Holocene carbon dynamics at the forest – steppe ecotone of southern Siberia (2016)
Journal Article
Mackay, A. W., Seddon, A., Leng, M. J., Heumann, G., Morley, D., Piotrowska, N., …Swann, G. E. (2017). Holocene carbon dynamics at the forest – steppe ecotone of southern Siberia. Global Change Biology, 23(5), https://doi.org/10.1111/gcb.13583

The forest–steppe ecotone in southern Siberia is highly sensitive to climate change; global warming is expected to push the ecotone northwards, at the same time resulting in degradation of the underlying permafrost. To gain a deeper understanding of... Read More about Holocene carbon dynamics at the forest – steppe ecotone of southern Siberia.

Astronomical constraints on the duration of the Early Jurassic Pliensbachian Stage and global climatic fluctuations. Earth and Planetary Science Letters, 455, https://doi.org/10.1016/j.epsl.2016.08.038

The Early Jurassic was marked by multiple periods of major global climatic and palaeoceanographic change, biotic turnover and perturbed global geochemical cycles, commonly linked to large igneous province volcanism. This epoch was also characterised... Read More about Astronomical constraints on the duration of the Early Jurassic Pliensbachian Stage and global climatic fluctuations.

Large igneous provinces (LIPs) are proposed to have caused a number of episodes of abrupt environmental change by increasing atmospheric CO2 levels, which were subsequently alleviated by drawdown of CO2 via enhanced continental weathering and burial...

Sedimentary sequences in ancient or long-lived lakes can reach several thousands of meters in thickness and often provide an unrivalled perspective of the lake's regional climatic, environmental, and biological history. Over the last few years, deep... Read More about Scientific drilling projects in ancient lakes: integrating geological and biological histories.

Low-latitude Holocene hydroclimate derived from lake sediment flux and geochemistry (2016)
Journal Article

This study investigates hydrological responses to climatic shifts using sediment flux data derived from two dated palaeolake records in south-east Arabia. Flux values are generally low during the early Holocene humid period (EHHP) (∼9.0–6.4k cal a BP...

A tale of two lakes: a multi-proxy comparison of Lateglacial and Holocene environmental change in Cappadocia, Turkey (2016)
Journal Article
Roberts, N., Allcock, S. L., Arnaud, F., Dean, J. R., Eastwood, W. J., Jones, M. D., …Yiğitbaşıoğlu, H. (2016). A tale of two lakes: a multi-proxy comparison of Lateglacial and Holocene environmental change in Cappadocia, Turkey. Journal of Quaternary Science, 31(4), https://doi.org/10.1002/jqs.2852

Individual palaeoenvironmental records represent a combination of regional-scale (e.g. climatic) and site-specific local factors. Here we compare multiple climate proxies from two nearby maar lake records, assuming that common signals are due to regi...

Carbon incorporated into diatom frustule walls is protected from degradation enabling analysis for carbon isotope composition (δ13Cdiatom). This presents potential for tracing carbon cycles via a single photosynthetic host with well-constrained ecoph...
