This assessment has been developed by NAFC Marine Centre, on behalf of the Shetland Islands Marine Planning Partnership, with guidance from the Shetland Islands Marine Planning Partnership Advisory Group. The assessment provides a data baseline to support the development of a regional marine plan under the Marine Scotland Act (2010).

Please visit the Shetland Islands Regional Marine Planning Partnership website (under Data Provider) for more information, including the data originators for all the individual data sets used for the maps. It is not possible to list all the originators here. As the assessment is a snapshot in time, more up to date data may be available on MS Maps NMPi along with data originator details.

This layer has been developed to combine the outputs from “summer_max_tw_2003” and “summer_climate_change_sensitivity” SRTMN layers into a single layer that can be used to prioritise management where the relative importance of maximum temperature and temperature change are considered to be equal.

This was achieved by (1) dividing the predictions of ‘summer_max_tw_2003’ and ‘summer_climate_change_sensitivity’ into 5 equal categories between the minimum and maximum observed values (2) assigning these categories a value ranging from 1  (the hottest / most sensitive rivers) to 5 (the coolest / least sensitive rivers) (3) sum the rankings (-1) to produce an overall priority ranking (1:9) where rivers ranked as 1 are the highest priority for management (i.e. high river temperature and high climate sensitivity) and 9 the lowest.

These layers are the outputs of research which developed a national river temperature model for Scotland capable of predicting both daily maximum river temperature and sensitivity to climate change. This layer shows predictions of maximum daily river temperatures for the hottest year in the last 20 years (2003).
