Deep Blue

Posted by on May 9, 2014 in Sighting Updates | No Comments

We were just recently sent some great photos of a blue shark that was sighted at the platform for Encana Corporation’s Deep Panuke natural gas field offshore Nova Scotia on August 31, 2011.  The Deep Panuke platform is off Sable Island, about 250km southeast of Halifax. Check out one of the photos below.

Last summer, with funding from the Deep Panuke Education & Training and Research & Development Fund, 20 juvenile blue sharks were tagged with acoustic tags off of Eastern Passage, NS by researchers from the Ocean Tracking Network (see below for more details) and Dalhousie University to better understand blue shark movements in the western North Atlantic. The tagging was part of a summer course for senior undergraduates at Dalhousie University and 23 students were trained in shark capture and tagging, as well as telemetry techniques. The study found that during the summer of 2013, the waters off of Eastern Passage appeared to be favoured by females and the blue sharks generally stayed around the Halifax area throughout the summer, autumn and winter. In the summer of 2014, 20 more juvenile sharks will be tagged to better understand the migratory pathways and hotspots of this top marine predator. To find out more about this study, please see the final report for the 2013 field season here.

The Ocean Tracking Network is a global monitoring network, headquartered at Dalhousie University, which examines local-to-global movements of marine wildlife such as sharks, eels, marine mammals, tuna, sea turtles and many other marine species, to provide a scientific foundation for sustainable oceans management.
