Profile

Chris Clark obtained his BSc in physical geography from University of Wales, Aberystwyth in 1985. After this he worked as a milkman in order to earn money for a climbing expedition to the Himalayas. He returned to academia at Department of Geology and Geophysics, University of Edinburgh to work on a PhD on "Reconstruction of the behaviour of the Laurentide Ice Sheet using satellite imagery", which was completed in 1990, and the results published in Nature.

Chris became a lecturer at ��«Ӱҵ in 1990 and was awarded a personal chair in 2004, and holds the Sorby Chair of Geoscience since 2009. He currently lectures on Glacial Geomorphology and Glaciology, and on GIS.

Chris has supervised 19 PhD students, most (72%) of whom have continued in academia or industry research posts. He has acted as external examiner on PhDs in Britain, Sweden and France, as an associate editor for the Annals of Glaciology, and guest editor for Boreas. He has been external examiner for the Aberystwyth MSc in Glaciology, served on the Editorial Advisory Board of Earth Surface Processes and Landforms and as associate editor of the Journal of Maps.

Chris was a member of the Geography panel in the Research Excellence Framework (REF2014) and is a member for the current panel (REF2021) which aims to assess the quality of research in UK universities. He is a Fellow of Royal Geographical Society and a member of the International Glaciological Society, British Society of Geomorphology, Quaternary Research Association, and sometimes a member of the European Geophysical Union.

Research interests

My primary research interest is in glacial geomorphology, in particular the understanding of processes that lead to the formation of subglacial bedforms (drumlins, flutes etc), and the inverse solution that uses the pattern and distribution of such landforms to reconstruct the behaviour of ice sheets that existed during the last glaciation. I choose to use satellite imagery and elevation models for these purposes because they frequently permit new evidence to be detected and because they allow mapping at a scale compatible with the former ice sheet.

The ultimate aim of this work is to build up a detailed picture of the evolution of former ice sheets through the last glacial cycle and to use this information to improve both ice sheet and climate models.

BRITICE CHRONO

BRITICE-CHRONO is NERC consortium project that I led along with some 40+ researchers from eight universities, plus the British Geological Survey, British Antarctic Survey, NERC's radiocarbon facility and Scottish Universities Environmental Research Centre. The focus was on dating the retreat of the former British-Irish Ice Sheet to learn how rapidly ice retreated across the continental shelf and across the marine-to-terrestrial transition and then to use this knowledge to improve numerical ice sheet models used to predict changes in our existing ice sheets. Our team collected samples for dating from the Shetland to the Scilly Isles and from the seafloor surrounding Ireland and Britain, totalling 914 sites and yielding over 600 new ages on ice retreat. The British-Irish Ice Sheet is now the world’s most well constrained retreating ice sheet and is being used to develop ice sheet modelling. .

PALGLAC European Research Council

I am leading PALGLAC which is a European Research Council Advanced Grant. By focussing on the most numerous and spatially-extensive records of palaeo ice sheet activity - glacial landforms - this project aims to revolutionise understanding of past and future ice sheets. Our team will vastly increase the available record for tuning or validating ice sheet models, develop new tools for gathering landform and geochronological information, and establish procedures for integrating these into ice sheet modelling experiments.

Highlights of my research are:

Mega-scale glacial lineations
Ice sheet reconstructions
Palaeo ice streams
The British-Irish Ice Sheet – BRITICE-CHRONO
Drumlins

Teaching interests

Aligning with my main research interests and skills, my teaching is used to impart knowledge, technological expertise and curiosity about glacial environments. I am particularly interested in teaching about how we can use landforms from past glaciations to better understand how ice sheets and glaciers work, and from this, to inform us about the operation of the existing ice sheets in Antarctica and Greenland and the mountain glaciers of the world.

I teach students how to use geographic information systems (GIS) and satellite images to analyse and advance knowledge, and in the second year I teach some of the basics of glaciology and glaciation. By the third year, once our students have become proficient at reading published academic papers on the latest advances, we get stuck in on some interesting topics about the production of glacial landforms and how we can use these to decipher the extent and dynamics of ice sheets, such as the one that once covered Britain.

My main teaching activity is via lectures but also includes practical classes, reading groups where we interrogate scientific publications, and some class debates and discussions. For me some of the most satisfying 'teaching' is in supervising the undergraduate research projects (dissertations) and especially so when we discover something new.

Additional research projects

Mega-scale glacial lineations

groovepatch (small)

Discovery of a new type of large-scale (10 –100 km) landform signature (mega-scale glacial lineations) in Canada, led me to predict that these were the specific record of high velocity ice flow (surges or ice streams). They have since been found elsewhere, and in the last few years, remarkable submarine finds have been made on the continental shelf surrounding Antarctica. These are significant in that their context in relation to fast flow features in the existing ice sheet validate my predictions. It is thus now well established that mega-scale glacial lineations are a reliable record of ice stream flow. Current research explores the formation of these landforms and their wide-reaching implications on the controls of ice stream flow.

Discovered and named the phenomena and argued they were an indicator of ice streams in:

Ice sheet reconstructions

Ice sheet (small) Ice sheet UK (small)

Discovery that the beds of former ice sheets (ie whole of Canada) contain a complex and palimpsest record of former ice flow that be used to reconstruct the flow geometry and centres of mass of the ice sheets and how they evolved through time. This overturned the existing paradigm that viewed landforms as simply recording a single timeslice of activity or just retreat patterns.

I have made reconstructions for the ice sheets that covered whole of Canada, for Quebec, and for Britain and Ireland, and in Arctic and Far Eastern Russia .

It is now widely known that the centres of mass (ice divides) may migrate considerable (~1000 km) distances during growth and decay.

Palaeo ice streams

Ice stream (small) Ice stream structure (small)

Ice streams are fast flowing corridors embedded within slower flowing ice sheets. For Antarctica they are responsible for around 90% of ice mass lost from the system, even though they occupy only a small part of the perimeter (12 %). Their activity largely determines the stability and response of ice sheets to climate perturbations, and accordingly their functioning receives intensive research activity, and constitutes the greatest challenge to knowledge within glaciology.

I have contributed to this field, by making theoretical advances with regard to the geomorphological and geological imprint that ice streams should leave behind, and using EO to search for them in former ice sheets.

We are currently searching and investigating the tracks of ice streams that drained ice sheets during the last glaciation. Once found and investigated their geomorphological signature provides information on ice stream basal characteristics that can be used for parameterising or testing numerical models. We can make inferences about the basal controls on ice stream functioning, which are relevant to both contemporary and palaeo glaciology. The first International sympoisum on palaeo-ice streams was held in Denmark in 2001. A special issue of Boreas (32(1), edited by myself and collegues) reported some of the key papers.

BRITICE

Map and GIS database of glacial landforms and features related to the last British Ice Sheet

Published map now available

See "Buying a printed map"

Most glaciated countries have for some time had some form of 'glacial map' recording landforms and evidence resulting from the activity of former ice sheets.
The Glacial Map of Canada is an exemplary example (Prest, V.K., Grant, D.R. and Rampton, V.N. 1968: Glacial map of Canada. Geological Survey of Canada. Map 1253A.)

For the first time we now have a compilation map for the last British Ice Sheet.

The methods of production, scope and caveats, and the printed 'Glacial Map' at a scale of 1:625 000 are reported in:

Clark, C.D., Evans, D.J.A., Khatwa, A., Bradwell, T., Jordan, C.J., Marsh, S.H., Mitchell, W.A. and Bateman, M.D. (2004). Map and GIS database of landforms and features related to the last British Ice Sheet. Boreas, 33(4), 359-375.

Please note that it is important to consult this source as it fully describes the nature of the data, and caveats which are essential for appropriate interpretation of the features.

BRITICE map

The purpose of this web page is to support the above publication, and to permit academic users to have free access to the data used in compiling the 'Glacial Map'.

Example visualisations

BRITICE GIS

On-screen view of some of the GIS layers: trimlines (nunataks) in red, moraine ridges in brown and limit of glacigenic deposits in dashed black, overlaid on a DEM of topography for part of Wester Ross, Scotland. This illustrates how it is possible to interrogate any individual feature and receive information on the published source from where it derives and a brief explanatory comment.

BRITICE DEM

Oblique view of the York-Escrick moraines (in brown) from the GIS overlaid on a DEM rendition of topography.

BRITICE GIS2

Example of a small extract of the BRITICE GIS around the Solway Firth. Drumlins as black lines, meltwater channels in blue, moraines in brown, eskers in red, and erratic information in green.

What is included?

Emphasis is on information that constrains the last ice sheet. The following are included:

moraines eskers drumlins meltwater channels tunnel valleys trimlines limit of key glacigenic deposits glaciolacustrine deposits ice-dammed lakes erratic dispersal patterns shelf-edge fans and the Loch Lomond Readvance limit of the main ice cap.

Details about the data layers and file naming and geographic projection are stored in a accompanying 'readme.txt' file Consult the paper in Boreas for extra details.

To download all data layers and use an Arcview project file (*.apr) that allows a 'ready-made' and easy viewing of the database:
Download the zip file into a suitable folder name, say /britice. Unzip it in this folder such that all files remain in it. Start Arcview and 'open project' selecting the filename 'britice.apr'. The full database should appear with all categories labelled in the legend.

[Note that the data layer COAST is the property of Bartholomew's and cannot be used in publication or in commercial applications without their permission].

Important Links

The can provide further information, maps for purchase and digital data for elements within the GIS that came from their mapping programmes.
The BGS has web pages devoted to .

How was it compiled?

The compilation was produced by reviewing over 1,000 publications of the academic literature and British Geological Survey mapping. Relevant data were extracted from these and digitised and entered into a GIS. Note that the printed Glacial Map in Boreas is a generalisation (necessary for the reduced scale) of the data. For full-resolution data the GIS should be used.

Who has done the work?

Chris Clark (University of ��«Ӱҵ) and Dave Evans (University of Glasgow) led the work assisted by Wishart Mitchell (University of Durham) and Mark Bateman (University of ��«Ӱҵ). Important collaborators at the British Geological Survey (BGS) were Colm Jordan and Stuart Marsh, without whom the work would not have been possible. Anjana Khatwa and Tom Bradwell were employed to perform much of the data assessment and input. Neal Salomon and Lisa Collings are thanked for their work digitising some of the features, and Graham Allsopp is acknowledged for cartographic production of the map. Steve Wise is thanked for help regarding GIS implementation.

The BRITICE project was conceived and started in 1995, and rapidly grew in ambition from a simple A3 map to a fully-fledged GIS, bibliography and large map. Essential to the success of the project was the recognition of its value by Stuart Marsh and Colm Jordan and consequent timely support of funds from the BGS under their University Collaboration Scheme. The universities of ��«Ӱҵ and Glasgow are also acknowledged for their financial support, as is the Carnegie Trust for the Universities of Scotland, who greatly assisted in funding the production of the map.

Hey, you have missed an important feature. What about future editions?

The census date was 2002, and so anything published after this time is not included. It is inevitable that some of the information may be incorrect and require rejecting or revising. Additionally, we have likely missed some important aspects. If material is not included it might be because the information was not presented in map form, the mapping was of insufficient quality (with regard to geographic referencing), it did not fit our target layers, it conflicted with other, perhaps better mapped data on the same feature, or we simply did not find the relevant publication.

Our intention is that the GIS will be periodically updated to include newly published information, and for revisions where found necessary. We therefore appeal for extra information, criticisms or suggested amendments. Please direct these to Chris Clark (c.clark@sheffield.ac.uk) who will ensure that they are considered for the next update of the GIS. Please send a copy of the relevant publication, highlighting the features for consideration. It should be noted that data is restricted to published information (but including PhD theses) which provides a crude quality-control and more importantly ensures that all data can be traced back to more detailed descriptions and observations.

When future updates are made (BRITICE 2nd edition), the results will be posted on this web page for downloading.

How can I get hold of the BRITICE data?

All data is available at no cost, providing that the BRITICE project is acknowledged and cited in any publications or presentations. Commercial use is not permitted.

(open access)

The printed map is available in the Boreas publication listed above, at a scale of 1:625,000 (ca. 2m x 1 m in size). The paper also contains important details regarding the scope and accuracy of the data layers and caveats required to make appropriate interpretations.

The GIS contains over 20,000 features split into thematic layers (as above). Individual features are attributed such that they can be traced back to their published sources. Given that the published sources of information that underpin this work were derived by a piecemeal effort over 150 years then our main caveat is of data consistency and reliability.

Why have we done this?

It is hoped that this compilation will:

Stimulate greater scrutiny of published data Assist in palaeo-glaciological reconstructions of the ice sheet Facilitate use of field-evidence in numerical ice sheet modelling Help direct field-workers in their future investigations.

General contributions in Remote Sensing/Geographic Information Systems/Digital Elevation Models

Essentially other geospatial projects I have dabbled in (mostly in tropical coasts - coral reefs and mangroves), but also some archaeology, ecology, lineaments and other things), but I haven't relisted all my glacial ones here, see the other sections for these.
