Feds give $11M to Dalhousie ocean project that employs seals as researchers

Ottawahas announced five years'worth of funding for aHalifax-based aquatic research networkthat includes gatheringinformation from the depths of the ocean using wired seals.

Andy Fillmore, the Liberal MP for Halifax, announced$11.4millionfor Dalhousie University'sOcean Tracking Network at an eventMonday.

The money, from the Canada Foundation for Innovation, is part of $328 million in federal fundingbeing doled out to major research projectsand scientificendeavours across the country.

"OTNresearch generates incredibly important information about climate change, the impact of offshore development," saidFillmore.

"This knowledge is used to guide themanagement of responsible fisheries policies and understand the sustainability of the world oceans."

TheOcean Tracking Network builds and deploys Canadian-designed acoustic receivers and oceanographic monitoring equipment around the world.

Its sensorstrackthe movement of more than 100 at-risk and commercially important species.

Putting grey seals to work

Sara Iverson, the network's science director, saidtechnology has advanced to the point where researchers are now putting the grey seal herd on Sable Island to work.

Scientists have attached mini receivers and Bluetooth linksto the large mammals that transmitdatagathered underwater to satellite when the seals surface.

"It'sa lot less expensive putting it on the animal because they are going to be running around the ocean anyway," said Iverson.

"They can go to depths of the oceans in times of the year where it's too dangerous or costly to use expensive ship time."

Exploring the ocean

The sensors provide basic data on ocean conditions throughout the water column and also record when an animalwith a tag swims by a seal carrying a receiver.

Scientists have found that grey seals and bluefin tuna are targeting the same foraging hotspots for the same prey.

Masters student Benia Nowakrecentlyreturned from Sable Island, where she started recovering tags from thegrey seal herd.

"I think it's really important," she said."I think we don't know enough about the biology of the ocean, about how these species are moving.

"The more we know about them, the better we can manage the species and oceans overall."
