No other North American river has a drainage basin as large as that of the Mississippi. The amount of nutrients it discharges into the Gulf of Mexico is correspondingly large. Because freshwater from the river is lighter than the salty seawater, it settles as a distinct layer above the seawater. This phenomenon is called stratification. The freshwater layer acts like a blanket to prevent the exchange of gases, oxygen for example, between the seawater and the atmosphere. This kind of stratification is also observed in other coastal areas, such as in the Baltic Sea between Denmark and Sweden, and in the Norwegian fjords. In the case of the Mississippi River, however, the situation is exacerbated by the especially high levels of nutrients it contains. The presence of the nutrients leads to profuse algal growth. When the algae die their remains sink into the lower water layer. There they are broken down by bacterial activity, a process that consumes oxygen. This causes the oxygen levels in the deep-lying saltwater layer to drop drastically. Free-swimming organisms flee the area due to the oxygen deficiency. Less mobile animals such as mussels die. For this reason, the low-oxygen areas off the coasts of Louisiana and Texas are called “dead zones“. In 2002 an oxygen-deprived area of more than 20,000 square kilometres was observed. This is equal to half the area of Germany. There is considerable evidence that the oxygen problem associated with stratification has only begun to occur more frequently since the middle of last century. The increase is probably due to the rising nutrient concentrations, especially nitrogen, which has trebled since the 1950s. Stratification in the northern Gulf of Mexico is, in fact, a natural phenomenon that is especially pronounced during years with high rainfall. Storm events like hurricanes can cause effective mixing of the water, and even counteract the effects of stratification. But the nutrient transport of the Mississippi River is still too great. A management plan has now been adopted to attempt to reduce the nutrient input, with an aim of limiting the maximum area of the dead zone to around 5000 square kilometres. The measures being applied include improved wastewater treatment, optimized fertilization practices, and the creation of flood-plain areas along the rivers, which would absorb significant amounts of the nutrients.

 4.5 > The Mississippi River carries vast amounts of sediments (yellow-brown) and nutrients into the Gulf of Mexico, which are then transported westward along the coast by the wind. The nutrients cause a strong growth of algae (green). Oxygen is consumed in the deep water as bacteria break down the algae. This results in a completely oxygen-depleted dead zone along a broad strip of the US coast.
Every Texan knows what color the water in Galveston is: brown, with a tinge of sickly greenish yellow. The Gulf of Mexico’s unfortunate hue, combined with not-quite-white beaches, tarballs, the occasional sargassum invasion, and a horizon dotted with offshore drilling platforms, are what give the Oleander City its peculiar charm. It may not be South Beach or Saint Tropez, but it is just 45 minutes from Houston on I-45. (Depending on the traffic, of course.) So imagine the surprise of visitors who arrived in Galveston over Memorial Day weekend to discover crystal-clear, aquamarine water lapping against sugar-white sand. Word of the miraculous transformation quickly spread through social media, along with photographic proof. Local news stations sent helicopters into the air to capture the blue water from above, andABC 13 Houston illustrated the change by juxtaposing file footage of how the water typically looks next to recently taken video. https://twitter.com/abc13houston/status/1001964083158110208 Ordinary beachgoers posted unexpectedly glamorous selfies and tweeted out their shock.
The beautiful scenery left local business people surprised–and unusually bereft of customers. Emma Reed, a bartender at the rooftop bar of the Tremont House hotel in downtown Galveston, was expecting a busy Memorial Day weekend. Instead, the bar was nearly empty. “I guess the water brought all the people down to the beach,” she said on Wednesday, when the water had returned to a more familiar shade of beige. “Every now and then we’ll get a nice blue-green, but I’ve never seen the water that blue.” City officials attributed the unexpected cerulean waters to the “current changing from east to west,” as the scientists at the National Weather Service speculated that Subtropical Storm Alberto may have pushed a “plume” of clear water toward the Gulf Coast on its way up the east coast. (Sediment churned up from the Houston Ship Channel—not pollution, as is sometimes alleged—is largely responsible for Galveston’s typical brown water.)
Galvestonians recognized the turquoise water as unusual. “Normally the water doesn’t get that way until the end of August, when the prevailing winds start switching around,” said Stephen Sollenberger, a longtime local, while sitting on a beach chair on the Seawall on Wednesday, next to the Duck Tours amphibious truck he co-operates. “They say it’s because of the storms we just had.” Weekend visitors were just happy to time their visit for the clear waters. Friends Candace and Christy, who had traveled to Galveston on vacation from Dallas and Kentucky, respectively, were sitting on the beach under the shade of umbrellas near the Pleasure Pier on Wednesday. (They declined to give their last names.) “It was bluer yesterday, but it’s still more blue than we had been told to expect,” Candace said. “It’s definitely darker today,” Christy added. A reality check of sorts came from Calvin Browne, who lives in Sugar Land but was born and raised in Barbados. He was enjoying a drink on the Tremont House rooftop bar, which overlooks the Galveston harbor. “I know blue,” he said when asked what he thought of the water. “Let’s just say there’s room for improvement.”
The brown water has nothing to do with pollution. It is simply due to the way the earth was constructed. Many blame the Gulf oil spill but it has been long cleaned up from the waters. Also the water was brown long before the spill happened. Why is Gulf of Mexico water dirty?

Why is the Mississippi Sound Brown?Waters of the Mississippi Sound are clean but brownish in color.

The reason the ocean is blue is due to the absorption and scattering of light. … Almost all sunlight that enters the ocean is absorbed except very close to the coast. The red yellow and green wavelengths of sunlight are absorbed by water molecules in the ocean. Why does Black Sea have no oxygen?“This fresh water which is less dense than sea water colonises the upper layers of the water column without mixing with the lower layers.” Because the lower layers are far more saline. … The marine food chain therefore develops above this boundary below which the waters are devoid of oxygen. Is water blue or clear?
The water is in fact not colorless even pure water is not colorless but has a slight blue tint to it best seen when looking through a long column of water. The blueness in water is not caused by the scattering of light which is responsible for the sky being blue. Why is water in Caribbean so blue?
The Caribbean is such a light a shade of blue due to the tendency of the Caribbean coast to scatter sunlight. The fact that the sand is light colored and the water is relatively shallow also makes the water appear turquoise. Why are tropical waters so blue?
Most of the Caribbean has that turquoise blue color because of the shallow depths. The deeper the ocean the deeper the shade of blue because the sunlight can’t reach the bottom. When the water is deeper it absorbs all the sun rays creating a darker shade. So the more shallow the water the lighter the blue. Why is Bahamas water so clear?The reason that the water in the Bahamas and Hawaii is clearer than along the California coast is likely a combination of both of these factors: 1) the sediments in the Bahamas and Hawaii tend to be composed of heavier particles that are not as easily stirred up or suspended and 2) there tends to be far less … What is the dirtiest beach in America?
