Abstract

Vegetation and climate over approximately the past 13,000 yr are reconstructed from fossil pollen in a 9.4 m mire section at Caleta Robalo on Beagle Channel, Isla Navarino. Fifty surface samples reflecting modern pollen dispersal serve to interpret the record. Comparisons drawn with records from Antarctica, New Zealand, Tasmania, and the subantarctic islands demonstrate broadly uniform conditions in the circumpolar Southern Hemisphere. The influences of continental and maritime antarctic air masses were apparently considerable in Tierra del Fuego during cold late-glacial time, whereas Holocene climate was largely regulated by interplay between maritime polar and maritime tropical air
