NC10 bacteria in marine oxygen minimum zones
(2016-08-10)
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 ...

Changes in mangrove coverage in Culebra Bay, North Pacific of Costa Rica (1945-2010)
(2016)
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 ...
Análisis de datos de CTD de campañas oceanográficas recientes en el Pacífico Tropical del Este, Costa Rica
(2017)
Un CTD es un instrumento oceanográfico el cual permite medir la conductividad, temperatura y presión. Los datos producidos por un CTD permiten calcular otras variables como la salinidad. La información generada permite la ...
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.

Between 1990 and 1992, 2 adult specimens of the ventrad spiderfish, Bathypterois ventralis Garman 1899, were collected at depths between 637 and 880 m off the Pacific coast of Costa Rica. These specimens constitute the ...
Seasonal changes of the microplankton community along a tropical estuary
(2015-11)
Microplankton organisms are an important link in the transfer of matter and energy between the benthic–pelagic microbial food web and higher trophic levels in estuaries. Although tropical estuaries are among the most ...
Effects of Seasonal Upwelling on Inorganic and Organic Matter Dynamics in the Water Column of Eastern Pacific Coral Reefs
(2015-11)
The Gulf of Papagayo at the northern Pacific coast of Costa Rica experiences pronounced seasonal changes in water parameters caused by wind-driven coastal upwelling. While remote sensing and open water sampling already ...
Dynamics in benthic community composition and influencing factors in an upwelling-exposed coral reef on the Pacific coast of Costa Rica
(2015-11-24)
Seasonal upwelling at the northern Pacific coast of Costa Rica offers the opportunity to investigate the effects of pronounced changes in key water parameters on fine-scale dynamics of local coral reef communities. This ...
