IcebergAlley.jpegThe oceans play a crucial role in the regulation of Earth’s climate. Faculty in UGA Marine Sciences study how changes to the Earth’s climate affects the oceans as well as how the oceans affect the climate of the planet. These studies take place across the globe, from the Arctic to the Antarctic and places in between; they cover the global to the regional scale, with investigations of how sea level rise affects coastal systems to how microbial processes regulate planetary climate. In undertaking this research, UGA faculty use tools from chemical, biological, geological and physical oceanography and combine field observations with computer models to provide a fully interdisciplinary approach.
