Eutrophication has a greater influence on floodplain lake carbon cycling than dam installation across the middle Yangtze region (2022)
Journal Article
Zeng, L., McGowan, S., Swann, G. E., Leng, M. J., & Chen, X. (2022). Eutrophication has a greater influence on floodplain lake carbon cycling than dam installation across the middle Yangtze region. Journal of Hydrology, 614, Article 128510. https://doi.org/10.1016/j.jhydrol.2022.128510

Carbon cycling in shallow floodplain lakes is complex due to variability in delivery of flood-derived allochthonous organic matter (OM). Human activities have potential to significantly modify the carbon balance of lakes by damming which restricts ex...

In flux: Annual transport and deposition of suspended heavy metals and trace elements in the urbanised, tropical Red River Delta, Vietnam (2022)
Journal Article
Roberts, L. R., Do, N. T., Panizzo, V. N., Taylor, S., Watts, M., Hamilton, E., …Salgado, J. (2022). In flux: Annual transport and deposition of suspended heavy metals and trace elements in the urbanised, tropical Red River Delta, Vietnam. Water Research, 224, Article 119053. https://doi.org/10.1016/j.watres.2022.119053

Due to the depositional environment, river deltas are said to act as filters and sinks for pollutants. However, many deltas are also densely populated and rapidly urbanizing, creating new and increased sources of pollutants. These sources pose the ri...

Reconstruction of short-term storm surge-driven increases in shallow coastal lake salinity using ostracod shell chemistry (2022)
Journal Article
Roberts, L. R., Holmes, J. A., Horne, D. J., Leng, M. J., Sayer, C. D., Timms, R. G. O., …Kelly, A. (2022). Reconstruction of short-term storm surge-driven increases in shallow coastal lake salinity using ostracod shell chemistry. Natural Hazards, https://doi.org/10.1007/s11069-022-05459-9

Climate change threatens the current protection provided by coastal defences in low-lying mid-latitude regions and increases the risk to coastal lakes from future frequent and intense storms. Quantifying and understanding the impacts of past storm su...

Stalagmite evidence for Early Holocene multidecadal hydroclimate variability in Ethiopia (2022)
Journal Article
Asrat, A., Baker, A., Duan, W., Leng, M. J., Boomer, I., Akter, R., …Wang, L. (2022). Stalagmite evidence for Early Holocene multidecadal hydroclimate variability in Ethiopia. Quaternary Research, 110, 67-81. https://doi.org/10.1017/qua.2022.29

A multiproxy oxygen and carbon isotope (δ13C and δ18O), growth rate, and trace element stalagmite paleoenvironmental record is presented for the Early Holocene from Ethiopia. The annually laminated stalagmite grew from 10.6 to 10.4 ka and from 9.7 to... Read More about Stalagmite evidence for Early Holocene multidecadal hydroclimate variability in Ethiopia.

Nutrient availability in the North Pacific region not primarily driven by climate through the Quaternary (2022)
Journal Article
Snelling, A. M., Swann, G. E., Pashley, V., Lacey, J. H., Horstwood, M. S., & Leng, M. J. (2022). Nutrient availability in the North Pacific region not primarily driven by climate through the Quaternary. Palaeogeography, Palaeoclimatology, Palaeoecology, 601, Article 111109. https://doi.org/10.1016/j.palaeo.2022.111109

The subarctic North Pacific Ocean is a relatively understudied region in terms of palaeoclimate, limiting our understanding of how the region has both driven and responded to palaeoenvironmental events. Today, the subarctic North Pacific Ocean is mar... Read More about Nutrient availability in the North Pacific region not primarily driven by climate through the Quaternary.

Climate and human exploitation have regulated Atlantic salmon populations in the River Spey, Scotland, over the last 2000 years (2022)
Journal Article
Sear, D., Langdon, P., Leng, M., Edwards, M., Heaton, T., Langdon, C., & Leyland, J. (2022). Climate and human exploitation have regulated Atlantic salmon populations in the River Spey, Scotland, over the last 2000 years. Holocene, 32(8), 780-793. https://doi.org/10.1177/09596836221095983

Historical salmon catch records suggest that climatic variability, and more recently human exploitation, control patterns of abundance in Atlantic salmon populations. We present the first long-term (2000-year) reconstruction of Atlantic Salmon popula...

Micromilling vs hand drilling in stable isotope analyses of incremental carbonates: The potential for δ 13C contamination by embedding resin (2022)
Journal Article
Branscombe, T., Lee-Thorp, J., Schulting, R., & Leng, M. (2022). Micromilling vs hand drilling in stable isotope analyses of incremental carbonates: The potential for δ 13C contamination by embedding resin. Rapid Communications in Mass Spectrometry, 36(14), Article e9318. https://doi.org/10.1002/rcm.9318

Rationale: Embedding resins are commonly used to facilitate high-resolution sampling for stable isotope analysis but anomalous δ13C values have been observed in some cases. Here we compare the results of microsampling strategies for hand-drilled vers...

The importance of climate change, specifically drought, across the Maya region in the northern Neotropics, remains a topic of lively debate. Part of this discussion hinges on the coherency of response to climatic variability across different archives...
