This video from Canada is called Bowhead Whales in Kugaaruk.
From National Wildlife Magazine in the USA:
Your answer could be that an astounding half of the U.S. seafood catch comes from the region—including 2.5 billion pounds of walleye pollock turned every year into imitation crabmeat, fish sticks and fast-food fish filets. Or maybe you know that Yup’ik, Inupiat and Aleut people have lived off the Bering Sea’s bounty for thousands of years. Or that ever since Russians happened upon the region’s Pribilof Islands in the 1700s, human beings have been altering its rich ecosystem. …
The exploitation began in the Pribilof Islands, which are critical breeding and staging areas 300 miles from the mainland. First Russians “ravaged the place,” says Springer, almost eliminating the islands’ fur seals and killing off entirely the local walrus and sea otter populations. In the mid-1800s, U.S. whalers took a huge toll on bowhead and right whales, and in the mid-1900s, several countries did large-scale, uncontrolled commercial fishing as well as additional whaling. In the Aleutian Islands, both the Steller’s sea cow and Steller’s spectacled cormorant were hunted to extinction.
Though the region’s fisheries are now intensively managed, and the hunting of birds and marine mammals is regulated, many species have decreased in number over the past quarter century. They include the spectacled eider and Alaska’s breeding populations of Steller’s eiders, both federally listed as threatened. Populations of Steller’s sea lions [see also here and here]—now listed as endangered in the western part of their range—harbor and fur seals, sea otters, ocean perch and several species of crab have declined, some dramatically. The reasons, elusive and controversial, could include the impacts of commercial fishing in addition to the long-term effects of whaling and natural shifts in ocean temperatures.

Cute But Deadly: Steller Sea Lions: here.
A new study suggests that the impact of predation on juvenile Steller sea lions in the Gulf of Alaska has been significantly underestimated, creating a “productivity pit” from which their population will have difficulty recovering without a reduction of predators: here.
Female Steller sea lions tend to breed near their birthplace. Familiarity with other females, geography may be crucial for reproduction: here.
