RV Cirolana CIR1/78
Cruise summary report
|Ship name (ship code)||RV Cirolana (74CZ)|
|Cruise period||1978-01-04 — 1978-01-20|
|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. Special emphasis to be placed on samples from near the sea bed/water interface. Particulate size distribution, suspended loads and radionuclides will be measured as appropriate. At selected positions, near the Windscale outflow velocity measurements to be made at three levels using recording current meters. Sea-bed drifters to be released at selected localities.
2. To measure the distribution of 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 the latter locality.
A trace metal survey to be made of other regions of the Irish Sea as time permits.
3. To recover and relay the Humber and JONSIS current meter rigs.
4. To collect water samples for the measurement of radioactive caesium on
passage to and returning from the Irish Sea.
