Here you will find the position information for the sharks we have tagged with remote tracking transmitters. We deployed both Wildlife Computers PAT-MK-10-F tags and SPOT5 tags in 2012 and 2013, and plan to continue in the near future. These tags offer the latest technological advance in tracking free living marine species, and allow us to track larger movements, like migration, over longer periods of time.  

​

Mark/recapture, plankton- and distance-sampling surveys are undertaken in parallel with telemetry deployments. These allow us to monitor long-term residence and seasonal return to study locations, estimate local population sizes, and understand how environmental factors such as prey field might affect basking shark movement patterns. Such data contributes to our goal of supporting the implementation of a sustainable management initiative for the species in Irish and Atlantic waters. 

​

The "Shark Tracker" project also serves to link our research and outreach efforts. Once tagged, each shark is named and adopted by a local coastal community or organization. These names represent the character of each associated group and the close association they have with the marine environment and their coastal heritage. The shark tracks can then be observed over time on this page.
