[:ja]宇宙飛行士がISSから撮影したミシシッピー川デルタです。No. 809の通り、ハリケーンバリーがルイジアナ州に上陸擦る前から、ミシシッピー川の水位が高く危険な状態が続いていたことを紹介してきました。
ミシシッピ・デルタは、ミシシッピ川とヤズー川に挟まれた領域で、大きさは南北320km、東西112km、面積約17,870km2におよぶ広大な沖積平野です。当初は低地全体を硬木の森で覆われていたこの地域は、南北戦争（1861年-1865年）前の時代に国内でも最大級に肥沃な綿花栽培地域として開発され、多くの投機家が惹きつけられ、綿花プランテーションのために川沿いの土地を開発しました。彼らは黒人奴隷の労働力に頼る裕福な農園主となり、南北戦争よりもかなり前に黒人が人口の過半を占めることとなり、白人の2倍になるところも多かったようです。アフリカ系アメリカ人はブルースやジャズという形で音楽を発展させた。デルタ地域の郡部住人の大半は黒人でしたが、20世紀前半に起きた大移住時代に40万人以上のアフリカ系アメリカ人が、北部、中西部、西部の工業都市に移転して行きました。ミシシッピ・デルタは度々大きな洪水に見舞われ、1927年のミシシッピ大洪水や2011年の洪水が有名です。

[Earthview Wonders] No.812: Mississippi River Delta🇺🇸
Astronaut on board ISS captured the Mississippi River Delta. As introduced with No. 809, the water level of Mississippi River has been high for the past year before the Hurricane Barry landed on Louisiana.
The Mississippi River Delta is the vast river delta at the confluence of the Mississippi River with the Gulf of Mexico, in Louisiana. As the birthplace of jazz, the delta provides an array of natural habitats and resources that benefit the entire nation. The coastal wetlands have a number of diverse landscapes that connect a variety of habitats to both the land and water. Louisiana’s wetlands are one of the nation’s most productive and important natural assets. Consisting of natural levees, barrier islands, forests, swamps, and fresh, brackish and saline marshes, the region is home to complex ecosystems and habitats that are necessary for sustaining its unique and vibrant nature. The Mississippi River Delta has a strong economy which relies heavily on tourism and recreational activities such as fishing, hunting and wildlife watching as well as commercial fishing, oil, gas, and shipping industries.
The local scenery on the ground is as follows.
