Objectives

1. At 53 32N 3 21.8W, half a mile from the Mersey Bar Light Vessel -
to recover:
A) A sea bed frame for a 600 kHz ADCP (waves ADCP).
B) A CEFAS Smartbuoy in a single point mooring.
To deploy:
C) A sea bed frame for a 600 kHz ADCP (waves ADCP).
D) A CEFAS Smartbuoy in a single point mooring.
E) A wave rider buoy.

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 salinity, transmittance and suspended sediment.

3. recover a sea bed frame from 53 23N 4 41.925W (off Holyhead) for ADCP, ADV and LISST deployed during CASIX cruise May 2004.
