#MarineNotice - TechWorks Marine are deploying three trawl-resistant bottom mounted acoustic Doppler current profiler (ADCP) frames at three locations in Donegal Bay from this week.
The frames, which will be on the sea floor between now and June, are being deployed as part of the oceanographic monitoring programme for the Department of Agriculture, Food and the Marine.
Scheduled for deployment earlier this week on Monday 27 March, the frames will be left in the water for a minimum of one month before being retrieved.
The vessel Dulra na Mara (Callsign EIFS6) will be used for both deployment and collection of the frames. The vessel will be listening on VHF Channel 16 throughout the project.
The frames are 2m by 1m and will remain on the seafloor for a period of up to 90 days, after which each frame will be retrieved by the acoustic release of a pop-up buoy allowing for its recovery.
There will be no surface marker during the extent of deployment so vessel traffic will not need to avoid the area but should be aware of its presence.
