High rates of rock organic carbon oxidation sustained as Andean sediment transits the Amazon foreland-floodplain (2023)
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.

Dissolved trace element concentrations and fluxes in the Irrawaddy, Salween, Sittaung and Kaladan Rivers (2022)
Journal Article
Bridgestock, L., Henderson, G. M., Holdship, P., Khaing, A. M., Naing, T. T., Myint, T. A., …Bickle, M. (2022). Dissolved trace element concentrations and fluxes in the Irrawaddy, Salween, Sittaung and Kaladan Rivers. Science of the Total Environment, 841, Article 156756. https://doi.org/10.1016/j.scitotenv.2022.156756

The Irrawaddy (Ayeyarwaddy) and Salween (Thanlwin) globally rank among the largest rivers for supplying dissolved and particulate material to the ocean. Along with the Sittaung and Kaladan rivers they have societal importance to Myanmar in terms wate...

Vegetal Undercurrents—Obscured Riverine Dynamics of Plant Debris (2022)
Journal Article
Schwab, M. S., Hilton, R. G., Haghipour, N., Baronas, J. J., & Eglinton, T. I. (2022). Vegetal Undercurrents—Obscured Riverine Dynamics of Plant Debris. Journal of Geophysical Research: Biogeosciences, 127(3), Article e2021JG006726. https://doi.org/10.1029/2021jg006726

Much attention has been focused on fine-grained sediments carried as suspended load in rivers due to their potential to transport, disperse, and preserve organic carbon (OC), while the transfer and fate of OC associated with coarser-grained sediments...

Constraints on the source of reactive phases in sediment from a major Arctic river using neodymium isotopes (2021)
Journal Article
Larkin, C. S., Piotrowski, A. M., Hindshaw, R. S., Bayon, G., Hilton, R. G., Baronas, J. J., …Tipper, E. T. (2021). Constraints on the source of reactive phases in sediment from a major Arctic river using neodymium isotopes. Earth and Planetary Science Letters, 565, Article 116933. https://doi.org/10.1016/j.epsl.2021.116933

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...

Freshwater monitoring by nanopore sequencing (2021)
Journal Article
Urban, L., Holzer, A., Baronas, J. J., Hall, M. B., Braeuninger-Weimer, P., Scherm, M. J., …Stammnitz, M. R. (2021). Freshwater monitoring by nanopore sequencing. eLife, 10, https://doi.org/10.7554/elife.61504

While traditional microbiological freshwater tests focus on the detection of specific bacterial indicator species, including pathogens, direct tracing of all aquatic DNA through metagenomics poses a profound alternative. Yet, in situ metagenomic wate... Read More about Freshwater monitoring by nanopore sequencing.

Modulation of Riverine Concentration‐Discharge Relationships by Changes in the Shape of the Water Transit Time Distribution (2021)
Journal Article
Torres, M. A., & Baronas, J. J. (2021). Modulation of Riverine Concentration‐Discharge Relationships by Changes in the Shape of the Water Transit Time Distribution. Global Biogeochemical Cycles, 35(1), Article e2020GB006694. https://doi.org/10.1029/2020gb006694

The concentrations of weathering-derived solutes in rivers and their covariance with discharge are thought to reflect reactive-transport processes in hillslopes and to reveal the sensitivity of solute fluxes to climatic change. It is expected that di... Read More about Modulation of Riverine Concentration‐Discharge Relationships by Changes in the Shape of the Water Transit Time Distribution.

Global silicate weathering flux overestimated because of sediment–water cation exchange (2020)
Journal Article
Tipper, E. T., Stevenson, E. I., Alcock, V., Knight, A. C. G., Baronas, J. J., Hilton, R. G., …Hughes, G. (2021). Global silicate weathering flux overestimated because of sediment–water cation exchange. Proceedings of the National Academy of Sciences, 118(1), Article e2016430118. https://doi.org/10.1073/pnas.2016430118

Large rivers transport water and sediment to floodplains and oceans, supplying the nutrients that sustain life. They also transport carbon, removed from the atmosphere during mineral dissolution reactions, which is thought to provide a key negative c...
