Data for the 8-parent MAGIC map, including the genetic map, genetic data for the founding lines and founder population, and the imputed underlying genotypes.

This dataset contains counts of breeding seabirds derived from surveys by professional and volunteer ornithologists from within sub-sites defined using 6-figure OS grid references. Counts were derived from a complete census of seabird colonies in Britain and Ireland as part of the Seabird 2000 census. The Seabird 2000 dataset contains data from a full census of all of the breeding seabirds in Britain and Ireland. The data was gathered between the years 1999 and 2003 from both coastal and inland colonies. The main objectives of the survey were: to obtain distribution and population information for all 25 species of seabird that regularly breed in the UK and Ireland; to get baseline figures for those species that had been surveyed poorly up to now. The dataset contains points representing counts of nesting seabirds in sub-sites - stretches of coastline showing start and end point of subsites about 1km in length. Also points representing counts of nesting seabirds in sub-sites away from the coast which represent polygons. This dataset is visualised as a mapping layer on Natural England's MAGIC site http://magic.defra.gov.uk/MagicMap.aspx.

Seabird concentrations are especially vulnerable to oil pollution, and may become contaminated by oil wherever concentrations occur at sea, sometimes at considerable distance from the coast. This data highlights the most vulnerable aggregations for each month of the year in offshore waters based on their abundance in each statistical rectangle and their vulnerability to the effects of oil pollution. The data was compiled in 1995. Points represent centre of 1/4 ICES Rectangle (15' lat x 30' long).

Seabird observations were captured manually or electronically from navigational equipment (e.g. GPS). Calculated values were derived from sea surveys collected for the European Seabirds at Sea Database.

The monthly data layers are visualised on Natural England's MAGIC site http://magic.defra.gov.uk/MagicMap.aspx.

Stężenia ptaków morskich są szczególnie narażone na zanieczyszczenie ropą naftową i mogą zostać zanieczyszczone ropą naftową wszędzie tam, gdzie występują stężenia na morzu, czasami w znacznej odległości od wybrzeża. Dane te podkreślają najbardziej wrażliwe agregacje dla każdego miesiąca roku na wodach morskich w oparciu o ich obfitość w każdym prostokątie statystycznym i ich podatność na skutki zanieczyszczenia ropą naftową. Dane zostały zebrane w 1995 roku. Punkty reprezentują środek prostokąta ICES 1/4 (15' lat x 30' long).

Obserwacje ptaków morskich były rejestrowane ręcznie lub elektronicznie z urządzeń nawigacyjnych (np. GPS). Obliczone wartości pochodzą z badań morskich zebranych na potrzeby europejskiej bazy danych ptaków morskich.

Miesięczne warstwy danych są wizualizowane na stronie MAGIC Natural England http://magic.defra.gov.uk/MagicMap.aspx.
