 with the title 'The Sedimentology of channel confluences'.
The dataset consists of: (1) Listing of full site survey package of geophysical data held in the IODP Data Bank in support of proposal 864. Details of how to obtain existing freely available or commercial proprietary data are included. (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.
The dataset contains carbon dioxide and methane emissions, as well as resorufin production (as a proxy for microbial metabolic activity) and dissolved oxygen concentrations, resulting from laboratory incubation experiments of streambed sediments. The sediments were collected from the upper 10 centimetres of the streambed in the River Tern and the River Lambourn in September 2015, with three samples collected from each river. These samples were collected from three areas: silt-dominated sediment underneath vegetation (fine), sand-dominated sediment from unvegetated zones (medium) and gravel-dominated sediment from unvegetated zones (coarse). The sediment was used in laboratory incubation experiments to determine the effect of temperature, organic matter content, substrate type and geological origin on streambed microbial metabolic activity, and carbon dioxide and methane production. The work was carried out as part of a Natural Environment Research Council (NERC) funded PhD (NERC award number 1602135). The work was also part funded through the Seventh Framework Programme (EU grant number 607150).

The data is provided as a single spreadsheet containing geochemical information from three volcanoes (Antuco, Chile; Jocotitlan, Mexico; Montserrat), all of which have been affected by major debris avalanches. The data was collected in order to investigate the long-term evolution of these volcanic systems. In addition, a single worksheet is provided of a summary database of published examples of volcanic debris avalanches. The geochemical data include bulk-rock XRF and ICP-MS data, Sr and Pb isotope measurements, and glass analyses for the Montserrat samples, along with site information for Antuco and Jocotitlan. Additional published analyses for Montserrat is availabile in published papers, as detailed in the spreadsheet.
Collection of data from the PhD Thesis 'Development of coupled processes numerical models of tracer, colloid and radionuclide tranpsort in field migration experiments', submitted as part of the RATE HydroFrame WP5. This collection of data includes blank model files in COMSOL Multiphysics and PHREEQC, as described in the PhD thesis. Also included in this data package are different spreadsheets with model outputs from the model files that describe the transport of conservative tracers, colloids and radionuclides in experiments carried out at the Grimsel Test Site, Switzerland as part of the Colloid Radionuclide and Retardation (CRR) and the Colloid Formation and Migration (CFM) experiments (www.grimsel.com).
