Cruise summary report

Cruise Info. 
Ship name (ship code)RV Cirolana (74CZ)
Cruise identifierCIR4B/96
Cruise period1996-04-12 — 1996-04-26
StatusCompleted
Port of departureLiverpool, United Kingdom
Port of returnLowestoft, United Kingdom
Objectives1. To carry out SCANFISH trials and a survey of the NW Irish Sea plus, if time and weather permit, extend this out to the Malin Shelf.
2. To collect simultaneous OPC (optical plankton counter) and net samples of plankton for comparison of size spectra.
3. To carry out a TTN (Tin Tow Net) grid of the NW Irish Sea.
4. To estimate primary and secondary production rates in different domains.
5. To maintain continuous records of T, S, chlorophyll and measure surface nutrient levels.
6. To deploy instruments at DANI mooring Station 45 (NW Irish Sea).
7. To recover ARGOS buoys deployed during the previous half of the cruise.
8. Following the Sea Empress oil spill, complete a TTN grid south from Milford Haven and across the Bristol Channel to provide an indication of egg and larvae distributions and enable comparison with previous years.
