Dr. Samantha (Mandy) Joye is the Athletic Association Professor in Arts and Sciences in the Department of Marine Sciences in the University of Georgia's Franklin College of Arts and Sciences. She is an expert in biogeochemistry and microbial ecology and works in open ocean and coastal ecosystems. Her work is interdisciplinary, bridging the fields of chemistry, microbiology, and geology.
Dr. Joye's research has been widely published in leading scientific journals, and she is regularly called upon by national and international scientific and policy agencies for expert commentary. Her work has been funded by substantial, multi-year grants from the National Science Foundation, the Environmental Protection Agency, the Gulf of Mexico Research Institute, and the National Oceanic and Atmospheric Administration, among others.

The oceans cover 71% of the Earth’s surface. Certain aspects of ocean circulation, element distributions, and biological activity are changing at unprecedented rates. This course provides an introduction to basic oceanography and presents an overview of some of the key local, regional, and global scale changes occurring in the ocean. We will also discuss the potential impacts of these changes and what can be done to reverse present trends. Undergraduate level
Emphasizes the roles of microorganisms in ecosystems. Nutrient cycles, methods of microbial analysis, and the functional roles of microorganisms. Undergraduate level
Emphasizes the roles of microorganisms in ecosystems. Nutrient cycles, methods of microbial analysis, and the functional roles of microorganisms. Graduate level
Microbial processes influence all aspects of the Earth, ranging from atmospheric composition to elemental cycling in the deep biosphere. This course describes the interaction of biology with geologic, environmental, and climate change processes throughout Earth history and provides a broad understanding of the history of life on Earth.
