Layer contains features with time values

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.

This layer depicts fishing intensity by all gears and uses the time-aware functionality to filter by year.

Marine Environmental Assessment Group data for organic contaminants, metals, biological effects and water chemistry collected for the Clean Seas Environment Monitoring Programme (CSEMP). Sediment and biota samples are analysed for organic contaminants (PAHs, PCBs and PBDEs) and trace metals. Biological effects are also measured in biota. Nutrients are measured in water samples. This layer shows the assessments from the UK Marine Environment Monitoring and Assessment National (MERMAN) database for reporting EROD in biota (female).

All data prior to 2011 is stored on the MSS Contaminants database, all data from 2012 is on LIMS. All data is submitted to the UK Merman database.
