The formation of Mega Scale Glacial Lineations: insights into the mechanisms of ice stream flow
Related funds: NERC new investigator, NERC iSTAR
MSGL are extremely elongated ridges that maintain a parallel conformity over length of 10s of km. MSGL are the morphological expression of ice stream flow and are a signature of physical conditions at the ice-bed interface. Thus, the correct understanding of their formation is undoubtedly a key piece of the puzzle for solving fundamental questions regarding the dynamic behaviour of ice streams. In this project I am creating the largest (10s of thousands) database of mapped MSGL, onshore and offshore, and analyzing their metrics variability and spatial distribution.
Drumlins: do we really know what they are?
Related funds: NERC standard grant, NERC GEF
Drumlins are likely the most studied landforms in glacial geomorphology (>1400 papers), and yet it is not clear how they are formed. Mega Scale Glacial Lineations have been “discovered” only a few decades ago but they have quickly become one of the best indicators of particularly fast flowing ice (ice streams). As part of the NERC project “testing the instability theory of subglacial bedform production”, I have discovered that many ideas of drumlin formation are based on assumptions of drumlin morphometry that are potentially wrong because based on out-of-dated techniques applied over a very small sample of landforms. With the increasing availability of GIS tools and DTM data it is now possible to map and analyze thousands of these landforms and re-write drumlins’ characteristics.
Pleistocene Alpine glaciers as a proxy to palaeo-climate
Related funds: Leverhulme Trust, EU FP7, Carnegie Trust and NERC-SUERC
There are three distinct projects on this topic each focusing on a separate region, plus an overall arching project that looks at the Younger Dryas climate throughout Europe. The three distinct projects focus on: (i) the South-Western Alps, a region of high interest within the Alps for palaeo-glaciological and climatological studies, given its exceptional proximity to the Mediterranean Sea; (ii) the Balkans, where the glaciation record is crucial to understand the latitudinal distribution of ice masses during the Quaternary and provide key insights on the southern European palaeo-climate; (iii) the Faroe Islands, ideally placed to constraint the location of the polar front at the Younger Dryas.
