SHARKS | Green Marine


Scoil Cholmcille, Greencastle



At 6m, Green Marine is the largest and most placid of the satellite tagged sharks thus far. Due to her docility, we captured excellent video shots and fin photographs prior to tag deployment. The shark remained feeding on the surface for at least one hour following the tagging event. She was also the first to establish a connection with overhead satellites and relay data back from the tag.

 UPDATE:  the satellite transmitter from this shark popped off prematurely on October 2, 2012 at 01:50:25. It was found in the Irish Sea (51.299N, 005.789W). However, the tag did record sufficient information to recreate movement tracks and provide information on depth.

The title ‘Green Marine’ was bestowed on the shark tagged near Greencastle by a series of elimination votes.


Greencastle is home to one of Ireland's largest fishing fleets, the BIM National Fisheries College and an inspiring Maritime Museum. Maritime heritage is strong here, as a majority of population works in or services the marine sector. In July 2012, Greencastle also hosted the start of the final leg of the Round World Clipper Race.
