Researchers will characterize microbial mats that are growing on the floor of Lake Joyce. Previous results demonstrate that these mats are morphologically similar to fossil mats that are 2.5 to 3 billion years old in diverse locations around the globe. They will use the living mats in Lake Joyce to develop a model for biological, sedimentological, and geochemical processes that influence microbial mat morphology and will use that model to help constrain processes influencing ancient mat growth.
