A couple of years ago, Professor Frederic Dias and some of his colleagues published a list of large scale wave events around the coasts of Ireland, linked with various causes, and from the historical record. It’s an interesting paper, and if you have any interest at all on sea behaviour around Ireland, it’s worth a look to get a picture of some of the weather/wave related impacts on the country historically. This is linked to the Multiwave project, page here.
They could do with a little help if you’ve experienced any extreme wave events. They’d be grateful if you could fill out the form linked on this page (pdf) or this one (word) and send it back to them.
