The population of beluga whales that live in the Cook Inlet has been steadily declining in recent years.

That’s why they recruited an army of citizen scientists Saturday to count endangered beluga whales near Anchorage.Listen nowThere were 18 viewing stations scattered across Cook Inlet. At one of them just off the Seward Highway south of town, Brooke Faulkner, a college student, spotted a whale and a calf.“I was just talking and then all of a sudden I was like, ‘It’s right there!’” Faulkner said. She’s studying biology at a Homer-based semester program. “It was within like 50 feet of us.”Scientists estimate that there are about 330 belugas in the inlet, down from more than 1,000 in the 1970s. The federal government named Cook Inlet beluga whales as an endangered species in 2008.Biologists think hunting originally caused the decline. But even though hunting has stopped, the population hasn’t recovered, and scientists aren’t exactly sure why.“They just didn’t bounce back the way we expected they would. So the question is, once you remove that immediate source of mortality, if they’re not bouncing back from that, what else might be hindering them?” said Jon Kurland, a Juneau-based official with NOAA Fisheries, the agency charged with protecting belugas. “Is it food? Is it noise? Is it contaminants? Is it just something else that we haven’t thought of yet?”The process to list Cook Inlet belugas as endangered was contentious, in part because of fears that beluga protections could interfere with commerce in Cook Inlet.The inlet has offshore platforms producing oil and gas. There’s also a commercial fishing industry. And Anchorage’s port is a hub for food, cars and fuel shipped into the state. The state of Alaska and an oil company actually sued to block the beluga listing, though they lost.Now things are a little more cooperative. The state chairs a beluga recovery team alongside the federal government, and oil company workers looked for whales from their platforms in Cook Inlet on Saturday.Federal managers said they think events like the count can help build public support for belugas.“We all tend to care about things that are in our backyard, right? And things we can see,” said Donna Wieting, a NOAA Fisheries official who traveled to Anchorage from the Washington, D.C. area for Saturday’s count.Wieting said her agency tries to get people spotting other species, too. All along the West Coast, there are “Whale Trail” stations where people can look for orcas.Julia Grindstaff said that idea makes sense to her. She was also at Point Woronzof on Saturday — she moved to Anchorage a few years ago and said she got way more excited about belugas after she saw them in Cook Inlet.“I’d been landlocked in Illinois and Colorado, so when I came here and actually saw the belugas — oh my gosh, it was pretty amazing,” Grindstaff said. “It does make it more real to you than just seeing it on television or hearing about it.”Grindstaff said she calls the belugas the “ghosts of the Inlet,” because of how quickly and smoothly they rise out of the water.Organizers said just under 2,000 people showed up to count them Saturday, and spotted an estimated 100 whales.
