Earth’s core could be the largest terrestrial carbon reservoir

S. K. Baigain, M. Mookherjee, et al.

This study by Suraj K. Baigain, Mainak Mookherjee, and Rajdeep Dasgupta reveals that Earth's outer core might hold 0.3-2.0 wt.% carbon, making it potentially the largest terrestrial carbon reservoir. Discover how the researchers arrived at these findings through molecular dynamics simulations.

Abstract
This study uses first-principles molecular dynamics simulations to investigate the carbon content in Earth's core. By analyzing density and compressional wave velocity of liquid iron-carbon alloys, the researchers find that a carbon content of 0.3-2.0 wt.% in the outer core satisfies both seismological observations and density constraints. This suggests the outer core could be the largest terrestrial carbon reservoir.
