Comments | This long-term survey was initiated following the pollution of the bay by oil from the Amoco Cadiz in March 1978. The point is 0.3 miles south-east of the Pierre Noire beacon (NE of Morlaix Bay) at a depth of 17 metres from the chart datum on fine sand Abra alba-Hyalinoecia bilineata community. Sampling is done using a Smith McIntyre grab (10 unit samples of 0.1 m2 at each survey for a total area of 1 m2). Sieving is carried out on a 1 mm circular mesh. Samples are fixed to 10 % neutral formalin. Sampling frequencies have changed over time: 12/year from 1977 to 1985, 5/year from 1986 to 2007, 2/year since 2008. The Pierre Noire site has been a DCE support site since 2007. |
