Cruise period1994-05-17 — 1994-06-03
StatusCompleted
Port of departureLowestoft, United Kingdom
Port of returnLowestoft, United Kingdom
Objectives1. To study the surface sediment and water concentrations of U, Th, Ra, Po and Pb radionuclides and nutrients in the immediate vicinity of the Marchon outfall and further offshore in the eastern Irish Sea. Part of this work is to be carried out in conjunction with a small charter vessel (AE0115A).
2. To commence a study to investigate the surface sediment and water concentrations of radionuclides from the Ribble estuary (AE0115A).
3. Collection of sediment cores from the Irish Sea and thus enable laboratory experiments to be carried out to evaluate the relative importance of historic and current discharges of radionuclides to the sea from Sellafield (AE0117A).
4. To collect and process surface water from the Irish Sea for the analysis Tc, Cs, Sb and transuranic radionuclides as part of the Post EARP survey (AE0114A, Nuclear Fission Safety Programme - CEC contract).
5. To collect plankton samples and hence study, in conjunction with aim 4, concentration processes of radionuclides in the primary food chain (AE0117A, Nuclear Fission Safety Programme).
6. Collection of live Plaice from Rye Bay and thus enable laboratory experiments to be carried out to evaluate radiation effects on reproduction (AE0116A).
7. To collect, on behalf of IAEA, a bulk fish sample for world wide distribution as a intercalibration reference sample.
All of the aims were successfully completed
