For a second time, the world watched as Tahlequah, an endangered southern resident killer whale, struggled to keep her dead newborn calf afloat in the Salish Sea.

But with Ottawa failing to take urgent action to protect the 73 remaining orcas, a coalition of environmental groups is suing two federal ministers to push them to assume their legal responsibility and recommend an emergency order to save the West Coast icons.

Emergency protections for endangered southern resident killer whales are urgently needed because of increased oil tanker traffic from the expanded Trans Mountain (TMX) pipeline, says a coalition of conservation groups.

Six environmental organizations are formally petitioning Environment Minister Steven Guilbeault and Fisheries and Oceans Minister Diane Lebouthillier, urging them to recommend that cabinet issue an emergency order under the Species at Risk Act (SARA) to save the remaining 74 whales, said Margot Venton, nature program director of Ecojustice, a legal charity working for the environmental groups.

West Coast engineers aim to clear up acoustic smog impacting endangered killer whales

National Observer, Local Journalism Initiative Reporter

Editor’s note: In addition to being marine tourist destinations close to a principal British Columbian shipping lane, Cortes, Quadra and Read Islands are visited by both the northern and southern pods of Killer Whales

University of British Columbia engineers are working to help clear up the acoustic smog that hinders endangered orcas’ ability to gather information vital to their survival. 

Chronic underwater noise from shipping can drown out sounds marine mammals — such as the southern resident killer whales — use and rely on to communicate with each other, navigate, avoid danger or locate their prey.

Hums, growls and farts: Fish sound the alert

Fish have plenty to say and we need to make more of an effort to listen to them and understand what they’re talking about, researchers say. 

The hums, grunts, squeals and even farts made by soniferous, or noise-making, fish are a noteworthy part of the ocean soundscape, said marine ecologist Kieran Cox

The former University of Victoria researcher was part of an international team that combed through more than 800 studies to catalogue vocal species and created a publicly accessible global library called FishSounds

Straitwatch: the Discovery Island’s ‘whale police’

Canada’s National Observer, Local Journalism Initiative Reporter

A putrid stink wafts across the water and engulfs the Straitwatch vessel floating off the southern end of Quadra Island.

The Zodiac’s operator, Alex Forman, wrinkles his nose at the odour that hangs in the air, strongly reminiscent of fermented garbage.

“Whale breath,” he explains. “Humpbacks don’t brush their teeth much.”
