Marine researchers have successfully recovered a series of seismometers from the Atlantic Ocean, which will provide data on a variety of activities, in the depths of Irish coastal waters.
Scientists at the Dublin Institute for Advanced Studies spent two weeks collecting a total of 14 devices, which were deployed in 2018. Last night they returned to the port of Galway.
Four other recorders will be brought ashore in the coming months.
The seismometers were placed at the bottom of the ocean, in various places, covering thousands of kilometers. They will be used to measure movements on the Atlantic floor and to record acoustic waves in the water.
In addition to helping shed light on the nature and history of the ocean floor, the data is expected to provide insight into the movements of marine life, such as large baleen whales.
The information will also help investigate the potential to develop tsunami warning systems.
The devices had been scheduled to run until spring 2020 and had to be retrieved at this time, to safeguard the data that had been collected.
A team of six scientists and a crew of 15 members in the Marine Institute RV Celtic Explorer participated in the expedition.
Seismometers have waterproof memory cards that have recordings collected over the past 19 months.
The project was co-financed by Science Foundation Ireland, the Geological Survey Ireland and the Marine Institute.
Work on a detailed analysis of the information that has been collected will begin in the coming weeks.
