HIGHLIGHTS:
• Proposed U-ViT model based on Prithvi GFM for multi-sensor glacial lake mapping.
• Achieved an F1 score of 0.894 on Sentinel-1&2, surpassing CNNs scoring below 0.8.
• Maintains strong performance with 50% less training data, proving efficiency.
• Excels in detecting small lakes (<0.01km²) and handling clouds and complex terrains..."

“A rush of water unleashed by an ailing glacier swelled an Alaska river to record levels Tuesday and caused destructive flooding in Juneau nearly a year to the date of a similar significant event.
More than 100 homes have been damaged or impacted by the so-called glacial lake outburst flooding along the Mendenhall River in the Mendenhall Valley, according to city officials, who characterized the flood severity as “unprecedented.”
Glacial lake outbursts happen when a lake of melting snow and ice and rain “drains rapidly…”

Fjallsárlón is a special place. This glacial lagoon is not as big nor spectacular as Jökulsárlón, but both times I’ve been it was really quiet - hardly anyone around. You can see so much here, including the ice flow down the mountainside.

I tried to capture the glacier snout with a 300mm lens. I didn’t have a tripod, the light was fading & the lens was heavy, but i was pleased with how it came out
