PurposeResearch
Objectives1. At 53 32N 3 21.8W, half a mile west of the Mersey Bar Light Vessel (site A)
To recover: (a) A sea bed frame for a 600 kHz ADCP (waves ADCP); (b) A CEFAS SmartBuoy (with cellulose bags) in a single point mooring. To deploy: (c) A sea bed frame for a 600 kHz ADCP (waves ADCP); (d) A CEFAS SmartBuoy (with cellulose bags) in a single point mooring.

2. At 53 27N 3 38.6W
To recover: (e) A sea bed frame for a 600 kHz ADCP (waves ADCP); (f) A CEFAS SmartBuoy (with cellulose bags) in a single point mooring. To deploy: (g) A sea bed frame fro a 600 kHz ADCP (waves ADCP); (h) A CEFAS SmartBuoy (with cellulose bags) in a single point mooring (i) A telemetry surface buoy.

3. To conduct a CTD/LISST survey of 34 sites 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, suspended sediment and for chlorophyll at selected stations. To obtain near surface and bed water samples for nutrient and suspended sediment determination.

4. Collect 10 vertical net hauls at mooring site A.

5. To recover a directional wave buoy at 53 22.6N 3 14.1W, off Hilbre Island.

Measurements 
Physical oceanography 
CTD stationsQuantity: number of stations = 35
Description: The Sea-Bird 911 CTD recorded downwelling PAR light levels (CEFAS light sensor) and transmittance, measurements were taken to within an estimated 3 m above the bed
CTD stationsQuantity: number of stations = 38
Description: The Sea-Bird 911 CTD recorded temperature and conductivity, measurements were taken to within an estimated 3 m above the bed
Chemical oceanography 
OxygenQuantity: number of stations = 35
Description: The Sea-Bird 911 CTD recorded oxygen (no calibration samples), measurements were taken to within an estimated 3 m above the bed
PhosphateQuantity: number of stations = 35
Description: Water samples were taken from the near surface and near bed bottles and frozen for nutrient analysis by NOC
NitrateQuantity: number of stations = 35
Description: Water samples were taken from the near surface and near bed bottles and frozen for nutrient analysis by NOC
SilicateQuantity: number of stations = 35
Description: Water samples were taken from the near surface and near bed bottles and frozen for nutrient analysis by NOC
Contamination 
Suspended matterQuantity: number of stations = 35
Description: Water samples were taken from the near surface and near bed bottles and were filtered to determine suspended sediment load and calibrate the CTD transmissometer. Water samples from the second near surface bottle from stations 1 and 21 were filtered for suspended sediment determination and some filtrate was preserved with mercuric chloride for nutrient determination by CEFAS. A LISST-25 and a LISST-100 particle sizer were fitted to the CTD
Biology and fisheries 
Phytoplankton pigs (eg chlorophyll, fluorescence)Quantity: number of stations = 35
Description: The Sea-Bird 911 CTD recorded fluorescence at 24 Hz. Measurements were taken to within an estimated 3 m above the bed. Water samples from the second near surface bottle from stations 1 and 21 were filtered for chlorophyll
Meteorology 
Other meteorological measurementsQuantity: activity duration in days = 1
Description: Parameters recorded every minute 3 m below sea level by the WS Oceans surface sampling system: Date, Solar Radiation, PAR, Air Temperature, Relative Humidity, Relative Wind Speed, Relative Wind Direction (zero indicates wind on the bow), Transmissance, Hull Temperature, Barometric Pressure, Fluorescence, Turbidity, Salinity, Minimum Air Temp, Maximum Air Temp, Wind Gust, GPS Time, Latitude, Longitude, Barometric Pressure Minimum, Barometric Pressure Maximum (mbar), and Conductivity sensor water temperature
