Multi-level ocean projections

In UKCP09 the multi-level ocean projections provide projected changes to the waters of the north-west European Continental shelf (the seas around the UK).

In detail

UKCP09 reports on projected changes in temperature, salinity, and currents of the water-column in the seas around the British Isles. The projections are taken from two model experiments of the Proudman Oceanographic Laboratory Coastal Ocean Modelling System (POLCOMS) for the time periods of 1961-1990 and 2070-2099.

Projections are available at a resolution of 12 km but no information on uncertainty is given with these projections as these experiments have so far been based on a single member of the Met Office RCM ensemble.

  • The multi-level ocean projections are summarised in  of the UKCP09 Briefing Report with more details in  of the UKCP09 Marine & Coastal Projections report.
  • Some case studies have been that used dummy outputs to examine how the UKCP09 marine & coastal projections might be used. They should not be interpreted as a best practice method for using UKCP09, but as one way of using the outputs.
