Variations in sediment yield over the advance and retreat of a calving glacier, Laguna San Rafael, North Patagonian Icefield
(Elsevier, 2010)
Bathymetric and sub-bottom acoustic data were collected in Laguna San Rafael, Chile, to determine sediment
yields during the Little Ice Age advance and subsequent retreat of San Rafael Glacier. The sediment volumes
and ...

Seasonal benthic patterns in a glacial Patagonian fjord: the role of suspended sediment and terrestrial organic matter
(2016)
Complex marine-terrestrial interactions characterize Chilean fjords, where benthic communities influence the distribution of organic matter (OM). We examined spatial and seasonal changes in the hydrography, sediment ...
In and out of glacial extremes by way of dust-climate feedbacks
(2018)
Mineral dust aerosols cool Earth directly by scattering incoming solar radiation and indirectly by affecting clouds and biogeochemical cycles. Recent Earth history has featured quasi-100,000-y, glacial-interglacial climate ...

Effect of glacial lake outburst floods on the light climate in an Andean Patagonian lake: implications for planktonic phototrophs
(Springer, 2018-07)
Climate change is altering temperature and precipitation patterns all over the world. In North Patagonia, glaciers of the Tronador mountain (41°S) show a continuous and maintained recession, and these meltwaters are ...
Glacier and terrestrial ecosystem evolution in the Chilotan archipelago sector of northwestern Patagonia since the Last Glacial Termination
(2022)
We examine the glacier, terrestrial ecosystem, and climate evolution since the Last Glacial Termination (T1) based on glacial sediments/landform assemblages and palynological data from the Chilotan archipelago (41°30′S-43°30′S), ...
Tunnel-valley fills in the Paraná Basin and their implications for the extent of late Paleozoic glaciation in SW Gondwana
(2021-03-01)
Tunnel valleys are subglacial incisions formed mainly by meltwater erosion on soft sediment overridden by glaciers. Despite being common in the Pleistocene and Ordovician glacial record, where their fills constitute excellent ...
ICE-KEEL SCOUR MARKS IN THE GEOLOGICAL RECORD: EVIDENCE FROM CARBONIFEROUS SOFT-SEDIMENT STRIATED SURFACES IN THE PARANA BASIN, SOUTHERN BRAZIL
(Sepm-soc Sedimentary Geology, 2014-01-01)
Soft-sediment glacially striated surfaces are common structures in ancient glacial successions, such as the Gondwanic Paleozoic record, and document ice erosion on non lithified beds. In most cases, they have been interpreted ...
Evolution of ice-dammed proglacial lakes in Última Esperanza, Chile: Implications from the late-glacial R1 eruption of Reclús volcano, Andean Austral Volcanic Zone Evolución de lagos proglaciales embalsados por hielo en Última Esperanza, Chile: Implicanci
(2011)
Newly described outcrops, excavations and sediment cores from the region of Última Esperanza, Magallanes, contain tephra derived from the large late-glacial explosive R1 eruption of the Reclús volcano in the Andean Austral ...
