Evaluación de modelos numéricos de Tercera Generación para el pronóstico del oleaje en Centroamérica y México
The evaluation and implementation of two public domain wave spectral models: SWAN and WAM to be used in hindcasting and forecasting in the Central American region are presented. The typical model characteristics are analyzed ...
Un método para evaluar el enriquecimiento de metales en sedimentos marinos en Costa Rica
(Revista Biología Tropical 60 (2): 197-211, 2012-04-01)
A method to evaluate metal enrichment in marine sediments. In order to evaluate metal enrichment in sediments , a method is proposed and tested in Bahia Culebra and the Golfo de Nicoya, Costa Rica through the normalization ...
Arrecifes latinoamericanos bajo amenazas comunes
(Revista Crisol, n. 12, p. 15-17, 2004, 2004)
Aunque tienen características propias que los distinguen unos de otros, los arrecifes coralinos del Mar Caribe, de Brasil y del Pacífico Americano corren el riesgo de desaparecer por problemas comunes.
NC10 bacteria in marine oxygen minimum zones
Bacteria of the NC10 phylum link anaerobic methane oxidation to nitrite denitrification through a unique O2-producing intra-aerobic methanotrophy pathway. A niche for NC10 in the pelagic ocean has not been confirmed. We ...
One year weekly dynamics of limnological conditions and phytoplankton in Lake Bonilla, Costa Rica
The detailed response of tropical lake phytoplankton to weather variations has been little studied, but it seems that composition varies in response to rain and wind variability over the course of the year. In order to ...
Interannual variability of the midsummer drought in Central America and the connection with sea surface temperatures
The midsummer drought (MSD) in Central America is characterised in order to create annual indexes representing the timing of its phases (start, minimum and end), and other features relevant for MSD forecasting such as the ...
Variability of the Caribbean low-level jet during borealwinter: large-scale forcings
An index capturing the anomalies of the zonal wind at 925 hPa from 1950 to 2010 was defined to explore the relationship between the fluctuations of the Caribbean low-level jet (CLLJ) and the main climate variability modes ...
Cambios en la cobertura de manglares en Bahía Culebra, Pacífico Norte de Costa Rica (1945-2010)
Changes in mangrove coverage in Culebra Bay, North Pacific of Costa Rica (1945-2010)
Los manglares tienen gran importancia ecológica, económica, riqueza natural y prestan servicios ambientales. No obstante, son amenazados por la sobreexplotación, la contaminación y el cambio de uso de suelo. Costa Rica ...
Importance of differentiating Orbicella reefs from gorgonian plains for ecological assessments of Caribbean reefs
Region-wide assessments of coral cover typically rely on meta-analyses of small-scale ecological studies which have combined different coral reef habitats. This is particularly problematic on forereefs where at least 2 ...
Simulated overfishing and natural eutrophication promote the relative success of a non-indigenous ascidian in coral reefs at the Pacific coast of Costa Rica
Colonial ascidians of the genus Didemnum are common fouling organisms and are typically associated with degraded ecosystems and anthropogenic structures installed in the sea. In this study, however, the non-indigenous ...
