it also provides the information about different aspects like living isolation, empty location and arctic feasible , north pole etc. It is land ice that, as it melts, contributes to sea-level rise. Unlike the north, it is a continent entirely surrounded by the ocean. For people who live in the Arctic, weather and hunting grounds are becoming more unpredictable. In the Southern Ocean, Antarctic krill swim in dense schools of 20,000 animals per cubic yard (540,000 cubic feet). Unlike the Antarctic, which is governed in part by a multinational treaty, there is no treaty currently for the Arctic polar region. This imaginary circle is the southernmost latitude in the Northern Hemisphere where the sun can remain above or below the horizon for 24 hours (June 21st and December 21st). Smaller populations live off the eastern coast of Greenland as well. A recent report says the Arctic may be ice-free by 2040. Walruses forage on the seafloor, diving to depths up to 180 meters (590 feet) for clams, cockles, and mussels. The Arctic and Antarctic do look alike, however, in one important way: Glaciers in both places are losing lots of ice. Remember me. You could do that if you were a polar bear. Orcas communicate through a wide range of sounds, and each pod has an audio signature that members can recognize from far away. The researchers developed an algorithm that learns how to identify objects and patterns within the Arctic and Antarctic data. Second, remember that the Arctic is really a frozen ocean. So the Arctic Ocean has a layer of cold, fresh water near the surface with warmer, saltier water below. Even in the twenty-four-hour light of summer, the multi-year sea ice can be nearly 2 meters thick and the ship's job is to cut right through the ice, no matter its thickness. Both the Arctic and Antarctic are solid ice, with snow on top. Male narwhals will sometimes cross their tusks, a behavior called "tusking". They float with most of their mass below the water, hence the expression “tip of the iceberg”. the lecture describes about arctic and Antarctic. Many different types of ice can be found in the Arctic and Antarctic. The Smithsonian possesses one of the world's finest anthropological collections from arctic and sub-arctic regions. But researchers have also found that the ice crystals don’t go away during the warmer summer months—one of the implications of living below the ice. Emperors are the largest of all penguins—about half the height of adult humans. Orcas, also known as killer whales, can be found in both the Arctic and the Southern Oceans. Unlike the north, it is a continent entirely surrounded by the ocean. When salt water becomes ice, some of the salt is left behind in the water, making the water directly below sea ice saltier and denser than most seawater. It is an Ocean entirely surrounded by land. The Ross Sea, a 1.9 million square mile (3.6 million square km) stretch of ocean off the coast of Antarctica, has been nicknamed “The Last Ocean.” In 2008, researchers mapped out human impacts on the ocean globally and this small area of the Southern Ocean proved to be the most pristine piece of the ocean left on Earth. Meanwhile, the southern polar region has the opposite geography, with the huge landmass of Antarctica surrounded by the turbulent Southern Ocean. Glacial ice forms on land, and is made of freshwater snow packed down tightly over many years. Antarctic and … They are the largest of the dolphins, and powerful predators. This dense, salty water sinks and travels towards warmer tropical waters along the seafloor, forming part of the ocean’s great circulating “conveyer belt”. Weddell seals grind their teeth on holes in the ice to keep them open to their comings and goings between ocean and air. Unlike the Arctic, there are no indigenous communities based in Antarctica. The primary difference between the Arctic and Antarctica is geographical. Arctic Tern. But, further genetic testing proved that they were in fact, not the same species and that the miles between do make a difference. If you have to watch a little bit of discovery, I’m sure you are very familiar with the arctic. In keeping with this mandate, the Arctic Studies Center specifically studies northern peoples, exploring history, archaeology, social change and human lifestyles across the circumpolar world. Another simple difference to remember each by… the Arctic has Polar Bears and the Antarctic has Penguins! The Arctic and Antarctic Exercises 1 Complete the sentences with the words in the box. If you're fortunate enough to be planning a trip but don't know which to choose, here's our guide to the Arctic vs the Antarctic. Due to the fact that the Arctic is actually a frozen ocean, if you want to trek to the North Pole then you’d have to attempt it in the winter months. Swimming under the ice they can dive as deep as 700 meters (2296 feet) and attack prey, such as small fish, from below. This “brinicle,” as it is called, eventually reaches the sea floor where it covers the animals living there (like sea stars and urchins) in a layer of deadly ice. An ice-free Arctic also opens up possibilities for drilling for oil and gas. ), This graph of the Arctic sea ice coverage shows data from recent years. They inhabit the "fast ice"—sea ice that is attached to the shore. Antarctic and Arctic ice - Antarctic ice is predominantly annual. From the first days of polar navigation in the Russian Far North to the modern-day research stations in Antarctica, the breathtaking achievements of scientists and travelers are covered in great detail and illustrated with authentic artifacts. You find polar bears in the Arctic but not in the Antarctic. Aviaja Lyberth Hauptmann (Photo provided by Aviaja Lyberth Hauptmann) My name is Aviaja Lyberth Hauptmann. This is especially important now that humans are emitting carbon dioxide at an unprecedented rate (see Threats to the Poles section). The U.S. Coast Guard Cutter Healy is a ship with a primary mission to serve as a research platform in the Arctic. Introduction: I have always been extremely fascinated and curious about the two locations I chose to present for my final project :the Arctic and the Antarctic, also known as the North Pole and the South Pole. I am Kalaaleq (Inuk from Greenland), Danish, a microbiologist and a public debater. In oxygen-rich Antarctic waters, ice fish can withstand temperatures that would freeze the cells of other fish. They are some of the deepest diving whales with a record dive around 5,900 feet (1,800 meters)—over a mile deep! The Arctic is what above you when you take a glob. Both poles carry some similarities but they are not at all the same. I was born in the capital of Greenland, Nuuk in ‘86 and grew up at the polar circle in the town Sisimiut. The Arctic and Antarctic may be polar opposites, but in one sense they are connected despite being thousands of kilometres apart. Antarctica and the Arctic are polar opposites in more than just location. Variations in Extent. Key to survival is the skill with which they hunt arctic marine animals like seals and whales. They can swim for miles and stay submerged for two minutes at a time. • Antarctica is a continent surrounded by the world’s stormiest seas. The Arctic Ocean is characterized by a layer of cold, fresh water at its surface, a product of the floating ice. Your email address will not be published. These seals do not migrate and are commonly found within a few miles of their birthplace. The water in the ocean beneath it is warmer than the frozen ground in the Antarctic, and that warmth is transferred through the ice pack. More than 11,000 kilometers (6835 miles) separate the Arctic from the Southern Ocean. Antarctica is almost entirely covered by ice sheets up to two miles (3 km) thick, which contain roughly 70% of the world’s freshwater. You find polar bears in the Arctic but not in the Antarctic. You think it must be snowing all the time since it is soo cold. Although both are icy and frigid, the poles are actually more different than you might expect. The distance between the two polar regions is 20,117 kms (12,500 mi). The nutrients cultivate blooms of phytoplankton and ice-algae, which feed a super-abundant supply of Antarctic krill, small shrimp-like crustaceans. • Antarctica is a continent within Antarctic region. Contrasts between Antarctic and Arctic ozone depletion Susan Solomon*†, Robert W. Portmann*, and David W. J. Thompson‡ *Earth System Research Laboratory, National Oceanic and Atmospheric Administration, Boulder, CO 80305; and ‡Department of Atmospheric Sciences, Colorado State University, Fort Collins, CO 80523 Schrijf een review. Antarctica - Antarctica - Physical geography: The geologic evolution of Antarctica has followed a course similar to that of the other southern continents. It has polluted and even destroys the life in it. The environments at the poles are some of the harshest on Earth—yet animals have found ways to survive there against the odds. On the adjacent land, communities of native peoples have thrived for thousands of years by adapting to life along the edge of the ice. Then a film of ice forms, called grease ice, named for its close resemblance to the look of an oil slick on water. Save my name, email, and website in this browser for the next time I comment. The increased global warming has taken its toll on the regions. When sleeping and resting, Weddell seals may remain in the same spot for hours, melting a hollow in the ice underneath them with their own body heat. You can use this mini book, along with all the other printables, to consolidate the learning. In the Arctic, sea ice is also melting. This litter's parents (which are also up for auction!) These data are essential for scientists and policymakers seeking to … Then they dig out their prey using the tough edges of their noses, similar to how pigs root around in dirt and grass. it also provides the information about different aspects like living isolation, empty location and arctic feasible , north pole etc. Scientists are just beginning to understand who eats whom in the polar oceans. They use highly sensitive whiskers on their snouts to locate food. Remember, the colours and in this case fur is all just speculation. The Plants of Antarctica. What’s uncommon is its yearly migration, in which it travels from its Arctic breeding grounds to wintering grounds off the coast of Antarctica, some 25,000 miles away! Recent studies in the Ross Sea suggest the loud vocalizations may be used to stun prey. The planet’s polar regions, the Arctic and Antarctic, are both remarkably cold, which may explain why people often get them confused. To study ice, sometimes you have to break it. Atmospheric carbon dioxide has been rising for more than a century, with large contributions from the fossil fuels used to power our homes, businesses, and cars. Right now, residents of Shishmaref are working with the U.S. Government to relocate the entire village at a cost of $180 million. Arctic and Antarctic ice loss will account for about one-fifth of the warming that is projected to happen in the tropics, according to a new study led by Mark England, a … In both places the winters are frozen and devastatingly dark. When choosing polar destinations, Antarctica is often top of mind for many people but the Arctic offers distinct and incredible travel experiences. Three distinct types of killer whale can be found in the Antarctic, each with a different habitat and diet preference. Delen. Emperor penguins are the largest of the penguin species and can grow to be 100 pounds. But even is such temperatures there had been evidence that people lived in lad around that area for thousands of years. It is almost all about the Arctic and Antarctic, past and present, landscape and explorers. We are going to plan a trip to … Both Arctic and Antarctic sea ice extent are characterized by fairly large variations from year to year. Many northern communities have also observed coastal erosion and watched the permafrost—ground that used to be frozen all year—melting and buckling under their homes and roads. Early Eskimos, known as Groswater Dorset, occupied the Gulf of St. Lawrence about 2,500 years ago. […] 20 Books About The Arctic and Antarctic (Must Reads For Cold Weather) - Voyage Love - […] Source by farawaylucy […] Submit a Comment Cancel reply.

A polar bear and its cub in Arctic National Wildlife Refuge, Alaska. She did her research with it and the poetry is fantastic. A cold desolate continent covered in miles of ice and snow year-round, the south pole of … This cold, fresh water layer typically allows more ice growth in the Arctic than the Antarctic. Sea ice used to provide protection from powerful ocean waves but now that sea ice is melting, the shoreline is eroding rapidly. Among the hardiest of the polar creatures, the male emperor penguin is the only animal that remains throughout the winter on the Antarctic continent. Since the ice has disappeared the warmer, saltier Atlantic water is able to move northward. In 2011 a BBC crew filmed a never-before-seen phenomenon of the salt water sinking below newly formed ice and the water around it slowly freezing. Also, a belt of floating mass of ice debris called the ice pack surrounds the continent of Antarctica. The total area of perennial ice is barely 0.02 million km2 here, and two-year-olds - 2.4 million km2. Right now, it is decreasing 12.8 percent each decade. Following is our collection of Arctic jokes which are very funny. We all know that we are sandwiched between two extremely cold regions in the north and in the south. Like the Antarctic ice fish, they have an antifreeze protein that keeps their blood flowing. But the Arctic region is home to more than 4 million people, many of which are indigenous people, native to the area. Another study published in the same year found that the rate of Antarctic ice melt has tripled in the last five years. Warmer temperatures also cause sea level to rise and melt the permafrost, or frozen soil. Remember these other important points around booking: Search engines and booking sites can be a convenient way to find flight deals. come from the Arctic and Antarctic worlds, making their pups uniquely tied to both polar regions! Yet, the rainfall is so low, it is considered as a desert. Your email address will not be published. All QuillDogs of this litter are rated rare. McMurdo Station is the hub of the U.S. Antarctic Program. Small shelled creatures, like pteropods, which are important food sources for fish and larger animals, are already losing their shells in the Antarctic due to ocean acidification. Parts of these countries can also be found in the Arctic Circle: Russia, Canada, Alaska (USA), Iceland, Finland, Sweden, Norway and Greenland. The fish actually have ice crystals inside their bodies and the special proteins ensure that the crystals don’t grow in size. The Smithsonian's Arctic Studies Center, established in 1988, is the only U.S. government program with a special focus on northern cultural research and education. A 2018 study found that 10.7 percent of Antarctica's coastal glaciers are in retreat. Arriving at Arctic Watch Wilderness Lodge via charter flight from Yellowknife. That is Arctic is at the North pole and Antarctic at the South pole. The fish above are backlit by the ice above and easily spotted in silhouette. If you want to get beyond fiction/nonfiction, there is an amazing book of poetry by Elizabeth Bradfield called Approaching the Ice. There are roughly 172,000 of them swimming in the Arctic today. In years past, thicker ice was about 40 percent of total ice cover. The name arctic is originally originated from the Greek name, Arktikos meaning “of the north.Similarly, the Antarctic was named after Anrktikos meaning “opposite of the north”.But there are much easier ways to remember this than this Greek, literally. Some animals make fantastically long migrations, moving from the Arctic to the Antarctic and back again every year, living an endless polar summer. Because they are such strong swimmers, polar bears earned the species name of Ursus maritimus—bears of the sea. Did you know that arctic means "bear" and antacrtic means "no bear"? There is a small risk, however, that the West Antarctic and Greenland ice sheets will retreat in … They live and travel in pods that range in size from a few narwhals to several hundred individuals, but in the summertime, the congregations can be in the thousands. Polar bears are threatened by the loss of sea ice in the Arctic. To do so, pools of expertise need to be drawn together. Our team reached out to various academic, military, political, and NGO leaders to curate a collection of short responses to the question: What are the key challenges posed […] The sun-fed plankton are also important for the indigenous peoples of the Arctic who get food and clothing both from the sea (walrus, narwhals, beluga, other whales, polar bear, and fish) and the land (caribou, reindeer and musk-ox). And in turn, Arctic Cod are food for seabirds and many marine mammals. Antarctica and Greenland lose around 350 billion tons of ice each year from such melting. The male penguins huddle together and keep the egg warm by balancing it on their feet and covering it with their skin. They can also use their tusks to break through the ice to create breathing holes. This prevents temperatures in the Arctic regions from reaching the extremes typical of the land surface of Antarctica. and not shivering. Knowledge of the environment that has served generations is being defied by a changing climate. Arctic and Antarctic. Why it’s so amazing- cold weather adaptations It might not seem super special, but that fact that dinosaurs have been found in areas that used to have an Arctic-like climate is actually pretty ground-breaking.
