Fourteen somewhat overlapping 1-m cores, forming a total sequence of about 10.90 metres, were retrieved from Taniente Palet bog on Isla de los Estados, Argentina. The cores were described and correlated both visually and by measuring magnetic susceptibility and loss on ignition. Twelve samples were also taken for radiocarbon dating. The results were then interpreted and compared with those from other localities in the region. Comparisons were also made on a more global scale. The sequence from Taniente Palet bog mainly consists of peat of different humification degrees with some units of minerogenic material. However, the bottom of the sequence is dominated by minerogenic material. Available radiocarbon dates show that there is an age-reversal at the bottom of the sequence, indicating re-deposition in this part. The re-deposition was interpreted as reflecting a period of increased precipitation between around 7600 and 7500 cal. B.P. The inferred precipitation increase may have caused the stream connected to the bog to flood and transport minerogenic material eroded from bedrock and/or till, as well as older peat eroded from upstream, down to Taniente Palet bog. It is possible that the precipitation increase at this time reflects a more southerly position of the southern westerlies. After around 7500 cal. B.P. the heavy precipitation is believed to have ceased. However, results indicate that changes in climatic conditions may also have occurred at around 6500, 5200, 1400 and 600 cal. B.P. Data indicate that the medieval warm period (MWP) and the little ice age (LIA) also may be registered in the sequence. The suggested climatic changes at Taniente Palet bog appear to correlate relatively well with inferred climatic changes at other localities in southern Tierra del Fuego and in the South Atlantic region. In addition, the results from Taniente Palet bog may also support the idea of a Holocene bipolar seesaw climate effect.
