Journal Article
Dellinger, M., Hilton, R. G., Baronas, J. J., Torres, M. A., Burt, E. I., Clark, K. E., …West, A. J. (2023). High rates of rock organic carbon oxidation sustained as Andean sediment transits the Amazon foreland-floodplain. Proceedings of the National Academy of Sciences, 120(39), Article e2306343120. https://doi.org/10.1073/pnas.2306343120

The oxidation of organic carbon contained within sedimentary rocks (“petrogenic” carbon, or hereafter OCpetro) emits nearly as much CO2 as is released by volcanism, thereby playing a key role in the long-term global C budget. High erosion rates in mo... Read More about High rates of rock organic carbon oxidation sustained as Andean sediment transits the Amazon foreland-floodplain.

Constraints on the source of reactive phases in sediment from a major Arctic river using neodymium isotopes (2021)
Journal Article

Riverine suspended particulate matter (SPM) is essential for the delivery of micronutrients such as iron (Fe) to the oceans. SPM is known to consist of multiple phases with differing reactivity, but their role in the delivery of elements to the ocean...

A large portion of freshwater and sediment is exported to the ocean by a small number 22 of major rivers. Many of these mega-rivers are subject to substantial anthropogenic pres23 sures, which are having a major impact on water and sediment delivery...
