A high-resolution marine palynological record from the central mainland coast of British Columbia, Canada: evidence for a mid-late Holocene dry climate interval
Sediments collected in a 12-m long core (VEC02A04) obtained from Frederick Sound in the Seymour–Belize Inlet Complex of British Columbia were deposited between ca. 4540 cal. yr BP and ca. 1090 cal. yr BP in primarily dysoxic conditions. The sediments are characterized by alternating intervals of fin...
