Sea ice Essays

Polar bears are the largest land carnivores in the world. Polar bears are marine mammals, and spend much of their time on Arctic sea ice. Many adaptations make polar bears uniquely suited to life in icy habitats and Polar bears feed almost exclusively on ringed seals and bearded seals. They are also known to eat walrus, beluga whale and bowhead whale carcasses, birds’ eggs, and (rarely) vegetation. Polar bears travel great distances in search of prey. (defender,2017). Polar bears succeed in catching

Imagine a world with no Arctic ice cap, no Arctic animals, and no Arctic ecosystem. Climate change, which is also known as global warming, is taking a toll on the Arctic ecosystem and endangering many different animal species and wildlife living in the Arctic. To understand why the Arctic animals as well as the Arctic ecosystem is threatened, an understanding of climate change is needed. By definition, climate change is the rise in average surface temperatures on Earth, mainly due to the burning

Polar bears skin is good for many reasons. Another fact is that Polar bears grow hairs on the bottom of their paws so that when they are talking around on ice they don’t get as cold. According to SeaWorld,”The sole of a polar bear 's foot has thick, black pads covered with small, soft papillae. The papillae create friction between the foot and ice to prevent slipping. Long hairs growing between pads and toes also help prevent slipping”(www.seaworld.com). What this says that polar bears paws are very

Evolution of polar bears Polar bears have very interesting history, they evolved from bears. Polar bears have black skin but there fur is white because they adapted to the arctic ocean. They use the sea ice to platform to hunt their prey. They hunt seals for prey. They have 45 teeth that help them tear seals skin. Polar Bears have adapted to their environment by many reasons. The main reason is by their fur because they have thick oily fur coat. They also have have a layer of fat under their skin

become endangered or go extinct. Humans do a lot of bad things, that cause many species to go extinct or become endangered. One of the biggest problems is human predation. Humans do a lot of harm by hunting. They erased the megafauna mammals of the last Ice Age, decreased the population of whales and other marine mammals, and wiped out the Dodo Bird and the Passenger Pigeon. Another problem is that animals lose their habitat. Mostly, animals need a minimal amount of space, where they can hunt, breed

Richard Bosman created an woodcut called the Polar Bear II in 1981, and then thirteen years later, another polar bear image was engraved by Joseph Hecht, called the Sleeping Polar Bear. In Hecht’s engraving, he created an every minimal piece, while Boseman created a very detailed piece. Although both artists used a similar subject matter, polar bears, they each created an image which related it own story by their methods, materials, and treatments of each of the pieces. Boseman evokes a nightmarish

According to Sea World, a marine and wildlife research organization, the polar bear has a layer of fat up to four and a half inches thick. This layer of fat keeps them so well insulated almost no heat escapes. Polar bears are so well insulated they tend to overheat

The objective of this experiment is to investigate if Seagulls wait around the bears while they`re finishing to eat their left over. Commensalism is a relationship between two species who live in close association and one receives a benefit (+), whereas the other is unaffected (0). My hypothesis is that the Grizzly bears and the seagulls have a commensalism relationship, where the seagulls receive benefit and the bears are unaffected. I will randomly gather photos from different time frame to look

Penguins and polar bears live in some of the coldest climates on earth. In order to survive they need to be able to insulate and keep themselves warm. For the last couple of weeks my class have been investigating how penguins and polar bears keep warm in the coldest temperatures. I am going to report how they do this and how polar bears keep warm and how this relates to penguins keeping warm. How Penguins keep warm Penguins use their feathers as insulators on land, instead of having the large

An Emperor Penguin has only one biome. The biome the Emperor Penguin is Arctic Tundra. The Emperor Penguin also lives in the water for hunting animals. The Emperor Penguins can slow down their metabolism down when necessary so they don 't get cold. They do not migrate to warmer places in the winter. The Arctic Tundra is cold and windy. The Arctic Tundra has low precipitation. It only gets less than 10 inches of rain a year. The winds are dry. Having the winds dry and the weather

Have you ever wondered why particularly in Alaska, bears need to stock up on food before winter comes? all the bears particularly in Alaska, need to stock up on food before winter comes because when winter hits food goes away. In the text it states " When the cold Alaskan winter hits, the bears’ food supply disappears. Temperatures drop, freezing the streams where tasty salmon swim. The berries that the bears snack on vanishes". This means that bears need to get food before winter hits. Getting food

The Red Snapper is also known as Lutjanus campechanus, they are pink to a red color (Louisiana Fisheries). They are commonly known as the North American Red Snapper, Snapper, Genuine Red Snapper. Their color starts to fade off under their bellies (Louisiana Fisheries). Some key characteristics are their red eyes, and their anal fin pointed than rounded. (Louisiana Fisheries). They can be found in the Gulf of Mexico and the Western Gulf (Louisiana). They can weight about anywhere ranging from 10-50

Russia and is mostly covered by ice sheets, ice floes, icebergs and sea ice. Sea Ice is a thin, fragile layer of frozen ocean water that forms in the Arctic and Antarctic oceans. On average sea ice covers 20-25 km² of the Earth, accounting for 7% of the sea surface. The maximum extent of Sea Ice in the Arctic is recorded as 13-15x 10⁶km² with the minimum coverage being 7x10⁶km². Since Satellite monitoring in 1979, there has been a decline in the extent of Sea Ice during winter months, with the lowest

According to the explanation, the author proposes that it is the melting of sea ice caused by global warming that results in the decline of the number of Arctic deer. However, unless she offers further additional evidence to strengthen her argument, the conclusion can remain, at best, unwarranted. To begin with, although some local hunters report that the deer population seems to be decreasing, it doesn’t necessarily mean that deer are really less than before. Clearly, the author assumes that the

Script Video- Background Information Video- State location of the climate type Raj- We are doing the Arctic ice cap for our climate change project. Raj- Here are some background information to help you understand more about the Arctic. The arctic is located above the Arctic Circle or north of the 65 degrees north latitude of the equator. It is in the northern polar regions, the Arctic itself is not a continent but it contain lands in North America, Europe, and Asia. Video-Average temperature

William Shakespeare, Edmund, the cold, calculating bastard of Gloucester, personifies an iceberg. According to Meriam Webster, the word iceberg has two definitions: a large floating mass of ice, detached from a glacier and carried out to sea or an emotionally cold person. While Edmund is not an actual mass of ice, he displays all the characteristics of an emotionally detached, cold person. Just as icebergs have actually killed people through terrible accidents, Edmund also has caused died to either

Contrast between two pure white continents Many people might think that the Arctic and the Antarctica share many similarities which make these two areas alike. However, though the temperatures in these two areas are both freezing under zero Celsius and the sceneries are with icy white lands, no two regions are exactly the same on this planet. To find out more interesting factors of differences between the North Pole and the South Pole, the polar bear and the penguin will lead the way. One major

fallen, the snow begins to compress. The snow changes from fluffy crystals to hard ice pellets. After new snow has fallen and covered ice pellets, the hard snow becomes more compressed, forming grainy ice called firn(the state between snow and glacier ice), as demonstrated in Figure 1. Years go by as layers of firn build up on top of each other. Once the ice has grown thick enough, the firn blends into a giant mass of ice. The process takes more than a hundred years for most glaciers (National Geographic)

The concept of climate change may be one of the greatest threats to our modern day life and the future of our planet. Climate singlehandedly is able to impact natural resources, vegetation, and human impacts on an area which and effectively destroy the functionality of an ecosystem. Many climate change deniers use the formal definition of climate to support the idea that climate change and global warming does not exist - they believe that climate is simply the natural changes in weather over time

Running water and glacial ice as shapers of the landforms and landscapes Introduction Both running water and glaciers are fundamental in shaping landscapes. Running water in streams and rivers crisscrosses the land and forms the dominant erosional process in shaping the earth’s landscape. This is because the streams and rivers form a system of moving weathered rocks from the land to the oceans and seas. They shift great large masses from one area to another and by so doing the running waters become
