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 ...
Climate And Water Conflicts Coevolution From Tropical Development And Hydro-Climatic Perspectives: A Case Study Of Costa Rica
(American water resources Association, 2018)
Costa Rica is a nation with a vast wealth of water resources; however, recently the country has
faced water conflicts (WC) due to social, economic, legal, and political impediments in response to limited water
availability ...
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 ...
Dry season plant water sourcing in contrasting tropical ecosystems of Costa Rica
(John Wiley & Sons (Estados Unidos), 2023)
Tracer-aided studies to understand plant water uptake sources and dynamics in tropical
ecosystems are limited. Here, we report the analysis of dry season source water
uptake patterns of five unique ecosystems of Costa ...
Isotopic composition and major ion concentrations of national and international bottled waters in Costa Rica
(Elsevier (Países Bajos), 2021)
Global bottled water consumption has largely increased (14.35 billion gallons in 2020) [1], [2], [3], [4], [5] during the last decade since consumers are demanding healthier and safer forms of rehydration. Bottled water ...
Hydroclimatic and ecohydrological resistance/resilience conditions across tropical biomes of Costa Rica
(John Wiley & Sons (Estados Unidos), 2017)
Water resources management in the tropics is challenged by climate variability and unregulated
land use change and their impacts on the complex interactions between vegetation, soil, and
atmosphere. This study focuses ...
Variación Espacial de la Composición de 222RN en los Acuíferos Barva y Colima Superior, Costa Rica
(Universidad de Costa Rica (Costa Rica), 2016)
Radon (222Rn) is a useful natural-occurring tracer to elucidate groundwater to surface water connectivity
with important implications for human health. This study presents the first spatial distribution of 222Rn in ...
Near Surface Carbon Dioxide and Methane in Urban Areas of Costa Rica
(Scientific Research Publishing (China), 2015)
Little information is available for Central America regarding methane and carbon dioxide mixing
ratios in urban areas. This work reports a representative spatial and seasonal study of near surface
carbon dioxide and ...
