Biological Cr(VI) removal coupled with biomass growth, biomass decay, and multiple substrate limitation
(Pergamon-Elsevier Science Ltd, 2011-05)
In this work, a mathematical model for the biological reduction of Cr(VI), carbon and nitrogen sources consumption, and biomass growth under fully aerobic conditions was developed. The model comprises three types of aerobic ...
Water geochemistry of shallow lakes from the southeastern Pampa plain, Argentina and their implications on mollusk shells preservation
(Elsevier Science, 2017-12-15)
A seasonal sampling of sediments, column and interstitial water for physico-chemical analysis were performed in littoral and open water areas in three freshwater shallow lakes (Nahuel Rucá, Las Mostazas and Los Carpinchos) ...
Carbonate laminae recorded in a siliciclastic tidal flat colonized by microbial mats
(Elsevier Science, 2020-07-15)
Microbial mats in siliciclastic coastal environments are considered as non-lithifying systems that lack the potential for calcification. This work documents precipitation and preservation of well-defined, laterally continuous ...
High quality residues from cover crops favor changes in microbial community and enhance C and N sequestration
(2016)
The objective of the study was to evaluate the effect of a change in management on the soil microbial community and C sequestration. We conducted a 3-year field study in La Pampa (Argentina) with rotation of sorghum (Sorghum ...
Dissolved major and trace geochemical dynamics in Antarctic lacustrine systems
(Pergamon-Elsevier Science Ltd, 2020-02)
Clearwater Mesa (James Ross Island, northeast Antarctic Peninsula) provides a unique opportunity to study solute dynamics and geochemical weathering in the pristine lacustrine systems of a high latitude environment. In ...
Response of Coastal Phytoplankton to High Inflows of Terrestrial Matter
(Frontiers Media S.A., 2020-02)
Climate change scenarios project that precipitation will increase in northern Europe, causing amplified inflows of terrestrial matter (tM) and inorganic nutrients to coastal areas. How this will affect the plankton community ...
Solar UV radiation in a changing world: roles of cryosphere-land-water-atmosphere interfaces in global biogeochemical cycles
(Royal Society of Chemistry, 2019-01)
Global change influences biogeochemical cycles within and between environmental compartments (i.e., the cryosphere, terrestrial and aquatic ecosystems, and the atmosphere). A major effect of global change on carbon cycling ...
Geochemistry of aggradational - Progradational sequence sets of the Upper Jurassic – Lower Cretaceous Vaca Muerta shales (Añelo area, Neuquén Basin, Argentina): Relation to changes in accommodation and marine anoxia
(Pergamon-Elsevier Science Ltd, 2019-08)
Unconventional shale plays have received marked attention over the last years because of their economic potential for hydrocarbon generation. The size and geology of the Neuquén Basin of western Argentina lends to large ...
Role of a non-ionic surfactant and carboxylic acids on the leaching of aged DDT residues in undisturbed soil columns
(Springer Heidelberg, 2019-04)
Purpose: Irrigation or flooding events with riverine waters containing compounds such as surfactants, colloids, and dissolved organic carbon and plant growth will modify pesticide availability and leaching. This work studies ...
Pedogenic and subaerial exposure microfabrics in a late carboniferous-early permian carbonate-volcanic lacustrine-palustrine system (SAn Ignacio Formation, Frontal Cordillera, Argentina)Microfábricas pedogénicas y de exposición subaérea en el sistema volcánico y lacustre de la formación san ignacio (Carbonífero Superior-Pérmico Inferior), Cordillera Frontal, Argentina
(Servicio Nacional de Geología y Minería, 2020-05)
In the Argentinian Andes (Frontal Cordillera) the upper part of the late Carboniferous-early Permian San Ignacio Formation is made up of lacustrine-palustrine microbial carbonates and interbedded volcanic deposits. In this ...
