My research within C-DEBI is motivated by the quest to determine and understand activity levels among microbial communities in the marine subsurface in relation to their geochemical and physical environment. To this end, in collaboration with Doug LaRowe and Jan Amend (USC), I developed novel modelling frameworks based on thermodynamic and microbial-modelling principles to explore and quantify: The energy sources to deeply buried microorganisms and their demand for energy. The activity of microorganisms and the factors that determine physiological transitions between active and dormant states. The varying energy requirements of active and dormant microbes and the allocation of energy between maintenance and growth. The cell-specific energy utilization (i.e. power) of subsurface life on a global scale. I led the development of a new freely-available and open-source platform MicroLow 1.0 ? a process-based microbial model that explicitly considers physiological state transitions and energy for maintenance and growth. Using this model, I showed that energetic efficiency provides a selective advantage for long-term microbial survival in oligotrophic marine sediments. Numerous additional opportunities have arisen thanks to the C-DEBI program and community, including participation in two collaborative workshops (organic carbon preservation, impacts of deep sea mining), numerous valuable interactions, ongoing collaborations and spin-off projects, presentations at international conferences, professional development opportunities, media exposure, complementary funding including a Deep Carbon Observatory DLMV Fellowship, significant widening of my professional network, fieldwork opportunities, and career progression."; String projects_0_end_date "2019-03"; String projects_0_name "Develop a 1D biogeochemical-evolutionary model for deep sediments"; String projects_0_project_nid "776336"; String projects_0_project_website "https://www.darkenergybiosphere.org/award/develop-a-1d-biogeochemical-evolutionary-model-for-deep-sediments/"; String projects_0_start_date "2016-10"; String publisher_name "Biological and Chemical Oceanographic Data Management Office (BCO-DMO)"; String publisher_type "institution"; String sourceUrl "(local files)"; Float64 Southernmost_Northing -41.85; String standard_name_vocabulary "CF Standard Name Table v55"; String subsetVariables "latitude,longitude"; String summary "Calculated power from the oxidation of necromass that is produced in marine sediment on a global scale."; String title "[global] - Calculated power from the oxidation of necromass that is produced in marine sediment on a global scale.
