Marine Notice: UCD DAS Survey in Southern Irish Sea Off Wexford and Wicklow

24th November 2022

The RV Tom Crean will conduct the survey in the Arklow Bank area from Wednesday 30 November

Research survey TC22016 will be carried out in the southern Irish Sea off the Wexford/Wicklow coast by University College Dublin from next Wednesday 30 November to Friday 9 December, subject to weather and operational constraints.

The aim of this research project is to test novel low-impact marine sensors to aid in better understanding of seabed processes and sub-bottom conditions.

Survey works will be conducted on and around Arklow Bank by the State’s latest marine research vessel, the RV Tom Crean (callsign EIYX3), which will display appropriate lights and signals.

Within the defined areas, the vessel will be undertaking deployment of equipment and operation of acoustic sources during daylight hours, and sparker and multi-beam acoustic operations during the night.

All operations will be carried out in accordance with safe operating practices and MMO procedures and cognisant of fishing gear. All surface equipment will display appropriate lighting while deployed.

As the vessel will be limited in its ability to manoeuvre at times when undertaking operations, other vessels are kindly requested to keep a wide berth.

Mariners as also asked to note that a wind turbine was set on fire by a suspected lightning strike last month in the location of this planned survey and that there is a radio navigation warning in force. All vessels are requested to keep at least 500 metres clear of the turbine.

Maps and coordinates of the survey area as well as contact details can be found in Marine Notice No 79 of 2022, attached below.

Marine Science Perhaps it is the work of the Irish research vessel RV Celtic Explorer out in the Atlantic Ocean that best highlights the essential nature of marine research, development and sustainable management, through which Ireland is developing a strong and well-deserved reputation as an emerging centre of excellence. From Wavebob Ocean energy technology to aquaculture to weather buoys and oil exploration these pages document the work of Irish marine science and how Irish scientists have secured prominent roles in many European and international marine science bodies.
