Introduction

This report collates information from the BODC cruise inventory and oceanographic databases. It presents

Cruise Inventory Information

Long name RV Prince Madog (74P2) cruise PD20/02
Short name PD20/02
Objectives and Narrative 1. Deploy at 53deg 32'N 3deg 21.8'W:
Seabed frame with 600kHz ADCP to measure mean current profile; also fitted with transmissometer/conductivity/temperature logger;
Seabed frame with 600kHz ADCP to measure fast sample current profiles;
Single point mooring with temperature and conductivity loggers at 2, 5, 10m below surface.
2. Conduct CTD survey of 34 stations every 5 miles covering eastern Irish Sea to determine effects of rivers Dee, Mersey and Ribble on Liverpool Bay.
