This sheet contains data on calculated power from the oxidation of biomolecules with oxygen at South Pacific Gyre (hole U1370, IODP Expedition 329). 

This project quantifies the role of microbial necromass and organic carbon as a power source to living microorganisms in marine sediments. The project utilizes a physiochemical model of marine sediment bioenergetics using data available in the literature and well-established modeling constructs. Data sources and model formulation are described in Bradley et al. 2018 (DOI: 10.1002/2017JG004186). For modelling South Pacific Gyre sediments, cell abundance and particulate organic carbon concentrations were determined for site U1370 (IODP Expedition 329) based on published analysis of extracted drill cores: D’Hondt et al. 2015 (DOI: 10.1038/ngeo2387); D’Hondt et al. 2011 (DOI: 10.2204/iodp.proc.329.2011). For modelling global cell abundance, we use the formulation described in Parkes et al. 2014 (DOI: 10.1016/j.margeo.2014.02.009).
