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 ...
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 ...
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 ...
Exploring Dissolved Organic Carbon Variations in a High Elevation Tropical Peatland Ecosystem: Cerro de la Muerte, Costa Rica
(Frontiers Media (Suiza), 2022-01)
Tropical peatlands are distributed mainly in coastal lowlands; however high elevation regions exhibit a large prevalence of small and fragmented peatlands that are mostly understudied. Artificial drainage of peatlands to ...
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 ...
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 ...
Data Descriptor: Daily observations of stable isotope ratios of rainfall in the tropics
(Springer Nature (Alemania), 2019)
We present precipitation isotope data (δ2H and δ18O values) from 19 stations across the tropics collected
from 2012 to 2017 under the Coordinated Research Project F31004 sponsored by the International
Atomic Energy Agency. ...
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 ...
