Gravity - CSV Point Data - CSV Données ponctuelles
Gravity anomaly data show variations in the gravity field caused by lateral variations in the density of the Earth's crust and upper mantle that reflect variations in composition and thickness. Systematic gravity mapping began in Canada in 1944 and is ongoing. All data are tied to the International Gravity Standardization Network 1971. Local gravity anomalies result from the juxtaposition of relatively high- and low-density rock types. Longer wavelength anomalies such as the gravity low over the Cordillera and the relative gravity high over oceanic crust largely reflect variations in the thickness of the crust.
