Global Warming & Sea Turtles Hotter sand from increasing temperatures results in decreased hatching rates or complete nest failure. Increased sand temperatures also affect hatchlings by altering natural sex ratios, with hotter temperatures producing more female hatchlings. Sea turtles use ocean currents to travel and find prey.Warming ocean temperatures influence migratory species by altering currents and impacting the distribution and abundance of prey species. This can result in southerly species being found in more northerly regions, well outside of their normal range.lobal Warming & Sea Turtles. The effects of global warming will have enormous impacts on sea turtles and other wildlife. The rate of global warming far exceeds the abilities of animals to adapt naturally to such dramatic environmental changes.

Finding Nemo Final Exam Project Leatherback turtles are regularly found much further north than other sea turtle species. As cold-blooded reptiles, a leatherback turtle’s body temperature should be the same as the temperature of the water, but they have been reported in water temperatures below 43°F.rabs and raccoons feed on the hatchlings when they first emerge out of their nest on the beach, and fish and seabirds are a threat to hatchlings in the water. Only sharks are large enough to prey upon adult sea turtles. Their flippers are especially vulnerable. Man is also a predator of the leatherback turtle.

- What causes ocean currents? Ocean currents result from two processes - the action of wind on the surface of the water, and from variation in water temperature that causes movement- a process known as convection. Convection occurs because the oceanic waters heat up becoming less dense.

How Ocean Currents Work The strongest tidal currents occur at or around the peak of high and low tides. When the tide is rising and the flow of the current is directed towards the shore, the tidal current is called the flood current, and when the tide is receding and the current is directed back out to sea, it is called the ebb current.his rise in water level is accompanied by a horizontal movement of water called the tidal current. Tidal currents differ from the currents previously mentioned in that they don't quite flow as a continuous stream. They also switch directions every time the tide transitions between high and low.

- Green Sea Turtle Sea turtles are graceful saltwater reptiles, well adapted to life in their marine world. With streamlined bodies and flipper -like limbs, they are graceful swimmers able to navigate across the oceans. When they are active, sea turtles must swim to the ocean surface to breathe every few minutes. When they are resting, they can remain un-derwater for much longer periods of time. How did the green turtle get its name? The green sea turtle gets its name from the green-colored fat tissue under its shell. The fat has a green color because the adult turtle’s diet consists of seagrass and algae. The Hawaiian name for the green turtle is Honu. What do they look like? Green sea turtles actually do not look very green from the outside.

Understanding the potential impacts of climate change on hawksbill turtle migration Some of these cues may be features of the ocean such as ocean currents and sea surface temperatures. It is important to understand how these features affect sea turtle movements so that we can predict if migration patterns might change in the future with climate change.ome of these cues may be features of the ocean such as ocean currents and sea surface temperatures.

Ocean current Deep ocean currents are driven by density and temperature gradients. Thermohaline circulation, also known as the ocean's conveyor belt, refers to the deep ocean density-driven ocean basin currents. These currents, which flow under the surface of the ocean and are thus hidden from immediate detection, are called submarine rivers.

- What causes ocean currents? Ocean currents result from two processes - the action of wind on the surface of the water, and from variation in water temperature that causes movement- a process known as convection. Convection occurs because the oceanic waters heat up becoming less dense. This water moves above the cooler water, and give off its heat to the surrounding environment. As it cools, it begins to sink, and the process begins again. Convection results in the continual circulation of ocean water on a global scale.

Ocean currents can be generated by wind, density differences in water masses caused by temperature and salinity variations, gravity, and events such as earthquakes. Surface currents are generated largely by wind. Their patterns are determined by wind direction, Coriolis forces from the Earth’s rotation, and the position of landforms that interact with the currents. Surface wind-driven currents generate upwelling currents in conjunction with landforms, creating deepwater currents.

The Atmosphere and Hydrosphere of the Earth Wind-driven Circulation. The main force driving the oceanic circulation is the wind. As wind blows across the sea-surface, part of the wind's momentum is transferred to the ocean, setting up currents. It is therefore clear that ocean currents should show a relationship with the global atmospheric circulation.

Currents Thermohaline Circulation. Winds drive ocean currents in the upper 100 meters of the ocean’s surface. However, ocean currents also flow thousands of meters below the surface. These deep-ocean currents are driven by differences in the water’s density, which is controlled by temperature (thermo) and salinity (haline).This process is known as thermohaline circulation.

Ocean Circulations The ultimate reason for the world's surface ocean currents is the sun. The heating of the earth by the sun has produced semi-permanent pressure centers near the surface. When wind blows over the ocean around these pressure centers, surface waves are generated by transferring some of the wind's energy, in the form of momentum, from the air to the water. This constant push on the surface of the ocean is the force that forms the surface currents. Learning Lesson: How it is Currently Done

Ocean current Ocean currents are similar to winds in the atmosphere in that they transfer significant amounts of heat from Earth’s equatorial areas to the poles and thus play important roles in determining the climates of coastal regions. In addition, ocean currents and atmospheric circulation influence one another.

Ocean Currents This heat is transported by ocean currents. In this way, the ocean currents help regulate Earth's climate by facilitating the transfer of heat from warm tropical areas to colder areas near the poles. The water of the ocean surface moves in a regular pattern called surface ocean currents. On this map, warm currents are shown in red and cold currents are shown in blue. Image Credit: Windows to the Universe. The global wind patterns cause the surface currents to form in the uppers layer of the ocean.

How Ocean Currents Work When speaking of water, the word current refers to the motion of the water. Currents are found in rivers, ponds, marshes and even swimming pools. Few bodies of water have the intricate system of currents that oceans do, though. Ranging from predictable tidal currents to fickle rip currents, ocean currents may be driven by tides, winds or differences in density. They profoundly affect the weather, marine transportation and the cycling of nutrients.

How Ocean Currents Work Tidal currents, as their name suggests, are generated by tides. Tides are essentially long, slow waves created by the gravitational pull of the moon, and to a lesser degree, the sun, on the earth's surface. Since the moon is so much closer to the earth than the sun, its pull has more influence on the tides.his rise in water level is accompanied by a horizontal movement of water called the tidal current. Tidal currents differ from the currents previously mentioned in that they don't quite flow as a continuous stream. They also switch directions every time the tide transitions between high and low.

Ocean current Depth contours, shoreline configurations, and interactions with other currents influence a current's direction and strength. Ocean currents flow for great distances, and together, create the global conveyor belt which plays a dominant role in determining the climate of many of the Earth ’s regions. More specifically, ocean currents influence the temperature of the regions through which they travel. For example, warm currents traveling along more temperate coasts increase the temperature of the area by warming the sea breezes that blow over them.
