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.
High resolution bathymetry data of Rockall and Helen's Reef collected 2011-2012 as part of the ROAME Offshore Fisheries and Conservation (OFFCON) project. Rockall, a tiny island just 19 metres high, sits on the very extremity of Scotland’s marine environment. Some 180 miles due west of St. Kilda, it is buffeted year round by the extreme winds and swell that the North Atlantic weather generates. As such, it is Scotland’s only truly offshore shallow water ecosystem. The islet of Rockall is actually the only part of vast plateau of submerged continent that remains above sea-level.
Measuring fishing effort is important for assessing the environmental sustainability of fish stocks and the socioeconomic efficiency of fishing activity. Fishing effort describes the amount of fishing gear used on a fishing ground over a given unit of time. Effort in this case is defined as number of creels hauled per day per 4 km2. This survey interviewed 198 creel vessel skippers from four regions, two on the west and two on the east coast of Scotland. This analysis has been produced from these SAMPLED vessels only. This IS NOT a census and IS NOT a map of all creeling effort in these waters or in the survey areas. This is an indication of potential fishing effort only and if creeling is not quantified in an area in this map, that DOES NOT mean creeling is not taking place. Equally quantified effort could be higher given some creeling vessels were not surveyed. Fishing effort outside of the surveyed area was not measured.

Nature Conservation Marine Protected Areas (MPAs) are designated under the Marine (Scotland) Act 2010 or the UK Marine and Coastal Access Act 2009. They have to be managed in a way that furthers the conservation objectives. The EU Habitats Directive requires Special Areas of Conservation (and Special Protection Areas) to be managed in a way that prevents deterioration of the qualifying features. The dataset contains boundaries and measures which are subject to Marine Conservation Orders (MCOs), the Inshore Fishing (Scotland) Act 1984 or the Common Fisheries Policy (CFP) The following URL provides a link to further information: http://www.gov.scot/Topics/marine/marine-environment/mpanetwork/MPAMGT/ Proposed measures will be available during consultations
This web feature service (WMS) contains those layers held on Marine Scotland's Marine Scotland Maps portal where Marine Scotland are the originator or custodian, but the data is limited to view only (eg licensed IPR from third party). Marine Scotland are a directorate of the Scottish Government.
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. The layers show the following: summer_max_tw_2015_16 – Predictions of maximum daily river temperatures for the hottest day between July 2015 and June 2016. summer_max_tw_2003 – Predictions of maximum daily river temperatures for the hottest year in the last 20 years (2003). summer_climate_change_sensitivity – Predictions of the change in river temperature that would result from a 1°C increase in air temperature. A fourth layer has been developed to combine the outputs from “summer_max_tw_2003” and “summer_climate_change_sensitivity” 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. Management_Priority_Layer – Management priority on a scale of 1:9 where 1 is the highest priority (i.e. high river temperature and high climate sensitivity) and 9 the lowest
Areas of search (AoS) have been created using a multi-criteria analysis generated constraint map that shows a range of suitability for offshore wind energy locations. This constraint map is the product of overlaying and weighting 20 relevant layers in a GIS. From the least constrained/most suitable areas some broad zones are drawn. These broad areas are then refined into the AoS by investigating the geographic proximity to important offshore activities and issues. The activities considered to refine the footprint of the broad areas were: fishing, shipping, marine nature protected areas and oil and gas installations. These AoS will serve as guidance to developers and planners as to the most suitable sites for further offshore wind developments in Scottish waters. These sites provide a zone where developments will enjoy minimised obstacles to consenting and licensing whilst still benefitting from adequate resource and appropriate environmental conditions. These sites are recommended by Marine Scotland as places where the consenting and licensing process will be streamlined, expedient and efficient as the likely interactions to be encountered by developers have already been considered. Marine Scotland does not oblige developers to occupy these locations but to consider them as the most appropriate sites.
The 21 Scottish marine regions and offshore marine regions are used for state of the sea assessments. These areas consolidate the existing statutory Scottish Marine Regions with non-statutory offshore marine regions. For the purposes of assessment, the offshore marine regions extend to the continental shelf limits (adjacent to Scotland)
