5203 |a"The first vertical movement map of Canada was compiled from 5046 relevelled segments, from 39 pairs of water gauge data and from trends at 47 tide gauge stations. The country was divided into 9 regions and polynomial surfaces of order 2, 3 and 4 were calculated by the method of least squares for each region to obtain representations of the recent vertical movements. Vertical control for the solution over a region was provided by tide gauge trends, calculated from monthly means; by predicted values obtained from a solution for a strip connecting the Pacific with the Gulf of St. Lawrence and based upon 16 tide gauge trends and 2104 relevelled segments; and by predicted values available from an earlier determination for the overlapping region. The computations commenced at the east and west coasts and progressed inwards to the central region. The final solutions for the various orders of surface were compiled from the 9 overlapping solutions. The 3rd order surface represents the available data best. This solution is in agreement with the results and models presented by other investigators for uplift in the Yukon and northern B.C., for uplift in the Great Lakes region, and for subsidence in the Bay of Fundy. Subsidence in the Prairies, based on the presently available limited dataset requires further investigation"--Abstract.
