A 30-year (1971-2000) temperature and salinity climatology is presented for surface and near-bed regions of the NW European shelf seas, with a resolution of 1/6 longitude by 1/10 latitude. The data have been extracted from the International Council for the Exploration of the Sea (ICES) data centre and supplemented by additional records from the World Ocean Data Centre (WODC). From the original data, which are irregularly distributed in space and time, the mean monthly temperature and salinity are calculated, as well as the climatic mean annual cycle. The climatology presented here is an improvement upon all existing climatologies presented in the literature for the NW European shelf; covering a wider area on a finer scale and including the surface and near-bed distribution of both temperature and salinity. Comparison of our data with existing climatologies shows good agreement, with differences occurring where our climatology is an improvement. This climatology, which will prove to be valuable to many users in the marine community will be regularly updated and made available to all users via the ICES data centre.
This dataset provides an overview of the natural heritage sensitivity to wind farms. It identifies land with the greatest opportunity for wind farm development in natural heritage terms, and areas where natural heritage sensitivities indicate a medium or high level of constraint. The intermediate levels (Zone 3 high sensitivity - wild land search areas (hatched) and Zone 2 medium sensitivity (hatched)) indicate that the sensitivity does not apply to the entirety of that area, but only to a proportion. Zone 1 - lowest natural heritage sensitivity; Zone 2 - medium natural heritage sensitivity; Zone 3 - high natural heritage sensitivity. Further information can be found in the Strategic Locational Guidance for Onshore Wind Farms in respect of the Natural Heritage Policy Statement. This dataset was generated from the original vector data displayed in Map 5 available http://www.snh.gov.uk/planning-and-development/renewable-energy/onshore-wind/
The layers provide information on the intensity of mobile fishing associated with Oil and Gas pipelines and cables. Each layer was created by calculating the total number of fishing tracks in 1 km by 1 km squares along the length of each pipeline for four gear categories (see Rouse et al 2017). Fishing tracks were recreated for UK vessels greater than 15 m in length between 2007-2015 operating mobile demersal gear (otter trawls, pair trawls, beam trawlers and dredges) using vessel position data extracted from the Vessel Monitoring System. The layers can be used to aid the pipeline decommissioning process, including assessing the potential impacts and risks of different decommissioning options to commercial fisheries and informing the frequency of post-decommissioning monitoring according to level of fisheries interaction. The layers can also inform risk modelling for operational pipelines.
