TechWorks Marine plans to deploy four trawl-resistant bottom mounted acoustic Doppler current profilers (ADCP) frames in Castlemaine and Valentia off the coast of Co Kerry from this Monday 7 February.
Weather permitting, the Ocean Navigator (callsign EI018) will deploy the four trawl-resistant, bottom-mounted ADCPs frames — each of around one square metre in area — on the seabed for a minimum of one month and a maximum of two months, between this week and Monday 21 February.
They will be used to carry out water quality sampling surveys as well as vessel-mounted ADCP surveys at the same time as the deployments and these are tide and weather dependent and may cause a slight delay in the recovery of the seabed frames.
The ADCPs will be measuring currents through the water column at each location over the course of their month-long deployment. This data will be used to validate a hydrodynamic model being developed of the area for Irish Water.
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. Throughout operations, the Ocean Navigator will be displaying appropriate lights and shapes.
Details of the exact locations of the ADCP frames and other information for mariners are included in Marine Notice No 08 of 2022, which can be downloaded below.
