[:ja]ルカ・パルミタノ宇宙飛行士がISSから撮影したブラジル、アマゾン川本流域のサンタレン付近です。
アマゾン川は、生物多様性の観点から極めて重要な役割を担っています。アマゾン川は長年生態的条件や気象的条件が比較的安定していたため、セルバと呼ばれる熱帯雨林や水中の世界でも、豊かで多様性に富んだ動植物が数多く見られます。アマゾン川流域には、約250種類の哺乳類、約1,800種類の鳥類、特に昆虫全体に至っては、100万種以上が生息していると推測されています。ちなみに、サンタレンはタパジョース川がアマゾン川に注ぎこむ地点に位置し、やや温かく濃い青色のタパジョス川の水と、アンデス山脈からの土砂を多量に含むため茶色のアマゾン川の水が混ざり合うことなく数キロに渡って町の前を流れていく光景は多くの観光客をひきつけます。

[Earthview Wonders] No.1130: Amazon River🇧🇷
Astronaut Luca Parmitano captured from ISS Amazon River near Santarém, Brazil.
As can be seen from the image, the Amazon has many tributaries. The numerous thinner lines show the many remnants of prior channels of this highly mobile river. The reflected sunlight even shows numerous ponds which are usually not visible due to the dense forest cover in central Amazonia. Santarém is bordered by the Amazon and the Tapajós rivers. Both run along many kilometers in the front of the city, side by side, without mixing. Amazon’s milky colored water carries sediment from the Andes in the East, while the Tapajós’s water is somewhat warmer and has a deep-blue tone. This phenomenon is called “The meeting of the waters” by the locals.
The local scenery on the ground is as follows.
