© 2013 Elsevier B.V. All rights reserved. Diatom silica is a form of biogenic opal (SiO2·nH2O) that contains oxygen isotopes that can be used in lacustrine and marine paleoenvironmental studies. Here we describe the various analytical considerations... Read More about DIATOM METHODS | δ18O Records.

Palaeo-seasonality of the last two millennia reconstructed from the oxygen isotope composition of carbonates and diatom silica from Nar Gölü, central Turkey (2013)
Journal Article
Dean, J. R., Jones, M. D., Leng, M. J., Sloane, H. J., Neil Roberts, C. N., Woodbridge, J., Swann, G. E., Metcalfe, S. E., Eastwood, W. J., & Yiǧitbaşioǧlu, H. (2013). Palaeo-seasonality of the last two millennia reconstructed from the oxygen isotope composition of carbonates and diatom silica from Nar Gölü, central Turkey. Quaternary Science Reviews, 66, 35-44. https://doi.org/10.1016/j.quascirev.2012.07.014

Carbonates and diatoms are rarely deposited together in lake sediments in sufficient quantities for the oxygen isotope composition (δ18O) to be investigated simultaneously from both hosts. Here, d18Ocarbonate are compared to δ18Odiatom data from the...

Hydrological instability during the Last Interglacial in central Asia: a new diatom oxygen isotope record from Lake Baikal (2013)
Journal Article
Mackay, A. W., Swann, G. E., Fagel, N., Fietz, S., Leng, M. J., Morley, D., Rioual, P., & Tarasov, P. (2013). Hydrological instability during the Last Interglacial in central Asia: a new diatom oxygen isotope record from Lake Baikal. Quaternary Science Reviews, 66, 45-54. https://doi.org/10.1016/j.quascirev.2012.09.025

Last Interglacial variability is commonly used as an analogue for variability in a future, warmer world. Pervasive cycles are increasingly apparent in Last Interglacial archives, although studies in continental regions are under-represented. Here we...

Glacial discharge along the west Antarctic Peninsula during the Holocene (2013)
Journal Article
Pike, J., Swann, G. E., Leng, M. J., & Snelling, A. M. (2013). Glacial discharge along the west Antarctic Peninsula during the Holocene. Nature Geoscience, 6, https://doi.org/10.1038/ngeo1703

The causes for rising temperatures along the Antarctic Peninsula during the late Holocene have been debated, particularly in light of instrumental records of warming over the past decades. Suggested mechanisms range from upwelling of warm deep waters... Read More about Glacial discharge along the west Antarctic Peninsula during the Holocene.

Seasonally resolved diatom δ18O records from the west Antarctic Peninsula over the last deglaciation (2013)
Journal Article
Swann, G. E., Pike, J., Snelling, A. M., Leng, M. J., & Williams, M. C. (2013). Seasonally resolved diatom δ18O records from the west Antarctic Peninsula over the last deglaciation. Earth and Planetary Science Letters, 364, https://doi.org/10.1016/j.epsl.2012.12.016

Understanding the response of the Antarctic ice sheets during the rapid climatic change that accompanied the last deglaciation has implications for establishing the susceptibility of these regions to future 21st Century warming. A unique diatom δ18O... Read More about Seasonally resolved diatom δ18O records from the west Antarctic Peninsula over the last deglaciation.
