Abrupt drainage of Lago Greve, a large proglacial lake in Chilean ...
2022年8月26日 · Here we report an outburst of Lago Greve, a large proglacial lake in Chilean Patagonia. During the event in April–July 2020, the lake level dropped by 18.3 ± 1.2 m and the area decreased by...
Glacial Erosion Rates Since the Last Glacial Maximum for the …
2024年12月15日 · In this study, we present glacial erosion rates calculated from data imaging glacial sediments preserved in a lake in Patagonia, Argentina. To understand the effect of the time interval length, we calculate glacial erosion rates for …
Glacial lake drainage in Patagonia (13-8 kyr) and response of the ...
2016年2月12日 · We use 16 new single-grain optically stimulated luminescence (OSL) dates to define three stages of rapid glacial lake drainage in the Lago General Carrera/Lago Buenos Aires and Lago...
Transient glacial incision in the Patagonian Andes from ~6 Ma …
2020年2月12日 · We report a mountain-scale record of erosion rates in the central Patagonian Andes from >10 million years (Ma) ago to present, which covers the transition from a fluvial to alpine glaciated landscape.
We use 16 new single-grain optically stimulated luminescence (OSL) dates to define three stages of rapid glacial lake drainage in the Lago General Carrera/Lago Buenos Aires and Lago Cohrane/...
Catastrophic glacial-lake outburst flooding of the Patagonian …
2020年1月1日 · Here, we provide the first detailed reconstruction of catastrophic glacial lake outburst flooding from the Southern Hemisphere, focusing on the Río Baker catchment in central Patagonia. Firstly, we review the evidence for palaeolake drainage events in the Baker catchment showing the basin witnessed a number of events during Late Quaternary ...
The 2015 Chileno Valley glacial lake outburst flood, Patagonia
2019年5月1日 · In December 2015 a large GLOF event occurred at Lago Chileno in southern Patagonia causing extensive damage to a vegetated alluvial plain located immediately downstream of the breach before entering an ice-dammed lake located on the eastern flank of Exploradores Glacier and then draining into the Río Exploradores.
Here, we investigate the Middle and Late Pleistocene sedimentary record of the continental slope from Ocean Drilling Program (ODP) Site 861, offshore Patagonia (46°S), to evaluate the link between glaciations, mountain range erosion and continental margin strata formation.
A glacial lake outburst floods hazard assessment in the …
2024年3月15日 · We present a glacial-related lake inventory for a region spanning 41.5° - 47° S in Patagonian Andes, where information on past glacier lake outburst floods (GLOF's) has hitherto remained significantly underreported. Analyzing remotely sensed images, we obtained data on 702 glacial-related lakes.
Hydrologic and geomorphic changes resulting from episodic glacial lake ...
2016年12月21日 · The primary response in the LC2 lake basin due to repeated filling and draining associated with episodic GLOFs was the rapid erosion of sediments stored within the lake basin (Figures 2 and S5–S9). In less than a year after GLOFs initiated, sediment removal expanded the length of LC2 by ~2 km (Figure S9 ).
