Summary: | The goal of this study was to verify the utility and accuracy of two tools to obtain a bathymetric chart for Lagoa Central (Lagoa Santa, State of Minas Gerais, Brazil) and also to assess the morphometric parameters of the lake and their implications in the ecology of this system. The tested tools were the Biosonics DT-X (Biosonics Inc.) echosounder and the SonarLite (Ohmnex Ltda) bathymeter, both coupled to a Differential Global Positioning System (DGPS) to obtain the geographic coordinates associated with the depth in each point. Lagoa Central is a small, shallow (Zmax < 7.5 m), with low relative depth values (Zr = 0.5%) and concave. This makes the water body less prone to thermal stratification and more susceptible to eutrophication. Both investigated equipments demonstrated to be suitable for the survey, user-friendly, low-cost and with sub-metric accuracy. |

Numa segunda etapa, o estudo estimou todos os parâmetros morfométricos primários e secundários desse ambiente. Finalmente, o estudo avaliou a importância dessas informações na qualidade de água e na ecologia geral do sistema. Os protocolos foram baseados no uso de dois sistemas distintos, usados para o levantamento batimétrico: uma ecossonda Biosonics DT-X (Biosoncs Inc.) e um Ecobatímetro SonarLite (Ohmnex Ltda), ambos acoplados a um D-GPS (Differential Global Positioning System) para a obtenção das coordenadas geográficas de cada profundidade medida. A Lagoa Central de Lagoa Santa é um pequeno lago natural, raso (Zmax < 7,5 m), com profundidade relativa baixa (Zr = 0,5%) e formato côncavo. Essas características a tornam menos propensa à formação de estratificação térmica estável e, portanto, menos sensível à formação de gradientes químicos verticais na coluna de água. Essa configuração pode ser vista como um dos fatores principais que impedem o agravamento do processo de eutrofização verificado nesse sistema.Universidade Estadual De Maringá2011-04-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciBiolSci/article/view/554510.4025/actascibiolsci.v33i3.5545Acta Scientiarum.
