UKCS NDR 2D SDS seismic lines

Seismic Data from the previous (V1) National Data Repository, last updated on June 30th 2021. Seismic Header Information: NDR_2dseis_eab Navigation information for all offshore 2D seismic surveys, as reported to BEIS OPRED in seismic survey close out reports. The NSTA did not create this data set and cannot vouch for its completeness or accuracy. NDR_3dseis Survey outline information for all offshore 3D seismic surveys, including those acquired using Ocean Bottom Node and Ocean Bottom Cable techniques, as reported to BEIS OPRED in seismic survey close out reports. The NSTA did not create this data set and cannot vouch for its completeness or accuracy. Reported Seismic Data: NDR_SDS_2D_Lines Navigation information for offshore 2D seismic surveys which had Post-Stack SEG-Y data available online in the legacy NDR, the data having been reported to the NSTA via the NDR. The seismic trace data has been migrated to the current NDR service, which also holds field and pre-stack seismic data online. Seismic data may be obtained from the NDR https://ndr.nstauthority.co.uk NDR_SDS_3D_Outlines Survey outline information for offshore 3D seismic surveys, including those acquired using Ocean Bottom Node and Ocean Bottom Cable techniques, which had Post-Stack SEG-Y data available online in the legacy NDR, the data having been reported to the NSTA via the NDR.
