New Data Platform for #Arctic #Permafrost Lakes

Researchers at the Alfred Wegener Institute have developed the "Lost Lakes" database, which provides important information on the status of Arctic #thermokarst lakes - both in real time and over extended periods.

“Can we develop a first-order understanding of permafrost degradation and glacial lakes exposed to degradation-induced mass movements in the Himalaya?
[The authors] tried to address this question. The study [first link above] integrates machine learning, statistical modeling, and numerical modeling to investigate high-resolution permafrost distribution, potential degradation, and associated mass-movement hazards in the Kinnaur district of Himachal Pradesh, India.
Using rock glaciers as proxies, [they] generated a high-resolution permafrost distribution using machine learning, while potential degradation zones were delineated using the 0°C isotherm as a first-order indicator. [They] further identified glacial lakes located near potentially degrading permafrost zones and reconstructed their bathymetry. A detailed scenario-based GLOF process-chain simulation was then carried out for Kashang Lake using r.avaflow and HEC-RAS.
[Their] results indicate that seven glacial lakes in #Kinnaur are located close to potentially degrading permafrost zones. The simulations further show that a potential GLOF from Kashang Lake could inundate critical downstream infrastructure, including nearly 11 km of National Highway 5…”

Das Tauen der #Permafrostböden in der #Arktis gefährdet bis zu drei Millionen Menschen.

#Erosion, #Erdrutsche und die Freisetzung von #Schadstoffe​n bedrohen #Infrastruktur, Wasser- und #Nahrungsversorgung.

Auch #Krankheitserreger aus dem gefrorenen Boden könnten gesundheitliche Risiken bergen. Diese Entwicklungen sind keine #Zukunftsprobleme, sondern bereits Realität.

Permafrost Thaw 🧊🔬

The thawing of #permafrost is associated with the release of several significant components, including:

• Ancient #microorganisms that may harbour #antimicrobial resistance (AMR) genes

• Accumulated pollutants and #HeavyMetals

• #Methane, which plays a role in accelerating #ClimateChange

• Newly created #ecological niches that may support #pathogens

Der #Methangehalt der #Atmosphäre steigt seit einigen Jahren dramatisch und mehr als erwartet. #Wissenschaftler suchen daher mit Hochdruck nach den Ursachen.

Eine davon: Tropische #Feuchtgebiete geben bis zu 1,4 Millionen Tonnen mehr #Methan pro Jahr ab.

Versteckt im Permafrost: Studie nimmt 13 vergessene #Viren unter die Lupe (futurezone)
Im #Permafrost gefangene #Krankheitserreger sind nicht zwingend tot. Forschende haben sie im Labor reaktiviert. Frühere Untersuchungen hätten fälschlicherweise nahegelegt, „dass ‚Zombie-Viren‘ keine Bedrohung für die öffentliche Gesundheit darstellen“
