An 80-million-year sulphur isotope record of pyrite burial over the Permian–Triassic (2022)
Journal Article
Salisbury, J., Gröcke, D. R., Cheung, H. A., Kump, L. R., McKie, T., & Ruffell, A. (2022). An 80-million-year sulphur isotope record of pyrite burial over the Permian–Triassic. Scientific Reports, 12, https://doi.org/10.1038/s41598-022-21542-4

Despite the extensive use of sulphur isotope ratios (δ34S) for understanding ancient biogeochemical cycles, many studies focus on specific time-points of interest, such as the end-Permian mass extinction (EPME). We have generated an 80 million-year P... Read More about An 80-million-year sulphur isotope record of pyrite burial over the Permian–Triassic.

A new subsurface record of the Pliensbachian-Toarcian, Lower Jurassic, of Yorkshire (2022)
Journal Article
Trabucho-Alexandre, J., Gröcke, D., Atar, E., Herringshaw, L., & Jarvis, I. (2022). A new subsurface record of the Pliensbachian-Toarcian, Lower Jurassic, of Yorkshire. Proceedings of the Yorkshire Geological Society, 64(2), https://doi.org/10.1144/pygs2022-007

Here, we describe the upper Pliensbachian to middle Toarcian stratigraphy of the Dove's Nest borehole, which was drilled near Whitby, North Yorkshire, in 2013. The core represents a single, continuous vertical section through unweathered, immature Lo... Read More about A new subsurface record of the Pliensbachian-Toarcian, Lower Jurassic, of Yorkshire.

Scotland’s first farmers: new insights into early farming practices in north-west Europe (2022)
Journal Article
Bishop, R., Gröcke, D., Ralston, I., Clarke, D., Lee, D., Shepherd, A., Thomas, A., Rowley-Conwy, P., & Church, M. (2022). Scotland’s first farmers: new insights into early farming practices in north-west Europe. Antiquity, 96(389), https://doi.org/10.15184/aqy.2022.107

Thirty years after the discovery of an Early Neolithic timber hall at Balbridie in Scotland was reported in Antiquity, new analysis of the site's archaeobotanical assemblage, featuring 20 000 cereal grains preserved when the building burnt down in th...

Turbidity Currents Can Dictate Organic Carbon Fluxes Across River‐Fed Fjords: An Example From Bute Inlet (BC, Canada) (2022)
Journal Article
Hage, S., Galy, V., Cartigny, M., Heerema, C., Heijnen, M., Acikalin, S., Clare, M., Giesbrecht, I., Gröcke, D., Hendry, A., Hilton, R., Hubbard, S., Hunt, J., Lintern, D., McGhee, C., Parsons, D., Pope, E., Stacey, C., Sumner, E., Tank, S., & Talling, P. (2022). Turbidity Currents Can Dictate Organic Carbon Fluxes Across River‐Fed Fjords: An Example From Bute Inlet (BC, Canada). Journal of Geophysical Research: Biogeosciences, 127(6), https://doi.org/10.1029/2022jg006824

The delivery and burial of terrestrial particulate organic carbon (OC) in marine sediments is important to quantify, because this OC is a food resource for benthic communities, and if buried it may lower the concentrations of atmospheric CO2 over geo...

Ecosystem effects of invasive crayfish increase with crayfish density (2022)
Journal Article
Galib, S., Sun, J., Gröcke, D., & Lucas, M. (2022). Ecosystem effects of invasive crayfish increase with crayfish density. Freshwater Biology, 67(6), 1005-1019. https://doi.org/10.1111/fwb.13897

1. The nature and extent of effects of increasing densities of non-native species on stream ecosystems remain poorly understood. Non-native crayfish are among the most invasive aquatic species and we hypothesised that, in temperate streams, the exten...

Summer sea-ice variability on the Antarctic margin during the last glacial period reconstructed from snow petrel (Pagodroma nivea) stomach-oil deposits (2022)
Journal Article
McClymont, E. L., Bentley, M. J., Hodgson, D. A., Spencer-Jones, C. L., Wardley, T., West, M. D., Croudace, I. W., Berg, S., Gröcke, D. R., Kuhn, G., Jamieson, S. S., Sime, L., & Phillips, R. A. (2022). Summer sea-ice variability on the Antarctic margin during the last glacial period reconstructed from snow petrel (Pagodroma nivea) stomach-oil deposits. Climate of the Past, 18(2), 381-403. https://doi.org/10.5194/cp-18-381-2022

Antarctic sea ice is a critical component of the climate system affecting a range of physical and biogeochemical feedbacks and supporting unique ecosystems. During the last glacial stage, Antarctic sea ice was more extensive than today, but uncertain...

A Comparison of Dietary Isotopes in Pulp Stones and Incremental Dentine from Early Neolithic Individuals of the Whitwell Long Cairn, England (2022)
Journal Article
Ostrum, B., Gröcke, D. R., & Montgomery, J. (2022). A Comparison of Dietary Isotopes in Pulp Stones and Incremental Dentine from Early Neolithic Individuals of the Whitwell Long Cairn, England. American Journal of Biological Anthropology, 177(4), 769-783. https://doi.org/10.1002/ajpa.24479

Objectives: This study investigates if palaeodietary information can be obtained from pulp stones through stable isotope analysis, presents a method for their extraction from tooth samples, and assesses their utility as a source of paleodietary infor...
