    Crutzen and Stoermer's (2000) naming of the 'Anthropocene' has provoked lively debate across the physical and social sciences, but, while the term is gradually gaining acceptance as the signifier of the current geological ...
  • The age of CO2 released from soils in contrasting ecosystems during the arctic winter 

    Hartley, IP; Garnett, Mark H.; Sommerkorn, M; Hopkins, DW; Wookey, PA (Elsevier, 2013)
    In arctic ecosystems, winter soil respiration can contribute substantially to annual CO2 release, yet the source of this C is not clear. We analysed the 14C content of C released from plant-free plots in mountain birch ...

    present ice-penetrating radar evidence for ancient (pre-glacial) and extensive erosion surfaces preserved beneath the upstream Institute and Möller ice streams, West Antarctica. Radar data reveal a smooth, laterally ...
  • Animal geographies II: methods 

    Buller, HJ (Sage, 2014)
    Animal geographies challenge not only the place and placing of the human and the animal but, critically, the methods we use to engage with both in relation. This second review considers the various methodological implications ...
  • Animal Geographies III: Ethics 

    Buller, HJ (SAGE Publications, 2015-04-19)
    There is no animal geography without ethics. The very coupling of the words gives rise to an ethical endeavor; an acceptance that animals have a geography, a making visible of animals within our human geography and ...
  • Antarctic ice sheet fertilises the Southern Ocean 

    Death, R.; Wadham, J.L.; Monteiro, F.; Le Brocq, A.M.; Tranter, M.; Ridgwell, A.; Dutkiewicz, S.; Raiswell, R. (European Geosciences Union (EGU) / Copernicus Publications, 2014-05-19)
    Southern Ocean (SO) marine primary productivity (PP) is strongly influenced by the availability of iron in surface waters, which is thought to exert a significant control upon atmospheric CO2 concentrations on glacial/interglacial ...
  • Antecedent conditions control carbon loss and downstream water quality from shallow, damaged peatlands.

  • Anticipating ubiquitous computing: Logics to forecast technological futures 

    Kinsley, Samuel (Elsevier, 2011-03)
