Port of departureLowestoft, United Kingdom
Port of returnLowestoft, United Kingdom
PurposeResearch
Objectives1. To collect and process surface water from UK coastal waters for the analysis of Tc, Cs, Sb and transuranic radionuclides as part of the Enhanced Actinide Removal Plant survey (AE0114A, Nuclear Fission Safety Programme).
2. To compare the spatial distribution of the present oxidation state of transuranium elements discharges into the Irish Sea from Sellafield with discharges into the Channel from Cap de La Hague (AE0114A).
3. To collect a large volume sample of surface Atlantic water for low level radionuclide incomparison purposes (AE0114A).
4. 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 done in conjunction with a small charter vessel (AE0115A).
5. To recover tetrapod and quadrapod from west of Barrow and current meters from the North Channel (AE0114A, AE0128A, U Cambridge).
6. To conduct further studies to determine changes in the actinide colloidal distributions in both surface and bottom waters using a variety of innovative techniques at a number of key sites (AE0114A, U C Dublin, U Norway).
7. To collect live Dab from a contaminated region of Liverpool Bay and a relatively clean region of Cardigan Bay for an ongoing study of the effects of pollutants on Dab chromosomes (AE0116A).
