how to remember arctic and antarctic

Did you know that arctic means "bear" and antacrtic means "no bear"? 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. (E. Siddon, UAF, Hidden Ocean 2005, NOAA.). We are going to plan a trip to … Your email address will not be published. Project 6633 generates new knowledge centered on Arctic and Antarctic security for the profession of arms. 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. To do so, pools of expertise need to be drawn together. Most of the Antarctic ice sheet is likely to thicken as a result of increased precipitation. 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. How big is the Arctic Circle? The Antarctic or the south-pole is what is below you. 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. A summertime channel carries melted ice to the sea. But in general, the knowledge we have on the Antarctic is very limited. We all know that we are sandwiched between two extremely cold regions in the north and in the south. The first thing to remember about how the Arctic and Antarctica differ is that one is a continent surrounded by ocean (Antarctica) and the other is ocean surrounded by land. And in turn, Arctic Cod are food for seabirds and many marine mammals. 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. In the Arctic, sea ice is also melting. To study ice, sometimes you have to break it. It has polluted and even destroys the life in it. 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. A female walrus and her calf (, (The Wales Inupiaq Sea Ice Dictionary, courtesy of Igor Krupnik (NMNH)). The Iñupiaq developed sophisticated survival skills for understanding animal migrations, weather patterns, ocean currents, and more. A large portion of narwhals lives in Baffin Bay, which is the body of water between the northeastern coast of Canada and Greenland. 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. Delen. • Arctic is the region on the top-most corner of the globe while Antarctic at the bottom most corner. Extremely cold temperatures, little sunlight and moisture, poor soil quality, and a short growing period have deterred most species of flora from successfully growing in this barren ecosystem. From Shishmaref to Sachs Harbour, Canada, Arctic communities are on the frontlines of climate change. Famous Igloo is one such example. 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. A narwhal is a toothed whale and is closely related to dolphins, porpoises, and orcas. Scientists also use ice cores to gain insight into the Earth’s ancient atmosphere. 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. 2 Fierce snow storms are called _____. The two landscapes however are made up in very different ways. Summers are still somewhat frozen (though, thanks to global warming, increasingly less so), but endlessly bright. The Arctic is an ocean, covered by a thin layer of perennial sea ice and surrounded by land. The famous tusk is actually a specialized tooth that protrudes out of the left lip, and in rare cases, a narwhal can have two. They can also use their tusks to break through the ice to create breathing holes. Weddell seals grind their teeth on holes in the ice to keep them open to their comings and goings between ocean and air. The mainstay of the Shishmaref diet is the bearded seal. Ice can be classified by age, whether it is made from fresh or salt water, or by its ever-changing forms. 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. From 1979 to 2005, sea ice cover declined by about 20 percent. They are also excellent at conserving oxygen—their muscles are built to minimize oxygen use and simultaneously can carry large amounts of oxygen. If fishing on a massive scale expands to the Ross Sea, the dynamic balance of this fragile ecosystem could fall apart. They eat the photosynthesizing phytoplankton and in turn are food for fish, seabirds and marine mammals. it also provides the information about different aspects like living isolation, empty location and arctic feasible , north pole etc. Unlike the Arctic, there are no indigenous communities based in Antarctica. (NMNH Anthropology Collections/Smithsonian Institution), (Screenshot from Smithsonian Alaska Native Collections), poles are actually more different than you might expect, communities of native peoples have thrived, scientists and technicians at isolated research stations, mostly scientists and technicians engaged in research, hundreds of names for the different kinds of ice, BBC crew filmed a never-before-seen phenomenon, found that the ice crystals don’t go away, different species among the pods in Antarctica, or at least subspecies, warming at twice the rate of the rest of the planet, sea ice cover declined by about 20 percent, discovered that the ratio of thick to thin sea ice is changing, Northwest Passage connecting Europe to Asia, the Antarctic, which is governed in part by a multinational treaty, already losing their shells in the Antarctic, Arctic region is home to more than 4 million people, residents of Shishmaref are working with the U.S. Government to relocate, world's finest anthropological collections from arctic and sub-arctic regions, ice-scratcher used by hunters to lure seals. This litter's parents (which are also up for auction!) This prevents temperatures in the Arctic regions from reaching the extremes typical of the land surface of Antarctica. 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. Remember these other important points around booking: Search engines and booking sites can be a convenient way to find flight deals. Affiliated to SOA, the Chinese Arctic and Antarctic Administration (CAA) is located in Beijing with about 40 permanent staff. This current pulls up cold, nutrient-rich waters from the deep sea to the surface, a process known as upwelling. The environments at the poles are some of the harshest on Earth—yet animals have found ways to survive there against the odds. Some animals make fantastically long migrations, moving from the Arctic to the Antarctic and back again every year, living an endless polar summer. I love reading about Arctic/Antarctic exploration. Polar bears are threatened by the loss of sea ice in the Arctic. 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. Ice can be classified by age, whether it is made from fresh or salt water, or by its ever-changing forms. A dive tender monitors the line connected to ice divers studying creatures living on the under-side of the sea ice. Large animals, like penguins, whales, and seals all feast on the krill. Both Arctic and Antarctic sea ice extent are characterized by fairly large variations from year to year. […] 20 Books About The Arctic and Antarctic (Must Reads For Cold Weather) - Voyage Love - […] Source by farawaylucy […] Submit a Comment Cancel reply. While details concerning the extent of future impacts of climate change are the subject of debate, the Arctic is experiencing those changes today. The Iñupiaq have lived in the northern section of Alaska for thousands of years. This cold, fresh water layer typically allows more ice growth in the Arctic than the Antarctic. Antarctica is almost entirely covered by ice sheets up to two miles (3 km) thick, which contain roughly 70% of the world’s freshwater. Right now, we see some human movement in the south but that is purely among the research facilities set up there. 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. We all know that we are sandwiched between two extremely cold regions in the north and in the south. You find polar bears in the Arctic but not in the Antarctic. All orcas are currently considered to be the same species, although there is some thought that they might be different species among the pods in Antarctica, or at least subspecies (pdf). Arctic Tern. The U.S. Coast Guard Cutter Healy is a ship with a primary mission to serve as a research platform in the Arctic. Because it is an ocean covered in floating parts of ice. In the absence of hemoglobin the gills of ice fish appear white. 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. The distance between the two polar regions is 20,117 kms (12,500 mi). This is in reference to the constellation, but it also applied to where polar bears live to make that easy to remember! 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). the lecture describes about arctic and Antarctic. This dense, salty water sinks and travels towards warmer tropical waters along the seafloor, forming part of the ocean’s great circulating “conveyer belt”. Right now, it is decreasing 12.8 percent each decade. 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 . Both poles carry some similarities but they are not at all the same. 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. From this thin layer, the ice becomes thicker and stronger, forming pack ice. 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. finding out all the places and not just the more immediately interesting ones such as the South Pole, islands, mountains and other features) and scientific investigation of Antarctica properly began with the International Geophysical Year (IGY) from July 1st 1957 to December 31st 1958. The Arctic Circle is made up of the Arctic Ocean and the North Pole, which is located in the centre of the circle. Unlike the north, it is a continent entirely surrounded by the ocean. it also provides the information about different aspects like living isolation, empty location and arctic feasible , north pole etc. Find out all about the Antarctic geography, wildlife and environment. How They’re Different. For people who live in the Arctic, weather and hunting grounds are becoming more unpredictable. The Arctic is what above you when you take a glob. Also, a belt of floating mass of ice debris called the ice pack surrounds the continent of Antarctica. Come March, the sun rises low in the Arctic horizon, and it won't set until six months later in September. 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. Fish have certain adaptations, like blood with built-in antifreeze, to survive in the Antarctic. If you were to stand at either pole, the view would be superficially very similar, there would be a great expanse of flat (ish) white snow and ice as far as the eye can see with few or no other features to break up the vista. Many different types of ice can be found in the Arctic and Antarctic. Skip to Content. The Arctic Ocean is characterized by a layer of cold, fresh water at its surface, a product of the floating ice. The Arctic and the Antarctic regions, however, are very different, with separate geopolitical and strategic considerations. The Arctic and Antarctic have kept our world in place for so long that it is our duty now to keep it that way. Aviaja Lyberth Hauptmann (Photo provided by Aviaja Lyberth Hauptmann) My name is Aviaja Lyberth Hauptmann. They have hollow guard hairs that keep fur from matting when it gets wet. Both the Arctic and Antarctic have plenty of ice and possess an intricate unique and ancient beauty. The fish actually have ice crystals inside their bodies and the special proteins ensure that the crystals don’t grow in size. Arctic Cod are critical players in the Arctic food web. It is an Ocean entirely surrounded by land. Early Eskimos, known as Groswater Dorset, occupied the Gulf of St. Lawrence about 2,500 years ago. Antarctic and … 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. The Arctic and Antarctic may be polar opposites, but in one sense they are connected despite being thousands of kilometres apart. Over the years, vast amounts of data have been collected about the Arctic and Antarctic ice. There is a small risk, however, that the West Antarctic and Greenland ice sheets will retreat in … She did her research with it and the poetry is fantastic. Both the Arctic and Antarctic are solid ice, with snow on top. The land entirely covered in ice with a thickness of about 1 mile. I was born in the capital of Greenland, Nuuk in ‘86 and grew up at the polar circle in the town Sisimiut. The researchers developed an algorithm that learns how to identify objects and patterns within the Arctic and Antarctic data. 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. Amidst the penguins and the seals, researchers look at everything from ecosystems underwater to ozone holes in the atmosphere. There is a large amount of variability in climate across the Arctic, but all regions experience extremes of solar radiation in both summer and winter. The Antarctic is also melting, albeit far slower, and in a less regular pattern. But to get on to the North Pole will need a boat. Another study published in the same year found that the rate of Antarctic ice melt has tripled in the last five years. There are some arctic artic jokes no one knows (to tell your friends) and to make you laugh out loud.Take your time to read those puns and riddles where you ask a question with answers, or where the setup is the punchline. COVID-19. In the Arctic, some of the sea ice stays throughout the year, called multi-year ice. For our final lesson in our polar animal unit, we sorted polar animals from the arctic and antarctic. The Arctic is usually defined by The Arctic Circle located at 66.5 degrees North, and the Antarctic is defined by the Antarctic Circle at 66.5 degrees south. Sea ice used to provide protection from powerful ocean waves but now that sea ice is melting, the shoreline is eroding rapidly. Then a film of ice forms, called grease ice, named for its close resemblance to the look of an oil slick on water. Required fields are marked *. Arctic and Antarctic Museum The dramatic story of Russian and Soviet polar exploration unfolds before visitors to this museum. Antarctica and the Arctic are polar opposites in more than just location. In certain regions of the Antarctic, sea ice cover is actually growing. The Plants of Antarctica. melting is expected on Arctic glaciers and the Greenland ice sheet, and they will retreat and thin close to their margins. The ice fish instead have special blood that contains proteins that act like antifreeze. Unicorns may be creatures of the imagination, but narwhals are the real deal. Diving is one of the narwhal’s special talents. 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. Both the Arctic Ocean and the Southern Ocean are defined by ice and dramatic shifts between endless day and endless night. They are some of the deepest diving whales with a record dive around 5,900 feet (1,800 meters)—over a mile deep! The graph is provided by the. But even is such temperatures there had been evidence that people lived in lad around that area for thousands of years. The increased global warming has taken its toll on the regions. Remember, the colours and in this case fur is all just speculation. They eat small crustaceans, such as amphipods and copepods. The temperatures are so extreme that no animal can survive except for the cutest of them all, the penguin.
