A group of Galway marine scientists recently completed a major sea survey off the south coast of Spain on board the RV Celtic Explorer.
The survey, entitled “Acoustic Monitoring from Ireland to Gibraltar Oceanic Waters Survey” or AMIGOS survey, was led by Dr María Pérez Tadeo (Chief Scientist), postdoctoral researcher at Atlantic Technological University (ATU).
Funded by the Marine Institute Ship-time Award the group began the survey in Lisbon, Portugal, on October 20th, and followed transects around the Gulf of Cadiz, passing through the Strait of Gibraltar and on to the Mediterranean.
One of the main aims of the survey was to contribute to data collection in acoustic monitoring of marine mammals and underwater noise as part of the EU-funded Horizon project STRAITS (Strategic Infrastructure for Improved Animal Tracking in European Seas).
STRAITS is led by the Northern Ireland-based Loughs Agency, and ATU is one of its lead partners with Dr Joanne O'Brien as principal investigator and María Pérez Tadeo as project manager.
Working on the AMIGOS interdisciplinary survey were scientists from the University of Galway, from the University of Southampton and from the Irish Whale and Dolphin Group.
“Besides the collection of the underwater soundscape, the group also conducted CTD stations in order to determine the salinity, temperature, and depth in the water column, water sampling to assess primary productivity, and seabird and marine mammal observations,”ATU says.
“The survey was also a great training opportunity for early career researchers and students who accompanied Drs O’Brien and Tadeo,”it says.
Speaking about the survey, Dr María Pérez Tadeo said it “provided a valuable opportunity to collect extensive data on marine mammals and underwater noise levels across European waters”.
“This data will provide baseline information, allowing us to compare noise levels across regions and assess the impact of human-made noise on marine life,” she said.
Dr Joanne O’Brien said it was “an excellent opportunity for the team to collect data for the STRAITS project, but also facilitate collaborations with other universities as well as offshore training for ATU postgraduates”.
