Abstract

ABSTRACT Lopez-Portillo, J.; Lara-Dominguez, A.L.; Vazquez, G., and Ake-Castillo, J.A., 2017. Water quality and mangrove-derived tannins in four coastal lagoons from the Gulf of Mexico with variable hydrological dynamics In: Martinez, M.L.; Taramelli, A., and Silva, R. (eds.), Coastal Resilience: Exploring the Many Challenges from Different Viewpoints. Journal of Coastal Research, Special Issue No. 77, pp. 28–38. Coconut Creek (Florida), ISSN 0749-0208. This study explored the spatial variability of physico-chemical water variables (i.e., salinity, nitrogen, phosphorus and tannins) in contrasting seasons in four coastal lagoons (Chica y Grande, La Mancha, Sontecomapan and El Ostion) along Veracruz state, Mexico. We also calculated the mangrove and central basin water areas and associated them to physico-chemical data to analyze them by means of Principal Component Analysis (PCA) due to high correlation among variables. Finally, we elaborated coded maps of each lagoon to represent the gradients of the vari...
