Evolution of ice-dammed proglacial lakes in Última Esperanza, Chile: implications from the late-glacial R1 eruption of Reclús volcano, Andean Austral Volcanic Zone
(Servicio Nacional de Geología y Minería (SERNAGEOMIN), 2011)
Late Pleistocene glaciolacustrine MIS 3 record at Fagnano Lake, central Tierra del Fuego, southern Argentina
(Cambridge University Press, 2020-12-14)
A late Pleistocene glaciolacustrine record was studied at Fagnano Lake (54°35´S, 67°20´W), central Isla Grande de Tierra del Fuego, southernmost South America. Two profiles from the Río Valdéz outcrop were collected for ...
Trace elements determined in sediment cores from Nhecol??ndia Pantanal by INAA
(Instituto de Pesquisas Energ??ticas e Nucleares, 2018)
Paleoenvironmental interpretation of the Holocene of Corrientes province, Argentina
(Wiley Blackwell Publishing, Inc, 2019-07)
The objective of the present paper is to recognize and reconstruct, from the analysis of pollen recovered from sedimentary cores, the predominant plant communities and their variations during the Holocene in Corrientes ...
Fossil pigments and environmental conditions in the oligotrophic Laja Lake in the Chilean Andes
(2022-03)
Interactions among climate change, ozone depletion, and ultraviolet radiation affect aquatic ecosystems. Meteorological and biological monitoring is often too brief, however, to record the magnitudes of past changes in ...
Trace metal partitioning and potential mobility in the naturally acidic sediment of Lake Caviahue, Neuquén, ArgentinaFraccionamiento y mobilidad potencial de metales traza en el sedimento ácido natural del lago Caviahue, Neuquén, Argentina
(Servicio Nacional de Geología y Minería, 2020-01)
El Lago Caviahue es un cuerpo de agua extremadamente ácido ubicado en el norte de la Patagonia Argentina. La acidez se debe a que la naciente de uno de sus afluentes principales se encuentra en un manantial de efluentes ...
Records of environmental changes during the Holocene from Isla de los Estados (54.4°S), southeastern Tierra del Fuego
(Elsevier Science, 2010-12)
Southernmost Patagonia, located at the relatively narrow passage between Antarctica and South America, is a highly sensitive region for recording meridional and zonal changes in the pattern of oceanic and atmospheric ...
Pollen-and diatom based environmental history since the Last Glacial Maximum from the Andean core Fúquene-7, Colombia
(JOHN WILEY & SONS LTD, 2003-01-01)
The late Pleistocene-Holocene ecological and limnological history of Lake Fúquene (2580 m a.s.l.), in the Colombian Andes, is reconstructed on the basis of diatom, pollen and sediment analyses of the upper 7 m of the core ...
A one-century sedimentary record of N- and S-polycyclic aromatic compounds in the Athabasca oil sands region in Canada
(Elsevier, 2020)
The atmospheric deposition of polycyclic aromatic compounds (PACs) is considered a major pathway to isolated lakes and bogs in the Athabasca oil sands region (AOSR), Canada. However, the suite of PACs measured has been ...
Isotopic fingerprints on lacustrine organic matter from Laguna Potrok Aike (southern Patagonia, Argentina) reflect environmental changes during the last 16,000 years
(Springer, 2009-06)
A combination of carbon-to-nitrogen ratios (TOC/TN), Rock Eval-analyses, and stable isotope values of bulk nitrogen (δ15N) and organic carbon (δ13Corg) was used to characterize bulk organic matter (OM) of a piston core ...
