Eye Tooth Tavern & Eatery: The long-awaited third Tooth restaurant opened its doors on Thursday.
A line of 75 or so people stretched outside just before the opening, said Rod Hancock, a founder of the company.
“We feel blessed and fortunate that people are excited to want to come and see what our new endeavor is,” he said.
The Eye Tooth is named after a climbing area in the Alaska Range like its predecessors, the original Moose’s Tooth Pub and Pizzeria and the Bear Tooth Theatrepub and Grill. It’s the only Tooth restaurant located in South Anchorage, at 8330 King St.
The new location will still focus on pizza, but with alternative varieties, said Hancock, a climber and self-described pizza lover.
It will be “its own unique collection of food, decor and concepts,” he said.
For now the Eye Tooth is starting with limited hours and a limited menu that includes many of the well-known pizzas served at the Moose’s Tooth, he said. But the menu will grow in the future, with new dishes released almost weekly, he said.
“We’ll be doing Detroit pizzas, tavern pizzas, Neapolitan pizzas, as well as the classic Moose’s Tooth pies,” he said. “So we’ve introduced some of those, but not all. There’s a lot more, culinarily, that we’re excited to do as we get situated and going.”
Already, the Eye Tooth is offering tavern pizzas with crispy, house-made sourdough crust, such as the Cup n’ Curl pepperoni with marinara and multiple cheeses. There’s also the Backcountry with goat cheese and other cheeses, yellow squash, mushrooms, red peppers and other ingredients. The New Haven includes sopressata, hot honey, cheeses, peppadew peppers and chives.
Chefs will also be able to make limited-batch dishes in a special “kitchen within our kitchen,” including seafood items and other plates, Hancock said.
The menu also includes hamburgers, sandwiches, fries and chicken wings, plus beers on tap, cocktails and a liquor menu that’s more whiskey-based than the other Tooth diners, he said.
The bar area features about 90 seats for dining or drinking, with a small stage for live music. Large glass doors open onto an outdoor beer garden.
A huge, gas-fed fire pit on the patio is made from the old the bull wheel from the former Chair 1 ski lift at the Alyeska Resort in Girdwood, he said.
A separate dining area, still being completed, will have an outdoor eating area.
The company purchased the building four years ago. Hancock initially hoped for a quick opening.
But the pandemic slowed plans. Hurdles included supply-chain issues, adding delays and cost.
“Doors were taking nine months to arrive, and then they’d come and be wrong,” he said. “There was also a fair amount of inflation in building materials. And so all the quotes were changing, and so we were re-crunching numbers and making sure that the project still penciled and made sense.”
The pandemic-era labor shortage also added serious concerns, he said. But that’s largely been alleviated. The Eye Tooth has hired around 50 people so far. That number could exceed 150 as the operation expands, he said.
The tavern is currently open 4-10 p.m. from Thursday to Saturday. Those hours will grow steadily starting soon, he said. The Eye Tooth should be fully operating by summer, he said.

Gogi Korean BBQ: Helena Yun ran a hairdressing salon in the Dimond Center for decades.
But she recently started her first restaurant, to share the social experience of eating traditional Korean food around a table grill.
“I always liked to cook and share with friends and that is my nature in my life,” Yun said. “And we (were) missing something like this restaurant in Alaska. So one day I decided this is going to be good for the community.”
At Gogi Korean BBQ, guests or staff can grill high-quality meats such as wagyu ribeye, prime beef kalbi, marinated pork short ribs, bulgogi or fire meat. Sprawling combo plates come with several shareable appetizers, such as soybean stew, steamed egg casserole, and banchan, or side dish, with its array of items like kimchi, caramelized potatoes, pickled daikon radish and green onion salad.
One unique feature at Gogi are overhead table lamps with vents that draw smoke upward through the food, adding to the flavor, Yun said. Wet- and dry-aging fridges also tenderize and flavor the meat.
Launching the restaurant took time, she said. “Every corner I touched with my soul,” she said.
Yun refused to open until she found the best meat through suppliers, she said. She designed every aspect of Gogi herself, down to the clean, black-and-white decor. Tables come with call buttons to summon staff, and “Korean 101″ sheets with expressions, like “annyeonghasaeyo” for “hello.”
Yun grew up in Korea, but moved to Alaska as a young woman close to four decades ago.
People say she’s “crazy” for opening a restaurant at an age when many are thinking about retirement, she said.
“But I always wanted to see this kind of restaurant in Anchorage,” she said one day last week, as customers began flowing in for dinner.
Gogi is located at 7780 Old Seward Highway. It’s open 11 a.m. to 10 p.m. on weekdays and on weekends, 11-11.
Get Scent Studio: Chester Mainot starting making candles as a pandemic hobby and selling them at markets.
Online sales soared after a friend with a social media following pitched his products on YouTube.
Late last year he opened Get Scent studio in Midtown Anchorage. And this month he went all in, quitting his job as a GCI network engineer for full-time entrepreneurship.
“It’s terrifying,” he said. “But I’m excited about being my own boss and doing what I love to do.”
Get Scent is located at 5121 Arctic Blvd., unit F, just down from Alaskan Burger & Brew.
It’s part gift shop and part studio, with classes for candle-making and succulent gardening. There’s also jewelry crafting with an Alaska Native artist who works with natural items like porcupine quills, sweetgrass and moose antlers.
Mainot’s candles are made with natural ingredients like soy wax. Scents can be traditional, like vanilla or lavender. The Alaskan collection includes wildberry, forget-me-not, and mountain trail, with forest fragrances like pine.
Another line focuses on the Philippines where Mainot grew up before moving to Alaska with his parents at age 20.
The Sampaguita, named for the Philippines’ national flower, reminds him of the floral smells drifting from his family garden at sunset. Halo-Halo, translated to mix-mix, smells like the dessert of the same name, made with shaved ice, tropical fruit and other ingredients. Ube is named after the country’s purple yam.
“Its nostalgia to me, my Filipino collection,” Mainot said.
Get Scent also sells gifts like locally made jewelry, fragrant wax melts and sprays, and beard balm.
It’s open Thursday to Sunday, 11 a.m. to 7 p.m.

Alaska Airlines lounge: The Alaska-born airline expanded its lounge at the Ted Stevens Anchorage International Airport this month, following a short closure for construction.
The upgrade doubles seating to 140. It adds cozy chairs, modern charging stations and small computer tables.
More windows overlook the tarmac, brightening the room and expanding the view of taxiing planes beneath mountains.
There’s several new pieces of Indigenous artwork from across Alaska, too, curated by the Alaska Native Heritage Center. They come with QR codes to explain the work.
“Each one of the pieces represents one of the major cultural regions,” said Kelsey Ciugun Wallace, a vice president at the heritage center, during a recent tour of the lounge. “The diversity is important because a lot of people mistakenly think about Alaska Native peoples as a monolith.”
The lounge hadn’t been revamped in years, said Marilyn Romano, vice president of the Alaska region for the airline.
Access is available through a membership or day pass. It offers a buffet of locally made, seasonal foods, hand-crafted espresso drinks using Kaladi Brothers beans, as well as wines, craft brews, cocktails and mocktails. It’s open daily almost around the clock, from 5 a.m. until 1 a.m.
The changes are part the airlines’ $60 million plan to improve terminals and other facilities around the state, including in communities such as Bethel and Kodiak. The lounge is the most visible of the upgrades in Alaska so far, Romano said.
The lounge was the company’s first to open in 1979. Up to 1,000 travelers use it daily. It’s the airline’s third-busiest lounge of nine — behind two in Seattle.

Moose A’La Mode: The cafe and sandwich shop closed in downtown Anchorage in December, after about two decades in business, said co-owner Brandi Rathbun.
She and her husband, Marty, purchased it during the pandemic. But a thinned-out downtown due to remote working, and struggles dealing with the homeless population, were factors in the closure, Brandi Rathbun said.
The couple still operates their Tiki Pete’s food trailers serving hot dogs, hamburgers and other fare. One will serve food at the the Last Frontier Pond Hockey Classic in Big Lake. The Feb. 21-23 event raises funds for the Scotty Gomez Foundation.
They also provide all the food concessions at the Sullivan Arena after it began doing public events last years, after its service as a low-barrier homeless shelter for much of the pandemic. That includes the baked potato bar, Pete’s Penalty Box with fare like chili dogs and mac n’ cheese dogs, and the Center Ice and Glacier grill with the Bobster burger with bacon and fried egg and the BrockStar burger with jalapenos and bacon.

Walgreens: The Walgreens store in northeast Anchorage at 7600 DeBarr Rd. closed in December, reducing the chain’s pharmacies in Alaska, among other services.
The retailer continues to operate eight stores in Alaska — six in Anchorage and one each in Wasilla and Eagle River, according to the company.
• • •
Party City: The party and costume supply store is closing its sole Alaska location on Feb. 26, a store representative said.
The national retailer announced in December it was shutting down. It has blamed competition from e-commerce and brick-and-mortar rivals, as well as inflation that forced its costs higher and slowed business.
The store is located in the Glenn Square in Northeast Anchorage, 3090 Mountain View Drive, No. 120.
• • •
Joann: The crafts retailer is closing two stores in Alaska, but it isn’t leaving the state entirely.
The chain’s lone location in Anchorage will close, at 3801 Old Seward Highway. The store in Juneau will also close, according to a recent closure list. No date has been announced yet, an Anchorage employee said Friday.
Joann stores in Fairbanks, Soldotna and Wasilla were not listed for closure.
The shutdowns stem from a bankruptcy restructuring plan, the result of competition from e-commerce and rivals like Walmart.
Joann recently listed 533 stores for closure across nearly all U.S. states. It operates more than 800 stores.

Norwegian filmmakers’ documentary spotlights homelessness in Anchorage, aims for Alaska screening
ANCHORAGE, Alaska (KTUU) – Two Norwegian filmmakers say their debut documentary, Anchorage Welcomes You, is meant to put viewers face-to-face with people living on Anchorage streets — not to prescribe a political fix, but to “describe the situation” and the human stakes behind a crisis visible across the city.
“I think the core story is to shine a light on the prevalence of the problem that is in Anchorage when it comes to drug abuse and homelessness,” said director/cinematographer Peter Gupta. “But it’s also to show how people are … capable of taking a wrong turn in life and coming back from it.”
The documentary was shot over multiple trips to Anchorage spanning roughly two years, beginning with a summer 2022 visit, followed by a winter 2024 return and a completion last fall.
Gupta, along with editor/screenwriter Rasmus Aarskog Sætersdal, said the project first grew out of Gupta’s canoe trip down the Yukon River, where he said he saw “communities ravaged by drugs and alcohol.”
“I canoed the whole length of the Yukon in 2017,” Gupta said. “And I saw what was going on in all the villages. And I wanted to go back and make a film at some point.”
Gupta said he met Anchorage resident Erinn Leann — a central figure in the film — at the end of that trip and told her then he planned to return to Alaska to make a documentary.
A title drawn from a sign — and the ‘duality’ beneath it
The film’s title comes from the weathered “Anchorage Welcomes You” sign seen by commuters entering the city — and, the filmmakers said, from what they described as the contrast between Anchorage’s image and the encampments they saw nearby.
“It was interesting when we were there the first year and we saw this Anchorage welcomes sign falling apart and a whole … camp growing up beneath it,” Sætersdal said. “And it was just this … you can say duality of presentation for the city.”
Gupta said the pair debated keeping the name, but after multiple test screenings they found Alaskans preferred the working title.
“We’ve had ambivalent feelings about the title of the film because it’s kind of tongue in cheek,” Gupta said. “We didn’t want to keep it at some point, but the people from Anchorage really wanted to keep it.”
Building trust — and setting rules
Much of the film unfolds in intimate, up-close moments that are hard to capture in traditional daily news reporting.
Sætersdal said filming required clear rules and consent. He said the filmmakers spent time walking the same routes and meeting the same people repeatedly. Gupta added that trust was foundational.
“I think it’s so important, that respect for whoever is participating, that’s a prerequisite for bringing them into the project,” he said.
Anchorage through outsiders’ eyes
Asked what makes homelessness in Anchorage distinct, Gupta said his travels shaped his perspective. Gupta described what he called “social fragmentation” and “hopelessness” — a situation he said can be more than just a lack of material resources.
“I’ve been around the world,” he said. “And the poverty in the United States is different.
“When you go to the United States, there’s a social fragmentation in a way that is quite unique. And I think there is a hopelessness and a different character to it … it’s not only a material problem. It is also a social problem.”
Sætersdal added Alaska’s identity as a frontier draws people seeking escape.
“Alaska still has this mythical place in imagination as the last frontier,” he said. “You see also people coming from all over the country … coming to Alaska in escapism of something. And then there’s nowhere else to go.”
‘Not to tell the people of Anchorage what to do’
Gupta and Sætersdal said they hope the documentary sparks conversations without presenting a single prescribed solution.
“What we’re trying to do with this film is not to tell the people of Anchorage what to do about homelessness,” Gupta said. “It’s about describing what’s happening and sparking a conversation.
“We hope that we can kind of make the homeless appear as resourceful and also capable of changing. But it’s not down to us what to do with it.”
Returning to Anchorage — and trying to bring the film home
Now, the two say the hope is to screen it in Alaska — and eventually get broader U.S. distribution. They said navigating distribution has been its own grind, but Sætersdal added that Alaska continues to pull at them creatively.
“Alaska really is a place that it sticks to you,” Sætersdal said. “You can’t unsee it once you’ve been there and you can’t like brush it off. It becomes a part of you.”

Alaska already has glaciers, whales, old gold-rush towns, wild seafood, and mountains. But Princess Cruises is taking the year by storm with something bigger than a standard summer schedule. The line is sending eight ships to Alaska, adding new North-to-Alaska programming, and giving travelers more ways to turn their trip into a full land-and-sea adventure.
Princess Is Going Bigger Than Ever

The 2026 Alaska season gives Princess its largest presence in the region to date, with eight ships, 180 departures, and visits to 19 destinations. Travelers are not boxed into a narrow route or one small batch of dates. The ship lineup includes Star Princess, Coral Princess, Royal Princess, Ruby Princess, Grand Princess, Emerald Princess, Discovery Princess, and Island Princess. For anyone comparing Alaska cruise options, that much capacity means more itinerary choices.
Star Princess Gives The Season A New Headliner

Star Princess is the newest ship in the Princess fleet. This matters because Alaska cruising can easily feel like a trade-off between destination and ship experience. Princess is putting one of its newest vessels into one of its most important regions. Star Princess also hosts the new Après Sea experience inside The Dome, a high-positioned venue designed around big views.
Glacier Days Get The Full Main-Event Treatment

Glacier viewing has always been one of Alaska cruising’s biggest draws, but Princess is giving it extra structure through “The Glacier Experience: A Signature Princess Day.” On select Glacier Bay sailings, guests get close-up glacier views, live narration, and Park Ranger commentary from the bridge and open decks. There are also theater presentations and Junior and Teen Ranger programming. VIP viewing areas and bowfront access add another layer for guests who want the best possible look at the ice.
The Trip Can Extend Deep Into Alaska By Land

Princess has long built part of its reputation around cruisetours that combine time at sea with inland travel. A seven-night sailing can deliver a strong Alaska trip in itself. However, inland travel opens the door to scenic train journeys, Princess Wilderness Lodges, and routes to places such as Denali, Kenai, and the Mt. McKinley lodge area. The 2026 season continues to lean into sea-and-land travel.
North To Alaska Makes The Ship Feel Local

Princess first introduced its North to Alaska program in 2015, and in 2026, every Princess ship sailing in Alaska will carry the new programming. The whole idea is to bring local culture, food, personalities, and storytelling on board so guests learn something about Alaska between ports. This includes Native Alaskan speakers, naturalists, enrichment presenters, and destination-focused events that connect the trip to the place outside the ship. Names in the speaker series include Tlingit voices, Alaska Native educators, writers, and photographers.
Alaska Seafood Gets A Bigger Seat At The Table

Princess is leaning into Alaska’s food identity with “A Taste of The Great Land.” The 2026 specialty restaurant offerings feature sustainably sourced, wild-caught Alaskan seafood created with regional suppliers. Crown Grill offers dishes such as Wild King Salmon, Alaskan Jumbo Lump Crab Cake, and Jumbo Lump Crab paired with Butter-Broiled Lobster Tail. Sabatini’s Italian Trattoria also brings Alaskan fish into an Italian-style setting.
The Entertainment Has Alaska In Its Bones

This season also features “Candlelight Concert Series: Fire & Ice,” with Alaska singer-songwriters performing in a candlelit setting twice per voyage. This gives the onboard entertainment a stronger sense of place than a generic music night. Returning favorites add a livelier side, including Great Alaskan Lumberjack Show elements with axe-throwing recruits, trivia, and timber-sports storytelling tied to Ketchikan. Select sailings also feature Deadliest Catch captains and crew members sharing Bering Sea crab-fishing stories. The lineup draws from Alaska’s labor, music, weather, and folklore.
Families Get More Than A Pretty View

Younger travelers are getting special attention, not a watered-down version of the adult trip. Glacier Bay Junior Rangers let kids complete activity books, attend presentations, and earn a badge and certificate through a partnership with the National Park Service. Gold Rush Adventures pulls families into a shipwide Klondike-style search, while Great Alaskan Expedition offers youth and teens a three-hour team-based experience across land, sea, and air. As puppies in the Piazza also return on ships visiting Skagway, guests get to see Alaskan Huskies and sled-dog culture.
Après Sea Gives Alaska A Stylish Cooldown

After a long day outside, Princess is adding a dedicated wind-down ritual through Après Sea. The setup is inspired by après-ski culture. Guests can expect warm drinks, happy hour, and panoramic views after they return from exploring. On Star Princess, the experience is in The Dome, and it provides a strong visual setting at the top of the ship. A relaxed lounge concept gives the evening its own personality, and guests don’t have to jump straight from adventure into dinner.
MedallionClass Keeps The Whole Trip Moving Smoothly

Alaska days can get busy fast, with early excursions, glacier viewing, dinner plans, family meetups, and plenty of time spent moving around the ship. The Princess Medallion Class setup helps cut down on small hassles. The wearable Medallion supports contactless boarding, keyless stateroom entry, onboard ordering, contactless payment, ship navigation, and locating travel companions through the app. When the day already includes ports, wildlife, ice, and dinner reservations, fewer friction points onboard can make a real difference.
Rachel Feltman: Happy Monday, listeners! For Scientific American’s Science Quickly, I’m Rachel Feltman. Let’s kick off the week with a quick roundup of some science news you may have missed.
First, you may have seen some headlines last week about an outbreak of hantavirus on a cruise ship. Here to tell us more about what happened is Tanya Lewis, SciAm’s senior desk editor for health and medicine.
Tanya, thanks so much for coming on to walk us through this.
On supporting science journalism

Tanya Lewis: Yeah, no, thanks so much for having me.
Feltman: Why are we talking about hantavirus and this cruise ship? What happened?
Lewis: Just to catch people up, this outbreak was first noticed about a week ago on a ship called the MV Hondius, which was a cruise ship departing from South America, Argentina. And the people that were sickened and unfortunately passed away, two of those individuals were a married couple who had been traveling—it was a Dutch couple—we think were infected in Argentina and then boarded the ship. And then subsequently, multiple other people have been infected. As of May 7 the number of people on this cruise ship who had been infected with hantavirus was eight people. So that probably could still change.
But you might not have heard of hantavirus before, but it is a virus family that people have been sickened with before, and it’s generally spread by rodents, like rats or mice. And this commonly happens in places where people are exposed to the feces of these animals.
And it causes pretty severe disease. It can cause anything from respiratory distress and fluid in the lungs to some forms of it can be more of, like, a hemorrhagic fever, kind of like Ebola. But the kind that we’re seeing on this cruise ship is more the respiratory kind.
But yeah, this is a virus that, while it is fairly rare to be infected with it, it’s quite lethal. The estimates of its lethality vary, but anywhere from, like, 30 percent to even 50 percent of people infected have died of it.
Feltman: Right, well, and like you said, it, it’s usually spread through rodent feces. But unfortunately, the specific virus we’re talking about, with regard to this cruise ship, is one of the rare instances where it is technically possible to spread from human to human. Can you tell us a little bit more about that?
Lewis: Basically, these individuals on the ship were thought to be infected by human-to-human transmission. At least, that’s the working hypothesis right now. And the reason has to do with the exposure routes.
As I mentioned two of the people were a married couple, so we’re talking about, like, very close contact. This is not something like SARS-CoV-2, the virus that causes COVID, where it’s, like, in the air and wafting around for hours or something. This is something that you would probably need to be, like, breathing very closely, in the same space. And of course, cruise ships are, like, kind of the perfect petri dish for that.
Feltman: Yeah.
So I think there are two things to talk about. There’s, one, why experts are not immediately super concerned about pandemic potential from this specific thing, but also why it is reasonable that I think so many of us, when seeing this news, went, “Uh-oh. We’re—this is a reminder of public-health paradigms I do not wanna be reminded of.”
So let’s start with the good news: Why are experts not freaking out about this?
Lewis: Yeah, so we have to remember that this is a virus that is very different than a lot of the pathogens that have caused respiratory pandemics in the past. In order for a pathogen to be a major pandemic concern, it needs to be very transmissible, and that is something that we have not yet seen with this hantavirus.
I should say, this particular strain is the only strain that has been shown to transmit human to human; it’s called the Andes strain. Most hantaviruses are not thought to spread that way. So the good news is, it’s kind of rare. The bad news, maybe, is that it does appear to have spread, at least, you know, in a limited way, between people.
But yeah, in terms of why experts are not, like, immediately concerned that this will spark a larger epidemic, I think the reason is just that this type of virus and the way it spreads is not conducive, as far as we know, to that type of outbreak. And it’s also happening in a very contained space, so although there have been reports that several of the people on board the ship have disembarked and we are still following that closely, at this point there is no indication of wider community spread, which is what we call it when people are getting infected who have not had direct exposure to the infected individuals.
Feltman: Is there any concern that the time that this virus spent, you know, in such a perfect petri dish may have given it the opportunity to mutate and be better at jumping from person to person?
Lewis: I think what virologists would tell you is, like, the more opportunities a virus has to jump between people, the higher the risk of it developing, like, a concerning mutation that makes it more transmissible.
That said, we’re still talking about a relatively small number of individuals. I mean, eight people sounds like a lot, but, you know, when you’re talking about this being very close quarters on a ship, this is not like, oh, you’re walking into a giant city like New York City and infecting everyone around you or something. So I think that is a little bit reassuring, perhaps, at this point.
But that said, we’ve been humbled before, and I think if there’s one lesson we can take from the COVID pandemic, it’s that we shouldn’t panic, but we should definitely pay attention. And at least scientists wanna know and learn more about this virus and understand it better.
Feltman: I think a lot of people are getting a little freaked out by this news. [Laughs.]
Lewis: Yeah, and I mean, I would be the first to say, like, something like this you hear about, it’s, like, instantly puts you back in that fearful space of 2020. And of course, there was the famous cruise ship, the Diamond Princess, where some of the early COVID cases happened. So that is always concerning.
On the other hand, you know, we have to sort of put it in perspective and remember this is a rare virus and it is something that people have been infected with in the past, so it’s not a completely new virus, unlike SARS-CoV-2, which we had never seen before. So we do have some idea of how this virus works, and while we don’t have any specific treatments for it, we do at least have experts who study it. So that should hopefully give some reassurance that, like, this is not a complete unknown. We are not starting from square one.
Feltman: Thanks for that, Tanya.
Now, listeners, keep in mind we had this conversation on Thursday, May 7. But you can always go to ScientificAmerican.com for more up-to-date science news.
Now for new research on micro- and nanoplastics—but this isn’t the health story you might be expecting. According to a study published last Monday in Nature Climate Change, these tiny bits of broken-down plastic could be contributing to our planet’s warming temperatures.
For starters, just in case you are blissfully unaware: yes, there are, unfortunately, microplastics in the sky. According to a study published in 2021, some of these particles swirl up into the air from the road, where tires and brakes frequently shed small pieces of plastic.
Now, the idea of microplastics permeating the air and even seeding clouds into existence is creepy enough, in my opinion. But this new study suggests they can also have a warming effect on the atmosphere.
Here’s how that would work: if you’ve ever spent time on a patch of blacktop on a sunny summer day, you know that black material absorbs heat. Conversely, white material reflects heat. The same thing happens when you scatter bits of dark and light plastic into the atmosphere, which is what humanity has inadvertently done quite a bit over the past few decades.
Unfortunately, according to this new study, any cooling effects we might get from light microplastics are probably vastly outweighed by the warming effects of dark microplastics. While the estimated effect is a small percentage of the warming fueled by soot from coal power plants, the results are still worrying.
As Jackie Flynn Mogenson reported for SciAm last week, we don’t actually know the concentration of micro- and nanoplastics currently in our atmosphere. But the authors of the new study argue that global climate assessments should do more to factor in these tiny plastic bits. And their findings serve as a great reminder that when we talk about the downsides of plastic, we should recognize that there may be impacts far less concrete and obvious than creating growing piles of trash in landfills.
Now I’ll turn the mic over briefly to SciAm’s chief newsletter editor, Andrea Gawrylewski. She’s gonna tell us about the science behind a tsunami that caught Alaska by surprise.
Andrea Gawrylewski: Thanks, Rachel.
Last summer, in August, a small cruise boat called the David B spent the night in an inlet about 50 miles from Juneau, Alaska. They were supposed to be at anchor nearer to Juneau in this beautiful fjord called Tracy Arm, but bad weather had forced them to pick another place to stay. And it turns out that detour may have saved their lives.
In the morning, from where they were anchored, the boat’s owners noticed seawater rolling over the nearby [sandbar] and shoreline. It was weird because the tide was supposed to be out at that time, and they had no idea why the water was so high.
When scientists heard about the strange sea-level rise, they began examining seismic data, they looked at aerial footage and satellite images, and determined that a massive landslide had occurred at the top of the Tracy Arm fjord.
So what had happened?
The South Sawyer Glacier at the top of Tracy Arm has been steadily shrinking and retreating for the last 25 years. In the spring and summer of last year the ice retreated inland several hundred feet, exposing so much bare rock that it ultimately caused a landslide.
That big slide hit the water and sent a tsunami racing through the fjord—like, so much water that the tsunami surged more than 1,500 feet up the sides of the fjord and sloshed back and forth, like in a bathtub.
That event also produced a seismic signal equivalent to a magnitude 5.4 earthquake. Scientists found smaller seismic events in the data that had occurred at least 24 hours before the big one, and they were increasing exponentially in intensity in the six hours before the landslide.
So now the question is: Could these early seismic signals be used as a warning system? One scientist at the Alaska Earthquake Center has been testing a landslide detection algorithm, and so far it’s detected 35 landslides in near real time. Sending out warnings within three to four minutes of big events could make all the difference to people who live in the area, so scientists are working to improve tools like these.
