This was going to be an interesting trip as
ex-hurricane Lorenzo was due to hit Ireland on the 3rd October and
cross to the mainland of the UK on the 4th as we were expected to
return. This storm had already broken records by reaching category
5 status and was the furthest north and east a hurricane of this
size had ever been recorded. By the time it hit Ireland it had been
downgraded to just a storm but was still expected to cause some
issues.
As things turned out, it was not that bad in the Irish Sea. On the
trip over the sea state reached state 7, making it tricky to spot
anything in the water. However, on the return trip the conditions
were much better, being sea state 2 most of the time. Maybe we were
in the eye of the hurricane the whole time?
Due to the conditions on the way over there was not anything seen
cetacean wise. There was one possible Harbour Porpoise that I was
90% sure of but this was not recorded as I was not completely sure.
On the return with better conditions three Harbour Porpoise were
spotted as well as a couple of Grey Seal as we left
Warrenpoint.
There were not large numbers of birds either.
However, the five Great Skua seen shattering my theory that there
was only one Great Skua in the Irish Sea! Maybe the storm had blown
them off course, and they would only briefly be there thus not
disproving my theory….
The most numerous bird species was Shag, due mainly to the 300
standing on an island just outside Warrenpoint!
I would like to thank the captains and the crews of the Seatruck
Precision and Performance for looking after me.
