How the mournful songs of icebergs reverberate around the world
Icebergs produce some of the loudest natural noises in the oceans. Can we learn anything about their birth, life and death by listening in?
By Richard Gray
Caption figure below: Iceberg songs are generated by harmonic tremours that occur when icebergs rub against each other or scrape along the seafloor
@mattotcha Des anomalies d'isotopes de plutonium ont été découvertes dans les glaciers de l'hémisphère sud, révélant des traces de contamination radioactive. Ces résultats soulèvent des questions sur l'impact des activités humaines sur les environnements éloignés. La recherche continue d'explorer ces effets, soulignant l'importance de la surveillance environnementale. #Plutonium #Glaciers #Environnement #Science

Back to the WMO today (online at least) to discuss the global #Cryosphere watch - a part of @wmo-global.bsky.social - and how we can better share real-tiem and climate data affetcing #glaciers #ice sheets and other parts of hte cryosphere.
Rising sea levels, melting #glaciers, heatwaves at sea – 2023 set a number of alarming new records.
The global mean #temperature also rose to nearly 1.5°C above the preindustrial level, another record.
Seeking to identify the causes of this sudden rise has proven a challenge for researchers.
The potential cause is a decrease in Earth's #albedo due to changes in cloud patterns, corresponding to another positive feedback loop amplifying the warming.

I just love trail running! But when I can also be out and about in magnificent landscapes, like here at the Bovalhütte in the Engadin, it's the perfect combination! I just love these glacier landscapes! They never cease to amaze me, even if they're getting smaller and smaller.

After some time of trying mastodon, I quite like it here and will probably stay so it's maybe time for an introduction:
I'm a student in physical #oceanography in northern germany and mainly here for finding interesting research related content. Second interest is just general #opensource stuff & programming and third is politics.
For the research part I'm mostly a fan of #hydrothermalvents , #oceans , #climate , the #arctic , #antarctic , #glaciers , #seaice but also #ships and more.
@DrEvanGowan I had a similar thought when looking at the ages and the materials that were dated. Nonetheless, it's fun that there can still be such debate over a thousand-km difference in the position of the ice margin! I'll be interested to see the new data from Manitoba. #glaciers #geology #quaternary
Iowa may not be the first thing to come to mind when you think of #glaciers, but continental ice sheets reached the central United States many times. This recent paper presents evidence that the ice sheet was in #iowa at a time when many other reconstructions suggest that it was restricted to northern Canada. A puzzle that has implications for #paleoclimate, ice sheet reconstructions, and global sea level during the lead up to the last glacial maximum. https://onlinelibrary.wiley.com/doi/full/10.1002/jqs.3627
Sharing some big mountain vibrations. You ever reach a view that is so beautiful you cant stop taking pictures? This was that moment for me, catching the last rays of daylight. Since it was quite cold the group I was with didn't stick around long. I have a hard time leaving these places, especially knowing how rare it'll be to ever return again. If you zoom in you can see some mighty glaciers deep within the Canadian Rocky Mountains. Grateful to be able to share such a memory.

This week's #NewBooks at the library: I chanced upon a very affordable copy of Atlas of Submarine Glacial Landforms from the #GeologicalSociety. A rare Dutch addition this week is De Thigmofiel by one of my favourite Dutch biologists, #MidasDekkers. Lastly, I offered sanctuary to a damaged copy of #Evolution and Fossil Record of African #Proboscidea from CRC Press
