The Southern Westerly Winds (SWW) are the surface expression of geostrophic winds that encircle southern mid-latitudes. In conjunction with Ocean, they establish a coupled system not only controls climate in third world, but is also closely connected to position Intertropical Convergence Zone and CO2 degassing from deep ocean. Paradoxically, little known about their behavior since last ice age relationships mid-latitude glacier history tropical variability. Here we present lake sediment...
Abstract We report pollen and charcoal records from Vega Ñandú (∼ 51°0′S, 72°45′W), a small mire located near the modern forest-steppe ecotone in Torres del Paine National Park, southern Chile. The record shows an open landscape dominated by low shrubs herbs between 12,600 10,800 cal yr BP, under cold relatively humid conditions. Nothofagus experienced frequent, large-amplitude oscillations 6800 indicating recurrent transitions shrubland/parkland environments, warm highly variable moisture A...
Abstract Central Chile (32–35°S) lies at the northern border of strong Westerly influence and thus exhibits a steep precipitation gradient. Therefore, palaeoclimatic archives in region are suitable for detecting past moisture changes. The study Laguna Aculeo (33°50'S, 70°54'W) presents multiproxy Holocene lake record including sedimentology, geochemistry, mineralogy, pollen, diatoms, radiocarbon dating (17 dates). Results indicate an arid early to mid-Holocene period (about 9500–5700 cal yr...

Abstract. Few studies have examined in detail the sequence of events during last glacial termination (T1) core sector Patagonian Ice Sheet (PIS), largest ice mass Southern Hemisphere outside Antarctica. Here we report results from Lago Edita (47°8′ S, 72°25′ W, 570 m a.s.l.), a small closed-basin lake located valley overridden by eastward-flowing Andean glaciers Last Glacial Maximum (LGM). The record shows glaciolacustrine sedimentation until 19 400 yr BP, followed organic and mosaic...
Abstract We report multiproxy analyses of a sediment core obtained from Laguna Aculeo that spans the past 7500 years. (33°50′S, 70°55′W) is one few natural inland lakes located in Mediterranean zone Central Chile, near northern margin influence southern westerlies. The record shows elevated pollen counts halophytes and seasonally drying lake basin prior to 5700 cal yr B.P., indicating severe aridity warmer-than-present conditions. This was followed by establishment fresh-water lake, along...
Two Holocene tephras encountered in outcrops, cores and trenches bogs, lake the area around Cochrane, southern Chile, are identified (based on their age, tephra glass color morphology, mineralogy, both bulk chemistry) as H1 derived from Hudson volcano, MEN1 Mentolat volcano. New AMS radiocarbon ages indicate systematic differences between those determined (MEN1=7,689 H1=8,440 cal yrs BP) surface deposits (MEN1=7,471 H1=7,891 BP), with being somewhat older. layers range 8 to 18 cm thick,...
