Origins, population structure, pathology and diet samples of diver and auk casualties of the Sea Empress oil spill

This dataset provides data on the examination of dead oiled seabirds from southwest Wales collected after the February 1996 Sea Empress oil spill in order to assess impact and damage done by the spill. Data was collected in order to determine origins, pathology and diet of casualties (seabirds affected by the Sea Empress oil spill).

Lineage

Measurements and other data for age/sex structure of samples, condition and possible origins mainly followed Hope Jones et al. (1982a). All birds were dissected unwashed and the head, left wing and a tarsus were detached and washed before measurement. All birds were dissected for sexing and to assess condition by scoring subcutaneous and visceral fat, from none (0) to heavy (3) (Hope Jones et al. 1982a). Contents of stomachs and oesophagi were examined for a different sub-sample to that used for pathology. Contents were examined with a binocular microscope at 10 x magnification and a scanning electron microscope where necessary. Food remains were compared with reference collections for identification. Non-food items were also recorded. Increased monitoring effort and impact assessment following the Sea Empress oil spill.
