arctic and antarctic

International Scientific Conference "COMPREHENSIVE RESEARCH OF THE NATURAL ENVIRONMENT OF THE ARCTIC AND ANTARCTICA", March 2 . The Arctic Ocean is characterized by a layer of cold, fresh water at its surface, a product of the floating ice. Some areas of the Arctic Ocean, like the Barent Sea north of Scandinavia, are warming so quickly that they are being taken over by Atlantic waters. Both male and female walruses have strong long tusks that they use to help pull themselves out of the water. Scientists have discovered that the ratio of thick to thin sea ice is changing. This current pulls up cold, nutrient-rich waters from the deep sea to the surface, a process known as upwelling. It is interesting to note that the Arctic region was found long before the Antarctic region was found. The collection at the Smithsonian preserves thousands of artifacts from the Iñupiaq culture, including parkas made from caribou, a mask worn by a woman dancer, and an ice-scratcher used by hunters to lure seals. The Antarctic is characterized by the blowing of strong winds. Since the ice has disappeared the warmer, saltier Atlantic water is able to move northward. A dive tender monitors the line connected to ice divers studying creatures living on the under-side of the sea ice. They inhabit the "fast ice"—sea ice that is attached to the shore. China in the Arctic and Antarctic: A Threat? It is true that there are no bears in Antarctica, but the name comes from a Roman version of the Greek word that is antarktike. • However, the Antarctic region is qualified by the presence of marine mammals such as penguins, whales and seals. A 2018 study found that 10.7 percent of Antarctica's coastal glaciers are in retreat. Compare the Difference Between Similar Terms. Polar Bears are dying off. When ice sheets grow and move out over the ocean they form ice shelves. Now it's down to just 10 percent and the Arctic may have ice-free summers by the end of the 21st century. They can swim for miles and stay submerged for two minutes at a time. Thus, Antarctica means opposite of Arctic land, “Anti-” plus the Arctic which forms a compound word. Fish have certain adaptations, like blood with built-in antifreeze, to survive in the Antarctic. An ice-free Arctic could mean a new trade route—a Northwest Passage connecting Europe to Asia - bypassing both the Panama and Suez canals. It is land ice that, as it melts, contributes to sea-level rise. Some animals make fantastically long migrations, moving from the Arctic to the Antarctic and back again every year, living an endless polar summer. Also, while the Antarctic region is covered with snow all thorough the year, the Arctic lands generally have a summer, free from ice and snow. This explosion of life supports the entire food web for the whole year—from soft corals on the seafloor to the arctic foxes on the ice. So scientists thought only a few species would live in both places until researchers taking part in the Census of Marine Life found over 200 species that appeared to live in both polar seas, including cold-water worms, crustaceans, sea cucumbers and pteropod snails.

This Webby award-winning video collection exists to help teachers, librarians, and families spark kid wonder and curiosity. In both regions freezing temperatures, ice, snow and the darkness of the long polar nights make it difficult for plants, animals and humans to survive. Diving is one of the narwhal’s special talents. Emperor penguins are the largest of the penguin species and can grow to be 100 pounds. These seals do not migrate and are commonly found within a few miles of their birthplace. The graph is provided by the. It's warming at twice the rate of the rest of the planet. 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. This is the reason why the Antarctic region is considered colder and windier than the Arctic region. Antarctica is isolated from the rest of the continents by the Circumpolar Current, which swirls clockwise around the landmass. Unlike the Antarctic, which is governed in part by a multinational treaty, there is no treaty currently for the Arctic polar region. In the Arctic Ocean, different species of copepods have different life cycles and eating patterns and they are important sources of food for larger organisms. The sea-ice closer to land and attached to the shoreline is called fast ice (short for fastened). They are some of the deepest diving whales with a record dive around 5,900 feet (1,800 meters)—over a mile deep! The ice caps are melting and sea levels are rising because of the warming of our planet due to greenhouse (R. Hopcroft, UAF, Hidden Ocean 2005 NOAA. The Arctic region is also characterized by the presence of trees such as Tundra and flowering plants. The Arctic and Antarctic are the two most geographically distant bioregions on earth. In an amazing feat of synchronized swimming, they use a staggered formation so that no krill swims directly in another's wake. Depending on the season, much or all of the Arctic Ocean is covered by a layer of sea ice, ranging in thickness from a few inches to over six feet, which is always shifting as it floats on the ocean's surface. The Arctic consists of the Arctic Ocean, adjacent seas, and parts of Alaska (United States), Northern Canada (Canada), … Amidst the penguins and the seals, researchers look at everything from ecosystems underwater to ozone holes in the atmosphere. The fish above are backlit by the ice above and easily spotted in silhouette. Difference Between Longitude and Latitude, Difference Between Coronavirus and Cold Symptoms, Difference Between Coronavirus and Influenza, Difference Between Coronavirus and Covid 19, Difference Between Works Cited and Works Consulted, Difference Between Stereotype and Archetype, Difference Between Imidazolidinyl Urea and Diazolidinyl Urea, Difference Between Chlamydomonas and Spirogyra, Difference Between Borax and Boric Powder, Difference Between Conditional and Constitutive Knockout. Difference between Antarctic and Arctic Key Difference: The most obvious difference between Antarctic and Arctic is that Antarctic is located in the southern hemisphere and encompasses the South Pole region, whereas Arctic is located in the northern hemisphere and encompasses the North Pole region. The Arctic and the Antarctic show differences in their environment, weather, animal and plant life, human activity, and the like. The Antarctic region has no trees too. For comparison, this is 10.7 °C (20 °F) colder than subliming dry iceat one atmosphere of partial pressure, but since CO2 only makes up 0.039% of air, temperatures of less than −140 °C (−220 °F) would be needed to produce dry ice snow in … This list covers everything, from classics like Animales Polares En Peligro =: Polar Animals in Danger to popular sellers like The Golden Compass to some of our favorite hidden gems like Tacky the Penguin. and not shivering. In certain regions of the Antarctic, sea ice cover is actually growing. During this bright period, Arctic algae and phytoplankton kick into overdrive, using photosynthesis to use the 24-hour sunlight to make food. From Shishmaref to Sachs Harbour, Canada, Arctic communities are on the frontlines of climate change. Recent sampling efforts and following metagenomics have shed light on the global ocean microbial diversity and function, yet the microbiota of polar regions has not been included in such global analyses. Large animals, like penguins, whales, and seals all feast on the krill. A female walrus and her calf (, (The Wales Inupiaq Sea Ice Dictionary, courtesy of Igor Krupnik (NMNH)). Russia has already staked a claim, using submarines to plant a flag on the Arctic Ocean floor. Ironically, the ships that bring nature-loving tourists may also unwittingly be bringing invasive species, such as plant spores and rodents that could damage the fragile Antarctic ecosystem. When it comes to children’s stories about arctic and antarctic, there are a variety of titles. Sea ice is by definition made from frozen seawater, which gives it different properties than ice made of freshwater. But the Arctic region is home to more than 4 million people, many of which are indigenous people, native to the area. “Anti-” is commonly a synonym for the opposite in English as well as in Greek. The ice fish instead have special blood that contains proteins that act like antifreeze. All rights reserved. Next: More arctic and more Antarctica, including Science and survival on Continent 7 and Drifting With the Ice: Life on an Arctic Expedition. Antarctica is the coldest of Earth's continents. But, overall the land- and fresh-water based ice continues to shrink. @media (max-width: 1171px) { .sidead300 { margin-left: -20px; } } 66º33′ are the northern and southern latitudinal lines of the Arctic Circle (66º33′ N) and Antarctic Circle (66º33′ S), respectively. Many different types of ice can be found in the Arctic and Antarctic. Other than polar bears, there are other marine mammals such as whales, seals and walrus in the artic. While details concerning the extent of future impacts of climate change are the subject of debate, the Arctic is experiencing those changes today. Antarctic and Arctic are two regions on Earth. A polar bear and its cub in Arctic National Wildlife Refuge, Alaska. Travel to the ends of the earth—literally—and discover the polar ocean basins. 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. (E. Siddon, UAF, Hidden Ocean 2005, NOAA). Due to the lack of major population centres in the Arctic, weather and climate observations from the region tend to be widely spaced and of short duration compared to the midlatitudes and tropics. The Arctic and Antarctic may be polar opposites, but in one sense they are connected despite being thousands of kilometres apart. The first difference between the Arctic and Antarctica is they’re located on opposite sides of the world. Since 1955, scientists have been coming to McMurdo primarily in the southern 'summer' months of October to February. Land is being lost, along with animals that provide food for the people living in the Arctic. 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. Sea ice differs between the Arctic and Antarctic, primarily because of their different geography. A narwhal breaching the water's surface, his tusk points to the sky. Antarctica, by contrast, is an entire … Arctic Cod are critical players in the Arctic food web. Though the Vikings explored parts of the Arctic over a millennium ago, and small numbers of people have been living along the Arctic coast for much longer, scientific knowledge about the region was slow to develop; the large islands of Severnaya Zemlya, just north of the Taymyr Peninsula on the Russian mainland, wer… And in turn, Arctic Cod are food for seabirds and many marine mammals. From 1979 to 2005, sea ice cover declined by about 20 percent. The Arctic ( or ) is a polar region located at the northernmost part of Earth. Today their lands are part of four different nations—the United States, Canada, Denmark (Greenland) and Russia. That is Arctic is at the North pole and Antarctic at the South pole. Sea ice forms during the winter, more than doubling the size of the Antarctic continent, and then melts in the spring and summer. The Arctic is not the Antarctic and the Antarctic is not the Arctic.” Antarctica is surrounded by the vast Southern Ocean, which is soaking up much of the atmosphere’s excess heat. Also, the region is devoid of masses of algae. Among the biggest threats to the poles is rapid climate change. The ice has trapped bubbles, salts, and sediments that can help tell the story of how the climate has changed. When it comes to animal behavior, you would find fierce animals in the Arctic region. The Arctic is largely sea, with the north pole over 400 miles away from the nearest land mass. Since the signing of the Antarctic Treaty in 1959, the southern polar region has been managed on a collective basis. In the northern polar region, the water and ice of the Arctic Ocean are surrounded by land. On the adjacent land, communities of native peoples have thrived for thousands of years by adapting to life along the edge of the ice. Its formation begins in very cold water surrounded by thicker sea ice or land with a slushy mix of water and ice crystals on the sea surface, called frazil ice. More than 11,000 kilometers (6835 miles) separate the Arctic from the Southern Ocean. 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. Floes are more prone to converge, or bump into each other, and pile up into thick ridges… To study ice, sometimes you have to break it. But, further genetic testing proved that they were in fact, not the same species and that the miles between do make a difference. They float with most of their mass below the water, hence the expression “tip of the iceberg”. Here a metagenomic study of seawater samples (n = 60) collected from different depths at 28 … 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. They have hollow guard hairs that keep fur from matting when it gets wet. Simply tell us if you think the answer is the Arctic, Antarctica, or perhaps even both… You could do that if you were a polar bear. Unicorns may be creatures of the imagination, but narwhals are the real deal. While the Arctic region has … In the northern polar region, the water and ice of the Arctic Ocean are surrounded by land. Weddell seals are very vocal and have a large repertoire of sounds. The Iñupiaq developed sophisticated survival skills for understanding animal migrations, weather patterns, ocean currents, and more. Orcas, also known as killer whales, can be found in both the Arctic and the Southern Oceans. That way they avoid turbulence. Imagine it being 40 degrees below zero (Fahrenheit and Celsius are equal at this temperature!) That’s because the Arctic (north pole area) is melting. It is devoid of towns and living places. The Greenland and Antarctic ice sheets are the only ice sheets currently on Earth, and they contain 75 percent of the freshwater in the world. Glaciers and icebergs represent two of the most important facets of Earth's ecosystem. Ice can be classified by age, whether it is made from fresh or salt water, or by its ever-changing forms. The Arctic is an ocean, covered by a thin layer of perennial sea ice and surrounded by land. This dense, salty water sinks and travels towards warmer tropical waters along the seafloor, forming part of the ocean’s great circulating “conveyer belt”. • The Arctic has indigenous people such as Inuits, Indians and Siberians, but Antarctic remains unpopulated. The Arctic is characterized by the blowing of mild winds. Recent studies in the Ross Sea suggest the loud vocalizations may be used to stun prey. In oxygen-rich Antarctic waters, ice fish can withstand temperatures that would freeze the cells of other fish. Meanwhile, the southern polar region has the opposite geography, with the huge landmass of Antarctica surrounded by the turbulent Southern Ocean. A stormy sea lashes the village of Shismaref, Alaska, where the coastline has eroded 30–90 m (100–300 ft) in the past 30 years. Come March, the sun rises low in the Arctic horizon, and it won't set until six months later in September. Without phytoplankton and algae, the large marine animals would not have food to eat. Global temperatures have increased since the 1800s, and sea ice has been decreasing in extent and thickness. Nowadays, scientists have impermanent camps in Antarctic. Scientists are just beginning to understand who eats whom in the polar oceans. 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. Antarctica and Greenland lose around 350 billion tons of ice each year from such melting. And climate scientists predict that before long, there will be no ice left. 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. Another study published in the same year found that the rate of Antarctic ice melt has tripled in the last five years. Antarctica is covered by ice throughout the year, less than 5% of Antarctica is free of ice. The dark sea floor of the Antarctic, beneath sea ice, is covered with life. The Arctic Studies Center seeks to bring its researchers together with community scholars in the collaborative exploration of the cultural heritage represented in these impressive collections. There are roughly 172,000 of them swimming in the Arctic today. Depending on the season, much or all of the Arctic Ocean is covered by a layer of sea ice, ranging in thickness from a few inches to over six feet, which is always shifting as it … International Scientific Conference "COMPREHENSIVE RESEARCH OF THE NATURAL ENVIRONMENT OF THE ARCTIC AND ANTARCTICA", March 2 ), This graph of the Arctic sea ice coverage shows data from recent years. A view of McMurdo Station with a frozen Ross Sea in the background. In sum, comparing the Arctic and Antarctic when analyzing political and institutional issues leads to the all-to-common apple-and-pear comparison. Although both are icy and frigid, the poles are actually more different than you might expect. 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). The environments at the poles are some of the harshest on Earth—yet animals have found ways to survive there against the odds. Sea ice used to provide protection from powerful ocean waves but now that sea ice is melting, the shoreline is eroding rapidly. Before Antarctica officially acquired its name, the phrase was used to describe places that contrasted the north. Because they are such strong swimmers, polar bears earned the species name of Ursus maritimus—bears of the sea. For thousands of years, the people in the Arctic have adapted to living in an ice-bound environment. 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. Seen here is a Dorset point made of Ramah Chert that was recovered at Hare Harbor. The Arctic and Antarctic – two fundamentally different polar regions The north and south polar regions are among the most remote and extreme environments for life on Earth. And it is not just temperatures that are changing due to the increases in carbon dioxide. However, nowadays, scientists have impermanent camps in Antarctic. These increasing concentrations of greenhouse gases are trapping heat and taking a toll on the planet, especially at the poles where the largest increases in temperature will occur. Flora. From giant glaciers to thin pack ice, each has distinctive characteristics, and those who have spent time in the Poles, from native people to sailors, have hundreds of names for the different kinds of ice. For instance, in the 16th century, the colony that was built … They take turns moving into the center of the crowd to warm up and then trading places with a penguin on the cold perimeter. Few cross these lines for any reason, though today more are doing so under the pretext of defense and security. It has indigenous people such as Inuits, Indians and Siberians. • Antarctica is a continent surrounded by the world’s stormiest seas. It has the longest migration of all birds, flying from breeding grounds near the North Pole to wintering grounds off Antarctica. This is one of the main reasons why climate fearmongers prefer to focus on the Arctic rather than the Antarctic in their doomsday lectures and discourses. Orcas stay put in their distinctive ecosystems, and there are different characteristics of the groups (or pods) in various locations. While all males have a tusk, only 15 percent of females have a tusk, leading scientists to believe it has a role in sexual selection. Antarctica means 'no bears are all mythical'. Male narwhals will sometimes cross their tusks, a behavior called "tusking". They are also excellent at conserving oxygen—their muscles are built to minimize oxygen use and simultaneously can carry large amounts of oxygen. Arctic and Antarctic glaciers, icebergs, and other ice trivia. Orcas travel in pods of up to 40 related individuals. McMurdo Station is the hub of the U.S. Antarctic Program. A belt of floating mass of ice debris called the ice pack surrounds the continent of Antarctica. The fish actually have ice crystals inside their bodies and the special proteins ensure that the crystals don’t grow in size. Icebergs are formed when chunks of glacial ice break off (called calving) from an ice sheet or shelf. The male penguins huddle together and keep the egg warm by balancing it on their feet and covering it with their skin. That might not seem like much, but keep in mind it includes all the saltwater in the oceans too. It does not have indigenous people nor have any large land animals. If fishing on a massive scale expands to the Ross Sea, the dynamic balance of this fragile ecosystem could fall apart. That is Arctic is at the North pole and Antarctic at the South pole. Industrial fishing, started in 1996 by New Zealand and now practiced by a dozen nations, is homing in on Antarctic toothfish and krill in the Ross Sea. Filed Under: Earth Tagged With: Antarctic, Arctic, arctic and antarctic, Continent, Eskimos, Igloos, Penguins, Polar bears, seals, Koshal is a graduate in Language Studies with a Master's Degree in Linguistics. The Arctic is a semi-enclosed ocean, almost completely surrounded by land. When you look at the globe, Arctic is the region on the top-most corner of the world. 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. In fact, polar bears are more concerned about overheating than about getting cold. In years past, thicker ice was about 40 percent of total ice cover. Current Arctic sea ice extent Arctic sea ice extent on 9 th August was 5.60 million square km, 1.87 million square km below the 1981-2010 average. Scientists also use ice cores to gain insight into the Earth’s ancient atmosphere. Both regions have attracted their fair share of explorers in search of glory, scientific and … The female penguins leave the males to protect their one egg and cope with wind chill temperatures of -60°C (-76°F). The Southern Ocean has also become a draw for ecotourists who seek to visit places where humans are far outnumbered by penguins. Also, a belt of floating mass of ice debris called the ice pack surrounds the continent of Antarctica. Understanding the function of the tusk is an ongoing area of investigation. The symbol of the Arctic is often the polar bear, the pole's cute yet fearsome top predator. Polar bears have two layers of fur, plus a layer of blubber to keep them warm in the coldest weather, and black skin to absorb the heat. As a result, the sea ice that forms in the Arctic is not as mobile as sea ice in the Antarctic. The longest tusks can reach over eight feet long (2.4 meters). Explorers. Antarctica, on the other hand, is a continent, covered by a very thick ice cap and surrounded by a rim of sea ice and the Southern Ocean. Without sea ice, hunting has become significantly harder. Both the Arctic Ocean and the Southern Ocean are defined by ice and dramatic shifts between endless day and endless night. … • Arctic is the region on the top-most corner of the globe while Antarctic at the bottom most corner. 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. Arctic and Antarctic differ a lot when it comes to the human activity and animal and plant life existent on them. Antarctica is mostly an ice sheet, with the south pole located some 800 miles from the sea. Animals found on the Antarctic region are calm in nature. Key to survival is the skill with which they hunt arctic marine animals like seals and whales. The nutrients cultivate blooms of phytoplankton and ice-algae, which feed a super-abundant supply of Antarctic krill, small shrimp-like crustaceans. The mainstay of the Shishmaref diet is the bearded seal. The indigenous people of the region encircling the North Pole are known by many names—Inuit, Eskimo, Kalaadit. But, masses of algae can be found in the Antarctic region. Antarctica is the coldest, driest, and windiest of Earth's seven continents, and 98 percent of the continent is covered by ice with no tundra, trees or bushes. 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. ADVERTISEMENT. • Arctic area has trees while Antarctic does not. A narwhal is a toothed whale and is closely related to dolphins, porpoises, and orcas. When uneaten organisms die, they sink to the seafloor, feeding fish, seastars, soft corals, and other organisms in deeper water. Three distinct types of killer whale can be found in the Antarctic, each with a different habitat and diet preference. Great description; It is a good idea to put images to complement the description. This quiz couldn’t be more straightforward. Traveling at such depths where there is intense pressure requires a few special adaptations, including a compressible rib cage and streamlined body. • Arctic has a large range of marine and terrestrial animals such as whales, polar bears, wolves, etc., but Antarctic does not have any large land animals. Emperors are the largest of all penguins—about half the height of adult humans. Antarctica is the earth’s southernmost and fifth-largest continent, dividing the southern waters of the Pacific and Atlantic oceans. Unlike the Arctic, there are no indigenous communities based in Antarctica. The Arctic is not as cold as the Antarctic for two main reasons, firstly the effect of the sea that doesn't fall below -2°C which means that the whole of the arctic polar region and coastal regions are kept relatively warm even though the sea is covered by ice. The Arctic is a region of shared resources and ecosystems with a complex institutional system and actors. All but one or two percent of Antarctic land is covered by glaciers, some of which are more than 15,000 feet (4,700 meters) thick. Polar bears, who rely on sea ice to reach seals for their winter meals, will have less time to reach their food source as the ice declines and breaks up earlier in the season. Then they dig out their prey using the tough edges of their noses, similar to how pigs root around in dirt and grass. Although sea ice moves around the Arctic basin, it tends to stay in the cold Arctic waters. Pack ice is also referred to as drift ice because it is not attached to a shoreline and can be moved by the wind and ocean currents. Polar bears are threatened by the loss of sea ice in the Arctic. 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. The Arctic Tern could really be called the Arctic-Antarctic Tern. A region with vaguely defined limits, it extends over six countries that border the Arctic Ocean: Canada, the USA (Alaska), Denmark (Greenland), Russia, Norway and Iceland. Antarctica is almost entirely covered by ice sheets up to two miles (3 km) thick, which contain roughly 70% of the world’s freshwater. Though both are snow filled areas, there is a difference between Arctic and Antarctic. The lowest natural air temperature ever recorded on Earth was −89.2 °C (−128.6 °F) at the Russian Vostok Station in Antarctica on 21 July 1983. Arctic and Antarctic sea-ice extent are both projected to dramatically decline over the coming century. Glaciers, icebergs and ice sheets are all formed from glacial ice. They use highly sensitive whiskers on their snouts to locate food. But, the Antarctic region is qualified by the presence of marine mammals such as penguins, whales and seals. Subsistence hunting of bowhead whales formed the basis for Iñupiaq social and spiritual life. In the winter narwhals live offshore among the ice floes, but in the summer, when the ice melts, they migrate towards the shore and congregate in summering grounds. Yet the two regions are also fundamentally different from one another. What keeps this marine ecosystem going are organisms you can't see with the naked eye: microscopic phytoplankton and ice algae. Arctic Cod can live in water that is cooler than the freezing point of blood. Antarctica is a continent devoid of human settlement, except for the over 50 research stations built there by 27 different countries.
