GeoIndex (Offshore)

BGS Map Viewers

The offshore GeoIndex shows the range of marine geoscience data held by the BGS within the National Geoscience Data Centre (NGDC). These are primarily shallow geology and geophysics data collected as either part of regional or local mapping work, or provided to the BGS by third parties. The BGS is the Marine Environment Data and Information Network (MEDIN) Data Archive Centre (DAC) for geology, geophysics and backscatter.

GeoIndex datasets are also available to view as a Web Map Service (WMS) as are offshore marine information products.

Survey information attributes

The sample data attributes describe the information and data relating to offshore sampling activities. The activity data contains location information and metadata, plus links to scanned images of sample stations datasheets where available. The geochemical, geological, geotechnical and seabed sediment data include observations and/or measurements.

The geophysical data attributes describe information for offshore geophysical activities. The shot point layer contains only location information and metadata, whereas the survey line (seismic reflection and sonar) layers include information about the equipment types used on the line and links to scanned images of the geophysical records where the terms of use are available.

The survey data attributes describe information for coastal and marine surveys which result in the collection of data. It contains the location (outline polygon) and basic information about the survey, including the types of equipment deployed during a survey.
