Prof Mike Walker
Professor Emeritus of Quaternary Science
Prof Mike Walker B.A. (Oxford), M.Sc. (Calgary), PhD. (Edinburgh), FSA
Mike’s main research interests are in the Late Quaternary, and especially in the Lateglacial (15-10 k cal yrs BP), a period on which he has been working for more than 30 years.
He is particularly interested in short-term climate change, its impact on landscape, and its manifestation in proxy records. His research has also been concerned with aspects of stratigraphy and chronology, especially radiocarbon dating, during the Last Glacial-Interglacial Transition.
He has published more than 140 scientific papers and other contributions, and is co-author of two Quaternary textbooks: Reconstructing Quaternary Environments (with John Lowe), (1st edition, Longman, 1984; 2nd edition, Addison-Wesley-Longman, 1997), and Late Quaternary Environmental Change: Physical and Human Perspectives (with Martin Bell), (1st edition, Longman, 1992; 2nd edition, Pearson International, 2005). His most recent book is Quaternary Dating Methods, (John Wiley, Chichester & New York, 2005).
Mike has chaired the Natural Environment Research Council (NERC) Radiocarbon Facilities Steering Committee (1995-1999), the NERC Accelerator Mass Spectrometry Strategy Group (2000-2004), and the NERC Cosmogenic Isotope Analysis Facility Steering Committee (2005-2007).
He was a member of the NERC Earth Sciences Peer Review Committee (1999-2002), of the Services Review Group (2001), and of the EFCHED (Environmental Factors in the Chronology of Human Evolution and Dispersal) Steering Committee (2001-2006).
He has been President of the Quaternary Research Association of Great Britain (1999-2002), and Editor of Journal of Quaternary Science(1995-1999). He continues to serve on the Editorial Board of Journal of Quaternary Science (John Wiley) and is a former member of the Editorial Board of Quaternary Science Reviews (Elsevier: 2000-2005).
He was the European co-ordinator for the IGCP-253 Termination of the Pleistocene ‘North Atlantic Seaboard Program’ (1990-1994), and co-founder, in 1995 of INTIMATE (Integration of Ice core, Marine and Terrestrial Records), now a core program of the INQUA (International Union for Quaternary Research) Palaeoclimate Commission.
He was Secretary of the Palaeoclimate Commission from 1999-2003, and is currently a Member of the INQUACommission on Stratigraphy and Chronology, and of the Subcommission on Quaternary Stratigraphy(SQS) of theInternational Commission on Stratigraphy(ICS).
He has recently Chaired a Joint Working Group of INTIMATE and the SQS to define the base of the Holocene.
He is also a member of the Working Group of the SQS on the Anthropocene base of the Holocene, and is currently chairing a new INTIMATE/SQS Working Group to consider a formal subdivision of the Holocene.
Mike is a Fellow of the Society of Antiquaries and an Honorary Professor in the Institute of Geography and Earth Sciences, University of Aberystwyth.
