Study of the movement of water masses and implications for greenhouse gas emissions in tropical aquatic ecosystems

Data: 10 de November de 2016

   The study of the movement of water bodies in lakes and reservoirs provides support for the understanding of physical, chemical and biological processes. The spatio-temporal variability of the measured parameters also responds strongly to hydrodynamics.

   Several water mass circulation processes occur frequently in aquatic environments, in response to external forcing — such as wind and solar radiation incidence. The motivations of this project come from the hydrodynamic complexity in limnic ecosystems, directly related to ecological processes and the emission of greenhouse gases .

   In this sense, our main goal is to understand the behavior of hydrodynamic and thermal physical forces of lakes and reservoirs, connected to rivers and controlling the balance of CO2 and CH4.

   Two ecosystems will be analyzed: an Amazonian lake with clear water and a reservoir of the Cerrado region. Hydrodynamic techniques associated with limnological measures and emissions of carbon dioxide and methane will be used.

   The present work will provide unprecedented knowledge on the circulation of water bodies and the characteristics of the thermal structure associated to the emission of gases in the two environments under study, in addition to generating a large limnological data base.
