Integrating proxy and model estimates of oceanographic variability and change in the Ross Sea, Antarctica from the Mid-Holocene (6 ka) to present
Integrating proxy and model estimates of oceanographic variability and change in the Ross Sea, Antarctica from the Mid-Holocene (6 ka) to present
Today, warm (~1˚C) Circumpolar Deep Water (CDW) upwelling along the Antarctic margin threatens the stability of the ice sheet. However, the ~40 yr observational period routinely used to develop and evaluate predictive models is too short to characterize the complex oceanography at the ice-ocean interface and capture the natural variability of the Antarctic and Southern Ocean climate system prior to anthropogenic influence. The aim of my PhD is to combine the strengths of high-resolution paleoceanographic reconstructions and numerical ocean models by integrating 6,000 yr sedimentary records of Ross Sea Holocene oceanography with a regional ROMS model.

Why do you do what you do?
I study Antarctica because ever since my first introductory geology course I've been fascinated by the way the Earth's climate evolves through time. Today, my concern about the future we're creating in the 21st century fuels that original sense of curiosity and wonder.
