Sea turtles lay an average of about 100 eggs in each nest, and lay an average of 3-7 nests during their nesting season (Tim Flannery). Also in Florida, along about a twenty mile stretch of beach sea turtles lay over 150,000 pounds of eggs in the sand every nesting period. Which would seem like enough to keep their population up, but it is not that simple. Now why are sea turtle populations shrinking you may ask? Well, that’s simple. Climate change is not the only threat that a sea turtle has to fear. Along with climate change sea turtles face the fear of being eaten, not being able to make it back to the water when they are first hatched, being picked up by whatever or whoever may come by, and a whole other array of things that most do not even take into consideration. Over the last few years climate change has simply been one of the main things observed when
On the other hand, the geomagnetic storms have been intensified and enhanced in their frequency as magnetic fields of coronal mass ejections indulges with that of the earth that causes change of direction and leave more radiation and magnetic energy into the environment of the planet earth.

The data amassed by the scientist revealed that the Mid- Atlantic Ridge and the East Pacific Rise and countless other locations on the ocean floors display the same arrangements of varying magnetic stripes. As new volcanic rock erupts through fractures on the floor of the ocean, a progression identified as seafloor spreading, which causes the seafloor to widen (Trefil & Hazen, 2010). This new rock will be pushed aside as the continents are moved apart and as more magma comes up to take its place. The iron ore in this latest rock will steer to the position of the magnetic north pole once they get through to the top. Every occasion, that the planet’s magnetic field moves in the opposing direction, the dipole course of the planets magnetic field adjust and becomes encased in the recently constructed rock (Trefil & Hazen, 2010).
After reading The Earth on the Turtle’s Back and When Grizzlies Walked Upright, many key details are displayed about the Onondaga and Modoc cultures, these tribes vary in their beliefs but the morals that are conveyed through their folklore are very similar. In the story, The Earth on the Turtle’s Back, there is a group of mythical people that live in the Skyland. After the chief's wife dreams about the Great Tree being uprooted, the young chief pulled the tree from the soil, exposing a large hole in the ground, his wife leans to look into the hole and falls through to a sea of water, where the animals that inhabit it created Earth on the Turtle's back for her to live on. In When Grizzlies Walked Upright, the Chief Sky Spirit creates a mountain of snow and ice on Earth and
Our delicate eco-system is struggling to maintain it’s complex equilibrium. The precarious state of our oceans are largely attributed to the climate changes that are on going throughout earth. Along with consistently rising global temperatures come many devastating consequences. Our atmosphere is not the only aspect of our environment that is heating. Global warming is melting polar ice caps, raising water levels in our oceans, and releasing carbon that has been trapped in ice for thousands of years. The warmer air temperature is heating the surface waters of the ocean and creating more frequent and more powerful storms. These warmer surface waters are being pushed under in the ocean conveyor belt and the overall affect is a rise in overall ocean water temperatures. Climate change has been estimated to effect 88% of cetaceans and endangering nearly 21%. More specifically, each of these changes have harmful, potentially deadly and lasting effects on Bottlenose Dolphins. Ultimately causing dangerous and toxic conditions leading to an increase of dolphin strandings and death.
The climate change has caused not only waters to raise in temperature, but also in the sea level; this is having a major negative effect on sea turtles. When the female sea turtles lay their eggs and bury them in the sand, the rising waters make the eggs’ nest a dangerous place to be, resulting in even lower amounts of turtles hatched. Also, the rising temperatures effects the natural eggs’ incubation temperature of 34°C higher, which effects the sex of the turtle. Loggerhead turtles in Florida are ninety percent female due to this factor. If the temperature continues to rise, there may be no males left at all.
The following research project will focus on the Eastern Mediterranean Loggerhead Sea Turtle. Particularly, this paper will analyze why the Loggerhead consistently returns to it its natal nesting grounds in the eastern Mediterranean as opposed to nesting in the western region. To begin, background of the Eastern Mediterranean Loggerhead will be provided to the reader, and then the essay will proceed to discuss the process by which Loggerheads nest and hatch. Following this explanation, this essay will discuss this turtle’s transnational migration habits. After describing the movements of the animal, the reader will be provided with an analysis of possible reasons for natal homing. These reasons include: geographic and climate related preferences
The World Wildlife Organization states that, “Hawksbills help maintain the health of coral reefs. As they remove prey such as sponges from the reef's surface, they provide better access for reef fish to feed.” These turtles help take care of the reefs the fish we eat live in, without them fish would probably not have access to nearly as much food and would be eaten by prey on the surface of the reef. Sea life getting stuck in fishing nets has been a problem in the past, so minimizing that too would be ideal.
Magnetism occurs when a magnetic field forms. There are two sides of a magnetic field; south pole and north pole. If the two poles are opposite, they will attract and vise versa. A magnet can magnetize an iron object. Electromagnetic waves work
Light pollution has become a problem for sea turtle hatchlings along developed coastlines. The hatchlings have a natural instinct to move to the brightest direction which on a naturally lit beach is the night sky over the ocean. However, the artificial light that is found on developed coastlines, disorients sea turtle hatchlings and as a result they move towards this light instead of the ocean. According to an article on conserveturtles.org, only 1 in 1000 sea turtle hatchlings survive to maturity therefore changing artificial lighting practices on beaches would help the sea turtle population. The implementation and enforcement of artificial light ordinances for coastal homeowners would be a solution to the effects of light pollution
Reviews provided by top organization, Intergovernmental Panel on Climate Change indicate that climate change is likely to induce changes in temperatures and adjustment associated with ocean circulation, sea level, and ice coverage. Impact of climate change on marine mammals occur differently according to type of mammal and its dwelling place either deep-sea dweller or surface sea dwellers (Aguirre, Ostfeld, & Daszak, 2012). Marine species distribution is affected by multiple factors; ecological, habitat related and anthropogenic factors. Habitat distributed
The topic argues about a dangerous problem to some particular turtle's species. It is described as when fishers want to fish, turtles get stuck in their net.The problem is, turtles get trapped into these nets so they cannot come to the surface for breathing air, eventually they'd die.
Earth is in fact an intricate planet that has multiple layers of differing compositions. To be exact the earth has four main layers. The uppermost layer is the one humans come in most contact with, the crust. The crust consists of “thin silicate rock material”(Structure of the). Although the crust is not entirely the same. Actually there are two distinct types of crust, oceanic and continental. “The continental crust is made up of mostly rocks similar to granite while the oceanic crust is much denser and made up of a material similar to basalt”(Structure of the, Rose). The second layer is called the mantle. “The mantle is much denser than the crust and contains similar to the crust mostly solid silicate crust”(Structure of the). “As we travel further down the earth we wind up in the outer core. The outer core is a core of molten nickel and iron. Finally there’s the inner core. The inner is a solid metal core made up of nickel and iron”(Structure of the). All these layers functioning together cast out a magnetic
