Tracking Orcas with Tech: 'The Images Took Our Breath Away'


The Dance Centre will showcase online performances in the lead up to International Dance Day on April 29.
The array of high-tech tools included aerial drones, electronic fish finders and data loggers equipped with satellite telemetry, a gyroscope, hydrophone and an underwater camera. Attached to the killer whales with suction cups, these devices allowed the scientists to record what the whales see and hear, as well as their movements in the water, and their diving and hunting behaviour.
The video clips, collected from above and below the water, samples of which can be viewed here were arresting. Some of the images took our breath away, says team leader Andrew Trites, a professor at the Institute for the Oceans and Fisheries Department of Zoology and the director of the Marine Mammal Research Unit at UBC. “It was amazing to watch the whales rolling through the water and moving in three-dimensions.” ....

A disease detective hopes to discover why British Columbia’s wild salmon continue to decline.

They maneuvered their boat to encircle the fish with a net and pulled them aboard. But something was wrong. Some fish swam strangely at the surface and rolled over. As the researchers performed quick gill biopsies before releasing the fish, some died while still in the net. Their catch was a mixture of healthy-appearing pink and coho salmon but the juvenile sockeye salmon were long and skinny, a sign of malnourishment, some with cloudy eyes, others with their eyes popping out of their heads.  ....
