Ancient rocks reveal critical metal origin and continent-breaking forces

Researchers found that newly discovered niobium-rich carbonatites were formed more than 800 million years ago – rising from deep within the Earth through fractures of the crust during a tectonic rifting event that ultimately tore apart the supercontinent known as Rodinia: www.uni-goettingen.de/en/3240.html?id=7909

🌍 Our WAS seismometer in Westport, CT picked up a magnitude 6.0 earthquake that struck eastern Afghanistan near the Pakistan border on Sunday.

📍 Location: 27 km NE of Jalalabad, Nangarhar Province
⏰ Time: 11:47 p.m. local time
📏 Depth: 8 km
⚠️ USGS models estimate the shaking could cause significant casualties.

Even from thousands of miles away, our instruments can "hear" the Earth’s rumble. cnn.com/2025/08/31/asia/afghan

How that I have your attention 😉 I would like to exploit it for some work stuff. #RemoteSensing #ImageProcessing communities, I have a real quest. We're segmenting shallow underwarter structures in these archival aerial photos (grayscale, single-band) and the segmentation algorithm picks up... the waves on the water surface, not reefs and such. This gives an artefactual vergence (direction) that is not present in the layer we are interested in, i.e. sea floor. This is SVM in eCognition. Don't mention segmentation in ArcGIS (unless you're a powerful wizard, in that case I bow).
We also have a custom ML model but it's not that good either (yet?). How to get rid of them waves?! #geoscience #EarthObservation
