Floodplains are dynamic ecosystems that cycle carbon, which is both delivered from upstream catchment sources and produced in-situ. These systems are being increasingly recognised as key environments of carbon processing, with the capacity for substa...

Comparison of the transformation of organic matter flux through a raised bog and a blanket bog (2023)
Journal Article
Glatzel, S., Worrall, F., Boothroyd, I. M., & Heckman, K. (2024). Comparison of the transformation of organic matter flux through a raised bog and a blanket bog. Biogeochemistry, 167(4), 443-459. https://doi.org/10.1007/s10533-023-01093-0

This study has proposed that organic matter transfer and transformation into and through a peatland is dominated by preferential loss of carbohydrates and the retention of lignin-like molecules. Here we used elemental analysis and thermogravimetric a... Read More about Comparison of the transformation of organic matter flux through a raised bog and a blanket bog.

Chemical Oxygen Demand as a Measure of Fluvial Organic Matter Oxidation State (2023)
Journal Article

The oxidative ratio (OR) of the terrestrial biosphere is directly related to the size of the terrestrial biosphere carbon sink. In turn, OR of naturally occurring organic matter can be directly related to the oxidation state of the carbon in naturall...

Dissolved inorganic carbon (DIC) fluxes from the land to ocean have been quantified for many rivers globally. However, CO2 fluxes to the atmosphere from inland waters are quantitatively significant components of the global carbon cycle that are curre...

River water temperature demonstrates resistance to long‐term air temperature change (2022)
Journal Article

Ecosystem health and water quality of rivers are dependent on their temperature. With ongoing human-induced climate change causing increases in air temperature across the globe, it is anticipated the stream temperatures will rise too—in turn increasi...
