Study reveals 30% decline in Alaska humpbacks in last decade

Wildlife biologist Janet Neilson keeps a close eye on Alaska humpbacks. For the National Park Service whale monitoring program, she keeps a count of the whales that migrate up from Hawaii to feed in Glacier Bay and Icy Strait every summer.

During the summers between 2014 and 2018, she and researcher Chris Gabriele, who has led the park’s monitoring program for three decades, noticed something was off.

“Young whales, calves went missing. We had whales in the prime years of their lives go missing. And we certainly had some older whales go missing as well,” Neilson said. “But it really seemed like it hit all the whales.”

Neilson is one of 75 co-authors on a new study, which finds that almost 7,000 North Pacific humpbacks went missing between 2012 and 2021 — a 20% drop-off from the peak population of more than 33,000. Researchers believe they starved to death during the record-setting marine heatwave known as “the blob.”

Naturalist Ted Cheeseman is the one who brought all the whale researchers together. He’s the founder of Happy Whale, a photo database that uses artificial intelligence to quickly identify individual whales by the unique black-and-white patterns on the underside of their tail fins, or flukes. With Happy Whale, Cheeseman set out to do a simple population count.

“But when we first saw these numbers, it turned a population study into a climate study,” Cheeseman said.

That’s because the database revealed a sharp decline in humpbacks that coincided with “the blob,” which spiked ocean temperatures from Alaska to California between 2014 and 2016, killing fish, seabirds and more than 30% of Alaska’s humpbacks.

Climate change may complicate the species’ conservation success story. Back in the 1990s, Cheeseman worked as a tour guide in Antarctica. And he said humpbacks were hard to come by back then.

“We didn’t see many whales at all,” Cheeseman said. “We did, however, visit some of the largest whaling stations that were ever built — you know, they’re factories. Absolutely factories to turn living whales into product.”

Commercial whaling pushed humpbacks to the brink of extinction, but their populations in the North Pacific have boomed since it ended. Humpbacks were taken off the endangered species list in 2016. But around that same time, researcher Heidi Pearson was seeing the whales around Juneau get skinnier and skinnier.

Pearson, who researches at the University of Alaska Southeast, says these whales are usually more adaptable than other marine species. They can travel long distances to find food. And their diet is flexible.

“So the fact that they still declined due to what we think is lack of prey means that it must have been really bad,” she said.

She says she still believes in the resilience of humpbacks. But the study’s results make it clear that the species is feeling the pressure of warming driven by the burning of fossil fuels.

“I really learned a lot about the fragility, actually, of the ocean system to this warming,” Pearson said. “Animals and systems are resilient, but clearly during the heatwave they reached this tipping point.”

For Neilson, in Glacier Bay, the decline emphasizes the need to protect humpbacks even when their populations seem healthy. Though they’re recovering in Glacier Bay, she says, they’re still not back to their pre-heatwave levels. And they’re also frequently threatened by ship strikes and entanglements in fishing gear near the coast.

“It’s important to realize that the whales that we do see out on the water these days are survivors of a major ecological disruption,” Neilson said. “Those survivors deserve protection because more heat waves are coming.”

As those heatwaves come, real-time population monitoring for humpbacks may be more important than ever bef0re. The whales, which are large, coastal animals that are easy to track, can be indicators of overall ecosystem health in a rapidly changing ocean.

Technology like Happy Whale can help researchers better track whales as they migrate all across the North Pacific. The new study pulled more than 200,000 fluke images from the database, which were collected from researchers and more than 4,000 citizen scientists.

“The scale of problems that our world is facing today within the environmental realm — climate change being the biggest one — they’re only going to be solved by collaboration,” Pearson said. “No one can do it alone, in their one study site.”

Officials with the University of Alaska have tapped the commander of the U.S. Army 11th Airborne Division’s Arctic Aviation Command as the new permanent chancellor of the University of Alaska Fairbanks.

Col. Russell “Russ” Vander Lugt was selected from four finalists after an eight-month search process. He will be the top executive of Alaska’s leading research institution, which describes itself as “America’s Arctic university.” He will replace interim chancellor, and former U.S. Ambassador to the Arctic, Mike Sfraga, who succeeded former chancellor Dan White who announced his retirement in May of last year.

Vander Lugt is a senior U.S. Army officer, an Arctic scholar and UAF alumni, with over two decades of executive leadership experience, according to a university announcement on May 27. He has served as commander of the 11th Airborne Division’s Arctic Aviation Command at Fort Wainwright in Fairbanks since Aug. 2024.

“I’m humbled to be selected to lead the University of Alaska Fairbanks during this pivotal time,” Vander Lugt said in a statement with the announcement.

“I look forward to leading through trust, transparency, and teamwork as we see Alaska and the Arctic transformed through education, research, and public service. I’m committed to building on the strong foundation Chancellors Sfraga and White have established, and working closely with university leadership and governance to support and advance UAF’s mission,” he said.

Vander Lugt will step into the permanent chancellor role on Sept. 8. Sfraga’s last day was Friday, and university officials have selected Larry Hinzman, director of the UA Arctic Leadership Initiative, to serve as interim chancellor through the summer.

Vander Lugt has had a long career with the U.S. Army in various roles in Alaska, where he is stationed in Fairbanks, and across the U.S. His resume lists deployments to Europe and the Middle East.

He served in executive leadership roles that include the Alaskan Command, a division of the U.S. Northern Command, the 601st Aviation Support Battalion, and the 1st Stryker Brigade Combat team. He also taught history and military leadership as an assistant professor at the U.S. Military Academy at West Point and was a professor of military science and department chair at Embry-Riddle Aeronautical University in Prescott, Arizona.

He holds a master’s degree and doctoral degree in Arctic and Northern Studies, which he completed in 2022 at the University of Alaska Fairbanks.

Vander Lugt’s hire is the latest in major leadership changes in the University of Alaska system — former UA President Pat Pitney retired last month and former university attorney Matt Cooper was named as her successor. Cooper will begin as university president in early August, and Michelle Rizk, vice president of university relations and chief strategy, planning and budget officer, is serving as interim president. Cheryl Siemers was appointed permanent chancellor of the University of Alaska Anchorage in March, after serving as interim chancellor since the retirement of former chancellor Sean Parnell last year.

Vander Lugt’s base salary will be $309,000, according to the university’s announcement.

The University of Alaska Fairbanks serves roughly 7,500 students. It employs more than 800 faculty and nearly 2,000 staff across urban and rural campuses in Fairbanks, Kotzebue, Nome, Bethel and Dillingham.

Photos show Alaska National Guard plane damaged in Iran war theater


The 168th Wing of the Alaska Air National Guard hosts a naming ceremony at Eielson Air Force Base on July 31, 2025 showcasing the KC-135 aircraft “Tetlin.” Photos of this Stratotanker with apparent shrapnel damage connected to Operation Epic Fury circulated online at the end of May 2026.

A plane belonging to the Alaska National Guard appears to have been damaged during operations connected to Operation Epic Fury as part of American military efforts against Iran, according to online reports. Defense officials have so far declined to confirm whether Alaska National Guard personnel or equipment are taking part in the campaign.

Last week, defense industry news outlet The War Zone published photos of a KC-135 Stratotanker transiting through a British airbase. In the pictures, made by photographer Andrew McKelvey, the rear bottom of the fuselage and wing stabilizers are “peppered with temporary shrapnel damage repairs‚“ according to The War Zone’s article. The plane also appears to be missing its refueling boom, the proboscis extending from under the tail to pump off fuel to other aircraft.

In the photographs, the Stratotanker’s tail number is visible, identifying the refueling plane as belonging to the Alaska Air National Guard’s 168th Wing, based at Eielson Air Force Base outside of Fairbanks. The wing’s mission includes aerial refueling. That’s the tactic of large planes unloading vast quantities of fuel to aircraft, ranging from fighter jets to rescue helicopters, in midair.

Pictures from a different photographer published last week by another blog, The Aviationist, show the same plane. The tail includes the letters “AK” painted above a white polar bear.

In addition to the photographs, the reporting from The War Zone is based on publicly available flight data and social media posts scraped from a variety of sources.

According to information from Flight Radar 24, the Stratotanker left Eielson on March 5, just days after the U.S. and Israeli militaries began bombing Iranian targets on Feb. 28. Through March, according to public flight records, the plane was based at Ben Gurion Airport southeast of Tel Aviv, where, according to The War Zone, dozens of American refueling aircraft were staged as part of Operation Epic Fury.

There are no public flight records connected to the Stratotanker through April and most of May, until it appeared to fly through England on the way to the United States at the end of last month.

It is not clear how many Alaska Air National Guard planes, personnel or units are currently deployed in connection to the war effort against Iran.

A spokesperson for the Alaska National Guard referred all questions about Operation Epic Fury to the U.S. Central Command.

A spokesperson for CENTCOM, headquartered at MacDill Air Force Base in Florida, declined to answer questions on the record or provide any specific information about Alaska National Guard units deployed as part of ongoing military operations, citing the need to protect service members and operational security.

The Alaska National Guard has posted no informational releases or pictures connected to an overseas deployment during the last few months.

Much of Operation Epic Fury has been waged by military aircraft, and aerial refueling is critical to keeping planes supplied during long flights. A May 12 report from the Congressional Research Service composed of public damage reports to U.S. military aircraft noted that among the 42 records of damage or losses were seven KC-135 Stratotankers, though the findings were published before photos emerged of the Alaska-based plane. The report noted that the Defense Department “has not published a comprehensive assessment of combat losses” from Operation Epic Fury.

The tail number is associated with a Stratotanker manufactured in 1964, the year before Boeing ceased making them. All of the nearly 400 KC-135s currently in operation within the American military date back to that era of the Cold War.

The aircraft has the word “Tetlin” painted on the top of its tail. The name is an homage to the Interior Alaska village, one of several selected to honor longstanding bonds between military aviators and Alaska Native communities, according to photographs of a dedication ceremony posted by the Alaska National Guard last summer.

The 168th Wing currently has 12 Stratotankers attached to the unit. That number bumped up in April after a long campaign by Alaska Republican U.S. Sen. Dan Sullivan to allocate more tankers to the state’s portfolio given its vast geography and high number of advanced fighter jets.
