Supporting Information for Bacterial magnetofossil evidence for enhanced Pacific Ocean respired carbon storage during buildup of Antarctic glaciation.

This document provides supporting information for an article titled "Bacterial magnetofossil evidence for enhanced Pacific Ocean respired carbon storage during buildup of Antarctic glaciation." It includes details of materials and studied sites, magnetic and geochemical analytical methods, model configuration and boundary conditions for climate simulation experiments, sea-ice fraction simulation results, the age model adopted for the studied sites, parameters associated with components identified from isothermal remanent magnetization (IRM) unmixing analysis, and the BH/BS ratio from TEM results and IRM unmixing. The study collected sediment samples from two sites in the eastern equatorial Pacific Ocean to trace deep Pacific Ocean deoxygenation and its relation to Southern Ocean production variations. Magnetic and geochemical measurements were performed to analyze the sediment samples. This document provides information on sediment ages and climate simulation experiments. Sediment ages were determined using a revised age model, and various fluxes were calculated based on the mass accumulation rate. Climate simulations were conducted using the Community Earth System Model, which consists of multiple components that interact with each other. The simulations were based on the climate state at 35 million years ago and included factors such as vegetation distribution, orbital conditions, and CO2 concentrations. The document also includes figures and tables with additional data and results. The given text appears to be a compilation of data tables and references related to various scientific studies and research papers. The tables include numerical values and ratios related to different samples and measurements. The references provide sources for further reading [Extracted from the article]
