Abstract

The Tucurui reservoir was formed by damming the Tocantins river and flooding around 2430 Km² of forest land. Its average depth is 18 meters with a dendritic shoreline which is responsible for a large variety of water masses with distinctive properties. This aquatic system therefore offers an unique opportunity for collection of wide variety of spectral data representative of the conditions usually found in Amazon reservoirs. These could be used as an spectral library for interpretation of imaging spectrometric data. This paper reports an experiment performed in April 1992 in which spectrometric data were collected over the Tucurui reservoir concurrently to water sampling at surface, at 50% light penetration depth, and at Secchi depth. Water samples were analyzed to obtain chlorophyll pigment, total suspended solids concentration and yellow substance attenuation. The preliminary results show two different types of optical waters, influenced mainly by total suspended solids concentration.
