| Ship name (ship code) | Prince Madog (74PD) |
| Cruise identifier | PM11/98 |
| Cruise period | 1998-11-16 — 1998-11-19 |
| Status | Completed |
| Port of departure | Menai Bridge, United Kingdom |
| Port of return | Menai Bridge, United Kingdom |
| Purpose | Research |
| Objectives | This cruise was run as part of a NERC funded project entitled 'Holocene palaeoceanography of shelf seas: long-term (10***3 - 10***4 years) seasonal stratification dynamics'. The aim of this project is to generate a record of environmental change relating to development of seasonally stratified water in the Celtic Sea during the Holocene.
The aim of this cruise was to collect a second set of multicores from the sites already selected during cruise 7/98. These sites are to be examined for changes in the seasonal vertical distribution of benthic foraminifera and for seasonal variability of environmental conditions at each site. An additional aim was to collect plankton samples from the surface waters at these sites for dinoflagellate analysis and throughout the water column for planktonic foraminiferal analysis. |

| Measurements | |
| Physical oceanography | |
| CTD stations | Quantity: number of profiles = 7 Description: CTD (Neil Brown system) used for S, T, pressure and oxygen concentration. Water samples taken 10m from bed for calibration of the CTD and oxygen isotope measurement. Large plankton net attached to underside of CTD and therefore sampled entire water column for foraminiferal analysis. |
