|Cruise period||1976-01-02 — 1976-01-16|
|Port of departure||Grimsby, United Kingdom|
|Port of return||Grimsby, United Kingdom|
|Objectives||1. To continue the examination of the distribution of radiocaesium and
plutonium in the Irish Sea and its approaches.
2. To continue the examination of the distribution of radiocaesium in
coastal waters of the British Isles.
3. To collect seawater and suspended matter, over a tidal cycle period
at 6 stations in the vicinity of BNFL Windscale, at 3 depths in the water column.
4. To collect samples of seabed in the same vicinity for the examination
of the concentration of radioactivity of sediment in both the solid and liquid phases, at various depths from the surface layer.
5. To record the gamma count rate, in a selected energy range, from
seawater of the Irish Sea, with particular reference to a close
spaced grid off the Cumbrian coast.
6. To measure the concentrations of inorganic and total mercury in British Isles Coastal Waters.
