Isotope hydrology and baseflow geochemistry in natural and human-altered watersheds in the Inland Pacific Northwest, USA
(2015-02-18)
This study presents a stable isotope hydrology and geochemical analysis in the inland Pacific Northwest (PNW) of the USA. Isotope ratios were used to estimate mean transit times (MTTs) in natural and human-altered watersheds ...
Spatial and Temporal Variation of Stable Isotopes in Precipitation across Costa Rica: An Analysis of Historic GNIP Records
(2013-11-27)
The location of Costa Rica on the Central American Isthmus creates unique microclimate systems that receive moisture inputs directly from the Caribbean Sea and the Pacific Ocean. In Costa Rica, stable isotope monitoring ...
Moisture transport and seasonal variations in the stable isotopic composition of rainfall in Central American and Andean Páramo during El Niño conditions (2015–2016)
(John Wiley and Sons Ltd, 2019)
High‐elevation tropical grassland systems, called Páramo, provide essential ecosystem services such as water storage and supply for surrounding and lowland areas.
Páramo systems are threatened by climate and land use ...
Isotope hydrology of a tropical coffee agroforestry watershed: Seasonal and event-based analyses
(Wiley & Sons, 2018)
Stable isotope variations are extremely useful for flow partitioning within the
hydrologic cycle but remain poorly understood throughout the tropics, particularly in
watersheds with rapidly infiltrating soils, such as ...
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 ...
GPS PrecipitableWater Vapor Estimations over Costa Rica: A Comparison against Atmospheric Sounding and Moderate Resolution Imaging Spectrometer (MODIS)
(MDPI, 2019)
The quantification of water vapor in tropical regions like Central America is necessary to estimate the influence of climate change on its distribution and the formation of precipitation. This work reports daily estimations ...
Tracking the water fingerprints of Cocos Island: A stable isotope analysis of precipitation, surface water, and groundwater
(Revista de Biología Tropical, 2016)
The use of stable isotopes of water, both δ2H and δ18O has provided novel insights in hydrological studies, ecological applications, understanding climate variability, and reconstructing paleoclimate. However, information ...
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 ...
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 ...
Análisis de vapor de agua precipitable sobre Costa Rica: una comparación entre diferentes técnicas de análisis basadas en GPS, sondeo atmosférico y productos satelitales MODIS
(Universidad Nacional (Costa Rica), 2019)
La cuantificación del vapor de agua en regiones tropicales como América Central es necesaria para estimar la influencia del cambio climático en su distribución y la formación de precipitaciones. Este trabajo analiza las ...
