The glacial geomorphology of the Cordillera Darwin Icefield, Tierra del Fuego, southernmost South America
The Cordillera Darwin Icefield (CDI) has experienced widespread retreat since the Little Ice Age (LIA, ∼1870 AD). Prior to this, information on outlet glacier dynamics is limited as there are few terrestrial observations and little mapped deglacial evidence, limiting our understanding of CDI dynamics on Holocene centennial to millennial timescales. Here we present a glacial geomorphological map of terrestrial landforms and features for the CDI an…
Máxima expansión del Glaciar Tenerife (51°S) durante el último milenio
En los Andes Patagónicos aún es materia de debate cuándo los glaciares alcanzaron su máxima expansión durante el último milenio. En este trabajo analizamos las fluctuaciones del Glaciar Tenerife (51°S), un pequeño glaciar de montaña ubicado inmediatamente al sur de los Campos de Hielos Patagónicos. Un análisis detallado de las geoformas glaciales del valle nos permitió identificar tres sistemas de morrenas, en la parte sur-central, suroccidental …
Holocene glacier history of northeastern Cordillera Darwin, southernmost South America (55°S)
In the Cordillera Darwin, southernmost South America, we used 10 Be and 14 C dating, dendrochronology, and historical observations to reconstruct the glacial history of the Dalla Vedova valley from deglacial time to the present. After deglacial recession into northeastern Darwin and Dalla Vedova, by ~16 ka, evidence indicates a glacial advance at ~13 ka coeval with the Antarctic Cold Reversal. The next robustly dated glacial expansion occurred at…
Glacial geomorphology of the Marinelli and Pigafetta glaciers, Cordillera Darwin Icefield, southernmost Chile
This paper presents a glacial geomorphological map relating to two rapidly receding glaciers in the Cordillera Darwin Icefield. The Marinelli marine-terminating glacier and Pigafetta freshwater-terminating glacier are selected to represent different glacial regimes producing different geomorphological records under similar climatic conditions. We combine mapping from satellite and aerial imagery with fieldwork, updating limited previous mapping. …
Parque nacional bernardo o’higgins/territorio kawésqar waes
La gestión de áreas protegidas y la conservación de sus recursos naturales es una materia en permanente desarrollo y sobre la cual se han planteado diversos enfoques. Actualmente excluir a las comunidades humanas con derechos ancestrales de los parques nacionales es políticamente inviable y percibido como éticamente injustificable, sobre todo en países en desarrollo donde es cada vez más importante el reconocimiento de los derechos de sus habitan…
A 970-year-long summer temperature reconstruction from Rogen, west-central Sweden, based on blue intensity from tree rings
To assess past climate variability in west-central Scandinavia, a new 972-year-long temperature reconstruction, based on adjusted delta blue intensity (ΔBI adj ), was created. Presently, it is the longest blue intensity chronology in Fennoscandia and the third longest in the northern hemisphere. Measurements were obtained from 119 tree line Scots pine ( Pinus sylvestris L.) samples from Rogen, in the central Scandinavian Mountains, Sweden. Early …
Equilibrium line altitudes along the Andes during the Last millennium
Deciphering the climate changes that influenced the glacial fluctuations of the last millennium requires documenting the spatial and temporal patterns of these glacial events. Here, we estimate the change in equilibrium line altitudes (ELAs) between the most prominent glacial advance of the last millennium and the present for four alpine glaciers located in different climatic regimes along the Andes. For each glacier, we reconstruct scenarios of …
