Sediments seep out of the shores of southern Louisiana, particularly around the mouth of the Mississippi River (lower right), giving the waters of the Gulf of Mexico varying brown and green hues. Sediments and algal growth can also be seen in Lake Pontchartrain, with the city of New Orleans visible as a grey area along its southern shores.

Fires in Louisiana, USA - April 24th, 2012

Texas Bays - April 21st, 2012

Sediments - April 18th, 2012

Plumes of smoke from fires both east and west of the Mississippi River are visible in this image of Louisiana, USA. The largest fire can be observed near the coast to the east of New Orleans, releasing a plume of smoke in a southerly direction.

New Orleans appears as a greyish tan area on the banks of the Mississippi River and the shores of Lake Pontchartrain. Sediments from the Mississippi River color the waters of the Gulf of Mexico a brown color in the delta region. A slight phytoplankton bloom can be seen near the bottom edge in the lower left quadrant.

The detail images show sediments in the Gulf of Mexico: the first focuses on sediments in the gulf between the city of Houston, Texas (left) and Vermilion Bay, Louisiana (right). The bay is full of brown sediments, while those further down the coast line create swirled patterns of green and blue. The second detail images shows sediments in numerous, interconnected bays along the coast of Texas, approaching the border with Mexico.
