The influence of Antarctic subglacial volcanism on the global iron cycle during the Last Glacial Maximum

Contributions of iron sources to Southern Ocean CO2sequestration during the last glacial period remain uncertain. Here, based on the biogeochemical analysis of subglacial calcites, the authors propose Antarctic volcanism, via subglacial drainage of Fe-rich waters, as a key contributor.
