Tyler Mackey

Tyler Mackey is a sedimentary geobiologist and his research centers on how microbial ecosystems are preserved in the sedimentary record. Tyler's work includes field studies in perennially ice-covered lakes of the McMurdo Dry Valleys, Antarctica, where thick microbial mats cover the lake bottom. Microbial mat organic matter, sediments, and carbonate mineral precipitates together provide a rich record of ecosystem function under perennial ice and evidence for how these environments have been changing with climate in the region.
