Alloway, B. V.; Almond, P. C.; Moreno Moncada, Patricio; Sagredo, E.; Kaplan, M. R.; Kubik, P. W.; Tonkin, P. J. (Elsevier, 2018-06)South Westland, New Zealand, and southern Chile, are two narrow continental corridors effectively confined between the Pacific Ocean in the west and high mountain ranges in the east which impart significant influence over ...

Moreno Moncada, Patricio (2004)A pollen record from Lago Condorito (41 °45′S, 73 °07′W) shows prominent vegetation and climate changes at millennial time-scales, superimposed on multimillennial trends in temperature and westerly activity in northwest ...

Alloway, B. V.; Pearce, N. J. G.; Villarosa, G.; Outes, V.; Moreno Moncada, Patricio (Nature, 2015)Within the volcanological community there is a growing awareness that many large-to smallscale, point-source eruptive events can be fed by multiple melt bodies rather than from a single magma reservoir. In this study, glass ...

Moreno Moncada, Patricio; Vilanova, I.; Villa Martínez, R.; Dunbar, R. B.; Mucciarone, D. A.; Kaplan, M. R.; Garreaud Salazar, René; Rojas, M.; Moy, C. M.; De Pol-Holz, R.; Lambert, F. (Nature Publishing Group, 2018)The Southern Westerly Winds (SWW) are the surface expression of geostrophic winds that encircle the southern mid-latitudes. In conjunction with the Southern Ocean, they establish a coupled system that not only controls ...

Moreno Moncada, Patricio; Alloway, B.; Villarosa, G.; Outes, V.; Henríquez, W.; Pol-Holz, R. de; Pearce, N. (Geological Soc Amer, 2015)Volcan Chaitan (southern Chile, similar to 43 degrees S) initiated an historically unprecedented eruption in A.D. 2008, surprising the local inhabitants, Chilean and Argentine authorities, and the geologic community. ...

Vidal, Marcela A.; Ibáñez, Soledad; Moreno Moncada, Patricio; Poulin, Elie (Wiley-Blackwell, 2016)Pleistocene glaciations produced significant increases in continental ice cover in polar and mid-latitude temperate areas, sea-level declines and shifts and reshuffling of biomes, all of which promote either isolation, ...

Villa Martínez, Rodrigo; Moreno Moncada, Patricio (ELSEVIER, 2007)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 ...

Jara, Ignacio A.; Newnham, Rewi M.; Vandergoes, Marcus J.; Foster, Courtney R.; Lowe, David J.; Wilmshurst, Janet M.; Moreno Moncada, Patricio; Renwick, James A.; Homes, Aline M. (Wiley & Sons, 2015)We present a 16 000-year vegetation and climate reconstruction from pollen and plant macrofossil records obtained at a small alpine lake in South Island, New Zealand (41 degrees S). The expansion of lowland forest taxa ...

Hajdas, Irka; Bonani, Georges; Moreno Moncada, Patricio; Ariztegui, Daniel (Academic Press Inc., 2003)Variability of atmospheric 14C content often complicates radiocarbon-based chronologies; however, specific features such as periods of constant 14C age or steep changes in radiocarbon ages can be useful stratigraphic ...
-
Moreno Moncada, Patricio; Denton, George H.; Moreno, Hugo; Lowell, Thomas V.; Putnam, Aaron E.; Kaplan, Michael R. (Elsevier, 2015)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. Our data indicate that the main ...

Alloway, Brent V.; Moreno Moncada, Patricio; Pearce, Nick J. G.; De Pol-Holz, Ricardo; Henríquez, William I.; Pesce, Oscar H.; Sagredo, Esteban; Villarosa, Gustavo; Outes, Valeria (Wiley, 2017)We describe the stratigraphy, age and correlation of a prominent tephra marker, named Lepue Tephra, extensively distributed in north-western Patagonia. Lepue Tephra is well dated at c. 11 000 cal a BP from numerous lake ...

Jara, Ignacio A.; Moreno Moncada, Patricio (Elsevier, 2012)We present detailed pollen and charcoal records from Lago Pichilafquén (~41°S) to decipher the effects of climate change and varying disturbance regimes on the composition and structure of the vegetation on the Andean ...
