Glacier and terrestrial ecosystem evolution in the Chilotan archipelago sector of northwestern Patagonia since the Last Glacial Termination
(2022)
We examine the glacier, terrestrial ecosystem, and climate evolution since the Last Glacial Termination (T1) based on glacial sediments/landform assemblages and palynological data from the Chilotan archipelago (41°30′S-43°30′S), ...
Radiocarbon chronology of the last glacial maximum and its termination in northwestern Patagonia
(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 ...
Abrupt changes in high-latitude nutrient supply to the Atlantic during the last glacial cycle
(Geological Soc Amer, INCBoulder, 2012)
The supply of nutrients to the low-latitude thermocline is largely controlled by intermediate-depth waters formed at the surface in the high southern latitudes. Silicic acid is an essential macronutrient for diatoms, which ...
An improved land biosphere module for use in the DCESS Earth system model (version 1.1) with application to the last glacial termination
(2017)
Interactions between the land biosphere and the atmosphere play an important role for the Earth's carbon cycle and thus should be considered in studies of global carbon cycling and climate. Simple approaches are a useful ...

Clocking the arrival of Homo sapiens in the Southern Cone of South America
(Kerns Verlag, 2018)
The Southern Cone of South America (Argentina, Chile, Uruguay and SoutheasternBrazil) was the last continental mass colonized by humans. Until recently, thediscussion about the peopling of the Americas revolved around the ...
Centennial to millennial-scale changes in oxygenation and productivity in the Eastern Tropical South Pacific during the last 25,000 years
(Elsevier, 2015)
Oxygen minimum zones (OMZ) have expanded in all tropical oceans during the last 50 years resulting in habitat contraction and considerable changes in marine biogeochemistry. However, for a better understanding of the OMZ ...
Geophysical evidence of multiple glacier advances in Lago Fagnano (54°S), southernmost Patagonia
(Elsevier, 2010-05)
The Island of Tierra del Fuego, at the southernmost extreme of Patagonia, is located in one of the most extensively glaciated areas of the Southern Hemisphere outside Antarctica during the late Pleistocene. The Lago Fagnano ...
Holocene glacier history of northeastern Cordillera Darwin, southernmost South America (55°S)
(2022)
In the Cordillera Darwin, southernmost South America, we used 10Be and 14C dating, dendrochronology, and historical observations to reconstruct the glacial history of the Dalla Vedova valley from deglacial time to the ...
Paleo±Dust: quantifying uncertainty in paleo-dust deposition across archive types
(2024)
Mineral dust aerosol concentrations in the atmosphere varied greatly on glacial–interglacial timescales. The greatest changes in global dust activity occurred in response to changes in orbital parameters (which affect dust ...
