[:ja]アレックス・ゲルスト宇宙飛行士がISSから撮影したパタゴニアのウプサラ氷河です。
南パタゴニア氷原から連なる氷河の数は大小50以上、その規模は、南極、グリーンランドに次ぐ量といわれており、氷河はパタゴニアの特徴とまで言われています。
パタゴニアの氷河は温暖氷河に属し、アンデス山脈に降る多量の雨により涵養されます。非常に速く氷河が循環することで知られており、平均年間に100mから200m移動します。その中で、この画像のウプサラ氷河はアルゼンチンのロス・グラシアレス国立公園内にある最大の氷河です。南パタゴニア氷原から流れ出し、終端はアルヘンティーノ湖に至る距離は60km。かつてこの距離は80kmもあったことから、ウプサラ氷河の急速な後退を意味しており、地球温暖化の証拠といわれています。

[Earthview Wonders] No.575: Termperate Glacier of Patagonia🇦🇷
Astronaut Alex Gerst captured from ISS Upsala Glacier, Argentina.
Patagonia is a sparsely populated region located at the southern end of South America, shared by Argentina and Chile. The region comprises the southern section of the Andes mountains as well as the deserts, pampas and grasslands east of this southern portion of the Andes. The high rainfall against the western Andes (Wet Andes) and the low sea surface temperatures offshore give rise to cold and humid air masses, contributing to the ice-fields and glaciers, the largest ice-fields in the Southern hemisphere outside of Antarctica. The Upsala Glacier, as shown in the image, is a large valley glacier on the eastern side of the Southern Patagonian Ice Field.
The local scenery on the ground is as follows.
