| Résumé | (disponible en anglais seulement)
The 2009 Canadian Polar Margin Seismic Reflection and Refraction Survey was a tremendous success, in large part due to the experience and innovation of its
technical staff. The principal objective was to acquire multichannel seismic reflection and refraction data along positions that serve to establish sediment thicknesses along Canadian and US western Arctic continental margins. Secondary objectives
included bathymetric sounding at specific locations along this margin to validate bathymetric data acquired by other means (e.g. satellite altimetry) in order to establish baseline information such as the 2500 m contour position. Strategic ship track
lines were established to complement existing data to meet UNCLOS and scientific objectives. In addition to the geoscience program, samples and measurements were taken of Arctic Ocean water for chemical and physical oceanographic studies. Seismic
system calibration experiments were also conducted to quantify sound signal intensity levels produced by the seismic system. 4069 line-km of high quality multichannel seismic reflection data were acquired, in addition to seismic refraction data
recorded from 51 sonobuoys deployments. 8355 line-km of single beam bathymetry were achieved, in addition to 177 helicopter spot soundings. The physical/chemical oceanographic portion of the program resulted in 7 rosette water sample stations seven
CTD/SVP casts and 72 XCTD casts. |
| Sommaire | (Résumé en langage clair et simple, non publié)
La Commission géologique du Canada a acquis plus de 26 000 km linéaires de données multibandes de sismique-réflexion pour appuyer la
cartographie du plateau continental étendu dans l'ouest de l'océan Arctique, la mer du Labrador et la marge néo-écossaise. Dans l'Arctique, ces données ont été acquises conjointement avec l'Extended Continental Shelf Program (programme du plateau
continental étendu) des États-Unis. Ce dossier ouvert donne accès à ces données en format d'image à haute resolution. |
