Geohazard Investigation within the Irish Sea utilizing Seismic and Seabed Mapping Methods (GIST)

twenty fourth October – sixth November 2019


The GIST survey is now nicely and actually underway. As we come to the top of our second day on the Irish Sea, now we have already performed some good science and climatised ourselves to life on-board the RV Celtic Voyager for the following few weeks.

I’m a 3rd 12 months PhD pupil from NUI Galway, finding out marine acoustics and oceanography. This morning, with the skilled assist of the Voyager’s crew, we managed to deploy three moorings as a part of my PhD venture. Every mooring has three hydrophones and an information logger hooked up. These devices are mainly like a cassette recorder and microphone (for individuals who bear in mind cassette tapes) besides they work underwater. I hope to listen to a number of completely different noises like from passing ships or trawlers and maybe from our personal geophysics survey. We would even get to listen to some dolphins vocalising, if there occur to be any shut by. It can be crucial for me to know the main points of artificial sound within the ocean. It’s classed as a pollutant and so wants monitoring on account of its potential to hurt or disturb marine mammals.

We at the moment are tearing via our geophysics survey, which consists of assorted strategies of taking a look at, and beneath the seabed. Our science group has already surveyed three sunken shipwrecks, however extra about that in a later weblog.

Three of our group are new to ocean-based analysis and are settling into ship-life very nicely. To date, the climate has stayed calm and none of us have been examined by the weather, though now we have simply heard that issues may change for the worst by Tuesday. As ever, the blokes from the RV Celtic Voyager are taking care of us rather well and we’re consuming like kings and queens.

Total, we cowl a various vary of scientific pursuits on this multidisciplinary venture and we hope some fascinating collaborations will spark from the outcomes we discover. Keep tuned for extra tales and data from the GIST group’s adventures on the Irish Sea.
