UKCP09: Marine data for UK waters from past and future multi-level ocean model simulations
Abstract
The UK climate projections 2009 (UKCP09) marine and coastal multi-level ocean projections provide detailed information on the potential future implications of climate change on the marine environment in UK waters.
Marine parameters are provided for projections of changes in water temperature, salinity, currents and stability of the water column over a 12km marine grid, for the 30 year time period 2070-2099 (and the baseline period 1961-1990) for the medium emissions scenario (IPCC SRES: A1B).
Note: The multi-level ocean projections are based on a single model simulation. In contrast to some other components of UKCP09 these are not probabilistic projections, meaning they do not quantify the range of future changes associated with modelling uncertainties or natural climate variability.
More information about the variables and methodology (including assumptions and caveats) are given in Chapter 6 of the Marine & coastal projections report (see linked documentation).

Process overview
| Title | UKCP09 data computation with POLCOMS model |
| Abstract | These UKCP09 data were generated using outputs from a Met-Office Hadley Centre (MOHC) regional climate model simulation to drive the Atlantic Margin application shelf sea model of the Proudman Oceanographic Laboratory Coastal Ocean Modelling System (POLCOMS) (now the National Oceanography Centre Liverpool; NOCL). The POLCOMS shelf sea model is well established having been used operationally by the UK Met Office since 2002 and used in many scientific projects by NOCL (formerly POL) and the UK research community. It has been validated with observations from marine weather stations. See the marine and coastal projections report for full details. |
