'Organic carbon burial' by Dr. Sandra Arndt


Dr. Sandra Arndt's short biography:

Sandra Arndt obtained her Diplom (Msc equivalent) in Marine Environmental Sciences in 2004 at the Carl-von-Ossietzky Universitaet Oldenburg (Germany), and her PhD in Geosciences in 2008 at Utrecht University (The Netherlands). After completing her PhD, she worked as a postdoctoral research fellow at the CNRS, LMTG Observatoire Midi-Pyrenees (France) and Utrecht University (Netherlands). Since 2010, she works as a NERC fellow at the School of Geographical Sciences at the University of Bristol, where she also holds an assistant professor position since 2012.
Her research focuses on the development and application of models that are designed to advance our understanding of global biogeochemical dynamics and elucidate the environmental controls on past, present and future carbon cycling and climate. She is particularly interested in the diagenetic transformations and the burial of carbon in marine sediments on different spatial and temporal scales and its impact on global biogeochemical cycles and climate. In addition, she also studies the biogeochemical dynamics of the land-ocean continuum and the influence of the estuarine filter on carbon and nutrient fluxes.

Lecture's abstract - 'Organic carbon burial':

This lecture will shed light onto the important role of organic carbon burial in the Earth's climate system. It will provide a general overview of the process interplay that controls organic carbon burial in sediments and will critical review its description in biogeochemical and Earth System models. In addition, it will evaluate organic carbon burial estimates, as well as their uncertainties and highlight hotspots of carbon burial in both the present-day ocean, as well as over geological timescales.
