PurposeResearch
Objectives1. To collect sediment and water samples from the vicinity of the Marchon phosphogypsum plant for the determination of natural-series radionuclides, using the ship's 'Searider' if conditions permit (ACB4).
2. Conduct two 25 h tetrapod stations, with additional sampling for 234Th/238U, in Liverpool Bay and off the Cumbrian coast (ACB6, COSEDS).
3. Lay three current meters and the tetrapod for a long-term deployment off the Cumbrian coast (ACB6, COSEDS).
4. Fish for dab in Liverpool Bay (contaminated site) and Cardigan Bay (control site). Blood samples will be taken for cytological and immunological purposes and live fish returned to Lowestoft for further study (AE).
5. Make observations on seabird distributions on the return leg (JNCC).

All the aims were successfully completed with the exception of aim 2, which could not be accomplished due to bad weather.
