\nThe Copernicus Sentinel-2 mission takes us over the \u2018meeting of waters\u2019 in Brazil \u2013 where the Rio Negro and the Solim\u00f5es River meet to form the Amazon River.\n<\/p>\n

\nThe Rio Negro, visible in black, is the largest tributary of the Amazon and the world\u2019s largest black-water river. It flows 2300 km from Colombia, and it gets its dark colouring from leaf and plant matter that has decayed and dissolved in its waters.\n<\/p>\n
\nThe Rio Negro contrasts significantly with the Solim\u00f5es River \u2013 visible directly below – which owes its brown-colouring to its rich sediment content, including sand, mud and silt. After flowing for around 1600 km, the Solim\u00f5es River meets the Rio Negro and together form this important junction.\u00a0\n<\/p>\n
\nOwing to differences in temperature, speed and water density, the two rivers, after converging, \u00a0flow side-by-side for a few kilometres , before \u00a0eventually mixing.\n<\/p>\n
\nManaus, the largest city in the Amazon Basin, is visible on the north bank of the Rio Negro. Despite being 1500 km from the ocean, Manaus is a major inland port. The Adolfo Ducke Forest Reserve is visible northeast of the city. The almost square-shaped block of land is a protected area named after the botanist Adolfo Ducke, and is used for the research of biodiversity.\n<\/p>\n
\nCopernicus Sentinel-2 is a two-satellite mission. Each satellite carries a high-resolution camera that images Earth\u2019s surface in 13 spectral bands and can help monitor changes in land cover and inland waters.\n<\/p>\n
