Abstract

The data resource is a package of GIS shapefiles of modelled maximum and monthly (mean) densities of cetacean and seabird species presented in Natural Resources Wales’ Evidence Report No 646: Modelled Distributions and Abundance of Cetaceans and Seabirds in Wales and Surrounding Waters. Refer to report for further information.

Lineage

Modelled densities are derived from predictive GEE_GLM modelling of sightings and environmental variables. 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
