  • De Angelis, Hernán; Jansson, Krister N.; Alm, Göran; Glasser, Neil F.; Hättestrand, Clas; Stroeven, Arjen P.; Kleman, Johan (2010-08)
    The last glacial maximum (LGM) outline and subsequent retreat pattern (21–7 kyr) of North American ice sheets are reasonably well established. However, the evolution of the ice sheets during their build-up phase towards ...
  • Finlayson, A. G.; Long, D.; Golledge, Nicholas R.; Merritt, J. W.; Wilson, C. K.; Mathers, H. E.; Everest, J. D.; Stoker, M. S.; Stevenson, A. G.; Hestvik, O. B.; Hubbard, Alun L.; Bradwell, Tom (2008-06-02)
    Strongly divided opinion has led to competing, apparently contradictory, views on the timing, extent, flow configuration and decay mechanism of the last British Ice Sheet. We review the existing literature and reconcile ...
  • Brewer, Paul A.; Macklin, Mark G.; Rowberry, Matt (2007)
    The number, form and origin of a stepped sequence of sub-horizontal surfaces in north Ceredigion, U.K., has been the subject of continuing controversy over nearly two centuries of investigation. Renewed impetus to re-examine ...
  • Antonarakis, A. S.; Brasington, James; Richards, Keith S. (2008-06-16)
    Light Detection and Ranging (LiDAR) provides high resolution horizontal and vertical spatial point cloud data, and is increasingly being used in a number of applications and disciplines, which have concentrated on the ...
  • Preece, S. J.; Pearce, N. J. G.; Westgate, J. A.; Froese, D. G.; Jensen, B. J. L.; Perkins, W. T. (2011-10-25)
    Old Crow tephra is the largest and most widespread Quaternary eruption presently known in eastern Beringia. Its major- and trace-element geochemistry, Fe-Ti oxides, and stratigraphic and paleoecological context indicate ...
  • Hoskins, Gareth (2012)
    Museums and heritage operations are increasingly employing experiential forms of interpretation, such as role adoption and first-person interpretation, in order to cultivate emotional bonds between visitors and the characters ...
  • Dixon, Deborah P.; Woodward, Keith; Jones III, John Paul (2008)
    On the other hand ... dialectics: a sometimes social, sometimes materialist, sometimes psychological, but always political ontology that has offered the foundational logic for historico-geographical methodologies, rumbles ...
  • Heley, Jesse (2011-10-27)
    This article explores the significance of researcher's positionality for the interpretation of local cultures of rurality. Drawing on personal experience of studying the apparent emergence of a new squirearchy in an English ...
  • Wallinga, Jakob; Bos, Adrie J. J.; Duller, Geoffrey Alastair Thomas (2008-02-01)
    We investigate both theoretically and experimentally the effect of stimulation mode on the separation of quartz optically stimulated luminescence (OSL) components. We find that, when assuming first-order kinetics with the ...
  • Kossler, Annette; Tarasov, Pavel; Schlolaut, Gordon; Nakagawa, Takeshi; Marshall, Michael; Brauer, Achim; Staff, Richard; Ramsey, Christopher Bronk; Bryant, Charlotte; Lamb, Henry; Demske, Dieter; Gotanda, Katsuya; Haraguchi, Tsuyoshi; Yokoyama, Yusuke; Yonenobu, Hitoshi; Tada, Ryuji; Lamb, Henry; Marshall, Michael (2011-06-15)
    High-resolution diatom, sediment and pollen analyses of two sections from the annually laminated SG06 core from Lake Suigetsu were used to study the onset and termination of the late-glacial climate reversal in central ...
  • Tsukamoto, S.; Duller, G. A. T.; Wintle, A. G.; Frechen, M. (2010-06)
    The luminescence characteristics of volcanic plagioclase from an andesitic tephra (Hakone-Tokyo pumice, Hk-TP) from Japan were studied in order to assess if optical dating of plagioclase could be applied to Quaternary ...
  • Roberts, H. M. (2006)
    This study discusses the values of equivalent dose (De) determined for samples taken for optical dating from a loess section at Loveland, Iowa, North America. A modified single-aliquot regenerative-dose (SAR) procedure was ...
  • Jacobs, Z.; Wintle, A. G.; Duller, G. A. T. (2003-05)
    An aeolian sand unit overlies the Middle Stone Age deposits at Blombos Cave on the southern Cape coast. These deposits contained culturally-important artefacts, including bone tools and pieces of engraved ochre, as well ...
  • Quincey, Duncan J.; Lucas, Richard M.; Richardson, S. D.; Glasser, Neil F.; Hambrey, Michael; Reynolds, John M. (2005)
    Remote sensing studies have shown that glaciers and their proximal environments exhibit unique temporal, spatial and spectral characteristics that can be analysed to better quantify glacial hazard potential. In this review, ...
  • Hubbard, Bryn; Tison, Jean-louis; Pattyn, Frank; Dierckx, Marie; Boereboom, Thierry; Samyn, Denis (2012-11-01)
    We have drilled thirteen boreholes within and around a through-cutting rift on Roi Baudouin Ice Shelf, East Antarctica. Logging by optical televiewer (OPTV), combined with core inspection, has resulted in the identification ...
  • Rowan, Ann V.; Roberts, H. M.; Jones, Merren A.; Duller, Geoff A. T.; Covey-Crump, Steve J.; Brocklehurst, Simon H. (2012-04)
    New Zealand is a key location for investigating the geomorphic response of fluvial systems over glacial–interglacial timescales, and as such provides a potentially rich archive of Quaternary climate change. Identification ...
  • Bøtter-Jensen, Lars; McKeever, Stephen W. S.; Wintle, Ann G. (Elsevier, 2003-10-24)
    Optically Stimulated Luminescence (OSL) has become the technique of choice for many areas of radiation dosimetry. The technique is finding widespread application in a variety of radiation dosimetry fields, including personal ...
  • Chandler, David M.; Hubbard, Bryn; Hubbard, Alun L.; Murray, Tavi; Rippin, David (2008-06-19)
    Internal ice strain rates have been measured along two boreholes drilled through Glacier de Tsanfleuron, Switzerland. Differences between these measurements and the output from a 3D numerical model of glacier motion have ...
  • Mitchell, Tyler; Lovell, Tom; Askins, Kye; Fuller, Duncan; Roberts, Margaret; Flaxman, Pete; Gordon, Linzi; Rothnie, Gail; Robinson, Guy; Hawkins, Harriet; Wheeldon, Rachel; Griffiths, Helen; Murphy, Claire; Cook, Ian; Sacks, Shelley; Swift, Di; Rawling, Eleanor; Evans, James; Allen, Daniel; Prescott, Heather; Wilson, Jacky; Williams, Alice; Feenay, Katie (2011-10-27)
    A new field of 'public geographies' is taking shape (Fuller 2008) in geography's mainstream journals. While much is 'traditional', with intellectuals disseminating academic research via non-academic outlets (Castree 2006; ...
  • Ricketts, D.; Telford, R.; Umer, M.; Lamb, H.; Kebede, S.; Leng, Melanie J. (2011-09-14)
    Millimetre-scale white aragonite laminations alternating with dark diatom-rich organic layers are present in the uppermost sediments of the crater lakes Hora and Babogaya, at Debre Zeit, Ethiopia. The sediment accumulation ...
