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..."

We thought that when #SeaLevel dropped during the #glacial maximum, the #RedSea became hyper-saline, and everything died. But there are some new ages and data from deep-sea #corals in the northern Red Sea, which suggests that was definitely not the case. https://www.pnas.org/doi/10.1073/pnas.2415559122

"SITE SANTA FE presents #Glacial Optics, a solo exhibition by Tristan Duke.

"In 2022 the artist sailed to the Arctic to capture portraits of the glaciers, using a camera lens made from their very own ice."

The fast-eroding cliffs at #Happisburgh, Norfolk exhibit splendid exposures of a "tripartite" (like neapolitan ice cream) Quaternary #geological succession - massive brown/grey #glacial till at the base, overlain by dark, laminated pro-glacial lake muds, then by glaciofluvial sands.
Two photos show infilled channels in the upper surface of the till, and one shows where the upper two units have been eroded back, exposing the upper surface of the half million year old Happisburgh Till Member.

So yeah, things are changing rapidly in the #GulfOfMaine. After years of record #OceanWarming, now all of a sudden the deep waters have gotten VERY cold. Could it be melting #glacial waters? A change in the #AMOC? I'll be keeping an on this story...!
