AbstractThe principal objective of the 2010 Canadian Polar Margin Seismic Reflection and Refraction Survey was to acquire multichannel seismic reflection and refraction data along positions that serve to establish sediment thicknesses and acquire bathymetric soundings along Canadian and US western Arctic continental margins. Strategic ship track lines were established to complement existing data to meet UNCLOS Extended Continental Shelf (ECS) sediment thickness, bathymetric and scientific objectives. In addition to the geoscience program, ice observations were acquired to groundtruth remotely sensed data. Seismic system calibration experiments were conducted to quantify sound signal intensity levels produced by the sound source. 3673 line-km of high quality multichannel seismic reflection data were acquired in addition to seismic refraction data recorded from 34 sonobuoy deployments. 9500 line-km of single beam bathymetry data were obtained plus 61 helicopter spot soundings. In collaboration the United States Coast Guard Cutter Healy, similar amounts of multibeam bathymetric and chirp subbottom profiler data were acquired.
Summary(Plain Language Summary, not published)
The Geological Survey of Canada acquired more than 26,000 line-km of multi-channel seismic reflection data in support of extended continental shelf mapping in the western Arctic Ocean, the Labrador Sea and the Scotian margin. In the Arctic, these data were acquired jointly with the United States extended continental shelf program. This open file represents a release of these data in high resolution image format.
