Coal Authority Seismic Survey Data.

This data set is an archive of original data for the seismic reflection surveys conducted by the National Coal Board (NCB) and its successor, British Coal Corporation (BCC). The data consists of observers' logs, surveyors' reports, (some 3000 files of written records), location data, field data records and processed data. The processed data are at various stages of processing from demultiplexed field data to migrated stack (not all available for all profiles). The data were originally recorded on over 13000 tapes and have been transcribed to more modern media in Tape Image Format (TIF/ARC) to retain the tape block integrity. These data are owned by the Coal Authority (CA), as successor to the NCB and BCC, BGS being the custodian under an agreement with the CA. The Coal authority surveys cover various areas in the UK, shot and processed or reprocessed between 1973-94. There is at an initial estimate half a terabyte of Coal Authority data. The seismic data will be stored as standard format SEGY files which can be read by a variety of software packages designed to manipulate seismic data. Catalogue available.
