Nature publication
January 2023 - Our dear colleague Ziye is the first author of a new Nature publication. Together with scientists from the USA and UK, she analysed data from deep-sea drilling at 81 global sites to determine the history of organic carbon burial during the Neogene (23-3 Ma). Their results support the assumption that rates were high in the early Miocene & Pliocene and low in the middle Miocene. They assume that carbon sequestration is related to temperature-dependent bacterial decomposition of organic matter during the warm period of the middle Miocene. Follow the article and press release...
