The observed North Atlantic Meridional Overturning Circulation, its Meridional Coherence and Ocean Bottom Pressure [PDF]

open access: yes, 2014
Analyses of meridional transport time series from the Rapid Climate Change–Meridional Overturning Circulation (RAPID MOC) array at 26°N and from Argo float and altimetry data at 41°N reveal that, at semiannual and longer time scales, the contribution ...

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

open access: yes, 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]

open access: yes, 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.

Propuesta metodológica para el estudio de la variabilidad en el uso de fuentes líticas (campo volcánico Pali Aike, Patagonia argentina)

open access: yesRevista del Museo de Antropologia, 2023
La roca de grano fino oscura tipo Potrok Aike (RGFO PKA) fue la más utilizada por los cazadores-recolectores para confeccionar artefactos en el campo volcánico Pali Aike (CVPA), Patagonia meridional. A pesar de la importancia regional del recurso lítico,

Análisis multi-criterio sobre barreras biogeográficas para la movilidad humana en Patagonia meridional

open access: yesEstudios Atacameños, 2020
Buena parte de la discusión sobre la biogeografía humana del sistema lacustre al sur de Lago Argentino (Patagonia meridional) ha estado centrada en los “callejones sin salida”, próximos a los lagos andinos, su vinculación con el hielo continental como ...

Atlantic Meridional Overturning Circulation slowdown cooled the subtropical ocean [PDF]

open access: yes, 2013
Observations show that the upper 2 km of the subtropical North Atlantic Ocean cooled throughout 2010 and remained cold until at least December 2011. We show that these cold anomalies are partly driven by anomalous air-sea exchange during the cold winters

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]

open access: yes, 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 ...

Ploidy levels and reproductive behaviour in invasive Hieracium pilosella in Patagonia [PDF]

open access: yes, 2011
Within a population of invasive Hieracium pilosella in Chilean Patagonia we found two ploidy levels, pentaploid and hexaploid. Each ploidy level was represented by one clone.
