Abstract
A radiocarbon-dated pollen diagram of a 1-m-deep peat section covering the time between ca. 4400 and ca. 800 BP is presented from Brøggerhalvøya, Spitsbergen. Local changes in vegetation and environment are deduced from palynology, lithology, and chronology; possible regional climatic changes are discussed. The main results are as follows: (1) ca. 4400-ca. 2450 BP: the wetness of the peat-forming vegetation increased in three phases, possibly due to cooling of the climate. (2) ca. 2450–ca. 800 BP: the peat-forming vegetation was dry, probably due to formation of erosion gullies at ca. 2450 BP. (3) After ca. 800 BP the record stops, probably due to progressive erosion of the gully adjacent to the studied site, preventing peat growth.
