A global compilation of diatom silica oxygen isotope records from lake sediment – trends and implications for climate reconstruction (2024)
Journal Article

Oxygen isotopes in biogenic silica (δ18OBSi) from lake sediments allow for quantitative reconstruction of past hydroclimate and proxy-model comparison in terrestrial environments. The signals of individual records have been attributed to different fa...

Isotope offsets in marine diatom δ18O over the last 200 ka (2008)
Journal Article

Previous work has suggested that a species effect may be present in diatom oxygen isotope ratios (δ18Odiatom). While predominantly attributed to be a size related species effect, currently the precise mechanism remains unknown. Here, two size fractio...

Environmental change in many tropical, alpine habitats remains poorly resolved due to an absence of proximate and sustained observations. In the Rwenzori Mountains of East Africa, glaciers have receded rapidly over the last century, and here we asses...

Diatom oxygen isotopes: evidence of a species effect in the sediment record (2007)
Journal Article

Diatom oxygen isotope measurements are commonly made on bulk mixed species assemblages due to the difficulty in purifying and separating individual taxa. As such, it is essential to understand processes in diatoms which may lead to isotope offsets bo... Read More about Diatom oxygen isotopes: evidence of a species effect in the sediment record.

A high-resolution late Holocene lake isotope record from Turkey and links to North Atlantic and monsoon climate (2006)

Establishing a time frame for the development of the modern halocline and stratified water column in the subarctic North Pacific has significant paleoclimatic implications. Here we present a d18O(diatom) record consisting of only two species that rep...
