School of Earth and Atmospheric Sciences Undergraduate Research Option Theses
The Research Option offers students majoring in earth and atmospheric sciences the opportunity for a substantial, in-depth research experience. Students are strongly encouraged at the end of their experience to work with their faculty mentor to develop a journal publication or conference presentation on the research in addition to the actual thesis.

Characterizing iron reducing microorganisms from anoxic ferruginous lake sediments
Lake Matano, Indonesia is a well-known ancient ocean analogue as its anoxic ecosystem in the subsurface sediments allow the growth of microorganisms capable of mediating anaerobic oxidation coupled to iron reduction. An ... -
Earth's oxygen and phosphorus cycle and the evolution of animal life
The purpose of this study is to reconstruct an environmental context for the emergence and expansion of early animal life during the Middle Proterozoic (∼1.8–0.8 billion years ago). Specifically, we examined the spatially ... -
Transport Pathways of Shelf Source Micronutrients to the Southern Ocean
(Georgia Institute of Technology, 2015-08-18)We use a numerical ocean model to evaluate the hypothesis that the continental shelves are significant sources of dissolved iron to the Southern Ocean. We simulate the distribution of passive tracers released from the 18 ... -
Measuring present-day strain rates along the Fish Lake Valley fault system, Pacific-North America plate boundary
(Georgia Institute of Technology, 2012-05-07)The eastern California shear zone (ECSZ) is located east of the San Andreas fault and contains a complex network of structures that accommodate ~25% of the relative displacement between the Pacific and North American plates. ... -
Stream Terraces in the Critical Zone - Lower Gordon Gulch, Colorado
(Georgia Institute of Technology, 2011-05-09)As bedrock weathers into soil, erosional processes often carry loose sediment down slope into a stream channel. Higher weathering rates produce larger amounts of erodible soil, which then causes sediment in the stream to ... -
Modeling energetic-charged particles within the Europa-Jupiter environment
(Georgia Institute of Technology, 2011-05-09)Europa, one of Jupiter's Galilean moons, is one of the few planetary bodies in our solar system thought to have the prospect of life. The Jupiter-Europa Orbiter (JEO), part of a new flagship mission, will be sent to the ... -
The Role of Iron Oxides in Marine Phosphorus Cycling
(Georgia Institute of Technology, 2009-05-04)Dissolved and particulate phase iron (Fe) and phosphorus (P) concentrations were characterized in Effingham Inlet, a fjord located on the west coast of Vancouver Island. The effect of redox conditions on Fe and P cycling ...
