General Outline

I utilize geomorphic mapping, sedimentological analysis and geochronological techniques to reconstruct the timing and manner of glacier expansion and retreat. During the past seven years my work has mainly focused on building a better understanding of late Quaternary southern hemispheric glacial and climatic change. I have also been involved in utilizing sedimentological analysis to establish palaeo-glaciological dynamics of surge-type glaciers in Iceland.

To build glacier chronologies, I use in-situ produced terrestrial cosmogenic nuclide analysis (¹⁰Be, ²⁶Al, ³⁶Cl). In particular I have been developing an empirical dataset, tracking Patagonian Ice Sheet surface elevation and ice thickness changes as well as determining glacier extent during the last two glacial cycles (191-11.7 kyr) and the Holocene (11.7-present), in Chile & Argentina (42, 49, 53-55°S). This work provides key insights into the local palaeo-glaciology and regional palaeo-climatology of southern South America.

Ongoing research projects

• Chilean Fjords: using cosmogenic nuclides to establish ice sheet morphology changes through time & using marine cores to ascertain glacier dynamics through ice rafted debris deposits of the former marine-terminating Patagonian Ice Sheet between 53-55°S. Samples/cores were collected during Polarstern cruise PS97 in 2016. In collaboration with Dr. Lamy, AWI, Prof. Dr. Spiegel, University of Bremen & HWK-Institute of Advances Study, Germany.
• Chalten-HPS Patagonia: exposure dating of vertical dimensions of former Patagonian Ice Sheet surrounding El Chalten, Lago Viedma, Glaciers Chico & Viedma, Argentina/Chile (49°S, 72-73°W). In collaboration with Dr. Fabel (SUERC) and Prof. Glasser (Aberystwyth). 
• Northern Patagonia: exposure dating of vertical and horizontal glacier dimensions between Cholila - El Ricon, Argentina (41-42°S, 71°W), in collaboration with Dr. Ruiz, IANIGLA, Argentina. Recent successfull NERC-CIAF grant received (9166/0416). Extension of this project toward Esquel in collaboration with Dr. Smedley, Keele University, UK.
• Historical Patagonia: digitisation and analysis of historical weather data collected at remote Patagonian Estancias between the 1920s-1960s, in collaboration with Dr. Masiokas, IANGILA, Argentina.
• Mullajökull: Glacial geomorphology and sedimentology infront of surging glacier, Iceland. In collaboration with Dr. Benediktsson - (Lund), Dr. Schomacker (Copenhagen), Dr. Johnson (Gothenberg).
