North Sentinel Island Case Study

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,

12. In the Figure 5 profile, the coastline is within a few kilometers of the western end of the vertical cross section. From the coastline, water depth increases very gradually to about 40 m at 140 km from shore (western end of the profile). This segment of the vertical cross-section resembles the continental [(rise)(slope)(shelf)]

North Stradbroke Island (NSI), also known as Minjerribah to its indigenous people, the Quandamooka people, is the second-largest island in the world, covering an area of 275.2 km2. The island has a wide range of ecosystems including open beaches, frontal dunes, rocky headlands, mangroves, and tidal swamps (Stradbrokeisland.com, 2018). On the island, the sand mining company, Sibelco, are to close their operation on NSI in 1919. This decision has been made through the exploration of advantages and disadvantages of undertaking sand mining on NSI, as well as alternative sources of economic income and planning replacement employment. When making the decision to close Sibelco’s sand mining on the island, it was important to remain mindful to the natives of the island and their ideals, traditions and sacred land. In considering all of these factors, it is most ideal for Sibelco’s sand mining operations on NSI to close.

We need to know if it is mountainous, flat, wooded, urban, rural, near water, near the ocean, heavily populated, whether it has a vulnerable population to the assigned risk, etc. Paint the class a word picture of the area where you live. Do not just tell us where it is.

2. Question : What is the most important single environmental factor in determining the productivity of rangelands?

First, I am going to talk about the importance of coral reefs. Coral reefs are some of the most diverse and valuable ecosystems on Earth. They are home to 4,000 species of fish, 800 species of hard coral, and hundreds of other species. Scientists believe that there are another 1 to 8 million unidentified species (NOAA). According to the National Oceanic and Atmospheric Administration, new drugs are being developed from

B) The afore mentioned estuary characteristic is more specifically called a lagoon. This means that it is a body of water separated from the ocean by barrier islands and because of this has limited exchange with the ocean through inlets. What makes the Indian River Lagoon so special is the fact that it is North America’s most diverse estuary. There are more than 2,200 different species of animals and 2,100 species of plants living within it.

(points 1) What is not one of the natural boundaries that define the South Asia subcontinent?

The climate of the Sunrise Islands is tropical, with warm temperatures all year long. Temperatures stay at 78—87°F throughout the year. Rain is at the lowest in January through March, at 3–4.5 inches, and highest in October, at around 11 inches. The daylight time is the same all year long, at 11.5 – 12.5 hr. per day.

Barrier Island is a low edge of sand that is parallel to the mainland with a distance of 2 to 19 miles’ off the shoreline, 300 barrier islands border the shore of Cape Cod, Massachusetts, to Padre Island, Texas. The barrier island defends the coast from the full power of storm waves. In the central of the barrier island and the mainland is a peaceful lagoon or a bay. Mainly most of these barrier island are 0.6-3 miles wide and amid from 9-18 miles long. The highest structures example of barrier island are sand dunes with the height of 16-33 feet; however, in some places the dunes can reach the height of 100 feet. Few barrier islands are initiated as spits that were then detached from the inland by upsurge corrosion, rising of sea level resulting

In just a few short decades, the island has lost over 90 percent of its landmass. Channels cut by companies to assist in oil and logging operations made the island more vulnerable to the effects of flooding and the assault of hurricanes and other storms. The result has been massive subsidence, saltwater intrusion, and land simply disappearing beneath the sea as sea levels rise due to global wrming.

The coral reef surveyors were instructed to find the best sites that they believed had the most living coral and were thought to be least affected by human activities. This would allow Hodgson to determine if human activities were having an appreciable effect on the supposed pristine coral reefs, which were distant from urban centers. The invertebrate survey was undertaken at two depth intervals of 3m and 10m. Four 0.5 m wide by 20 m long belts were placed on the coral reef. Over a period of 3-5 minutes the observers counted the number of invertebrates found on the belts. The coral survey was performed, by placing four 20 m long belts on the coral substrate. At 0.5 m intervals the substrate on which the belts were lying was examined and recorded.
