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 ...
Chemical and functional characterization of antimicrobial metabolites isolated from ascidian Rhopalaea Birkelandi
(Universidad Nacional (Costa Rica), 2011-12)
Marine ecosystems have a very large diversity of resources, most of them still partially unknown, and a
few others exploited for development of new industrial and toxicological products. The objective of this
investigation ...
Groundwater recharge mechanisms inferred from isoscapes in a complex tropical mountainous region
(AGU Publications, 2016-05-23)
Stable isotope variations and groundwater recharge mechanisms remain poorly understood across the tropics, particularly in Central America. Here stable isotopes (δ18O and δ2H) in groundwater, surface water, and rainfall ...
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 ...
Análisis de las Olimpiadas Nacionales de Química en Costa Rica: Alcances y retos para la población joven
(Universidad Nacional (Costa Rica), 2012)
La Escuela de Química ha promovido programas y proyectos académicos como las Olimpiadas de Química que estimulen y mejoren el aprendiza-je de esta ciencia. Como competencia se identifican estudiantes de alto desempeño ...
Environmental impact assessment of 17 construction projects in various university campuses
(WIT Press, 2018)
Environmental impact assessment (EIA) is the process of evaluating the environmental consequences
of a plan, policy, programme or any other project prior to the execution of the proposed action; it is
the primary ...
National Inventory of Mercury Release into Different Environmental Sectors Estimated by United Nations Environment Programme (UNEP) Toolkit in Costa Rica
(United Nations Environment Programme (UNEP) Toolkit, 2017)
This paper summarizes the national inventory of mercury released into all environmental sectors (air, water, land, impurity in products, general wastes and sector specific treatment/disposal) for the year 2008 in the country ...
Evaluación de la concentración de los aldehídos en el aire en la Reserva Biológica Monteverde y en la ciudad de Heredia, Costa Rica
(Universidad Nacional (Costa Rica), 2016)
Se determinó la concentración de seis aldehídos en muestras de aire, durante abril-junio de 2015, en la Reserva Bioló gica Monteverde (RBM) y en Heredia, Costa Rica. El formaldehído, el acetaldehído, el propanal, el butanal, ...
Perfil nacional de uso de mercurio en Costa Rica a la luz de la entrada en vigencia del Convenio de Minamata
(Universidad Nacional (Costa Rica), 2017)
El mercurio es un metal cuya inadecuada gestión puede poner en riesgo la salud y el medio ambiente,
y debido a que en el país no existe una herramienta que le permita establecer los controles para su gestión, se elaboró ...
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 ...
