Antarctica is an unexplored world all its own, which is why it is a great place to conduct international science research.Antarctica’s most impressive characteristic is the giant ice sheet which covers almost all of the land. It also goes out hundreds of miles into the ocean in a few places.The largest ice shelf, called The Ross Shelf Ice, is as big as the entire state of Texas!Scientist have tracked the edge of the ice mass moving north at a speed of 1800 feet per year.
The continent houses ninety percent of the planet?s ice, and only two percent of the water.Sea level is kept in place because of the stability of the great inland ice.If it continues to melt, sea levels would rise visibly, and destroy seaports and alter coastlines.Contact this website if you require information on antarctica cruise review.
Complete melting would cause sea levels across the world to go up 250 feet.Not only scientists understand the vast importance of maintaining the ice shelf.If the ice is presently waxing greater or waning is not important.In theory, the great ice sheet is like a book of records for geophysical events that have occurred from this moment to as far back as a million years ago.
The ice and snow have recorded events like nuclear explosions, the use of leaded gasoline and even lead smelting.Measurements have been taken regarding the concentration of typical lead which precipitated over the surface of the ice during the prior 60 years.Because we have burned leaded gasoline, the decomposed lead alkyls have created an increase in the lead concentration on the surface of the ice, and these levels have been increasing steadily over the last ten years.Here it is maybe, that we will begin to understand the critical nature of the pollution challenges.
Some penguins, fish and seals from Antarctica showed traces of DDT, but the ice shelf itself did not.The planet is constantly being hit by stuff from space. These particles can be dated by where they are found in the ice.Scientist wonder if there are set patterns during which more particles hit the earth. If a pattern can be discerned, space travelers and vehicles could benefit from the information.For further insights on antarctica cruise vacations be sure to visit that site.
The majority of the flora are lichens in Antarctica.Land animals are found there, too. The most common are mites and springtails.No insects on Antarctica have flight capability; the biggest land animal is a wingless fly.In Antarctica?s waters, you?ll find the southernmost mammals. They are the Weddell seal and flightless penguin.The Weddell seal can stay underwater for thirty minutes and dive up to 1500 feet, amazing scientists.
Adelie penguins make their nests on ice-free spots on the coast of Antarctica and then head northward during the frigid winters.Innate biology, and the sun, allow them to draw a straight course for their next location.As a study, six of the Adelie penguins were released over 2,400 miles from their natural habitat and three of them found their way back within ten months.A few of them were taken by airplane to the South Pole and then let go.Once let go, they quickly found the sun?s location and set off on a straight course for home.
The richness of this area can also be seen in the huge creature that lives in its waters.The highly endangered blue whale is the largest animal ever recorded, and consumes a diet of a ton of shrimp on a daily basis.Antarctic waters house lots more species of fish than the Arctic does.A stunning proof of the efficiency of the Antarctic Convergence lies in the statistic that 90 percent of all bottom dwelling Antarctic fish can not be discovered anywhere else on earth.
