USA, Mexico and Cuba – December 22nd, 2012

Sediments can be seen along the southwestern coast of Florida, USA (upper right), in the Gulf of Batabanó, Cuba (center right), along the western and northern coasts of the Yucatán Peninsula, Mexico (lower left) and by the Mississippi River Delta in Louisiana, USA (upper left). In the former three, the bright, light color is in part due to sediments and in part due to shallower depths.

Of particular note in Florida are the Everglades. Beginning in 1948 with the creation of the Central and Southern Florida (C&SF) Flood Control Project, much of the original greater Everglades ecosystem was drained in an effort to create a system of canals and dikes that would control the flow of water and accommodate agriculture and urban development. Some 50 percent of the original Everglades has been lost to agriculture and development but the majority of the remaining original Everglades acreage is now protected in a national park, national wildlife refuge, and water conservation areas.

USA – November 15th, 2012

While the greyish white streaks at the top of the image are clouds of water vapor, many of the other streaks in the image are plumes of smoke from fires burning in southern Louisiana, USA. Shifting winds cause the plumes to blow in various directions. Many of the fires, best observed in the full image, are clustered in the Mississippi River Delta, in the lower right quadrant.

Sediments in Mississippi Delta, USA

USA - April 8th, 2012

Tan sediments can be seen spilling from the Mississippi River into the Gulf of Mexico in the lower right quadrant of this image of Louisiana, USA, while the rest of the delta is flanked by darker brown sediments. The Mississippi River Delta is the modern area of land (the river delta) built up by alluvium deposited by the Mississippi River as it slows down and enters the Gulf of Mexico. The deltaic process has, over the past 5,000 years, caused the coastline of south Louisiana to advance gulfward from 15 to 50 miles (24 to 80 km).

New Orleans and Mobile Bay Along Southern USA Shoreline

USA - August 1st, 2011

This wide-swath ASAR image stretches along the southern shoreline of the United States of America along the Gulf of Mexico, from Louisiana (left), to Mississippi, to Alabama, to the Florida Panhandle (right, visible upon opening full image). New Orleans and part of the Mississippi River Delta arm, in Louisiana, can also be seen entering the image from the left edge.

Bodies of water of note in this image include Lake Pontchartrain, north of New Orleans, and Mobile Bay, an inlet of the Gulf of Mexico, lying within the state of Alabama. Its mouth is formed by the Fort Morgan Peninsula on the eastern side and Dauphin Island, a barrier island on the western side.

Mississippi and Red Rivers Flowing to the Gulf of Mexico – January 1st, 2010

The Mississippi River snakes its way southward towards the Gulf of Mexico, marking the border between the states of Louisiana (west) and Mississippi (east) as it goes. Also flowing toward the Gulf, diagonally from the left edge, is the Red River. The valleys around both rivers appear tan, in contrast to the rest of the states’ green terrain.

Upon reaching the Gulf of Mexico, the rivers release heavy loads of sediments, coloring the water tan, gold and green as they diffuse. These sediments are particularly dense by the Mississippi River Delta, south of the city of New Orleans.
