TMTW 2015: Three Month Continuous Measurement of Waves off the West Coast of Ireland During the Winter of 2015 University College Dublin

Three Month Continuous Measurement of Waves off the West Coast of Ireland During the Winter of 2015 University College Dublin 
Presenter: Frederic Dias University College Dublin 

 

The WAVEMEASUREMENT project is linked to the ERC Advanced Grant MULTIWAVE (www.ercmultiwave.eu). MULTIWAVE is an interdisciplinary project focusing on uncovering the fundamental mechanisms underlying the physics of rogue waves. The potential to improve the understanding of ocean rogue waves is hindered by the lack of reliability of measurements of extreme ocean waves. More specifically, the quality of the data and the sophistication of data analysis of existing measurements from conventional buoy sensors are still unsatisfactory for the detailed study of rogue waves. The key idea of WAVEMEASUREMENT is to implement rigorous calibration tests of wave measurement in an extreme environment.

 

As a test site, the Killard Point area (west coast of Ireland) has been chosen. The overall area is characterised by a mean tide of about 5m which can reach maxima of about 5.7m.

 

Because the experiment was aimed at defining the quality of the currently available wave measurements under extreme conditions, a Sentinel V ADCP and a Waverider buoy were considered for comparison. The ADCP was deployed on 9 February 2015 in the Killard Point area at 39m depth, at exact location 52° 47.696’N, 009° 34.149’W and recovered on 11 June 2015. The deployment and recovery were carried out by TechWorks Marine. Data processing has started and there are 80 days of continuous data. Unfortunately the Waverider broke and was not replaced.
