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 ...

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.

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 ...
