This paper reports new geochemical data on dissolved major and minor constituents in surface waters and ground waters collected in the Managua region (Nicaragua), and provides a preliminary characterization of the hydrogeochemical processes governing the natural water evolution in this area. The peculiar geological features of the study site, an active tectonic region (Nicaragua Depression) characterized...
From 1987 to 1993 we assessed the variation of phytoplankton biomass, underwater irradiance and primary production in Lake Xolotlán (L. Managua, Nicaragua). Chlorophyll- a averaged 65 mg m-3 and maximum and minimum concentrations were 120 and 30 mg m-3, respectively. The variability over depths and weeks was low (CV < 20%). There were strong correlations between particulate carbon and chlorophyll-...
