Cruise summary report
|Ship name (ship code)||RV Cirolana (74CZ)|
|Cruise period||1975-09-25 — 1975-10-23|
|Port of departure||Grimsby, United Kingdom|
|Port of return||Grimsby, United Kingdom|
|Objectives||1. To survey the distribution of selected dissolved and particulate trace metals in the water of the eastern North Atlantic between W. Euroge and the Azores. Nutrient salts and dissolved oxygen to be measured on trace metal sampling stations.
2. To collect hake for the analysis of selected pollutants from the Azores and off the Portuguese and Spanish coasts.
The above two aims are related to the activities of the ICES Working Group on Pollution Baseline and Monitoring Studies in the Oslo Commission and ICNAF areas.
3. The deployment of three free drifting data recording buoys (TWERLE) west of Ireland for tracking by satellite.
4. To lay a moored current meter station off the mouth of the River Tyne.
5. To collect water samples for the analysis of radioactive caesium.
