Dr. Tyler Mackey, Department of Earth and Planetary Sciences, University of New Mexico

Perennially ice-covered lakes serve as liquid water oases in Antarctic polar deserts. Lake beds are covered with thick microbial mats where enough light penetrates for seasonal photosynthetic activity, and patterns of mat growth are a product of the relationship between microbial activity and the surrounding environment. In this seminar, Dr. Mackey will present an overview of the microbial landscapes found on the Antarctic lake beds and how their accumulated layers provide an important record of ecosystem response to changing regional climate.
