Hyperspectral optical analysis of Zumpango Lake, Mexico

Abstract

This paper shows a hyperspectral optical analysis of Zumpango Lake, relict of one of the lakes that formerly filled the Mexico Basin. The spectral signatures are dominated by the presence of phytoplankton and submerged vegetation. Integrated spectral curves have a good statistical correlation with chlorophyll a concentration values. It indicates that submerged vegetation water, mainly hyacinth (Eichhornia spp) and duckweed (Lemna sp), and phytoplankton are homogeneously distributed in the water body, which confers it characteristics of eutrophication.
