Microbiologist Karen Lloyd (DCO Executive Committee, University of Tennessee Knoxville, USA) takes us on a trip to the volcanoes and hot springs of Costa Rica, shining a light on subterranean organisms and how they could have a profound impact on life at Earth's surface.
Dr. Lloyd studies novel groups of microbes in Earth's deep surface biosphere, collecting them from disparate remote places such as Arctic fjords, volcanoes in Costa Rica, even deep in mud in the Marianas Trench. She has adapted novel techniques to quantify and characterize these mysterious microbes, with minimal disruption to natural conditions. Her work centers on deep oceanic subsurface sediments, deep-sea mud volcanoes and cold seeps, terrestrial volcanoes and hot springs, serpentinizing springs, Arctic marine fjord sediments, and ancient permafrost.
This talk was presented in April at TED2019 in Vancouver, Canada.
