  Stained Winyah Bay

  November 1, 2020 - North Carolina, USA - Four blackwater rivers, the Waccamaw, Pee Dee, Black, and Sampit, feed into Winyah Bay, an estuary in eastern South Carolina. All of them flow through swamps, wetlands, and forests that are rich with decaying vegetation and other organic matter. The dead leaves and debris stain the rivers and wetlands a transparent brown color as several natural chemical substances found in plants, tannin, phenol, and humic acid, seep into the water. The same process gives tea its yellow or brown color. (Credit Image: © NASA Earth/ZUMA Wire/ZUMAPRESS.com)、クレジット：©ＮＡＳＡ　Ｅａｒｔｈ／ＺＵＭＡ　Ｗｉｒｅ／ＺＵＭＡＰＲＥＳＳ．ｃｏｍ／共同通信イメージズ
