Abstract:
This research investigated 39 cities in the Amazônia, with the purpose of showing the high temperatures of the waters of the Amazon River, using remote sensors (Global Positioning System - GPS and Globalnaya Navigatsionnaya Sputnikovaya System - GLONASS), besides digital weather station and ship navigation, as a contribution to the trends of the El Niño phenomenon in the Amazon. It collected information on water quality, weather and climate, georeferencing of the route and localities during a drought period on the Amazon River, from Iquitos in Peru, to the city of Macapá in Brazil (Atlantic Ocean) in 2016, all data are presented in tables and thematic maps. The results obtained with temporal temperature series, compared to satellite images of temperature gradients, georeferenced map and water quality analysis showed high water temperatures along the river during the entire observation period, probably due to the prolonged El Niño event in 2014, 15 and 16.
