A radiocarbon chronology shows that piedmont glacier lobes in the Chilean Andes achieved maxima during the last glaciation at 13,900 to 14,890, 21,000, 23,060, 26,940, 29,600, and ≥33,500 carbon-14 years before present (14C yr B.P.) in a cold and wet Subantarctic Parkland environment. The last glaciation ended with massive collapse of ice lobes close to 14,00014C yr B.P., accompanied by an influx of North Patagonian Rain Forest species. In the Southern Alps of New Zealand, additional glacial… Expand
Radiocarbon chronology of the last glacial maximum and its termination in northwestern Patagonia
Abstract We examine the timing and magnitude of the last glacial maximum (LGM) and the last glacial termination (LGT) in northwestern Patagonia, situated in the middle latitudes of South America. OurExpand
Interhemispheric synchrony of Late-glacial climatic instability as recorded in proglacial Lake Mascardi, Argentina
Several high-resolution continental records have been reported recently in sites in South America, but the extent to which climatic variations were synchronous between the northern and southernExpand
Interhemispheric linkage of paleoclimate during the last glaciation
Combined glacial geologic and palynologic data from the southern Lake District, Seno Reloncavi, and Isla Grande de Chiloe in middle latitudes (40°35’–42°25’S) of the Southern Hemisphere Andes suggestExpand
Climatic inferences from glacial and palaeoecological evidence at the last glacial termination, southern South America
There is uncertainty about the interhemispheric timing of climatic changes during the last glacial-interglacial transition. Different hypotheses, relying on different lines of evidence, pointExpand
Interhemispheric climate links revealed by a late-glacial cooling episode in southern Chile
Pollen records from three sites in the Lake District of southern Chile are reported, from which it is inferred conditions similar to modern climate between about 13 and 12.2 14C kyr before present (bp), followed by cooling events at about 12.3 and 11.4‬C‬kyr, supporting the idea that interhemispheric linkage through the atmosphere was the primary control on climate during the last deglaciation.

Late Quaternary glacial history in the Encierro Valley, northern Chile (29°S), deduced from 10Be surface exposure dating
Abstract The Late Pleistocene glacial and climate history in the dry Central Andes is not well known so far, mainly because of the lack of suitable material for radiocarbon dating. In order toExpand
40Ar/39Ar evidence for early deglaciation of the central Chilean Andes
Spatial variability of deglaciation and warming since the last glacial maximum is critical for relating hemispheric or regional climate-forcing mechanisms to global orbitally-induced insolationExpand
Palaeoecological constraints on late Glacial and Holocene ice retreat in the Southern Andes (53°S)
Late Glacial to Holocene ice retreat was investigated along a 120 km long fjord system, reaching from Gran Campo Nevado (GCN) to Seno Skyring in the southernmost Andes (53°S). The aim was to improveExpand
The deglaciation of the Americas during the Last Glacial Termination
Abstract This paper reviews current understanding of deglaciation in North, Central and South America from the Last Glacial Maximum to the beginning of the Holocene. Together with paleoclimatic andExpand
Deglacial and postglacial climate history in east-central Isla Grande De Chiloé, Southern Chile (43°S)
Palynologic and stratigraphic data from Laguna Tahui (42°50′S, 73°30′W) indicate cool–temperate and humid conditions there between 14,000 and 10,000 14C yr B.P., followed by warmer andExpand


Pleistocene glaciation in the southern Lake District of Chile
Relative-age criteria permit deposits of successive Andean glacier advances in the southern Lake District of Chile to be divided into four mappable drift sheets, the oldest two of which overlieExpand
Evidence for massive discharges of icebergs into the North Atlantic ocean during the last glacial period
SEDIMENTS in the North Atlantic ocean contain a series of layers that are rich in ice-rafted debris and unusually poor in foraminifera1. Here we present evidence that the most recent six of theseExpand
Irregular glacial interstadials recorded in a new Greenland ice core
THE Greenland ice sheet offers the most favourable conditions in the Northern Hemisphere for obtaining high-resolution continuous time series of climate-related parameters. Profiles of 18O/<16O ratioExpand
Intensity, gradients and reversals in late glacial environmental change in east-central north America
Abstract Radiocarbon-dated pollen sites from the Allegheny Plateau (east) and the Till Plains (west) document significant vegetational and climatic change between 15,000 and 9000 14 C BP south of theExpand
Late Glacial Stage and Holocene Tropical Ice Core Records from Huascar�n, Peru
Two ice cores from the col of Huascar�n in the north-central Andes of Peru contain a paleoclimatic history extending well into the Wisconsinan (W�rm) Glacial Stage and include evidence of the Younger Dryas cool phase, implying that a strong warming has dominated the last two centuries. Expand
The magnitude and rapidity of the climate change marking the end of the Pleistocene in the mid-latitudes of South America

Correlations between climate records from North Atlantic sediments and Greenland ice
OXYGEN isotope measurements in Greenland ice demonstrate that a series of rapid warm-cold oscillations—called Dansgaard–Oeschger events—punctuated the last glaciation1. Here we present records of seaExpand
Late quaternary vegetation of southern Isla Grande de Chiloé, Chile
Late-glacial-Holocene forest history of southern Isla Chiloe (latitude 43°10′ S) was reconstructed on the basis of pollen analysis in three profiles (Laguna Soledad, Laguna Chaiguata, Puerto Carmen).Expand
Comparison of oxygen isotope records from the GISP2 and GRIP Greenland ice cores
RECENT results1,2 from the Greenland Ice-core Project (GRIP) Summit ice core suggest that the climate in Greenland has been remarkably stable during the Holocene, but was extremely unstable for theExpand
The abrupt termination of the Younger Dryas climate event
PREVIOUS studies on two deep Greenland ice cores have shown that a long series of climate oscillations characterized the late Weichselian glaciation in the North Atlantic region1, and that the lastExpand
