Are Polar Ice Sheets Only 4500 Years Old? There certainly is an alternative explanation for the origin of the Antarctic and Greenland Ice Sheets within the creationist time frame. 5,6 To start with, the volume of the Antarctic Ice Sheet is 26.4 million km3 with an average depth of 1900 meters. The corresponding figures for the Greenland Ice Sheet are a volume of 2.9 million km3 and an average depth of 1600 meters.

The Arctic, country by country At the time, Great Britain and Russia were the big players in the Arctic and their 1825 Boundary Treaty established the boundary between what is now Alaska and the Yukon along the 141st W meridian and as far as “the Frozen Ocean.” That treaty is important to Canada’s claim in the Arctic.

Geography of the World's Oceans 5. The Arctic Ocean is the world's smallest with an area of 5,427,000 square miles (14,056,000 sq km). It extends between Europe, Asia and North America and most of its waters are north of the Arctic Circle. Its average depth is 3,953 feet (1,205 m) and its deepest point is the Fram Basin at -15,305 feet (-4,665 m). Throughout most of the year, much of the Arctic Ocean is covered by a drifting polar icepack that is an average of ten feet (three meters) thick.

Hotspot Ecosystem Research and Man's Impact On European Seas This coincides with the average depth of the bottom of the euphotic zone, which means that the deep sea is also a dark sea. The average depth of the sea is around 4,000 m (almost 2.5 miles) and the deepest point in the Mariana Trench is about 11,000 m, so there is a lot of deep sea around the world!In fact, about 90 % of the world’s ocean is deep sea.Not having any sunlight doesn’t mean that animals living in the deep sea don’t rely on it. Plant and animal matter from the euphotic zone sinks through the water column and eventually reaches the deep sea.This organic matter is known as “marine snow”, and most deep-sea animals rely on it as a food source.n fact, about 90 % of the world’s ocean is deep sea.

- The Arctic (/ˈɑrktɪk/ f) is a polar region located at the northernmost part of the Earth. The Arctic consists of the Arctic Ocean and parts of Alaska (United States), Canada, Finland, Greenland (Denmark), Iceland, Norway, Russia, and Sweden.The Arctic region consists of a vast ocean with a seasonally varying ice cover, surrounded by treeless permafrost.he Arctic's climate is characterized by cold winters and cool summers. Precipitation mostly comes in the form of snow. The Arctic's annual precipitation is low, with most of the area receiving less than 50 cm (20 in).

Iceberg Typically, about 80 to 90 percent of an iceberg is below sea level. Scientists who study icebergs classify true icebergs as pieces of ice that are higher than 16 feet (5 meters) above sea level and wider than 98 feet (30 meters) at the water line.odern iceberg research continues to focus on improving methods of tracking and monitoring icebergs, and on learning more about iceberg deterioration. In 1995, a huge iceberg broke free from the Larsen ice shelf in Antarctica. This iceberg was 48 mi (77 km) long, 23 mi (37 km) wide, and 600 ft (183 m) thick.

- As the Arctic Ocean surrounds the North Pole, the ice cover is sea ice that floats on the ocean (only about 10-20 feet / 3-6 meters thick), instead of that massive ice sheet (more than 2 miles / 3 kilometers thick in places).he ice cap over the Arctic Ocean is always moving because of the winds above it and the ocean currents beneath it. This movement causes large cracks (called leads) to open up-even in winter-and this allows ocean heat to escape into the air. Land loses heat faster than water.

How deep is the ocean? The deepest part of the ocean is called the Challenger Deep and is approximately 11,030 meters (36,200 feet) deep. It's located beneath the western Pacific Ocean in the southern end of the Mariana Trench, which runs several hundred kilometers southwest of the U.S. territorial island of Guam.

Arctic The Arctic region is a unique area among Earth's ecosystems. For example, the cultures in the region and the Arctic indigenous peoples have adapted to its cold and extreme conditions. In recent years, the extent of the sea ice has declined.he Arctic's annual precipitation is low, with most of the area receiving less than 50 cm (20 in). High winds often stir up snow, creating the illusion of continuous snowfall. Average winter temperatures can be as low as −40 °C (−40 °F), and the coldest recorded temperature is approximately −68 °C (−90 °F).

What Happens in Deep Ocean Trenches? It is approximately 1,500 miles long. The deepest portion of the Mariana Trench is the Challenger Deep, a narrow portion at the southern end, which is roughly 36,000 feet deep. The water temperature in this area is slightly above freezing. The world's ocean trenches remain largely unexplored due to the immense pressures at such depths.

The Arctic: the ocean, sea ice, icebergs, and climate Therefore the seasonal variation of the area of sea ice is smaller in the Arctic than around Antarctica. In the Arctic, the sea-ice area ranges between 9 and 12 x 106 km2 (as opposed to 4 and 19 x 106 km2 around Antarctica). As a comparison, the contiguous USA is about 9 x 106 km2 in size.

Frost line For example, snow cover and asphalt insulate the ground and homes can heat the ground (see also heat island). The line varies by latitude, it is deeper closer to the poles. It ranges in the United States from about zero to six feet. Below that depth, the temperature varies, but is always above 0 °C (32 °F).lternatively, in Arctic and Antarctic locations the freezing depth is so deep that it becomes year-round permafrost, and the term  thaw depth  is used instead. Finally, in tropical regions, frost line may refer to the vertical geographic elevation below which frost does not occur.

The Arctic Ocean is the smallest and shallowest of the five Transcript of The Arctic Ocean is the smallest and shallowest of the five. Until the 20th century it was believed that the Arctic Ocean was one large basin. The Arctic ocean is not made up of one basin, but two deep basins that are divided into four smaller oceans, by three oceanic ridges. The central ridge is called Lomonosov Ridge and is 1,770 km long.

How the Warming Arctic Affects Us All On September 16, the extent of the Arctic Ocean’s ice cap reached a new low, shrinking to 1.32 million square miles, 300,000 square miles less than the previous record low set in 2007. Some scientists believe that, at this rate, the Arctic could be ice-free by 2030 or even earlier.ccording to the Arctic Biodversity Trends 2010 report, all types of habitats—sea ice, tundra, permafrost peatlands, ponds and lakes formed by melting permafrost—are changing and impacting biodiversity.
