A humid corridor across the Sahara for the migration of early modern humans out of Africa 120,000 years ago (2008)
Journal Article
Osborne, A. H., Vance, D., Rohling, E. J., Barton, N., Rogerson, M., & Fello, N. (2008). A humid corridor across the Sahara for the migration of early modern humans out of Africa 120,000 years ago. Proceedings of the National Academy of Sciences of the United States of America, 105(43), 16444-16447. https://doi.org/10.1073/pnas.0804472105

It is widely accepted that modern humans originated in sub-Saharan Africa ≈150-200 thousand years ago (ka), but their route of dispersal across the currently hyperarid Sahara remains controversial. Given that the first modern humans north of the Saha... Read More about A humid corridor across the Sahara for the migration of early modern humans out of Africa 120,000 years ago.

New insights into biological influence on the geochemistry of freshwater carbonate deposits (2008)
Journal Article
Rogerson, M., Pedley, H. M., Wadhawan, J. D., & Middleton, R. (2008). New insights into biological influence on the geochemistry of freshwater carbonate deposits. Geochimica et cosmochimica acta, 72(20), 4976-4987. https://doi.org/10.1016/j.gca.2008.06.030

Ambient temperature freshwater carbonates ("tufas") have outstanding potential as palaeoclimate archives. However, it has proven difficult to constrain the behaviour of the geochemical parameters on which important proxy systems rely. Current thinkin...

A dynamic explanation for the origin of the western Mediterranean organic-rich layers (2008)
Journal Article
Rogerson, M., Cacho, I., Jimenez-Espejo, F., Reguera, M. I., Sierro, F. J., Martinez-Ruiz, F., Frigola, J., & Canals, M. (2008). A dynamic explanation for the origin of the western Mediterranean organic-rich layers. Geochemistry, Geophysics, Geosystems, 9(7), n/a-n/a. https://doi.org/10.1029/2007gc001936

The eastern Mediterranean sapropels are among the most intensively investigated phenomena in the paleoceanographic record, but relatively little has been written regarding the origin of the equivalent of the sapropels in the western Mediterranean, th...
