See report for details. Shapefiles are filed in the following folder structure: Maximum, Months, (seabirds and cetaceans) and Months by Decade (cetaceans only). Seasons (for seabirds and cetaceans) and Seasons by Decade and Decades (for cetaceans only) can be constructed by combining the relevant monthly maps in GIS Maximum maps represent the maximum density per 2.5km2 cell from the monthly data layers Monthly maps are expressed as mean density per 2.5km2 cell. File names are named as: NRW (Natural Resources Wales)_IRS (Irish Sea)_Species_month (numeric)_projection (WGS84) Data in the shapefile consists of SP_ID (specific identifier), Species, LOW ( 5% quantile), FIT (density predicted from GEE-GLM model), and UPP (95% quantile) Quantiles are derived from simulations of the data (see report p32 for details). The sightings and effort maps illustrate underlying third-party data and cannot be made publicly available. Underlying data can be requested from individual providers
