Research title Palaeoclimate reconstructions from Arctic and Nordic shelf seas: development and application of multiple proxies. Summary of research On the 1st October 2008 I started a SAGES -funded Ph.D. studentship in the Department of Geographical and Earth Sciences at the University of Glasgow. I am interested in the use of Biomarkers (molecular fossils) as a tool to reconstruct past climate changes. Biomarker derived proxies such as the Alkenone unsaturation index, which allows the reconstruction of Sea Surface Temperatures (SSTs) help us to understand past climate change and its implications for current and future environmental change. During the course of my Ph.D. I will use different biomarkers to elucidate past climate change in the polar regions. The biomarkers will be extracted from ocean sediment cores and particulate organic matter (POM) samples from the water column. These samples have been retrieved from the Arctic by Dr. James Bendle on the "ICE CHASER" Arctic research expedition on the RRS James Clark Ross and from the Antarctic by myself on the RRS James Cook during the JC31 cruise (03.02.09 - 03.03.09). Additional samples from The Scottish Association of Marine Science (SAMS) will be analysed at a later stage during the Ph.D.
From the 1st of July 2007 to the 31st of July 2008 I worked as a research assistant at the Institute for Chemistry and Biology of the Marine Environment (ICBM) in the organic geochemistry group headed by Prof. Dr. Juergen Rullkoetter. I studied the hydrogen isotopic composition of higher plant wax components from plants from the west coast of Africa.
In June 2007 I received my diploma in Pure and Applied Chemistry at the University of Oldenburg, Germany. The diploma thesis “Analysis of Leaf Wax Components of Plants from the African Rain Forest with Regard to Their Molecular and Isotopic Composition and Their Use as Climate Indicators” was supervised by Prof. Dr. Juergen Rullkoetter.
