Towards a first high resolution spatiotemporal reconstruction of Holocene Artic Sea Ice dynamics

Academic Profile

Previous Study and Work Experience – Also see CV.

For my undergraduate degree I studied Geology &Geophysics MSci at Imperial College London. I graduated with a First Class degree with honours, and completed an MSci Thesis on “The Provenance fingerprint of early Oligocene glaciation” looking at the provenance of glacially transported marine sediment from Nd isotope analysis of off-shore cores from a site proximal to the East Antarctic coast.

In 2012 I assisted on a research project at the National Oceanography Centre Southampton (NOCS)as part of a NERC Research Experience Placement (REP). I worked on a project examining ice-sheet extent during Pliocene intensification of northern hemisphere glaciation. Ice-rafted debris feldspar from deep-sea sediments from the North Atlantic Ocean underwent laser ablation lead isotope analysis mass spectrometry (LA-MC-ICP-MS) on a ThermoFinnigan Neptune. Stable isotope data (δ18O) were also created for benthic foraminiferal calcite using a Europa GEO 20–20 mass spectrometer equipped with carbonate preparation.

In the summer of 2011 I assisted on a research project at Imperial looking into the palaeoclimate of the PETM, and undertook various tasks ranging from fieldwork sampling in Spain to laboratory preparation and sample analysis.

Mapping Award – In my 1st undergraduate year, I received the Mapping award for my geological map produced on fieldwork in Urra, Spain

Mineralogical Association Prize – In 2011 I was awarded the Student Award for excellence in Mineralogy.

Current Research

My current DPhil research focuses on the Arctic environment, and specifically the interaction of climate and sea ice extent throughout the Holocene. I am using driftwood as a proxy for sea ice by tracking its age and path across the Arctic Ocean while caught up in sea-ice, enabling the concurrent ice sheet dynamics to be reconstructed. With sufficient sample collection from Arctic field sites, a pan-Arctic sea-ice reconstruction of high temporal and spatial resolution can be achieved.

The expected research results will be used to address important questions on past sea-ice dynamics and the coupling of sea-ice with surface currents and atmospheric circulation. It will also feed into further environmental research, such as hypotheses on the coupling between sea-ice and arctic biota and proxy-model comparisons of sea-ice and climate.
