Living: Earth and Ocean
Life evolved on Earth some 3.5 billion years ago and made major impacts on environmental conditions, which continue today. We study biogeochemical processes today and fossil inferences of their past roles.
Life on Earth has co-evolved with the planet and without life our environment would be very different: little oxygen, high CO2, high temperatures, highly reduced oceans, no oil or gas etc. Microbes drive many of the responsible biogeochemical cycles and we investigate the rates, controls, feedbacks and the organisms involved.
Rocks contain a unique archive of past ecosystems in their fossils, which we study to document the rich history of life on Earth and its environmental impact.
