Summary
[edit]DescriptionAlgal bloom in the Lake Valencia - Venezuela.jpg |
English: This image, acquired by one of the Copernicus Sentinel-2 satellites on 12 January 2021, shows a massive algal bloom in Lake Valencia, in northern Venezuela. Lake Valencia, formerly Lake Tacarigua, is the largest freshwater lake in the country. Since 1976 the lake is affected by algal blooms caused by the continuous influx of untreated wastewater from the surrounding urban, agricultural, and industrial land uses. This contributes to ongoing eutrophication, contamination, and salinisation of the lake. Recently, the National Environmental Commission of Venezuela has indicated that the pollution of Lake Valencia as one of the urgent environmental issues which the country need to be addressed. The resolution of the Copernicus Sentinel-2 satellites (10 m in most of the spectral bands) allows to monitor biological activity and water quality around the world. |
