Bahía Blanca, Argentina: Green Sediments by a “White Bay” – October 12th, 201038.7S 62.2W
The coastline of the southernmost part of the Argentine province of Buenos Aires, near the city of Bahía Blanca (meaning “White Bay”) appears greenish due to sediments from the Naposta Stream. Some sediments can also be seen north of the Valdes Peninsula, situated at the bottom left edge of the image.
Since the city of Bahía Blanca is located at the limit between Pampas and Patagonia, it is warm and more humid to the north and varies rapidly to the south, becoming drier. This change from Pampas to Patagonian steppes is evident in the image, as the northern parts appear greener and more fertile, while the southern parts appear browner and drier.
