    • Drumlin relief 

      Spagnolo, Matteo; Clark, Chris D.; Hughes, Anna L.C. (Peer reviewed; Journal article, 2012)
      Drumlin relief is a key parameter for testing predictions of models of drumlin formation. Although this metric is commonly described in textbooks as being of the order of a fewtens ofmetres, our critical review of the ...

    • Evidence for the asynchronous retreat of large outlet glaciers in southeast Greenland at the end of the last glaciation 

      Dyke, Laurence M.; Hughes, Anna L.C.; Murray, Tavi; Hiemstra, John F.; Andresen, Camilla S.; Rodés, Ángel (Journal article, 2014-09-01)
      Recent rapid changes in the marine-terminating sectors of the Greenland Ice Sheet (GrIS) have prompted concerns about the future stability of the ice sheet. Long-term records of ice sheet behaviour provide valuable context ...

    • Growth and retreat of the last British–Irish Ice Sheet, 31 000 to 15 000 years ago: the BRITICE-CHRONO reconstruction 

      Clark, Chris D.; Ely, Jeremy C.; Hindmarsh, Richard C. A.; Bradley, Sarah; Ignéczi, Adam; Fabel, Derek; Ó Cofaigh, Colm; Chiverrell, Richard C.; Scourse, James; Benetti, Sara; Bradwell, Tom; Evans, David J. A.; Roberts, David H.; Burke, Matt; Callard, S. Louise; Medialdea, Alicia; Saher, Margot; Small, David; Smedley, Rachel K.; Gasson, Edward; Gregoire, Lauren; Gandy, Niall; Hughes, Anna L.C.; Ballantyne, Colin; Bateman, Mark D.; Bigg, Grant R.; Doole, Jenny; Dove, Dayton; Duller, Geoff A. T.; Jenkins, Geraint T. H.; Livingstone, Stephen L.; McCarron, Stephen; Moreton, Steve; Pollard, David; Praeg, Daniel; Sejrup, Hans Petter; Van Landeghem, Katrien J. J.; Wilson, Peter (Journal article; Peer reviewed, 2022)
      The BRITICE-CHRONO consortium of researchers undertook a dating programme to constrain the timing of advance, maximum extent and retreat of the British–Irish Ice Sheet between 31 000 and 15 000 years before present. The ...

    • Ice-flow patterns and precise timing of ice sheet retreat across a dissected fjord landscape in western Norway 

      Mangerud, Jan; Hughes, Anna L.C.; Sæle, Tone Herfindal; Svendsen, John-Inge (Peer reviewed; Journal article, 2019-06)
      We reconstruct patterns of ice flow and retreat of the southwestern Scandinavian Ice Sheet, from 2900 field observations of glacial striae and elevation measurements of 60 ice-marginal-deltas from a high-resolution LiDAR ...

    • The last Eurasian Ice Sheets - a chronological database and time-slice reconstruction 

      Hughes, Anna L.C.; Gyllencreutz, Richard; Lohne, Øystein Strand; Mangerud, Jan; Svendsen, John-Inge (Peer reviewed; Journal article, 2016-10-09)
      We present a new time-slice reconstruction of the Eurasian ice sheets (British–Irish, Svalbard–Barents–Kara Seas and Scandinavian) documenting the spatial evolution of these interconnected ice sheets every 1000 years from ...

    • A new global ice sheet reconstruction for the past 80 000 years 

      Gowan, Evan J.; Zhang, Xu; Khosravi, Sara; Rovere, Alessio; Stocchi, Paolo; Hughes, Anna L.C.; Gyllencreutz, Richard; Mangerud, Jan; Svendsen, John Inge; Lohmann, Gerrit (Journal article; Peer reviewed, 2021)
      The evolution of past global ice sheets is highly uncertain. One example is the missing ice problem during the Last Glacial Maximum (LGM, 26 000-19 000 years before present) – an apparent 8-28 m discrepancy between far-field ...

    • PaCTS 1.0: a crowdsourced reporting standard for paleoclimate data 

      Khider, Deborah; Emile-Geay, Julien; McKay, Nicholas P.; Gil, Yolanda; Garijo, Daniel; Ratnakar, Varun; Alonso-Garcia, Montserrat; Bertrand, Sebastien; Bothe, Oliver; Brewer, Peter; Bunn, Andrew G.; Chevalier, Manuel; Comas-Bru, Laia; Csank, Adam; Dassié, Emilie; DeLong, Kristine L.; Felis, Thomas; Francus, Pierre; Frappier, Amy; Gray, William R.; Goring, Simon; Jonkers, Lukas; Kahle, Michael; Kaufman, Darrell S.; Kehrwald, Natalie M.; Martrat, Belen; McGregor, Helen V; Richey, Julie; Schmittner, Andreas; Scroxton, Nick; Sutherland, Elaine K.; Thirumalai, Kaustubh; Allen, Kathryn J.; Arnaud, Fabien; Axford, Yarrow; Barrows, Timothy T.; Bazin, Lucie; Pilaar Birch, Suzanne E.; Bradley, Elizabeth; Bregy, Joshua; Capron, Emilie; Cartapanis, Olivier; Chiang, Hong-Wei; Cobb, Kim M.; Debret, Maxime; Dommain, René; Du, Jianghui; Dyez, Kelsey A.; Emerick, Suellyn; Erb, Michael P.; Falster, Georgina; Finsinger, Walter; Fortier, Daniel; Gauthier, Nicholas; George, Steve; Grimm, Eric C.; Hertzberg, Jennifer; Hibbert, Fiona D.; Hillman, Aubrey; Hobbs, William R; Huber, Matthew; Hughes, Anna L.C.; Jaccard, Samuel L.; Ruan, Jiaoyang; Kienast, Markus; Konecky, Bronwen; Le Roux, Gael; Lyubchich, Vyacheslav; Novello, Valdir F.; Olaka, Lydia; Partin, Judson; Pearce, Christof; Phipps, Steven J.; Pignol, Cecile; Piotrowska, Natalia; Poli, Maria-Serena; Prokopenko, Alexander; Schwank, Franciele; Stepanek, Christian; Swann, George E.A.; Telford, Richard; Thomas, Elizabeth R.; Thomas, Zoe; Truebe, Sarah; Von Gunten, Lucien; Waite, Amanda J.; Weitzel, Nils; Wilhelm, Bruno; Williams, John W.; Williams, Joseph J.; Winstrup, Mai; Zhao, Ning; Zhou, Yuxin (Journal article; Peer reviewed, 2019-09)
      The progress of science is tied to the standardization of measurements, instruments, and data. This is especially true in the Big Data age, where analyzing large data volumes critically hinges on the data being standardized. ...

    • Pervasive cold ice within a temperate glacier – implications for glacier thermal regimes, sediment transport and foreland geomorphology. 

      Reinardy, Benedict T.I.; Booth, Adam D; Hughes, Anna L.C.; Boston, Clare M.; Åkesson, Henning; Bakke, Jostein; Nesje, Atle; Giesen, Rianne H.; Pearce, Danni (Peer reviewed; Journal article, 2019-03-07)
      This study suggests that cold-ice processes may be more widespread than previously assumed, even within temperate glacial systems. We present the first systematic mapping of cold ice at the snout of the temperate glacier ...
