Identifying groundwater recharge connections in the Moscow (USA) sub-basin using isotopic tracers and a soil moisture routing model
(Springer, 2016)
Globally, aquifers are suffering from large abstrac tions resulting in groundwater level declines. These declines can be caused by excessive abstraction for drinking water, irrigation purposes or industrial use. Basaltic ...
Isotopic composition in precipitation and groundwater in the northern mountainous region of the Central Valley of Costa Rica
(Taylor & Francis, 2016)
The linkage between precipitation and recharge is still poorlyunderstood in the Central America region. This study focuses onstable isotopic composition in precipitation and groundwater in the northern mountainous region ...
Deciphering key processes controlling rainfall isotopic variability during extreme tropical cyclones
(2019-09)
The Mesoamerican and Caribbean (MAC) region is characterized by tropical cyclones (TCs), strong El Niño-Southern Oscillation events, and climate variability that bring unique hazards to socio-ecological systems. Here we ...
Hydrogeological responses in tropical mountainous springs
(Taylor and Francis Ltd., 2018)
This study presents a hydrogeochemical analysis of spring
responses (2013–2017) in the tropical mountainous region of the
Central Valley of Costa Rica. The isotopic distribution of δ18O and
δ2
H in rainfall resulted ...
Key drivers controlling stable isotope variations in daily precipitation of Costa Rica: Caribbean Sea versus Eastern Pacific Ocean moisture sources
(Elsevier, 2016)
Costa Rica is located on the Central American Isthmus, which receives moisture inputs directly from the Caribbean Sea and the Eastern Pacific Ocean. This location includes unique mountainous and lowland microclimates, but ...
ENSO sentinels in the Americas' humid tropics: We need combined hydrometric and isotopic monitoring for improved El Niño and La Niña impact prediction
(John Wiley & Sons (Estados Unidos), 2023)
This Scientific Briefing presents results from a nearly 10-year hydrometric and isotope
monitoring network across north-central Costa Rica, a region known as a
headwater-dependent system. This monitoring system has ...
Nitrate Legacy in a Tropical and Complex Fractured Volcanic Aquifer System
(John Wiley & Sons (Estados Unidos), 2023)
Nitrate legacy is affecting groundwater sources across the tropics. This study describes isotopic
and ionic spatial trends across a tropical, fractured, volcanic multi-aquifer system in central Costa Rica in
relation to ...
Exploring the acid neutralizing effect in rainwater collected at a tropical urban area: Central Valley, Costa Rica
(Elsevier (Países Bajos), 2023)
We report on the chemical and the carbon isotopic composition of dissolved inorganic carbon (DIC) of rainwater
collected between May and October 2020 in the Central Valley, Costa Rica. Precipitation samples were ...
Hydrometeorological Factors Controlling the Stable Isotopic Composition of Precipitation in the Highlands of South Ecuador
(American Meteorological Society (Estados Unidos), 2022-07)
Knowledge about precipitation generation remains limited in the tropical Andes due to the lack of water stable isotope (WSI) data. Therefore, we investigated the key factors controlling the isotopic composition of precipitation ...
Water stable isotopes reveal the hydrological response of Costa Rican glacial lakes to climate variability
(Elsevier (Países Bajos), 2022)
Los lagos generalmente se consideran una fuente de información clave para comprender el paleoclima. Aquí usamos estable.
Isótopos de agua (δ2H y δ18O) en un lago glacial tropical de gran altitud para informar sobre la ...
