Importance Of Geography: The Louisiana Barrier Islands
Barrier islands are long and narrow; built up by the action of waves and currents that protect the coast from erosion by surf and tidal surges. The islands are more common around the pacific coast of the United States. Large storms, such as hurricanes, can dramatically alter these islands. The waves generated by these storms erode the beaches even more strongly and carry the sand much further out where it will not return. One of the most prominent examples is the Louisiana barrier islands. They are eroding so quickly that according to some estimates they will disappear by the end of this century. The Missouri Alabama barrier islands are so dynamic and the magnitudes of their movement so great that changes in their positions and land areas

    New Jersey Sea Grant College Program Manual for Coastal Hazard Mitigation

    New Jersey is often used as an example of a natural system gone awry. The unflattering term "New Jerseyization" was coined by a prominent scientist to describe a developed, eroding coast, where natural beaches have been replaced by engineering structures. This view may have been correct in the past, when seawalls and bulkheads replaced many of our beaches, but our beaches are being brought back by artificial nourishment projects. Hard protection structures are only one phase in the cycle of changes on a developed coast. Human efforts can help regenerate landforms and biota, providing we take a proactive approach to shore protection that accommodates a wide range of resource values. The preferred method of shore protection in New Jersey has changed from groins, to bulkheads and seawalls, to beach nourishment. Hard protection structures are less likely to be built in the future, but many structures still exist, and some new structures may have local usefulness. Accordingly, it is important to know how these structures function. It is also important to know that all protection strategies have usefulness, but they are not readily interchangeable at a given location. Beach nourishment can help restore lost natural values, but many municipalities have elected to grade and rake their nourished beaches, preventing them from evolving into topographically and biologically diverse natural environments. The large amount of sand scheduled to be pumped onto New Jersey beaches in the future represents an invaluable resource, but the full potential of nourishment will not be realized without addressing habitat improvement and nature-based tourism in addition to the goals of protection from erosion and flooding and provision of recreation space. A dune is another valuable natural resource that is often overlooked. Dunes provide protection from flooding and…

    Summary Of Big Cypress And The Ten Thousand Islands

    Fresh water coming from Big Cypress Swamp combines with the Salt water in the Gulf of Mexico to create conditions that allow an amazing variety of life to flourish in features such as oyster bars, mangrove islands, tidal mud flats, and seagrass beds. While tidal mud flats and sea grass beds are important features the most prominent are the Oyster bars and Mangrove Islands. The Oyster bars and Mangroves are crucial in creating and continuing to develop the islands and characteristics that make up this region. Oyster Bars are formed by quartz sand carried by the current and deposited in deeper water parallel to the shore and eventually builds until it reaches the surface. If the conditions are right oysters colonize the sand deposits and the combination of oysters and sand create an oyster bar. Oyster bars gather nutrients by forming at right angles to tidal currents in order to catch nutrients from the incoming currents. Smaller branches form on the Oyster Bars and floating red mangrove seeds take hold in the sediments. Eventually multiple mangroves are caught and grow on the Oyster bar forming an island of roots and leaves. Overtime the mangroves arching prop roots will catch more sediment and the island will continue to develop eventually cutting off nutrients to the Oyster bar by restricting the currents that bring nutrients to the oysters. These structures help protect the region during storms, prevent erosion, and create Habitats for birds and fish. This is why more than 300 species of bird at some point are residents of the region as well as manatees and bottle-nose…

    Pensala Beach Research Paper

    The photo above was taken in Pensacola Beach, Florida in May 2017 at just about sunset at 7:23 PM. As you can see from the picture, there is very little beach left in Pensacola. One reason is linked to rising sea levels from global warming of the Earth’s climate system. New ocean water from melting reservoirs of ice could potentially raise the sea level as much as 3 feet by the year 2100 (Florida Oceans and Coastal Council). Increased water temperatures are also linked to increased hurricane activity, which has the potential to cause severe damage to the coastline. As you can see from picture 2, the beach area is much smaller after hurricane Ivan came through. Buildings damaged from hurricanes had to be relocated and replaced and others will…

    Martha’s Vineyard is a small island five miles off the southeastern shore of Massachusetts settled in the mid to late 17th century. For nearly 300 years, from the early eighteenth century to the mid twentieth century, it was home to a remarkably high percentage of deaf Americans who developed their own sign language, Martha’s Vineyard Sign Language. This isolated island allowed sign language to flourish beyond the deaf community, dissolving barriers between deaf and hearing prevalent in the rest of the world.…

    Everyone leaves a mark. It could be anywhere on anything on anyone. These marks can be big or small. They can affect anyone in a different way. And so, they make an impression, an impression that does not go away. For many people these “marks” were in the arts, because the culture was so embedded into the arts. And from these arts, whether it was a painting or a book, there were a so-called glow that engulfed the people of this time. They were left, intentional or not, for the people who desperately needed it. Since the 1700’s and on being desperate times for the people, and when these marks found them they created a new path. For many, they came from literary works, bringing comfort and hope. Although, there were a variety of writers that…

    Goldcoast Erosion

    In recent decades erosion has become a major issue to beaches around Australia, since beaches are temporary features. There is always sand being removed and sand being added to them, often, they change drastically during the year, depending upon the frequency of storms. Eventually, a beach erodes because the supply of sand to the beach cannot keep up with the loss of sand to the sea. The Sand dunes and vegetation help to hold the sand in place when wind or water tries to erode it away. The environment can be affected by erosion in several ways. First and the most obvious, houses that are built along the shore are at risk of being washed away if more sand is being removed from the beach in the winter, and not enough sand is returned in the summer. Secondly, animals that live on the beach are at risk for losing their homes. The amount of sand on the beach, and how it is deposited can also affect the shape of the shoreline, which can have an effect on the type of waves that are produced at the beach. The type of waves produced at the beach will also ultimately have an impact on beach erosion.…

    The Louisiana Purchase: The Expansion Of America

    Many opposed the growth of America and attempted to keep Americans boxed in east of the Mississippi River. Prior to becoming a part of America, the Louisiana Purchase was used as a tool to halt the expansion of the United States of America. Without the insight of Thomas Jefferson, the greed of Napoleon Bonaparte, and a Revolution in Sainte-Domingue the deal may never have happened. Thanks to these events America was able to almost double the amount of land that it owned and paved the way for expansion into the west.…

    Louisiana Purchase

    On April 30,1803 the Louisiana territory, which was a third of the land for the new nation we call America, was purchased from France for fifteen million dollars. This helped fund Napoleon’s war against Great Britain. Thomas Jefferson made this decision because Jefferson did not want any other nation ruling in that territory, because Jefferson did not want to feel threatened with natives from the new land and France trying to take over America. Another reason for this decision was because Congress pressed Jefferson to see if Jefferson wanted to either expand land or have other nations rule in the new mother land. After the purchase was done Thomas Jefferson had requested for the explore Merrieweather Lewis and asked Merrieweather Lewis to go explore the new land. Merrieweather Lewis received help from Sacagawea who translated to other tribes for food and trading Sacagawea taught Lewis and clark how to fish ,hunt and also how to grow crops, Sacagawea taught lewis and clark the basic skills to live off the land to make sure Lewis and Clark could survive off the land . Sacagawea also showed Lewis and Clark how to use other resources to make sure that Lewis and Clark stayed healthy and keep them safe from harm on the excursion through the dangerous native filled land. Sacagawea also showed Lewis and Clark the After Merrieweather Lewis and Clark came back, people started to move west and that is when the population started to grow. The Louisiana Purchase helped the nation grow not only in size but also in population and it helped us to gain new and stronger allies.…
