Abstract
Our continuing studies of annually laminated marine sediments in anoxic fjords along the west coast of Canada chronicle changes in the Holocene environment as glaciers retreated from this area about 12 ky BP, and are shedding new light on the nature and timing of abrupt "regime" shifts in coastal ocean dynamics and climate. We are refining our knowledge of the interplay between climate, ecosystems, and ocean dynamics in the northeast Pacific Ocean, with new perspectives from a diverse suite of proxy indicators including archaeological evidence from pre-historical aboriginal settlement sites, modern oceanographic and meteorological data, and landscape changes associated with recent record-breaking storms and sea surges. The Late Pleistocene and Holocene record on this coast also marks dramatic changes in sea level, with implications for the possibility of early human migration routes and glacial refugia. Excellent chronological control on Holocene paleoclimatic and paleoceanographic conditions along the British Columbia coast is now possible by complementary, yet independent, dating methods of ocean sediments in a giant 40 m piston core which is now being used as a chronological tie point for other proxy records from this area.
