The PMIP4 contribution to CMIP6-Part 4: Scientific objectives and experimental design of the PMIP4-CMIP6 Last Glacial Maximum experiments and PMIP4 sensitivity experiments
(2017)
The Last Glacial Maximum (LGM, 21 000 years ago) is one of the suite of paleoclimate simulations included in the current phase of the Coupled Model Intercomparison Project (CMIP6). It is an interval when insolation was ...
Changes in the intermediate water mass formation rates in the global ocean for the Last Glacial Maximum, mid-Holocene and pre-industrial climates
(AMER GEOPHYSICAL UNIONWASHINGTON, 2012)
The paleoclimate version of the National Center for Atmospheric Research Community Climate System Model version 3 (NCAR-CCSM3) is used to analyze changes in the water formation rates in the Atlantic, Pacific, and Indian ...
First Ams Radiocarbon Direct Dates on Bones from Extinct Megafauna in Camet Norte (Santa Clara Del Mar, Buenos Aires Province, Argentina)
(Asociacion Paleontologica Argentina, 2018-02)
The first AMS radiocarbon dates from the Camet Norte fossil site (Buenos Aires Province, Argentina) range from ca. 28,700 cal. BP to 27,500 cal. BP. The age of the site fits well with results of previous studies, but the ...
A First Intercomparison of the Simulated LGM Carbon Results Within PMIP-Carbon: Role of the Ocean Boundary Conditions
(John Wiley & Sons Inc., 2021-10)
Model intercomparison studies of coupled carbon-climate simulations have the potential to improve our understanding of the processes explaining the (Formula presented.) drawdown at the Last Glacial Maximum (LGM) and to ...
Geomorphologic and Glacial Evolution of the Cachapoal and southern Maipo catchments in the Andean Principal Cordillera, Central Chile (34°-35° S)
(Servicio Nacional de Geología y Minería (SERNAGEOMIN), 2019)
We present here a reconstruction of the post late Miocene landscape evolution of the western slope of the Andean Cordillera Principal near 34°20’ S. We base our analysis on the available geological information, a morphological ...
Timing and extent of late pleistocene glaciation in the arid central andes of Argentina and Chile (22°-41°s)
(Universidad de La Rioja, 2017-07)
The arid Central Andes are a key site to study changes in intensity and movement of the three main atmospheric circulation systems over South America: the South American Summer Monsoon (SASM), the Westerlies and the El ...
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 ...
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 ...
Mitochondrial population genomics supports a single pre-Clovis origin with a coastal route for the peopling of the Americas
(CELL PRESS, 2008)
It is well accepted that the Americas were the last continents reached by modern humans, most likely through Beringia. However, the precise time and mode of the colonization of the New World remain hotly disputed issues. ...
