Common scoter Melanitta nigra monitoring in Carmarthen Bay following the Sea Empress oil spill.

Following the Sea Empress oil spill, a monitoring programme was immediately established by the Countryside Council for Wales to record numbers and distribution of Common Scoters in Carmarthen Bay. Scoters generally prefer feeding in waters less than 10 m deep and previous aerial surveys in Carmarthen Bay have shown that most birds feed inshore of the 10 m depth contour which extends some 6-10 km offshore. The purpose of this data capture was to assess the impact of the Sea Empress oil spill on Common Scoter numbers and distribution in Camarthen Bay. There is high confidence in this dataset as surveys undertaken by experienced staff members. However no spatial reference were provided with data for statistical analysis. It is assumed for the purpose of the metadata that samples were collected using British National Grid.

A total of 30 land-based counts were conducted at two-week intervals between 23 February 1996 and 1 April 1997. For monitoring purposes, the bay was divided into 13 sectors and each counted from vantage points collectively covering all coastal areas of the bay. Six aerial surveys of Carmarthen Bay were conducted by RSPB using a high-wing Cessna 185 aircraft flying at 120 m and 90 knots. For compatibility with previous surveys in 1976, aerial surveys followed a circular route of the bay with transect lines some 3-5 km apart. As birds were only visible at distances up to 500 m either side of the aircraft, this survey route provided an index of scoter numbers and distribution rather than a total count. A sustained program of monitoring scoters in Carmarthen bay has been in place since 1997.
