Ferry Surveys

Irish Ferries to help EcoJel map jellyfish blooms



Since 2009, the EcoJel team in collaboration with Irish Ferries have conducted regular ferry surveys across the Irish Sea to monitor jellyfish blooms. It may seem like a strange thing to do, but ferries offer an ideal platform from which to make surface observations of jellyfish. Quite simply you look over the side of the ferry and record the number of jellyfish you see as you sail along!

Importantly, observations of jellyfish from ferries provide an excellent way of mapping the distribution of jellyfish over very large areas such as the Irish Sea. Surveys from 2009 and 2010 have highlighted the fact that jellyfish are not restricted to coastal areas but are present all across the Irish Sea. They also confirmed that the Lion’s Mane jellyfish were far more abundant in 2010 than in 2009.
Considering that jellyfish may play important roles in marine ecosystems it is important that we collect long term jellyfish data over entire seas so that we can determine if their abundance is decreasing or increasing with climate change.
