|---|---|
| Short name | PD11/05 |
| Objectives and Narrative |
1. 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 600kHz ADCP (waves ADCP); (b) A CEFAS SmartBuoy; (c) A sea bed frame for a 1.2 MHz ADCP (telemetry ADCP); (d) A single point toriod mooring. To deploy: (e) A sea bed frame for a 600 kHz ADCP (waves ADCP); (f) A CEFAS SmartBuoy in a single point mooring. 2. At 53 27N 3 38.6W To deploy: (g) A sea bed frame for a 600 kHz ADCP (waves ADCP); (h) A marking toriod in a single point mooring. 3. At 53 27N 3 30.2W To recover: (i) A sea bed frame for a 600 kHz ADCP (Dee ADCP). This was deployed as part of the Dee experiment. 4. 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 Lanashire 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. 5. To collect 10 vertical net hauls at mooring site A. 6. To conduct a 25 hour station at 53 32N 3 21.8W with CTD profiles recorded every half hour and surface and bed water samples taken every hour. |

| CTD stations |
Quantity:
number of stations =
3
Description: of CTD grid visited. CTD recorded downwelling PAR light levels (CEFAS light sensor), temperature, conductivity, transmittance, oxygen (no calibration samples) and fluorescence at 24 Hz. Water samples were taken from the near surface and near bed bottles and frozen for nutrient analysis by SOC (nitrate, phosphate, silicate), and also were filtered to determine suspended sediment load and calibrate the CTD transmissometer. Water samples from the second near surface bottle from stations 1, 5 - 9 and 11 were filtered for chlorophyll and suspended sediment determination and some filtrate was preserved with mercuric chloride for nutrient determination by CEFAS. |
