Sediments in Gironde Estuary and Around Île d’Olerón, France

France – November 22nd, 2012

Sediments pour from the Garonne and Dordogne Rivers, through the Gironde Estuary, and into the Bay of Biscay. They also frame the shores of western France, near the estuary, and surround the Île d’Oléron, an island due west of Rochefort, on the southern side of the Pertuis d’Antioche strait. With an area of about 174 km2, it is the second largest French island after Corsica.

United Kingdom and France - March 28th, 2012

Sediments can be observed in the English Channel, separating the United Kingdom (above) from France (below, right), and along the western coast of France, particularly in the Gironde Estuary. The Gironde is formed from the meeting of the rivers Dordogne and Garonne just below the centre of Bordeaux. Covering around 635 km2 (245 sq mi), it is the largest estuary in western Europe.

France - January 4th, 2012

The Gironde Estuary, formed by the confluence of the Garonne and Dordogne rivers, is the largest estuary in Europe at almost 50 miles (80 km) long and up to 7 miles (11 km) wide. The estuary’s average discharge rate into the Atlantic is 265,000 gallons (1 million liters) per second.

It has a large tidal range, of up to 16 ft (5 m) during periods of spring tide, and the strong tidal currents in the estuary, as well as numerous sand banks, tend to hamper navigation. One of the Gironde’s most impressive features is its tidal bore—a large, wall-like wave at the leading edge of the incoming tide—known locally as the Mascaret. Occurring with each flood tide at the time of spring tides (that is, twice daily for a few days every two weeks), the bore surges from the Gironde upstream into its narrower tributaries. On the Garonne, the Mascaret sometimes forms a barreling wave, which can reach a height of 5 ft (1.5 m) and tends to break and reform.

France - December 26th, 2011

Here, sediments from the Gironde Estuary create paisley patterns in the waters of the Bay of Biscay, off the west coast of France. The Gironde is a navigable estuary, formed from the meeting of the rivers Dordogne and Garonne just below the centre of Bordeaux (visible at the bottom edge).

The Gironde is approximately 65 km (40 mi) long and 3–11 km (2–7 miles) wide. Covering around 635 km2 (245 sq mi), it is the largest estuary in western Europe. The Gironde is subject to very strong tidal currents and great care is needed when navigating.

Bordeaux is located close to the European Atlantic coast, in the southwest of France and in the north of the Aquitaine region. The city is built on a bend of the river Garonne, and is divided into two parts: the right bank to the east and left bank in the west. The left bank of the Garonne is a low-lying, often marshy plain.

France - October 14th, 2011

Sediments give the Gironde, on the western coast of France, an opaque tan color. Then they give a greenish tinge to the coastline as the diffuse into the waters of the Bay of Biscay. The Gironde is subject to very strong tidal currents and great care is needed when navigating by any size or type of boat.

The Gironde is a navigable estuary (often falsely referred to as a river), in southwest France and is formed from the meeting of the rivers Dordogne and Garonne just below the centre of Bordeaux. Covering around 635 km2 (245 sq mi), approximately 65 km (40 mi) long and 3–11 km (2–7 miles) wide, it is the largest estuary in western Europe.
