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 ...
Preliminary inventory of atmospheric emissions (SO2, NOx and TSP) from different industrial sectors in Costa Rica
(Universidad Nacional (Costa Rica), 2021-07-31)
El uso de diversos combustibles, el incremento de la urbanización, y el desarrollo económico, han influido en la generación de contaminantes atmosféricos, tales como los NOx (óxidos de nitrógeno), el SO2 (dióxido de azufre) ...
Acercamiento a los procesos de modelación de la calidad del agua en una subcuenca. Caso del río Virilla, Costa Rica
(Universidad Nacional, Costa Rica, 2021-01-31)
Se realizó la implementación de un modelo de calidad del agua superficial, a través del cual se procuraba hacer un primer acercamiento a los procesos de modelado matemático como insumo para la gestión integrada ...
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 ...
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 ...
Key drivers controlling stable isotope variations in daily precipitation of Costa Rica: Caribbean Sea versus Eastern Pacific Ocean moisture
(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 ...
Tracer-aided modelling reveals quick runo generation and groundwater losses producing young stream ow ages in a tropical rainforest catchment
(2021-05-29)
There is still limited understanding of how waters mix, where waters come from and for how long they reside in tropical catchments. In this study, we used a tracer-aided model (TAM) and a gamma convolution integral model ...
Stable isotopic characterizacion of nitrate wet deposition in the tropical urban atmosphere of Costa Rica
(Springer, 2021-07-13)
Increasing energy consumption and food production worldwide results in anthropogenic emissions of reactive nitrogen into the atmosphere. To date, however, little information is available on tropical urban environments where ...
Stable isotopic characterization of nitrate wet deposition in the tropical urban atmosphere of Costa Rica
(Research Square, 2021)
Increasing energy consumption and food production worldwide results in anthropogenic emissions of reactive nitrogen into the atmosphere. To date, however, little information is available on tropical urban environments where ...
