Abstract

This study analyses spatial and temporal variations in temperture, salinity, silicate and orthophosphate in the water of Tampamachoco lagoon, Veracruz (México), from 1979 to 1986. Multivariate analysis was applied to distinguish water types during the three climatic seasons of the region. Principal components analysis defined three areas in the lagoon: (1) and estuarine-marine area characterized by a low content of silicates (3.37 to 5.44 ug-at/I), (2) an intermediate area that makes up the main body of the lagoon with a strong temporal and spatial variation and a wide range of SiO3 concentrations (7.04 to 14.71 ug-at/I) and (3) the area of shallow inner lagoons with low levels of SiO3 (4 to 8.47 ug-at/I). These areas varied during the three climatic seasons: nothers, dry and rainy season. The variation explained by silicate during the three seasons were 57%, 56% and 42%, respectively.
