Cruise summary report
|Ship name (ship code)||RV Clione (74CN)|
|Cruise period||1979-02-27 — 1979-03-15|
|Port of departure||Lowestoft, United Kingdom|
|Port of return||Lowestoft, United Kingdom|
1. To service the JONSIS current meter stations.
2. To collect 25 L seawater samples from each JONSIS station.
1. To assess water quality in the vicinity of a major chemical (liquid) disposal ground off R Tees by bioassay using embryo development of the oyster, Crassostrea gigas. Water samples to be taken at intervals while steaming over a grid (2-3 days).
2. To monitor, over the same grid, pH, dissolved oxygen, salinity,
temperature and turbidity in surface waters using the environmental package and also salinity, temperature and turbidity through the water column at intervals (2 -3 days concurrently with Aim 1).
3. To study the dispersion of waste discharged from pipelines off Boulby, North Yorkshire and off Horden, Durham by means of a towed transmissometer (1-2 days)
4. To study,by grabbing, the distribution and abundance of colliery waste in sediments in the vicinity of the propsed sewage sludge dumping ground off the R Tyne (1 day).
5. To collect, by grabbing and/or Agassiz trawling, benthic organisms for chemical analysis from colliery waste disposal areas and from off the River Tyne.
6. "Routine" monitoring of sewage sludge disposal grounds (a) off R Humber (Spurn Head) and (b) in the outer Thames Estuary (Barrow Deep); to collect sediment samples from a limited number of stations for physical and chemical analysis and benthos and fish for chemical analysis by grabbing, dredging and/or trawling.
7. To conduct additional trawling off R Humber and also off Mablethorpe to collect fish for chemical analysis for the UK monitoring programme.
8. To conduct a 26 h hydrographic station at the Roughs Tower dumping ground (off Harwich).
9. To investigate, by grabbing, a designated disposal site off Amble.
10. To collect surface and bottom water samples and sediment samples for hydrocarbon analysis from selected sites near rigs and wellheads in the Indefatigable Field.
