Description :
The sea-level history of mainland British Columbia and eastern Vancouver Island is very different from that of the Queen Charlotte Islands and wester Vancouver Island. The patterns of sea-level change are attributed to complex isostatic response to downwasting and retreat of the late Wisconsin Cordilleran Ice Sheet, to transfers of water from melting ice sheets to oceans, and to plate interactions on the continental margin. Late Pleistocene and early Holocene crustal movements were dominantly isostatic. Although the recent regression on the outer coast likely is due, at least in part, to tectonic uplift, some late Holocene sea-level change in this area may be either eustatic in nature or a residual isostatic response to deglaciation.
