Abstract
One hundred relevelled segments, scattered over Nova Scotia, and mean sea-level trends revealed by the regression analysis of tide-gauge data at three locations in the area, were used to evaluate the recent vertical crustal movements. A technique based on the determination of a smooth velocity surface was chosen to process the data. Even though the configuration of the segments is somewhat adverse, it can be concluded that the results, indicating a fast subsidence — of the order of 50 cm per century — in the central part of Nova Scotia, are realistic. The experiment has also proved that the velocity-surface technique is a useful tool for studying vertical crustal movements.
