UKCP09 is the name given to the UK Climate Projections. UKCP09 provides future climate projections for land and marine regions as well as observed (past) climate data for the UK.This layer is part of the Sea Surface and Seabed Temperature Change sub-set of the UKCP09 marine and coastal projections up to 2090s using a medium emission scenario and, where appropriate, medium probability. It displays the change in sea surface salinity for winter up to 2085 under a medium emissions scenario.
Summarising the anticipated changes around Scotland based on central estimate projections for 2080-90 using the medium emission scenario, surface salinity is projected to decrease everywhere, and in fact around the entire north east Atlantic, by about 0.2 salinity units. This decrease is mainly due to wide scale changes in the ocean rather than the local effect of rivers. There is very little regional or seasonal variability.
