PurposeResearch
Objectives1. At 53° 32' N 3° 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 sea bed frame for a 600 kHz ADCP to measure the mean current profile, pressures and
directional waves.
c) A CEFAS SmartBuoy in a single point mooring with an Aanderaa temperature and
conductivity logger at 10 m below the surface.
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 (recovery a).
e) A sea bed frame fitted with a 1.2 MHz ADCP, SonTek ADV, LISST-100 and Sontek
coherent Doppler on loan.
f) A CEFAS SmartBuoy in a single point mooring with an Aanderaa temperature and
conductivity logger at 10 m below the surface.
g) A development spar 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 suspended sediment at all stations and for chlorophyll at
selected stations.
