Lead Isotopic Constraints on the Provenance of Antarctic Dust and Atmospheric Circulation Patterns Prior to the Mid-Brunhes Event (~430 kyr ago)

Molecules, 2022
A lead (Pb) isotopic record, covering the two oldest glacial–interglacial cycles (~572 to 801 kyr ago) characterized by lukewarm interglacials in the European Project for Ice Coring in Antarctica Dome C ice core, provides evidence for dust provenance in ...

The signature of river- and wind-borne materials exported from Patagonia to the southern latitudes: a view from REEs and implications for paleoclimatic interpretations [PDF]

, 2004
Riverine and wind-borne materials transferred from Patagonia to the SW Atlantic exhibit a homogeneous rare earth element (REE) signature. They match well with the REE composition of Recent tephra from the Hudson volcano,and hence this implies a ...

Velocities of Major Outlet Glaciers of the Patagonia Icefield Observed by TerraSAR-X [PDF]

, 2008
The capabilities of TerraSAR-X data for feature tracking by amplitude correlation over glacier surfaces are investigated. Methodical aspects of the amplitude correlation approach are described.

A uniform isotopic and chemical signature of dust exported from Patagonia: Rock sources and occurrence in southern environments [PDF]

, 2007
Patagonia is considered to be the most important source of dust from South America that is deposited in surrounding areas, and we present here a systematic Sr and Nd isotopic study of sediment currently being exported.

Cryptic speciation in a benthic isopod from Patagonian and Falkland Island waters and the impact of glaciations on its population structure

Frontiers in Zoology, 2008
Background The Falkland Islands and Patagonia are traditionally assigned to the Magellan Biogeographic Province. Most marine species in Falkland waters are also reported from southern Patagonia.

Recent increase in autumn temperature has stabilized tree growth in forests near the tree lines in Chilean Patagonia

Ecosphere, 2022
It is widely accepted that global warming is affecting forests near the tree line by increasing tree growth in these cold‐limited environments. However, since about 1970, a reduction in tree growth near the tree line has been observed in response to ...

Estimación sexual en restos óseos de cazadores-recolectores de Patagonia central argentina: contrastación de métodos morfométricos con análisis paleogenéticos

Revista Argentina de Antropología Biológica, 2021
En el presente trabajo se comparan los resultados de la estimación de sexo en restos óseos humanos antiguos de individuos adultos de la Patagonia central argentina (N=42) a partir de dos métodos: por una parte, el estudio de estructuras de la pelvis, el ...

Distribution and abundance of Chubut Steamerducks: an endemic species to Central Patagonia, Argentina [PDF]

Bird Conservation International, 2011
SummaryWe documented the breeding distribution and estimated abundance of Chubut SteamerducksTachyres leucocephalus,a flightless waterbird endemic to a relatively small section of coastline in Patagonia, Argentina. The distribution of Chubut Steamerducks is restricted to approximately 700 km of coast.
