    Watson, AJ; Lenton, TM; Mills, BJW (Royal Society, 2017-08-07)
    The major biogeochemical cycles which keep the present-day Earth habitable are linked by a network of feedbacks which has led to a broadly stable chemical composition of the oceans and atmosphere over hundreds of millions ...

    A large volume of the East Antarctic Ice Sheet drains through the Totten Glacier (TG) and is thought to be a potential source of substantial global sea level rise over the coming centuries. We show the surface velocity and ...
  • Ocean ventilation and deoxygenation in a warming world: introduction and overview 

    Shepherd, JG; Brewer, PG; Oschlies, A; Watson, AJ (Royal Society, 2017-08-07)
    Changes of ocean ventilation rates and deoxygenation are two of the less obvious but important indirect impacts expected as a result of climate change on the oceans. They are expected to occur because of (i) the effects ...
  • The OceanFlux Greenhouse Gases methodology for deriving a sea surface climatology of CO2 fugacity in support of air–sea gas flux studies 

    Goddijn-Murphy, LM; Woolf, DK; Land, Peter E.; Shutler, Jamie D.; Donlon, Craig J. (Copernicus Publications, 2015-07-08)
    Climatologies, or long-term averages, of essential climate variables are useful for evaluating models and providing a baseline for studying anomalies. The Surface Ocean CO2 Atlas (SOCAT) has made millions of global underway ...
  • Oceans on the edge of anoxia 

    Watson, AJ (American Association for the Advancement of Science, 2016-12-23)
    Environmental crises can tip the ocean into O2 depletion
  • On the calculation of air-sea fluxes of CO2 in the presence of temperature and salinity gradients 

    Woolf, DK; Land, Peter E.; Shutler, Jamie D.; Goddijn-Murphy, LM; Donlon, Craig J. (Wiley-Blackwell, 2016)
    The presence of vertical temperature and salinity gradients in the upper ocean and the occurrence of variations in temperature and salinity on time scales from hours to many years complicate the calculation of the flux of ...
  • On the milieu of security: situating the emergence of new spaces of public action 

    Barnett, Clive (SAGE Publications, 2015-11)
    Critical analysis of security presents processes of securitization as sinister threats to public values such as accountability, inclusion and transparency. By questioning some of the theoretical premises of this view of ...
  • On the politics of lapdogs, Jim’s dog, and crittercams 

    Davies, Gail; Loftus, A (Pion, 2010)
    There is no abstract for this paper.
  • On the potential of surfers to monitor environmental indicators in the coastal zone 

    Brewin, RJW; de Mora, L; Jackson, T; Brewin, TG; Shutler, Jamie D. (Public Library of Science, 2015-07-08)
    The social and economic benefits of the coastal zone make it one of the most treasured environments on our planet. Yet it is vulnerable to increasing anthropogenic pressure and climate change. Coastal management aims to ...
  • On the recent elevation changes at the Flade Isblink Ice Cap, northern Greenland
