The Copernicus Sentinel-2B satellite takes us along the lower reaches of the brown, sediment-rich Uruguay River. Here, the river forms the border between Argentina and Uruguay and is the site of the Esteros de Farrapos e Islas del Río Uruguay wetlands.

A tourist attraction and a waterway for transport, the Esteros also play an important role in regulating flood levels and maintaining water quality, as well as safeguarding the banks of the Uruguay River from erosion.Visible to the lower left – its built structures shown in grey-white – is the Argentinian town of Gualeguaychú. On the eastern shore of the Uruguay River is the Uruguayan city of Fray Bentos, an important national harbour, famous for a plant that once exported corned beef around the world. Now inactive, this sprawling industrial complex has become a World Heritage Site.

The dark green area to the east of the Esteros is devoted to forestry, an important industry for the region. A pulp mill is located close to Fray Bentos.

Sentinel-2 is a two-satellite mission to supply the coverage and data delivery needed for Europe’s Copernicus environmental monitoring programme. The mission’s main instrument has 13 spectral bands, and is designed to provide images that can be used to distinguish different types of vegetation and monitor plant growth.
