Ship name (ship code)RV Cirolana (74CZ)
Cruise identifierCIR5B/96
Cruise period1996-05-19 — 1996-06-03
Port of departureBarrow-in-Furness, United Kingdom
Port of returnLowestoft, United Kingdom
Objectives1. To recover, service and redeploy minipods in the north-east Irish Sea.
2. To determine the effect of trawling on the remobilisation of surface sediments, via radiochemical and geochemical sampling of sediment and water.
3. To carry out ultrafiltration experiments to asses sediment/water interface and radiocolloidal behaviour from disturbance of surface sediments by fishing trawls.
4. To characteris the trawling site through Sidescan sonar and towed video survey.
5. To collect a series of Kaston cores for the purpose of quantifying the budget of artificially occurring radionuclides in the sub-tidal sediments of the Irish Sea.
6. To recover tetrapod, minipods, quadapods and current meters from the north-east Irish Sea.
7. To deploy and recover 5 Minipods (with syringes) and Decca Argos drifters around Area 107/Race Bank in the Outer Wash to observe, measure and sample sediment plumes from dredgers.
8. To undertake resuspension studies in the vicinity of the Race Bank dredge site.
