The Gironde Estuary and the Pertuis d’Antioche, France’s Western Coast

Western coast of France - March 9th, 2009

Western coast of France - March 9th, 2009

Sediments flow from the Dordogne and Garonne Rivers, through the Gironde Estuary (bottom right quadrant), and into the Atlantic Ocean off the western coast of France.

The rivers appear completely tan where they merge, near the city of Bordeaux (bottom right corner). This tan color takes on a progressively greener tint as the estuary widens.

Further up the coast, the waters of the Pertuis d’Antioche, a strait between the two islands Île de Ré and Île d’Oléron and the continental coast, between the cities of La Rochelle and the naval arsenal of Rochefort, are also tinged green by sediments.

The Pertuis d’Antioche is bordered by a limestone coast dating back to the Cretaceous Period, at which time is was deep under water.

Condensation Trails over France – December 1st, 2008

Condensation Trails over France - November 27th, 2008

Condensation Trails over France - November 27th, 2008

Condensation trails create criss-cross patterns over western France, near Bordeaux, Limoges and La Rochelle, in this full resolution image.

Condensation trails, also called contrails or vapour trails, are visible trails of condensed water vapour made by the exhaust of aircraft engines.

As the hot exhaust gases cool in the surrounding air they may precipitate a cloud of microscopic water droplets. If the air is cold enough, this trail will comprise tiny ice crystals.

In addition to the white lines of the condensation trails, we can also see snowfall over the Massif Central (right) and in some valleys closer to the coast.

By the coast, we can see sediments in the Gironde Estuary, where the mouths of the Garonne and Dordogne rivers merge.
