Ship name (ship code)RV Cirolana (74CZ)
Cruise identifierCIR5/94
Cruise period1994-04-19 — 1994-05-11
Port of departureLowestoft, United Kingdom
Port of returnLowestoft, United Kingdom
Objectives1. Survey plankton populations and hydrographic structure from the Malin Shelf to the North Channel for evidence of transport of copepods into the Irish Sea.
2. Test new Scanfish and Optical Plankton Counter (OPC) undulator systems and compare with Dutch electronic particle counter.
3. Deploy moored current meters for studies of water movements and production in the northern Irish Sea.
4. Sample fish eggs and larvae in relation to physical domains in the northern Irish Sea for growth studies.
5. Continuous monitoring of surface chlorophyll and regular measurement of column primary production in relation to modelling studies.
6. Observation and recording of live phytoplankton and grazing using high magnification video.
7. Collect copepod samples from the northern North Sea, west of Scotland, Malin Shelf and Irish Sea for studies of genetic origins.
