A biological and nitrate isotopic assessment framework to understand eutrophication in aquatic ecosystems
(Elsevier, 2020-05)
Eutrophication is a globally significant challenge facing aquatic ecosystems, mostly associated with human induced enrichment of these ecosystems with nitrogen and phosphorus. Given the complexity of assigning eutrophication ...
Reconstruction of the hydrologic history of a shallow Patagonian steppe lake during the past 700 yr, using chemical, geologic, and biological proxies
(Cambridge University Press, 2017-03-24)
The limnological conditions during the past 700 yr were reconstructed based on multiproxy analysis of a short sedimentary sequence from El Toro Lake (~40°S, 70°W). Mineralogical and geochemical features, as well as ostracods ...
Climate-driven changes in sedimentation rate influence phosphorus burial along continental margins of the northwestern Mediterranean
(Elsevier, 2018)
The burial of phosphorus (P) in continental margin sediments is a critical component of the marine reactive P budget, and thus an important factor in marine biological productivity. We determined downcore records of P from ...
The Argentine Continental Margin: A Potential Paleoclimatic-Paleoceanographic Archive for the Southern Ocean
(Springer Verlag Berlín, 2017)
The Argentina Continental Margin, located in the Southwestern Atlantic Ocean, is inserted in a key region of the World Ocean due to its significance in the global oceanographic-climatic interaction, and because it is the ...
Late Holocene hydrology inferred from lacustrine sediments of Laguna Cháltel (southeastern Argentina)
(Elsevier Science, 2014-07)
Hydrological changes that occurred during the last 4700 years have been reconstructed using multi-proxy analyses of sediment cores from the volcanic crater lake of Laguna Cháltel (50°S, 71°W). The chronology is based on ...
Micromorfología de paleosuelos del Desierto de la Tatacoa, Colombia: Interpretación paleoambiental del Mioceno Medio
(Bogotá - Ciencias - Maestría en Ciencias - GeologíaDepartamento de GeocienciasUniversidad Nacional de Colombia - Sede Bogotá, 2020-12-04)
Mediante análisis micromorfológicos se identificaron características pedogenéticas asociadas con la estacionalidad en el régimen de humedad en paleosuelos del miembro Baraya, en el Desierto de la Tatacoa, Colombia. ...
Population response during an Oceanic Anoxic Event: The case of Posidonotis (Bivalvia) from the Lower Jurassic of the Neuquén Basin, Argentina
(Elsevier Science, 2019-07-01)
Benthonic marine species show a wide range of biological reactions to seawater chemical changes through time, from subtle adjustments to extinction. The Early Toarcian Oceanic Anoxic Event (T-OAE) was recently recognized ...
