Russia’s War Economy Is Heading To Recession: It Probably Won’t Slow Down The War – Analysis

Red Square, Moscow, Russia.

(RFE/RL) — At Russia’s annual marquee event for business investment, a Kremlin-funded bubbly celebration of promise and opportunity, the country’s top economic minister poured cold war on the party.

“According to the numbers, yes, we’ve got a cooling down now,” Maksim Reshetnikov said at the St. Petersburg International Economic Forum. “Based on current business sentiment, it seems to me we are on the brink of transitioning into recession.”

If that wasn’t enough of a damper, the head of the Russian Central Bank seconded the downbeat sentiment.

“We have been growing for two years at a fairly high rate due to the fact that free labor resources were used,” Elvira Nabiullina said during the same panel discussion on June 19. “But we need to understand that many of these resources have really been exhausted. We need to think about a new model for growth.”

And there was also this from German Gref, the head of the state-owned banking giant Sberbank, on the sidelines of the forum: “We are colliding with a large number of problems, which today we can call a perfect storm.”


For more than 40 months now, since the start of the all-out invasion of Ukraine, Russia’s economy has been on a war footing, growing at a robust — at times torrid — rate, and showing resilience — unexpected to many Western experts — in the face of punishing sanctions.

The Kremlin has retooled the economy to power its war, pouring money into defense industries to churn out guns, tanks, drones, and uniforms. It’s poured money into wages for defense industry workers and paid soldiers sky-high salaries and benefits to entice them to fight in Ukraine.

That’s transformed local economies in many of the country’s poorer, remote regions, and also bought support for the conflict.

But high wages have fueled inflation, and Nabiullina hiked the key interest rate to 21 percent in October to try and tamp it down. Despite public complaints from the country’s industrial lobby, she has held firm, committed to slowing inflation and downshifting the economy.

It’s working, and now Russia is facing the first significant economic slowdown since the start of the full-scale war.

“I think a lot of indicators point to growth stopping, or close to it,” said Iikka Korhonen, head of research at the Bank of Finland’s Institute for Emerging Economies. “Manufacturing is still growing, but most other things are not.”

“For two years [the] Russian economy was overheated and growing at a pace way above its normal growth rate,” said Alexander Kolyandr, an economics expert with the Center for European Policy Analysis in Washington. “So what’s happening now is the economy returns to where it should be. For the moment it stands as a correction, coming back to the long-term growth rate.”

“The main challenge for the government at this point is to make this a soft landing, rather than a complete collapse,” he said.

What Comes Next?

Russia’s gross domestic product grew by 1.4 percent in the first three months of the year, compared with the same period in 2024, according to government statistics. In the last six months of 2024, however, the economy was humming along — with average growth of around 4.4 percent.

Official estimates now forecast GDP growth at around 2 percent in 2025. The International Monetary Fund predicts even lower growth — 1.5 percent.

The unemployment rate stands at a historic low of around 2.3 percent, underscoring how distorted the labor market has become as men are drawn away from civilian jobs to fight in Ukraine.

Faced with inflation running at over 10 percent in the first half of 2025, Nabiullina has warned repeatedly about an “overheated economy.” In early June, she engineered a small rate cut, to 20 percent, which experts called largely symbolic.

But the impact of the high interest rate is showing up in official statistics,according to data and forecasts from the Center for Macroeconomic Analysis and Short-Term Forecasting, a government-linked research group.

For some in the Kremlin, a soft landing would be a welcome correction to the two torrid previous years. The danger is if it becomes a hard landing.

“By keeping the key rate very high, despite the state continuously pumping money into the economy, they have been able to achieve economic slowdown,” said Maria Snegovaya, a senior fellow in the Russia program at the Washington-based Center for Strategic and International Studies.

“It’s unclear how sustainable the situation is for the Kremlin if the economy is actually declining. It’s not something that they want either,” she said during an online discussion on June 17. “In general, the Russian macroeconomic team seems to be quite concerned.”

What this means politically is harder to predict.

So far, President Vladimir Putin has given Nabiullina and other top economic officials his blessing for their handling of the economy.

A day after the panel discussion at the St. Petersburg forum, Putin weighed in himself, with a cautionary note in a speech at the business forum:

“Some specialists, experts, point to the risks of stagnation and even recession,” he said. “Of course, this should not be allowed under any circumstances.”

“Our most important task this year is to transition the economy to balanced growth,” Putin said.

With other parts of the economy crimped by sanctions, Kremlin coffers are even more heavily dependent on oil and gas revenues than they have been in the past. But oil prices have fallen since the beginning of the year, and the Finance Ministry haslowered its forecast for oil-linked revenues for 2025.

“Unless we see a decline in oil prices, [or] some significant increase in sanctions enforcement, and an overall decline in civilian production, then I think there will be a soft landing,” Kolyandr said.

Balanced — or slower — growth will ripple through the economy, putting a brake on wage growth. It will also crimp household budgets at a time when Russians have been accustomed to fatter wallets, which could fuel discontent.

A growing number of companies and factories are also falling behind in wage and salary payments to workers, according to the newspaper Nezavisimaya Gazeta. And a growing number of regions have started cutting recruitment bonuses for new volunteer soldiers — a trend that reflects worsening economic conditions on a local level.

Still, Putin seems determined to push forward in the war — even faced with eyewatering casualty rates that are approaching 1 million men killed or wounded. The government plans on spending about 13.1 trillion rubles ($144 billion) on defense- and security-related expenditures in 2025. That’s 6.3 percent of its GDP, one of the highest levels since the Soviet era.

“Unfortunately, yes, this war will not stop for economic reasons, and Russia can continue to produce [weaponry] at the current level for quite a while,” Korhonen said. “The only economic factor that could really hamper Russia’s war effort is the price of oil.”

Azerbaijan arrested two Russian journalists on June 30 and ordered fresh autopsies on two Azerbaijani brothers killed by the Russian Federal Security Service (FSB) in Yekaterinburg, escalating diplomatic tensions with Moscow as both sides traded accusations over the killings that shocked Azerbaijan.

FSB forces killed the brothers and arrested nine others during violent raids on Azerbaijani homes in connection with a murder investigation in Yekaterinburg on June 27. The raids triggered a strong diplomatic response from Azerbaijan, after relations between Baku and Moscow were previously soured by the downing of an Azerbaijani AZAL aircraft by Russian air defences.

The bodies of brothers Ziyaddin and Husein Safarov arrived in Azerbaijan on June 30 and were handed over to relatives. The victims will undergo new medical examinations before burial in Agjabadi, according to the APA news agency.

Seyfaddin Huseynli, brother of the killed men and a prominent journalist, announced Azerbaijan would conduct independent medical examinations. "We are certain that Russia's fabricated autopsy report does not reflect the truth, so the bodies will undergo fresh medical examination in Azerbaijan, and it will become clear what really caused our brothers' deaths," he told reporters, according to APA.

Huseynli expressed gratitude for Azerbaijan's exposure of what he termed Russia's "intelligence network" in the country. "The exposure of Russia's spy network in Azerbaijan these days brought water to our family's heart. For all our compatriots, this was consolation. I thank the Azerbaijani state both on my own behalf and on behalf of people who suffered from Russia's merciless regime," he said.

Tit-for-tat arrests

Hours after the bodies' return, Azerbaijan's interior ministry conducted operations at Sputnik Azerbaijan's Baku office, arresting executive director Igor Kartavykh and chief editor Yevgeny Belousov. The Russian state media outlet's operations were suspended in February 2025, though staff continued working illegally, according to a statement from the ministry.

The interior ministry said investigations began based on operational intelligence that the agency continued activities through illegal financing despite accreditation suspension. "On June 30, search operations were conducted at the branch office, and there are detainees," the ministry confirmed to APA.

Russia immediately summoned Azerbaijan's ambassador Rahman Mustafayev over what Moscow termed "unfriendly actions" and "illegal detention of Russian journalists". Foreign ministry spokeswoman Maria Zakharova expressed concern that Russian diplomats in Baku could not contact the journalists for several hours and were denied consular access. 

"The detainees are Russian citizens of Azerbaijani origin. They were arrested as part of an investigation into serious crimes committed in previous years. The investigation is ongoing," she said, according to JAMnews. She confirmed that Russia's chargé d'affaires provided clarification to the Azerbaijani foreign ministry on June 28.

Unprecedented media condemnation

Azerbaijani state media’s has launched its harshest ever criticism of Russian President Vladimir Putin personally. In an evening news broadcast on June 29, state channel AzTV described Russia as a "prison of nations”, according to JAMnews.

"What's wrong, Mr. Putin? Are you so disturbed by the fact that Azerbaijan has become a strong regional power, has returned its territories for the first time in 200 years, and defended its national interests?" the anchor declared, referring to Azerbaijan’s recovery of Nagorno Karabakh after decades under Armenian control. 

"You are used to ruling over people forcibly absorbed into your empire. In tsarist and Soviet times, Russians were treated as a superior race," he said. "This is a systematic policy directed by Vladimir Putin," the AzTV presenter stated, drawing parallels with Russian actions in Ukraine.

Later broadcasts compared current Russian policy to 1930s Germany, whilst state agency Azertag published commentary directly accusing Putin of systematic persecution. 

European Union ambassador to Azerbaijan Peter Michalko became the first senior Western diplomat to condemn the Yekaterinburg killings. "I am deeply concerned by reports of violence, torture and inhuman treatment by Russian security forces against ethnic Azerbaijanis, even resulting in deaths. My thoughts are with the victims and their families," he wrote on social media.

Opposition leader Ali Karimli of the Azerbaijani Popular Front Party delivered one of the strongest reactions to the Yekaterinburg killings. Speaking to JAMnews, he argued the incident was directly ordered by Putin rather than a law enforcement initiative. "Moscow wants to see Azerbaijan as a fully submissive vassal and seems confident it has already achieved that," Karimli stated. He attributed this confidence to "Azerbaijan's internal weaknesses: corruption, economic monopolies, the collapse of democratic institutions, and the concentration of political power in the hands of one man."

Karimli issued a direct challenge to Azerbaijan's leadership: "Either submit to the demands of the Russian Empire and effectively accept the role of its governor, or open up to the people and the international community, and show political will to defend independence and citizens' rights," he said.

Political analyst Shahinoglu connected the incident to Azerbaijan's February closure of the Russian House cultural centre in Baku and restrictions on Sputnik's activities. This suggests the Yekaterinburg killings represent retaliation for Azerbaijan's efforts to limit Russian soft power influence.

Historian Altay Goyushov told JAMnews the incident highlights structural problems forcing Azerbaijanis to seek work in Russia. "People go there not for prosperity, but simply to have the opportunity to work freely," he argued, noting that Azerbaijan lacks sufficient economic freedoms for its own citizens. "For comparison: I recently learned that the Azerbaijani government lifted visa requirements for Chinese citizens long ago, but China still hasn't lifted visas for Azerbaijanis. Why? Because they know Azerbaijanis are ready to accept anything and go anywhere, just to escape the problems in their own country," Goyushov said.

Sputnik Azerbaijan previously targeted Azerbaijani journalists working for AbzasMediaToplum TV and Meydan TV, accusing them of working for Western intelligence. Arrests of the journalists started after this targeted attack. Commenting on this, Goyushov told bne IntelliNews that “[Azerbaijani President Ilham] Aliyev’s regime had just told them to write [the article], so they did." Goyushov believes that Aliyev used Sputnik for his own interests. "It’s their old habit. Finding a scapegoat never causes any difficulty — there’s always some housing office manager they can throw under the bus," he concluded.

Russian criminal allegations

Russian authorities provided their first detailed justification for the FSB operation, claiming the Safarov brothers led an ethnic criminal organisation active since the late 1990s. TASS quoted law enforcement sources alleging the group engaged in "illegal activities selling drugs, alcoholic and tobacco products, gambling, supervising prostitution and distributing pornographic materials."

The sources claimed one victim was an entrepreneur who refused to pay protection money and was murdered by the group. They also suggested possible links to mass alcohol poisoning in Yekaterinburg in 2021 and ownership of kiosks selling counterfeit goods.

Russia's Investigative Committee has opened criminal cases under multiple articles, including group murder, contract killing and attempted contract murder relating to incidents in 2001, 2010 and 2011. Six suspects were charged, with three Safarov family members receiving 22-day detention orders.

The timing and nature of Russia's criminal allegations raise significant credibility concerns. No charges were filed against the family during 24 years of alleged criminal activity, despite Russian authorities claiming detailed knowledge of their operations since the late 1990s.

The decision to conduct lethal raids rather than standard arrests for historical crimes appears disproportionate, particularly given torture allegations from defence lawyers. According to pro-government outlets in Azerbaijan, the operation's timing — immediately following Azerbaijan's demands for accountability over the AZAL aircraft downing — suggests political rather than criminal motivation.

Russian authorities have not explained why two suspects were killed rather than arrested, nor addressed allegations of torture and property theft during the raids. Defence lawyers report that the only evidence comprises confessions obtained under duress and testimony from unnamed witnesses.

Escalating diplomatic crisis

The journalists' arrests are Azerbaijan's most direct retaliation against Russian interests since independence. Unlike previous diplomatic protests, Baku has now demonstrated a willingness to target Russian state media operations and personnel.

This follows Azerbaijan's cancellation of cultural events and parliamentary cooperation, suggesting a coordinated strategy to impose costs on Russia across multiple sectors. The foreign ministry has yet to respond to Russia's diplomatic protest, indicating Baku intends to maintain pressure. 

The crisis occurs against the backdrop of the exposure of Russia's intelligence network in Azerbaijan, which Huseynli referenced as providing "consolation" to affected families. This suggests broader Azerbaijani counterintelligence operations targeting Russian influence networks. In May 2025, Ramid Namazov, head of the Azerbaijani parliamentary commission on hybrid threats, openly accused Russia of orchestrating the intrusion, citing digital fingerprints linked to Russian intelligence infrastructure.

Earlier in April 2025, Azerbaijani ruling party MP Azer Badamov, travelling as part of an official delegation to Astrakhan for commemorations of former Azerbaijani president Heydar Aliyev’s 102nd anniversary, was detained at Moscow’s Vnukovo Airport. Russian authorities informed him he was banned from entering the country. He was denied boarding for his internal connecting flight and returned to Baku without explanation. 

As of June 30, President Aliyev had issued no public statement on the FSB killings, despite his established personal alliance with Putin.

 

UPDATE: Thai prime minister suspended by court over leaked audio – Cambodia regards this as Thai internal issue

Thai Prime Minister Paetongtarn Shinawatra has been temporarily suspended from her duties following a decision by Thailand’s Constitutional Court to accept a petition submitted by a group of senators, according to a report by Prachatai English. The court’s ruling comes in the wake of a leaked audio recording allegedly featuring a private conversation between Paetongtarn and former Cambodian Prime Minister Hun Sen.

In the court session held on Tuesday, July 1, seven out of nine judges voted in favour of suspending the prime minister while the case is under investigation. Deputy Prime Minister Suriya Juangroongruangkit has been appointed as Acting Prime Minister in the interim.

The petition against Paetongtarn alleges that she has breached ministerial ethics. Her suspension also coincides with rising tensions over an unresolved border issue with Cambodia, which has led to temporary closures of certain border crossings and disruptions in the movement of people and goods. When questioned recently about the matter, Paetongtarn admitted feeling anxious, saying, “If you are asking if I am worried, I am.”

From the Cambodian side, the government has responded cautiously. Speaking to Kiripost, government spokesperson Pen Bona emphasised that the issue is an internal Thai affair. “This is not a matter involving Cambodia,” he said. “Cambodia respects the internal political processes of its neighbour.”

When asked whether the leadership change in Thailand could affect ongoing bilateral discussions, including those on border demarcation and trade, Pen Bona reaffirmed Cambodia’s stance on continuity and cooperation.

“Cambodia will continue to engage with Thailand regardless of political changes. We remain committed to maintaining constructive relations and resolving shared challenges through dialogue,” he added.

The Constitutional Court of Thailand has ruled 7-2 to suspend Paetongtarn Shinawatra from her duties as Prime Minister according to sources in the region.

The court has agreed to consider her impeachment over a  recent highly controversial audio clip of a phone call that emerged as part of a territorial spat with neighbouring Cambodia. 

In the recording, Paetongtarn is understood to have referred to Hun Sen - Cambodia’s former leader - in familial terms whilst also criticising a senior Thai military figure. The incident triggered widespread public backlash and eventually prompted a formal petition seeking her removal. That request is now under court review local sources including The Nation report.

The suspension sidelines Paetongtarn temporarily as she is given 15 days to respond to the allegations against her. In the meantime, Deputy Prime Minister Suriya and Minister of Transport, Jungrungruangkit has stepped in as acting prime minister.

Paetongtarn is now the third member of the influential Shinawatra political dynasty to be pushed out of office before completing a full term. The family has shaped Thai politics for more than 20 years but has repeatedly faced challenges from more conservative and military-aligned factions.

Her fragile ruling coalition, which only holds a narrow majority, has been further weakened by the recent withdrawal of a major right-wing partner.

Should the court opt to remove her, Paetongtarn would become the second prime minister from the Pheu Thai party to be ousted in under a year. Her predecessor, Srettha Thavisin, lost his position in August 2024 after he controversially appointed a cabinet minister who had previously served a prison sentence the BBC reports.

Paetongtarn, herself the daughter of former prime minister Thaksin Shinawatra, took office shortly afterwards. At 38, she is the youngest person to lead Thailand and to date only the second woman to do so, following her aunt Yingluck Shinawatra - who was also removed from office.

The current scandal adds to the headwinds facing Paetongtarn’s government as it struggles to boost a flagging economy. Public confidence in her leadership has dropped sharply, with approval ratings falling to just over 9% in recent days, compared with 31% as recently as March.

Paetongtarn has issued an apology for the remarks made in the leaked call, describing them as part of a diplomatic approach to ease tensions over recent border disputes. However, critics in Parliament, particularly among conservative MPs, accuse her of yielding to Cambodia and compromising national security.

El Salvador’s Bukele offers to ‘ship inmates to Paris’ following fashion week controversy

El Salvador’s Bukele offers to ‘ship inmates to Paris’ following fashion week controversy
Chavarria opened his Paris show with a tribute to immigrants and US citizens facing ICE detention and potential deportation to El Salvador, as the models walked the runway "dressed in baggy white tees and loose shorts."

El Salvador’s government has sharply criticised a Paris Fashion Week show by Mexican-American designer Willy Chavarría for featuring outfits resembling the prison-issue uniforms used in the country’s maximum-security Terrorism Confinement Centre (CECOT). AFP reported that the former Ralph Lauren designer staged models kneeling in white T-shirts and shorts, mirroring imagery associated with the mega-prison’s inmates.

According to Dazed, Chavarria opened his June 27 show with a tribute to immigrants and US citizens facing ICE detention and potential deportation to facilities in countries including El Salvador, as the shaved-headed models walked the runway "dressed in baggy white tees and loose shorts." The gesture comes as President Donald Trump intensifies his crackdown on illegal migration.

El Salvador's President Nayib Bukele quickly responded on social media, quipping that his government could “ship them all to Paris” if France authorised it—an assertion his press office later portrayed as a principled stand against “glorifying criminality.” Yet, the tone of the reaction underlines the government’s sensitivity to how its tough-on-gangs narrative is depicted abroad.

CECOT, a mega jail established in early 2023 under Bukele’s security initiatives, has capacity for 40,000 inmates but housed approximately 14,500 by mid-2024 and over 105,000 across the system by December 2023. Built as part of a broader strategy to reduce gang violence, the facility operates under a state of emergency first declared in March 2022. This legal framework permits arrests without warrants and has resulted in roughly 86,000 detentions—among them over 3,000 minors—according to rights groups and official sources.

Although homicides have declined significantly, numerous international observers, including Human Rights Watch, Amnesty International, the UN High Commissioner for Human Rights, and Human Rights First, have flagged patterns of arbitrary arrests, overcrowding, torture, and due-process violations.

Notably, CECOT also houses around 252 Venezuelan migrants deported under the Trump administration’s wartime Alien Enemies Act. These individuals were transferred to El Salvador without court hearings under a controversial bilateral agreement and are accused of gang affiliation, claims their lawyers dispute. Venezuela’s attorney-general has condemned their treatment as “human trafficking,” calling for their release. Reports describe substandard conditions: severe overcrowding, inadequate food, limited legal access, and instances of physical and psychological harm. 

Several Salvadoran police officers, speaking anonymously, have confirmed the existence of arrest quotas and fabricated cases aimed at meeting targets to boost profits, further raising questions over the rule of law. The Catholic Bishops of El Salvador have also warned that the country risks becoming an “international prison” if deportation policies continue


Social Probing: indirect surveys to better understand society



The project, coordinated by IMDEA Networks, proposes an innovative alternative to understanding public opinion with fewer resources and greater respect for privacy




 News Release 

IMDEA Networks Institute






How can we understand what a society thinks without relying on traditional surveys that require large samples and significant investment? The Social Probing project, now completed and coordinated by researcher Antonio Fernández Anta at IMDEA Networks, was carried out in collaboration with UC3M, UPM, and Universitat Jaume I to achieve precisely that: develop scalable, cost-effective, and privacy-preserving tools that allow for continuous societal monitoring. Their solution: indirect surveys.

This type of survey doesn’t ask people directly about their own opinions, but about those of their contacts: “How many of your contacts would vote for party X?” or “How many have shown symptoms of COVID-19?” Based on these responses, the team can estimate the actual behavior or situation of the broader population.

New uses for an underutilized technique

Although indirect surveys have existed for decades, their use has been limited. Social Probing, funded by the Ministry of Science, Innovation and Universities, has revived and expanded this methodology, applying it to diverse contexts such as COVID-19 tracking, voting intention estimation in various elections, and the distribution of domestic chores between men and women, in collaboration with the Women’s Institute.

“Thanks to this technique, we’ve been able to accurately estimate voting intentions in regional (such as Madrid or Valencia), national, and European elections. In fact, in the national elections in Madrid, our seat distribution estimate missed just one seat—using only 200 participants—compared to traditional surveys that rely on thousands,” Fernández Anta emphasizes.

More privacy, lower cost, greater honesty

Indirect surveys offer several advantages over traditional polls: they require smaller samples, which reduces costs, and they better preserve privacy. “Asking about the voting intention of a participant’s contacts is less intrusive than asking about their own,” explains Fernández Anta. This also increases the likelihood of receiving honest answers.

The team also identified key factors that influence result accuracy, such as the participant’s age, which can introduce hard-to-correct biases. To address this, they have begun stratifying samples by age groups.

Results and next steps

The project’s main outcomes include both the data collected and the tools developed to design, deploy, and analyze indirect surveys. This technological and methodological legacy will live on beyond the project: the team is currently working on a PhD thesis focused on robust methods for processing this kind of data, and on identifying which types of social networks are best suited for its application.
They are also exploring new application areas, such as raising awareness about water use in Spain, with new surveys already in development.

 

Fentanyl detection through packaging




PNAS Nexus





Fentanyl has killed hundreds of thousands of people globally since 2015. Detection of the drugs during interdiction is currently done through Raman spectroscopy or chemical strips—both of which require direct access to samples. Michael Malone and colleagues use a magnetic resonance technique to detect fentanyl hydrochloride inside sealed opaque containers and packages—an approach that could be used in airports, border crossings, post offices, and other contexts. Nuclear quadrupole resonance (NQR) spectroscopy sends a radio frequency pulse with a frequency corresponding to a transition energy of the target nucleus and, if the target nuclei are present, receives in return a detectable and chemically specific magnetic signature. For fentanyl, key target nuclei include the naturally abundant isotopes of nitrogen and chlorine. Effective NQR spectrometers can cost just a few thousand dollars and do not require superconducting magnets or extreme temperatures. There are some limitations: thick metallic wrapping could block detection, and the detector must be within several centimeters of the drugs. According to the authors, the technique could nevertheless help detect and divert large quantities of fentanyl.

 

New 3D glacier visualizations provide insights into a hotter Earth



Fine satellite monitoring offers novel way to track glacier melt, study finds



Ohio State University





COLUMBUS, Ohio – As glaciers retreat due to a rise in global temperatures, one study shows detailed 3D elevation models could drastically improve predictions about how they react to Earth’s warming climate.  

While only 10% of Earth is covered in glacial ice, these masses have far-reaching impacts on all the world’s ecosystems. Rapid melting can trigger natural disasters, and glaciers help to regulate the planet’s temperature and sea level and are sources of pristine fresh drinking water.

To better differentiate between seasonal ice loss and that caused by long-term climate trends, researchers studied the fluctuating heights of three glaciers: the La Perouse Glacier in North Americathe Viedma Glacier in South America and the Skamri Glacier located in Central Asia.

Their analysis revealed that between 2019 and 2023, the Viedma Glacier (Argentina) and the La Perouse Glacier (Alaska) experienced consistent thinning, but the Skamri Glacier (Pakistan)  had been stable enough to experience a small net gain of ice, said Rongjun Qin, co-author of the study and an associate professor of civil, environmental and geodetic engineering at The Ohio State University.

Measurements in this study were made using daily high-resolution images gathered by the PlanetScope satellite constellation, which researchers then used to create 3D reconstructions of how glacial ice flows evolved over time. By incorporating local and global climate data into these models to explore seasonal variations of glacier melt, the team essentially designed a way to monitor the behavior of glaciers across diverse regions.

“This is something that we’ve been thinking about for a long time, because existing glacier studies have such sparse seasonal observations since it’s difficult to get data out of remote areas,” said Qin, who is also a core faculty member of Ohio State’s Translational Data Analytics Institute. “What we wanted to do is to use medium-to-high resolution data to broaden those capabilities and improve the accuracy of the 3D models generated from that data.”

The study was recently published in the journal GIScience & Remote Sensing.

According to the study, while many modern 2D tracking techniques can provide valuable insights into glacier flow, previous studies tend to capture only short-term snapshots or else offer observations without in-depth motion analysis or high-resolution 3D data. This team’s work may help scientists keep better track of seasonal climate issues like glacier melt and expand long-term observations of these masses, and their 3D model method also reveals new data about how quickly the glaciers react to changes in the weather.

The Viedma and Skamri Glaciers, for example, exhibit a 45-day lag time in response to changes in local climate conditions like rain or snow. The La Perouse Glacier, however, was shown to react to changes almost immediately, meaning that its flow can very quickly become faster or slower based on how much precipitation it has accumulated.

In another finding, researchers concluded that behavior differences in all three are driven by distinct environmental and climatic conditions, but suggest that both local and global factors, rather than any single one, are responsible for patterns in glacier motion dynamics worldwide.

Such observations are vital to deepening our global understanding of glacier science, and with further improvements, this study’s algorithm could also be a useful tool for future disaster prediction and management, said Qin. Already, scientists have used similar systems to warn communities of natural disasters that would have led to tragedy.

In all, researchers hope that supporting modeling works like this one will inspire more scientists to utilize satellite data to investigate other types of important environmental research questions.

“Hopefully we can build on all sorts of applications that people are interested in with this,” said Qin.
