The Toarcian Oceanic Anoxic Event (T-OAE, ∼183 Ma) was characterized by enhanced carbon burial, a prominent negative carbon-isotope excursion (CIE) in marine carbonate and organic matter, and numerous geochemical anomalies. A precursor excursion has... Read More about The wider context of the Lower Jurassic Toarcian oceanic anoxic event in Yorkshire coastal outcrops, UK.

Journal Article
Horan, K., Hilton, R., Selby, D., Ottley, C., Gröcke, D., Hicks, M., & Burton, K. (2017). Mountain glaciation drives rapid oxidation of rock-bound organic carbon. Science Advances, 3(10), Article e1701107. https://doi.org/10.1126/sciadv.1701107

Over millions of years, the oxidation of organic carbon contained within sedimentary rocks is one of the main sources of carbon dioxide to the atmosphere, yet the controls on this emission remain poorly constrained. We use rhenium to track the oxidat... Read More about Mountain glaciation drives rapid oxidation of rock-bound organic carbon.

Evidence for rapid weathering response to climatic warming during the Toarcian Oceanic Anoxic Event (2017)
Journal Article

Chemical weathering consumes atmospheric carbon dioxide through the breakdown of silicate minerals and is thought to stabilize Earth’s long-term climate. However, the potential influence of silicate weathering on atmospheric pCO2 levels on geological...

Journal of Archaeological Science: Reports, 14, 575-579. https://doi.org/10.1016/j.jasrep.2017.06.042

Little is known about arable agriculture in the Early Neolithic (4000–3300 cal BC, Funnel Beaker Culture) of Southern Scandinavia. Archaeobotanical material is rare and few archaeological sites have yielded more than a small number of charred cereal...

Nitrogen stable isotope ratios (δ15N) in macroalgae are often used to identify sources of nitrogenous pollution in fluvial and estuarine settings. This approach assumes that the macroalgal δ15N is representative of the sources of the pollution averag...
