Holocene glacier behavior around the northern Antarctic Peninsula and possible causes
(Elsevier, 2020)
We obtained 49 new Be-10 ages that document the activity of the former Northern Antarctic Peninsula Ice Sheet, and subsequently the James Ross Island Ice Cap and nearby glaciers, from the end of the last glacial period ...
The impacts of deglacial meltwater forcing on the South Atlantic Ocean deep circulation since the Last Glacial Maximum
(2014-09-17)
A NCAR-CCSM3 (National Center for Atmo- spheric Research – Community Climate System Model ver- sion 3) state of-the-art transient paleoclimate simulation with prescribed freshwater inflows is used to investigate the changes ...
Refinement of the tephrostratigraphy straddling the northern Patagonian Andes (40–41°S): new tephra markers, reconciling different archives and ascertaining the timing of piedmont deglaciation
(2022)
We describe the stratigraphy, age, geochemistry and correlation of tephra from west to east across the northern Patagonian Andes (c. 40–41°S) with a view to further refining the eruptive history of this region back to the ...
The hydrological response of Northeastern Brazil during last deglaciation
(Instituto de Geociências - USPSão Paulo, 2014)
Paleociimate proxy and numerical modelling data suggest prominent change in precipitation over lowland tropical South America during last deglaciation. The hydrography of Northeastem Brazil under such change in precipitation, ...
Deglaciation of the Cordillera Blanca (Peru) through the Schmidt Hammer exposure dating (shed)
(International Permafrost AssociationPE, 2019)
This study presents the first results on the deglaciation of the Cordillera Blanca (Perú), concretely in the Nevado Hualcán (9º,12 S; ̴77º31’ W; 6122 m), through the Schmidt Hammer Exposure Dating (SHED). Taking as reference ...
Glacier evolution of nevado Huaytapallana since the Little Ice Age, applying geomorphological records
(Universidad de Ingeniería y TecnologíaPE, 2019-08)
The aim of this work has been to assess the deglaciation of Nevado Huaytapallana (11º53'S, 75º, 03'W, 5558 m), the summit of a mountain range that extends along 18 km, with NW-SE direction in the Amazonian slope of the ...
Deglacial and postglacial climate history in east-central Isla Grande de Chiloé, southern Chile (43°S)
(2004)
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 and drier-than-present conditions between ...
Deglacial changes of the southern margin of the southern westerly winds revealed by terrestrial records from SW Patagonia (52°S)
(Elsevier, 2012)
Much of the ongoing discussion regarding synchrony or bipolar asynchrony of paleoclimate events has
centered on the timing and structure of the last glacial termination in the southern mid- latitudes, in
particular the ...
