Abstract

The Pantanal wetlands are characterized by various types of alkaline or freshwater lakes. Previous studies have shown that small variations in a lake alkalinity level can lead to a high reactivity and significant changes in the production of greenhouse gases. To quantify the greenhouse gases emission of the Pantanal, it is therefore necessary to know the spatial and temporal distribution of the different types of lake. Remote sensing data obtained by different types of sensor can be applied, in order to separate the Pantanal lakes and to categorize them according to their alkalinity, amount of suspended organic matter, occurrence of vegetal biomass and degree of connection with the major drainage system. The project objective is to use remote sensing imagery obtained by passive (hyperspectral and multispectral) and active (SAR) sensor systems, in dry and wet seasons of the Nhecolândia area of the Pantanal. After acquisition and preprocessing of remote sensing data, a multisensor approach will be used to differentiate the lake types, to model the lake surface temperatures, to characterize their geomorphological surroundings and to group them according to the level of connectivity with the major drainage system.
