ObjectivesThe objectives of this cruise were as follows:
1) To carry out vibrocoring at various locations in Swansea Bay to determine the thinkcness and structure of potentially mobile sediment and in the radioactive tracer zone to determine the depths of burial of tracer (the latter in conjunction with AERE Harwell)
2) In conjunction with AERE Harwell to carry out spectral degradation measurements to determine the depths of burial of the tracer.
3) To determine near-bed suspended sediment concentrations and particle size distributions at locations offshore between Port Talbot and Porthcawl.
4) To make near-bed velocity profile measurements at those locations in (3) to enable sediment flux rates and bed shear stresses to be calculated.
