The barrier islands of Louisiana are vital for the protection of Louisiana’s coastal communities and its natural resources. They are the first line of defense from summer’s hurricanes and winter’s storms. However, barrier islands are no longer building naturally. The previously-illustrated cycle has been interrupted by “reoccupation” to the natural processes that drive it. For “reoccupation”, stage five of the barrier island termination model, to occur, completely natural conditions that allow the river to rebuild its delta are required. These conditions do not exist because people have altered the course of the Mississippi River to control it from flooding and for navigational purposes.
Barrier islands contain a variety of habitat zones, all

These are called barrier islands. Most are long and thin, oriented parallel to the shoreline. These islands have many things in common but also have many different characteristics. They all consist of a sandy beach facing the ocean or Gulf with several other habitat zones including dunes, swales, maritime forests, marshes and tidal flats. The specific natural environments vary from island to island. The bays, estuaries and lagoons found behind the islands are typically rich in marine life. The islands serve to protect these ecologically valuable places. These small land masses also protect human communities on the mainland from the destructive energy of tropical storms and hurricanes. Despite their protective function, barrier islands are very dynamic and always on the move. Their formation depends upon the movement of sand by waves, tides and currents, and these forces continue to act on all barrier islands. Many barrier islands are popular vacation sites. Resort towns have been developed on many of these islands. However, attempts to prevent erosional forces from threatening human-built structures are usually
Barrier Islands are very so hard to protect, therefore, there should be different kinds of information that would help the community distant from these Coast's to commit to preserving a Barrier Island. first of all historically these barrier islands have been hard to protect because the links between them an inshore ecosystems are poorly recognized. some of the ways resolve this issue include putting signs up roads that lead to the coast, putting Billboards up making tissue blown up on a big board, sending mass text out like they do with Amber Alerts, creating symbols or texts on the roads themselves like we have with turn signals, putting more information on local channels for TV, putting Flyers up at local restaurants or bars,
* The sand dunes on the beaches. This area is affected by wind erosion as well as the tides if adequate vegetative cover is not present. The main type of erosion, from the sea, takes the sand from the sand dunes as well as the rest of the beach in a rip. The sand is then pulled out to sea where it forms a sand bar. On calmer days, the sand is brought back to the beach.
There are many different types of coasts that exist throughout the United States. The south shore of Long Island has a unique types of coast known as a barrier beach. Barrier beaches are long narrow land forms that are composed of sand and other lose sediments. These sediments are brought together by the actions of waves, currents and storm surges. Barrier beaches are subject to constant changes by the same forces. Sand is constantly eroded in one area an deposited in another. Barrier coasts are important for a number of reasons; they protect the mainland of Long Island from the open ocean and flooding during storms, for recreational use and the unique ecosystems which exist on barrier
Man and nature have worked together to reshape the environment in coastal Louisiana. The Mississippi slows when it reaches the
Warming oceans might trigger an eruption of methane now frozen beneath the sea floor, leading to global warming on a catastrophic scale.
The story of Easter Island is still somewhat a mystery, but the overall understanding of how that culture met its demise was because of a lack of resources on the island. On another account, the story of the Lorax is no mystery in that we know that the destruction of that environment was due to the production of the Thneeds. Now, the stories are seen as completely different situations since one story is historical and the other is a cartoon. However, in some ways, the story of Easter Island and the Lorax, while still being different, are more similar than most people may recognize.
There are seven amazing places in the world, that have left many in wonder. The Great Barrier Reef, Victoria Falls, Paricutin Volcano, Mount Everest, The Harbor of Rio de Janeiro, The Northern Lights and The Grand Canyon. These places are all naturally made. Naturally made places always seem more beautiful than man made places. That’s because they’re a gift from mother nature. These incredible places have lots more too them than you may think.
Easter Island shows that we need to conserve what we can so resources do not become depleted and
Next time you visit a Caribbean beach, take a look at the large rocks submerged under the sand. From afar, they appear identical to boulders on land; up close, however, a great deal of fissures and grooves can be seen, distinguishing it from land-based rocks. What then, could’ve formed these reef rocks if they are so different looking? Chances are, they were formed by coral, most likely of the genus Acropora. The two species of Acropora corals that reside in Caribbean reefs are Acropora Palmata (elkhorn coral) and Acropora Cervicornis (staghorn coral).. Both corals are extremely important residents of the Caribbean reef, performing many functions such as reef-building. Their highly-structured biology permits them to do so, and the ecology between
The Easter Island heads. Rapa Nui has been a place of mystery since it was discovered in 1772. The name “Easter Island” is the European name given by Jacob Roggeveen. The mystery on Easter Island is the moai, otherwise known as the heads of Easter Island. How the moai got there is still in debate but there have been multiple proven theories of how they got there. The three main theories I will discuss are the rope theory, the wooden sledge theory and the walking theory.
They say that perfection is not attainable, but what if in this messed up world there is another land where you go when you’re tired of all the imperfections. Sometimes everyone gets way too overwhelmed with life and stressed about the little things and the big things. There is an island in the Indian Ocean where all your worries will wash away. In order to get on this island you will need to explain the situation in your life and then a panel of people will decide if you meet the requirements to go to this therapy island. This is not somewhere where you can move and live forever, instead it is a little escape from life and after a certain period of time you will be required to leave. Only a certain amount of people are allowed on this
(The Great Barrier reef is one of the world’s seven natural wonders- simple). The reef is made up of vibrantly colored corals and lots of marine life, but the last coral bleaching event killed 35% of the reef’s coral. The Great Barrier Reef is constantly changing due to coral bleaching. If the people of the world are not careful they may lose one of the world’s seven natural wonders.
I was a happy Tortoiseshell live in Barrier Reef,I use to swim in the none pollution water and having a Sumptuous lunch in the coral.I thought it would be last forever,but the nightmare had comes.
The purpose of island biogeography is to help take a closer look at the speciation of animals on mainland landscapes, and compare them to surrounding islands that separated from the mainland. In this study, the focus is on avian birds and the differences in landscape make up that can influence speciation. The differences can possibly lead to populations of different species settling apart from one another, maybe leading to the extinction of one species and the thriving of another. Although island geography has been a useful tool, it has also been questioned, leading to a new tool: countryside biogeography. In Wolfe et al. (2015) it is explained how countryside geography is a tool that can be used to look at different aspects of speciation in
Long shore currents continuously transport sand south along the coast. Harsh winter weather pulls sand from dunes and upper beaches, depositing it onto offshore sand bars and reducing beach width, while gentler wave action during milder summer weather acts to restore the shoreline (NOAA, 2013.) The structure of barrier islands is determined by the movement of sand in the littoral zone, which is the land-facing side of the island. In August of the year 1933, a hurricane created an inlet south of Ocean City, Maryland. The inlet separated the island from Maryland (U.S. National Parks Service, 2012.) After the hurricane, a permanent system of artificial jetties was built for navigation purposes, and has drifted westward considerably from the original landmass; without the jettisons, it would have silted back because of longshore drift which is a geographical process that consists of the transportation of sediments, such as clay, silt, sand, and shingle along a coast at an angle to the shoreline, which depends on prevailing wind direction, amongst other factors, This process occurs in the littoral zone, and is on in or close to the surf zone. The artificial jettisons has created wider beaches and better fishing access, but also has caused erosion problems on Assateague Island. As an added note, Assateague island is well known for their white sand
