Dr Eleanor Maddison
I am the deputy laboratory manager in the Department of Geography. I have come to this role from a research background in reconstructing palaeoenvironmental and palaeoclimatic change. My expertise lies in micropalaeontology, geochemistry and sedimentology.

- Geochemistry (biomarkers, stable isotopes, water analysis)
- Microfossils (diatoms, foraminifera and chironomids)
- Microscopy (optical (stereo and compound) and scanning electron microscopes)
- Sedimentology (high-resolution logging, coring, in situ measurements)
- Fieldwork (UK, Arctic, Antarctic, USA)
Previous research projects:
Rapid Neoglacial transitions in the North Atlantic
Department of Geography, Durham University
The cause of mid-Holocene rapid cooling, about 4-6 ka, has puzzled researchers for some time. In order to ascertain the nature and origins of this event I used biomarkers and the remains of chironomids (non-biting midges) preserved in lake sediments to construct temperature records of this period of cooling.
Causes and consequences of global cooling in the mid-Miocene
Department of Earth and Environmental Sciences, Open University
An investigation of mid-Miocene cooling was made by conducting high-resolution logging and geochemical analysis of organic-rich marine sediments (Monterey Formation, California).
High-resolution analysis of Antarctic Quaternary diatom-rich laminated sediments
School of Earth, Ocean and Planetary Sciences, Cardiff University
An investigation into the seasonality of Late Quaternary Antarctic climate and sea ice conditions by examining laminated diatom-rich sediments from the Antarctic Peninsula (Palmer Deep) and East Antarctica (Mertz Ninnis Trough and Dumont D’Urville Trough). To do this a quantitative and qualitative high-resolution approach was employed to analyse diatom assemblages.
