Glacial Environments

Modern remote sensing data from the Antarctic subglacial environment reveal an active hydrologic system where water is stored in lakes and saturated sediments and is flushed towards the ice sheet margin during flooding events. These aqueous systems help regulate ice sheet flow and are significant sources of ocean solutes and nutrients. However, there is currently no geologic evidence for how the Antarctic basal hydrologic system evolves through time. My research applies geochronological, geochemical, and textural analyses of subglacial precipitates to study past subglacial flooding in Antarctica.

Subglacial Hydrology

Modern remote sensing data from the Antarctic subglacial environment reveal an active hydrologic system where water is stored in lakes and saturated sediments and is flushed towards the ice sheet margin during flooding events. These aqueous systems help regulate ice sheet flow and are significant sources of ocean solutes and nutrients. I am working on a establishing long-term records for subglacial flushing beneath the East Antarctic Ice Sheet.
