On April 22, 2009 Jean-Michel Cousteau’s PBS program, Ocean Adventures premiered the two part episode, “Call of the Killer Whale”.
Narrated by Chris Noth, the episode takes us on an adventure with Jean-Michel Cousteau, his son Fabien, and daughter Celine, as they went to both then northern and southern hemispheres to seek out whales in the Atlantic and Pacific Oceans.
Since orcas are the dominant species in the ocean, and we are the dominant species on land, Cousteau’s mission was to try and make the connection between humans and nature by comparing us with orcas.
Their journey began in the Pacific Northwest, speaking to John Ford, a Cetacean Research scientist and pioneer in orca acoustics, and Paul Spong, Research Director at OrcaLab, Canada. Ford spoke about how orcas communicate through many dialects and calls, and that we have so much to learn from these animals.
Spong discusses orcas large, complex brains. 40 years ago when he first saw an orca brain he asked, “What does this whale do with that brain?” He continues to ask this question today.
This would not be an orca-centric program without talking about Keiko, the most famous whale in the world. As shown in A Whale Of A Business, Keiko’s transition from young captive whale to movie star to old captive whale on the path toward returning to the ocean was a long, hard journey, but with the help of committed scientists and trainers, they returned him to the wild ocean waters.

While Keiko had not communicated with another orca in more than 20 years, another captive orca that was still using the calls from the pod he was taken away from.
Alexandra Morton of the Raincoast Research Society and Paul Spong discussed the resilience of Corky, the 43-year-old female orca that had been in captivity for 38 years. Although she communicated with Orky, another orca in captivity with her, she continued to try communicate with the pod she had not seen in almost 40 years.
One of the major studies Spong is trying to do at OrcaLab is pick out orcas individualized voices. While it is fairly easy for humans to recognize different voices, it is almost impossible with orca whales.

Part Two of the program takes Cousteau and his team to Norway, searching for orcas in the dark of winter. What they hoped to find was an orca feeding frenzy.
One team member, Holly Lohuis discusses the many places they’ve been around the world and asks Dag Vongraven, Senior Advisor as the Norwegian Polar Institute whether the orcas in Norway are similar to the ones we know in the Pacific Northwest.
“We have the same matrilineal system [in Norway]. We believe they are the same type of groups, but for us it seems to be a more fluid system. We don’t find these very permanent groups that you do in the Pacific Northwest.”
Jean-Michel Cousteau and his team went to Norway in the winter because, as Vongraven explained, “the spring spawning of Norwegian herring has been prime prey for the whales. As a consequence, there has been 500-600 whales at the same time.”

After Norway, the team went to Monterrey Bay, California to see the great gray whale migration that happens every spring. Killer whales prey on gray whale calfs because there are so many and they are very large and can feed 20-30 orcas at a time.
After witnessing a brutal feeding on a gray whale calf, the team headed back to British Columbia to continue their research on the west coast of Canada, the most studied orca population in the world. Jean-Michel and Celine Cousteau led their team to the “Land of the Killer Whale.”
The humans living in this area are very cautious in protecting the small population of whales that they know very well. Kenneth Balcomb, Senior Scientist at the Center for Whale Research explained, “For more than 30 years, we’ve known every individual [whale] that comes and goes, is born and dies here.”
In the last portion of the episode, there is an emphasis on salmon fishing, specifically, farm fishing and the toxins and other chemicals in farm-fished salmon that affects humans. In Robson Bight in British Columbia, salmon are an integral part of the coastal ecosystem that the orcas are a part of. The open-net pens that the salmon are kept in breed disease, infection, and parasites, and the antibiotics the fish are given to help combat disease negatively affect surrounding life, namely the orca whales, which cause them to leave to find good salmon, become infected with disease, starve, or in some cases, die (Salmon Farming).

The First Nations people that live on the coast explain that they lived off of the wild salmon, and those fish are quickly being taken away by salmon farmers.
John Ford explained to Jean-Michel that we need to listen to the lessons of the past: the First Nations caught wild fish and there wasn’t any pollution or disease among these waters. We must take that example and put it into action once again if we want to continue to see orcas on the coast, return this ecosystem to health, and find a cure for the future.
“Perhaps a way we can reach the public as empathy for a dramatic, exciting animal that’s found in all the world’s oceans, so if we can connect with them, then personal decisions might change.”
