RV Cirolana CIR3/79
Cruise summary report
|Ship name (ship code)||RV Cirolana (74CZ)|
|Cruise period||1979-03-13 — 1979-04-01|
|Port of departure||Grimsby, United Kingdom|
|Port of return||Grimsby, United Kingdom|
|Objectives||1. Radionuclide studies in the Irish Sea. Samples to be taken of the sea bed (including interstitial water) particulate suspended material and water. Particulate size distribution, suspended loads and radionuclides will be measured as appropriate. Velocity measurements using recording current meters will be made near the Windscale outflow and at two locations off the Scottish coast in the North Channel. The 137-Caesium in-situ measuring instrument will be used. Sea bed drifters will be released at selected localities.
Core samples for radionuclide analysis will be taken in the Clyde area.
2. To measure the distribution of selected dissolved and particulate
trace metals in the water over the Liverpool Bay sludge dumping ground and
off the Marchon chemical works sea discharge pipeline.
Surface sea bed samples to be collected at selected localities in the latter area.
3. If time and opportunity permits, water samples for trace element analysis will be collected in the vicinity of Scapa Flow.
