Fluid geochemistry and seismic activityin the period 1998-2002 at Turrialba Volcano (Costa Rica)
volcanic gases volcanic hazard geochemical monitoring geophysical monitoring Turrialba Volcano
2015/9/15
Turrialba Volcano, located in Central-Southern Costa Rica, has been characterized, since the last period of eruptive activity in 1884-1886, by a weak and discontinuous fumarolic activity in the wester...
Water chemistry and soil radon survey at the Poas volcano (Costa Rica)
Poas volcano geochemistry radon precursor
2015/9/10
Radon-in-soil monitoring at the Poas volcano (Costa Rica) has been performed together with water chemistry
from the hot crater lake since 1981 and 1983 respectively. The results are discussed as a fu...
Characterisation of the magmatic signature in gas emissions from Turrialba Volcano, Costa Rica
Volcanic gases superposition lava shallow hydrothermal system magma volcanic gases magma
2015/1/6
The equilibrium composition of volcanic gases with their magma is often overprinted by interaction with a shallow hydrothermal system. Identifying the magmatic signature of volcanic gases is critical ...
Fine spatial structure of genetically distinct picocyanobacterial populations across environmental gradients in the Costa Rica Dome
Fine spatial structure genetically distinct picocyanobacterial populations across environmental gradients in the Costa Rica Dome
2014/4/2
We investigated the spatial variability of picocyanobacterial community structure across the Costa Rica Dome(CRD), an offshore upwelling system characterized by high seasonal abundance of Synechococcu...
Monitoring of temporal and spatial variations in fumarole helium and carbon dioxide characteristics at Poás and Turrialba volcanoes, Costa Rica (2001-2009)
helium isotopes carbon isotopes Central America Costa Rica volcano monitoring
2017/8/9
We report results of a 9-year monitoring program that took place from 2001 to 2009 of the helium and carbon isotope (3He/4He, δ13C) and relative abundances ratios (CO2/3He) of fumarole sites at Poás a...
Response of the Eastern Tropical Pacific to Meridional Migration of the ITCZ：The Generation of the Costa Rica Dome
Eastern Tropical Pacific Meridional Migration Costa Rica Dome
2008/12/23
A regional ocean circulation model with fine horizontal resolution has been developed in order to obtain a coherent seasonal picture of the eastern tropical Pacific off Central America.
The Costa R...
Production of cobalt binding ligands in a Synechococcus feature at the Costa Rica upwelling dome
cobalt binding ligands Synechococcus feature Costa Rica upwelling dome
2014/5/8
The Costa Rica upwelling dome (CRD; ~8.67°N and 90.6°W) was characterized chemically for cobalt and nickel abundances and speciation and biologically using cyanobacterial abundances and phylogeny. Tot...
