Dosbarthiad ac amlder a fodelwyd ar gyfer Morfilod ac Adar Morol Cymru a'r Dyfroedd Cyfagos
Mae hon yn set ddata o ddwyseddau mwyaf a misol (cymedrig) a fodelwyd ar gyfer rhywogaethau o forfilod ac adar môr penodol ym Môr Iwerddon a’r Môr Celtaidd o amgylch Cymru. Mae dwyseddau a fodelwyd yn deillio o fodelu rhagfynegol o achosion o weld y creaduriaid a newidynnau amgylcheddol. Mae'r mapiau mwyaf yn cynrychioli'r dwysedd mwyaf fesul cell 2.5km2 o'r set ddata gyfan. Mynegir mapiau misol (adar môr a morfilod) a degawdol (morfilod yn unig) fel dwysedd cymedrig fesul cell 2.5km2.
Gellir lawrlwytho'r data mwyaf a fodelwyd gan ddefnyddio Map Data Cymru. Ar gyfer data misol (ar gyfer adar môr a morfilod) a degawdol (ar gyfer morfilod yn unig) dilynwch y ddolen hon.
Gellir adeiladu tymhorau (ar gyfer adar môr a morfilod) a Tymhorau yn ôl Degawd a Degawdau (ar gyfer morfilod yn unig) drwy gyfuno'r mapiau misol perthnasol yn GIS

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.
