Abstract
The 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.
