Description
Summary:The historical seal populations at King George Island, Antarctica, for the past 1,500 years, have beenauthor='Ann' time='20040309T120345+0100' data='were' estimated from the seal-hair abundance, bio-element concentrations, total organic carbon (TOC) and total nitrogen (TN) in one terrestrial sediment sequence influenced by seal excrement. Prior to human interference, the seal populations exhibited dramatic fluctuations with two peaks during 750-500 and 1400-1100 years before present (yr B.P.) and two troughs during 1100-750 and 500-200 yr B.P. A tentative comparison of the seal populations and historical climates in the Antarctic Peninsula region suggests that the seal populations may be linked to climate-related factors such as sea-ice coverage and atmospheric temperature.
