Isotope Tracing of the Parana River, Argentina
(International Atomic Energy Agency, 2012-05)
The Rio de la Plata estuary is the collector of a vast drainage basin of about 3.1x106 km2 . There are many tributaries to the estuary but the Parana and Uruguay rivers directly discharge more than 99% of the average ...
Controls over spatial and seasonal variations on isotopic composition of the precipitation along the central and eastern portion of Brazil
(2017-09-03)
Based on Global Network Isotopes in Precipitation (GNIP) isotopic data set, a review of the spatial and temporal variability of δ18O and δ2H in precipitation was conducted throughout central and eastern Brazil, indicating ...
Stable isotopes reveal groundwater to river connectivity in a mesoscale subtropical watershed
(2021-01-01)
The Corumbataí River basin (São Paulo, Brazil) has a critical situation regarding water availability due to the intensive use to support agriculture and urbanization, requiring scientific information to face water demand. ...
The forest effects on the isotopic composition of rainfall in the northwestern Amazon Basin
(American Geophysical Union (AGU), 2020-02-27)
In the Amazon basin, intense precipitation recycling across the forest significantly modifies the isotopic composition of rainfall (δ¹⁸O, δD). In the tropical hydrologic cycle, such an effect can be identified through ...
Stable water isotopes of precipitation and firn cores from the northern Antarctic Peninsula region as a proxy for climate reconstruction
(COPERNICUS GESELLSCHAFT MBHGOTTINGEN, 2012)
In order to investigate the climate variability in the northern Antarctic Peninsula region, this paper focuses on the relationship between stable isotope content of precipitation and firn, and main meteorological variables ...
Stable isotopes reveal groundwater to river connectivity in a mesoscale subtropical watershed
(Taylor and Francis Ltd., 2021)
The Corumbataí River basin (São Paulo, Brazil) has a critical situation regarding water availability due to the intensive use to support agriculture and urbanization, requiring scientific information to face water demand. ...
Groundwater and surface water connectivity within the recharge area of Guarani aquifer system during El Niño 2014–2016
(2018-07-30)
Recharge areas of the Guarani Aquifer System (GAS) are particularly sensitive and vulnerable to climate variability; therefore, the understanding of infiltration mechanisms for aquifer recharge and surface run-off generation ...
Níveis de carboidratos e lipídios em dietas para juvenis de tambaqui (Colossoma macropomum): variáveis produtivas, fisiológicas e turnover isotópico
(Universidade Estadual Paulista (UNESP), 2016)
Impact of elevation and weather patterns on the isotopic composition of precipitation in a tropical montane rainforest
(2013)
This study presents the spatial and temporal variability of δ18O and δ2H isotope signatures in precipitation of a south Ecuadorian montane cloud forest catchment (San Francisco catchment). From 2 September to 25 December ...
Significado del exceso de deuterio en la interpretación de isótopos estables δ 18-O y δ 2-H en estudios hidrogeológicos
(LimaPE, 2014-11)
Se incorpora un elemento de análisis que ayuda con información en la interpretación de los isótopos estables δ 18-O y deuterio en los estudios hidrogeológicos, denominado exceso de deuterio “δ” que en el presente estudio ...
