1 Automated In-Situ Water Quality Monitoring Report Issued by the North of Ireland Joint Agency Coastal Monitoring Programme. For further information and data access please visit our website at: Date of issue: 13 Apr 21 Index: Pages Belfast Lough Quoile Strangford Lough North Strangford Narrows ** NEW MOORING Larne * All instrumentation in Carlingford, Lough Foyle, Fad and the North Coast have been recovered for the winter period for essential maintenance and upgrades. Lagan buoy recovered for inspection and repair. North Coast hardware rebuilt and deployed 1/3/1 ** New mooring at Larne - see Larne page for link to real time data The Loughs Agency purchased the 6 Environmental Monitoring hardware currently operating in the sea Loughs Foyle and Carlingford and the system in the freshwater Lough Fad East, Co. Donegal. Four of these were purchased under the EU INTERREG III fund. The Agency has contracted the management and maintenance of these to AFBI. NIEA contributed towards the Environmental Monitoring hardware currently operating in Belfast and Strangford Lough and the impoundments of the rivers Lagan, and the Quoile. The Agency has contracted the management and maintenance of these to AFBI.

2 In Situ Water Quality Monitoring Report: Belfast Lough Issued by the North of Ireland Joint Agency Coastal Monitoring Programme. For further information and data access please visit our website at: Data report start date: 5 Apr 21 Data report finish date: 29 Mar 21 Date of issue: 13 Apr 21 Belfast Lough is a shallow semi-enclosed marine bay situated at the mouth of the River Lagan on the eastern coast of Northern Ireland and has a catchment of 9 km 2. The inner area of the Lough comprises a series of mudflats and lagoons whilst the outer area is composed of mainly rocky shores with some small sandy bays. The inner area of the Lough has historically been identified as being hypernutrified (as a result of anthropogenic impacts) and subject to eutrophication. A modified SeaBird 19+ instrument is moored in the inner lough close to the navigation channel, this package is occasionally supplemented with a remote access water sampler for nutrient sampling. Disclaimer Data is automatically updated to these reports (and the website) with minimal expert reviewing to allow the rapid dissemination of high resolution near-real-time data to interested parties. This data must be viewed as provisional and used for interpretive purposes only; the data has not been thoroughly reviewed or edited and data corruption will occur as a result of instrument fouling, drift or failure. Higher resolution approved and reviewed data may be made available by direct request. Data are reviewed and checked against other methods of measurement to ensure accuracy and may therefore be subject to change or exclusion at a later date.

For further information and data access please visit our website at: Natural tidal fluctuations in the Quoile Pondage are modified by the tidal barrage located at the mouth of the river where it meets Strangford Lough. The estuary is periodically stratified, accentuated by the saline water trapped as a layer under the freshwater riverine flow. Two Valeport 66 monitoring instruments are located in the main basin of the pondage near to the barrage; one instrument is near surface whilst the other is near-bottom. Data is automatically updated to these reports (and the website) with minimal expert reviewing to allow the rapid dissemination of high resolution near-real-time data to interested parties.

For further information and data access please visit our website at: Data report start date: 5 Apr 21 Data report finish date: 12 Apr 21 Date of issue: 13 Apr 21 Strangford Lough is a large almost land-locked marine lough on the east coast of Northern Ireland. The Lough has a high-water area of 12. Km 2 of which approximately 3% is intertidal. The Lough serves a catchment of Km 2 with two main freshwater inputs at Comber and Downpatrick. Depths range from around 1 m to over 6 m, with the northern end of the Lough having large areas of sand and mud flats and the southern end with an km long, deep and fast flowing channel which connects the Lough to the open sea. A Valeport 6 instrument is moored under a buoy in the northern end of the lough just south of the Boretree Islands.
