Frozen Planet
''Frozen Planet'' is a 2011 British nature documentary series, co-produced by the BBC and The Open University. It was filmed by the BBC Natural History Unit. The production team, which includes executive producer Alastair Fothergill and series producer Vanessa Berlowitz, were previously responsible for the award-winning series ''The Blue Planet'' (2001) and ''Planet Earth'' (2006), and ''Frozen Planet'' is billed as a sequel of sorts. David Attenborough returns as narrator. It is distributed under licence by the BBC in other countries, Discovery Channel for North America, ZDF for Germany, Antena 3 for Spain and Skai TV for Greece. The seven-part series focuses on life and the environment in both the Arctic and Antarctic. The production team were keen to film a comprehensive record of the natural history of the polar regions because climate change is affecting landforms such as glaciers, ice shelves, and the extent of sea ice. The series was met with critical acclaim and holds a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nature Documentary
A nature documentary or wildlife documentary is a genre of documentary film or series about animals, plants, or other non-human living creatures, usually concentrating on video taken in their natural habitat but also often including footage of trained and captive animals. Sometimes they are about wildlife or ecosystems in relationship to human beings. Such programmes are most frequently made for television, particularly for public broadcasting channels, but some are also made for the cinema medium. The proliferation of this genre occurred almost simultaneously alongside the production of similar television series. History In cinema Robert J. Flaherty's 1922 film ''Nanook of the North'' is typically cited as the first feature-length documentary. Decades later, Walt Disney Productions pioneered the serial theatrical release of nature-documentaries with its production of the True-Life Adventures series, a collection of fourteen full length and short subject nature films from 1948 to ...

Broadcast Syndication
Broadcast syndication is the practice of leasing the right to broadcasting television shows and radio programs to multiple television stations and radio stations, without going through a broadcast network. It is common in the United States where broadcast programming is scheduled by television networks with local independent affiliates. Syndication is less widespread in the rest of the world, as most countries have centralized networks or television stations without local affiliates. Shows can be syndicated internationally, although this is less common. Three common types of syndication are: ''first-run'' syndication, which is programming that is broadcast for the first time as a syndicated show and is made specifically to sell directly into syndication; ''off-network'' syndication (colloquially called a "rerun"), which is the licensing of a program whose first airing was on network TV or in some cases, first-run syndication;Campbell, Richard, Christopher R.

Metacritic
Metacritic is a website that review aggregator, aggregates reviews of films, TV shows, music albums, video games and formerly, books. For each product, the scores from each review are averaged (a weighted arithmetic mean, weighted average). Metacritic was created by Jason Dietz, Marc Doyle, and Julie Doyle Roberts in 1999. The site provides an excerpt from each review and hyperlinks to its source. A color of green, yellow or red summarizes the critics' recommendations. It is regarded as the foremost online review aggregation site for the video game industry. Metacritic's scoring converts each review into a percentage, either mathematically from the mark given, or what the site decides subjectively from a qualitative review. Before being averaged, the scores are weighted according to a critic's popularity, stature, and volume of reviews. The website won two Webby Awards for excellence as an aggregation website. Criticism of the site has focused on the assessment system, the ass ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Ice
Sea ice arises as seawater freezes. Because ice is less dense than water, it floats on the ocean's surface (as does fresh water ice, which has an even lower density). Sea ice covers about 7% of the Earth's surface and about 12% of the world's oceans. Much of the world's sea ice is enclosed within the polar ice packs in the Earth's polar regions: the Arctic ice pack of the Arctic Ocean and the Antarctic ice pack of the Southern Ocean. Polar packs undergo a significant yearly cycling in surface extent, a natural process upon which depends the Arctic ecology, including the ocean's ecosystems. Due to the action of winds, currents and temperature fluctuations, sea ice is very dynamic, leading to a wide variety of ice types and features. Sea ice may be contrasted with icebergs, which are chunks of ice shelves or glaciers that calve into the ocean. Depending on location, sea ice expanses may also incorporate icebergs. General features and dynamics Sea ice does not simply grow and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ice Shelf
An ice shelf is a large floating platform of ice that forms where a glacier or ice sheet flows down to a coastline and onto the ocean surface. Ice shelves are only found in Antarctica, Greenland, Northern Canada, and the Russian Arctic. The boundary between the floating ice shelf and the anchor ice (resting on bedrock) that feeds it is the grounding line. The thickness of ice shelves can range from about to . In contrast, sea ice is formed on water, is much thinner (typically less than ), and forms throughout the Arctic Ocean. It is also found in the Southern Ocean around the continent of Antarctica. The movement of ice shelves is principally driven by gravity-induced pressure from the grounded ice. That flow continually moves ice from the grounding line to the seaward front of the shelf. In steady state, about half of Antarctica's ice shelf mass is lost to basal melt and half is lost to calving, but the relative importance of each process varies significantly between ice s ...

Glacier
A glacier (; ) is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its Ablation#Glaciology, ablation over many years, often Century, centuries. It acquires distinguishing features, such as Crevasse, crevasses and Serac, seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand.

Climate Change
In common usage, climate change describes global warming—the ongoing increase in global average temperature—and its effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global average temperature is more rapid than previous changes, and is primarily caused by humans burning fossil fuels. Fossil fuel use, deforestation, and some agricultural and industrial practices increase greenhouse gases, notably carbon dioxide and methane. Greenhouse gases absorb some of the heat that the Earth radiates after it warms from sunlight. Larger amounts of these gases trap more heat in Earth's lower atmosphere, causing global warming. Due to climate change, deserts are expanding, while heat waves and wildfires are becoming more common. Increased warming in the Arctic has contributed to melting permafrost, glacial retreat and sea ice loss. Higher temperatures are also causing m ...

Antarctic
The Antarctic ( or , American English also or ; commonly ) is a polar region around Earth's South Pole, opposite the Arctic region around the North Pole. The Antarctic comprises the continent of Antarctica, the Kerguelen Plateau and other island territories located on the Antarctic Plate or south of the Antarctic Convergence. The Antarctic region includes the ice shelves, waters, and all the island territories in the Southern Ocean situated south of the Antarctic Convergence, a zone approximately wide varying in latitude seasonally. The region covers some 20 percent of the Southern Hemisphere, of which 5.5 percent (14 million km2) is the surface area of the Antarctica continent itself. All of the land and ice shelves south of 60°S latitude are administered under the Antarctic Treaty System. Biogeographically, the Antarctic realm is one of eight biogeographic realms of Earth's land surface. Geography As defined by the Antarctic Treaty System, the Antarctic r ...

Arctic
The Arctic ( or ) is a polar regions of Earth, polar region located at the northernmost part of Earth. The Arctic consists of the Arctic Ocean, adjacent seas, and parts of Canada (Yukon, Northwest Territories, Nunavut), Danish Realm (Greenland), Finland, Iceland, Norway, Russia (Murmansk Oblast, Murmansk, Siberia, Nenets Autonomous Okrug, Nenets Okrug, Novaya Zemlya), Sweden and the United States (Alaska). Land within the Arctic region has seasonally varying snow and sea ice, ice cover, with predominantly treeless permafrost (permanently frozen underground ice) containing tundra. Arctic seas contain seasonal sea ice in many places. The Arctic region is a unique area among Earth's ecosystems. The cultures in the region and the Arctic indigenous peoples have adapted to its cold and extreme conditions. Life in the Arctic includes zooplankton and phytoplankton, fish and marine mammals, birds, land animals, plants and human societies. Arctic land is bordered by the subarctic. De ...

Skai TV
Skai TV (Greek: ΣΚΑΪ) is a Greek free-to-air television network based in Piraeus. It is part of the Skai Group, one of the largest media groups in the country. It was relaunched in its present form on 1 April 2006 in the Athens metropolitan area, and gradually spread its coverage nationwide. Besides digital terrestrial transmission, it is available on the subscription-based encrypted services of Nova and Cosmote TV. Skai TV is also a member of Digea, a consortium of private television networks introducing digital terrestrial transmission in Greece. At launch, Skai TV opted for dubbing all foreign language content into Greek, instead of using subtitles. This is very uncommon in Greece for anything except documentaries (using voiceover dubbing) and children's programs (using lip-synced dubbing), so after intense criticism, the station switched to using subtitles for almost all foreign shows. History Skai TV was first launched on 21 September 1993 with an emphasis on news an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
