The locations of coastal British Columbia offshore oil and gas seismic profiles. There has not been any seismic done in the Queen Charlotte Basin since 1972. There currently exists a moreatorium on Oil and Gas exploration so there are no plans to do any more until the moratorium is lifter. The seismic lines in this data layer are surveys which were done over 45 years ago, in single passes. The attribute data for the polylines refers to interpretations done in 1988, which are still accessible via the web-links.
