Magnetotactic bacterial response to Antarctic dust supply during the Palaeocene-Eocene thermal maximum

Larrasoana, Juan; Roberts, Andrew; Chang, Liao; Schellenberg, Stephen A; Fitz Gerald, John; Norris, Richard D; Zachos, James


Distinct magnetic properties of marine sediments that record the Palaeocene-Eocene thermal maximum (PETM) have been suggested to be due to a bacterial magnetofossil signal that is linked to enhanced weathering conditions during the PETM. We document the dominance of bacterial magnetite in deep-sea sediments from southern Kerguelen Plateau (Ocean Drilling Program Hole 738C, southern Ocean) not only during the PETM, but also before and after the thermal event. This occurrence of magnetofossils...[Show more]
