Cruise Inventory Information

Long name RV Prince Madog (74P2) cruise PD35/02
Short name PD35/02
Objectives and Narrative 1. At 53 deg 32' N 3deg 21.8' W, half a mile west of the Mersey Bar Light Vessel -
To recover
a) A sea bed frame for a 600 kHz ADCP to measure the mean current profile and pressures.
A pressure recorder, a transmissometer / conductivity / temperature logger and a SeaBird
MicroCat are fitted to the frame.
B) A CEFAS SmartBuoy in a single point mooring with an Aanderaa temperature and
conductivity logger at 10 m below the surface.
C) A CEFAS Datawell directional wave recorder (single point mooring). This recovery was
necessary to change a section of the mooring and to change the sampling scheme to record
statistics only so that the logger would last 6 months.

To deploy
d) A sea bed frame for a 600 kHz ADCP to measure the mean current profile and pressures.
A pressure recorder, a transmissometer / conductivity / temperature logger and a SeaBird
MicroCat are also fitted to the frame.
E) A sea bed frame for a 600 kHz ADCP (recovery 'a') to measure the mean current profile,
pressures and directional waves.
F) A CEFAS SmartBuoy in a single point mooring with an Aanderaa temperature and
conductivity logger at 10 m below the surface.
G) A CEFAS Datawell directional wave recorder (recovery 'c'), single point mooring.
2. To conduct a CTD / LISST survey of 34 stations every 5 miles covering the eastern Irish
Sea between the North Wales coast and Blackpool and the Lancashire coast and the Great Orme, to determine the effects of the rivers Dee, Mersey and Ribble on Liverpool Bay. To obtain calibration samples for suspended sediment at all stations and for chlorophyll at selected stations.

All of the mooring objectives were accomplished and 31 out of 34 CTD sites visited
