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 ...
Orientation effect in poly (butylene succinate) fibers
(Polymers & Polymer Composites vol.11 no.1 51-56 2003, 2003)
Fibers of poly (butylene succinate) (PBS) were prepared using a single screw extruder at various take-up speeds. Changes in fiber structure, morphology and physical properties were investigated using sonic velocity ...
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. ...
Evaluación de los niveles de hidrocarburos en sedimentos marinos, su posible origen y efectos sobre la actividad de acuicultura entre Punta Morales y Costa de Pájaros en el Golfo de Nicoya
(Universidad Nacional (Costa Rica), 2014)
En el presente trabajo se realizó una evaluación de los niveles de hidrocarburos en los
sedimentos marinos de la región interna del Golfo de Nicoya, como insumo para determinar
su posible efecto sobre las actividades de ...
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 ...
Análisis hidroclimático en condiciones no estacionarias utilizando el marco teórico de Budyko: el caso del páramo de Costa Rica
(Universidad Nacional (Costa Rica), 2019)
La gestión del recurso hídrico en los trópicos se ha visto recientemente desafiada por la variabilidad del clima y los cambios no controlados en el uso de la tierra y sus impactos en las complejas interacciones entre la ...
