FLYING OVER ARCTIC SEA ICE | Stunning Aerial Footage
FLYING OVER ARCTIC SEA ICE | Stunning NASA Footage - From the Cockpit: The Best of IceBridge Arctic 2013 - The views from the cockpit of NASA's P-3B aircraft on an Operation IceBridge campaign are truly stunning. The mission doesn't travel to both ends of the Earth for the scenery of course -- the airborne mission is there to collect radar, laser altimetry, and other data on the changing ice sheets, glaciers, and sea ice of the Arctic and Antarctic. But for those of us who aren't polar pilots, here's a selection of some of the best footage from the forward and nadir cameras mounted to the aircraft taken during IceBridge's spring deployment over Greenland and the Arctic Ocean. - SUBSCRIBE to Bright Enlightenment http://www.youtube.com/BrightEnlightenment - On FACEBOOK: http://www.Facebook.com/BrightEnlightenment - Visit our WEBSITE: http://www.BrightEnlightenment.com -TWITTER: https://twitter.com/BrightEnlight - GOOGLE+ https://plus.google.com/u/1/105692605238227581556/ Credit: NASA's Goddard Space Flight Center #NASA #documentary #flying #Greenland #SeaIce #ClimateChange #GlobalWarming #film #BrightEnlightenment

Antarctica (Between ice floes) Part 4
Welcome to my travelchannel.On my channel you can find almost 1000 films of more than 70 countries. See the playlist on my youtube channel.Enjoy! https://www.youtube.com/user/nurettinodunya/playlists Antarctica Climate: Antarctica is the coldest of Earth's continents. The coldest natural temperature ever recorded on Earth was −89.2 °C (−128.6 °F) at the Russian Vostok Station in Antarctica on 21 July 1983. For comparison, this is 11 °C (20 °F) colder than subliming dry ice. Antarctica is a frozen desert with little precipitation; the South Pole itself receives less than 10 cm (4 in) per year, on average. Temperatures reach a minimum of between −80 °C (−112 °F) and −90 °C (−130 °F) in the interior in winter and reach a maximum of between 5 °C (41 °F) and 15 °C (59 °F) near the coast in summer. Sunburn is often a health issue as the snow surface reflects almost all of the ultraviolet light falling on it. The snow surface at Dome C Station is typical of most of the continent's surface. East Antarctica is colder than its western counterpart because of its higher elevation. Weather fronts rarely penetrate far into the continent, leaving the center cold and dry. Despite the lack of precipitation over the central portion of the continent, ice there lasts for extended time periods. Heavy snowfalls are not uncommon on the coastal portion of the continent, where snowfalls of up to 1.22 metres (48 in) in 48 hours have been recorded.At the edge of the continent, strong katabatic winds off the polar plateau often blow at storm force. In the interior, however, wind speeds are typically moderate. During summer, more solar radiation reaches the surface during clear days at the South Pole than at the equator because of the 24 hours of sunlight each day at the Pole. Antarctica is colder than the Arctic for three reasons. First, much of the continent is more than 3 kilometres (2 mi) above sea level, and temperature decreases with elevation in the troposphere. Second, the Arctic Ocean covers the north polar zone: the ocean's relative warmth is transferred through the icepack and prevents temperatures in the Arctic regions from reaching the extremes typical of the land surface of Antarctica. Given the latitude, long periods of constant darkness or constant sunlight create climates unfamiliar to human beings in much of the rest of the world. Third, the Earth is at aphelion in July (i.e., the Earth is furthest from the Sun in the Antarctic winter), and the Earth is at perihelion in January (i.e., the Earth is closest to the Sun in the Antarctic summer). The orbital distance contributes to a colder Antarctic winter (and a warmer Antarctic summer) but the first two effects have more impact. The aurora australis, commonly known as the southern lights, is a glow observed in the night sky near the South Pole created by the plasma-full solar winds that pass by the Earth. Another unique spectacle is diamond dust, a ground-level cloud composed of tiny ice crystals. It generally forms under otherwise clear or nearly clear skies, so people sometimes also refer to it as clear-sky precipitation. A sun dog, a frequent atmospheric optical phenomenon, is a bright "spot" beside the true sun.Wikipedia

SAMCoT 2013 cruise to the Fram Strait
The Oden Arctic Research Technology Cruise 2013 took ice researchers and marine mammal biologists to the icy waters off the northeast coast of Greenland, in an area called the Fram Strait in late August and early September. Researchers tested new ice detection and measurement technologies, measured ice thicknesses and strength, tested different ice management and manoeuvring techniques, tracked icebergs, and looked for (and found) marine mammals, including several sightings of the very rare bowhead whale. Researchers also used hydrophones to listen to marine mammal sounds and the sounds of the icebreaker under the ice.

NOAA Ocean Today video: 'Arctic Exploration'
The Arctic is one of the most remote and uncharted areas of the world. With so many amazing things just waiting to be discovered, Arctic exploration is truly a new scientific frontier. http://oceantoday.noaa.gov/arcticexploration/welcome.html and http://www.arctic.noaa.gov/reportcard/ ------------------------------------------ TRANSCRIPT: The Arctic region includes a vast, ice-covered ocean. This pristine yet rugged environment is one of the least explored and understood places on Earth. Due to climate changes, summer Arctic ice cover is diminishing, and scientists therefore believe it is vitally important to get a better understanding of this environment and what impact future changes might bring to our world. Operating from the U.S. Coast Guard icebreaker Healy, NOAA scientists have been involved in studying the sea ice, the water column, and the sea floor. Their missions have used the latest cutting-edge technology. One recent expedition sent a remotely operated vehicle, equipped with a high definition camera, as deep as 9000 feet, providing us with a never-before-seen view into the frigid waters. By using the ROV, multi-nets, and bottom trawlers, scientists were also able to collect samples of creatures in the water column and on the sea floor, some of which were previously unknown. A technique called ice coring was also utilized to help gather information on sea ice algae. All of this research has helped create a more complete understanding of the Arctic food web, and the linkages that exist between the ice, water, and sea floor in this harsh environment. Scientists aboard the Healy have also been mapping the Arctic sea floor. A multibeam echo sounder has been used to create three-dimensional views of the bottom of the ocean. These maps can help scientists understand the geological aspects and the climate history of the Arctic. This technology also led to the discovery of a new and complex underwater mountain. The Healy seamount is a stunning find that rises more than 3,000 meters off the ocean floor. The Arctic is one of the most remote and uncharted areas of the world. With all the amazing discoveries hidden in the ice and water, Arctic exploration can truly be considered a new scientific frontier.

Climate Change Shifting North Pole
Climate change is shifting Earth's poles. According to a study in Geophysical Research Letters, the Earth's geographic poles are shifting as a result of global warming. The University of Texas at Austin researchers identified the melting of Greenland's ice sheet as the primary cause of the North Pole's centimeters-per-year increased movement since 2005. Prior to that year, starting in 1982, the pole drifted southeast towards Labrador, Canada at a rate of 2 milliarcseconds -- about 6 centimeters - per year. Since 2005 it's changed speed and direction, moving at 7 milliarcseconds per year on an eastbound path towards Greenland. The movement that caught the attention of the lead author wasn't the typical season-driven polar drift, it was a change in the underlying year-long continental drift pattern. He and his colleagues, with the help of some of NASA's extensive data, concluded that the change was overwhelmingly attributable to ice loss and the rising sea levels it brings. The melting of ice in the Arctic has increased at such a rapid rate that some experts believe there could be iceless seasons in the area in as little as 10 to 30 years.

Northern Hemisphere Ice Coverage Over Last 400,000 Years
In this animation by Japanese climate scientist Ayako Abe-Ouchi, the northern ice sheets gradually grow, reaching their peak at about 20,000 years ago. Ice grows in periods with relatively low levels of carbon dioxide and sunlight falling on Earth's surface, driven by its orbit and orientation towards the sun. But in a new study in Nature, Abe-Ouchi, Lamont-Doherty scientist Maureen Raymo and others, show that the size of the ice sheet and the topography of the land below also play important roles in determining whether the ice gets bigger or smaller.

Giant Singapore-Sized Iceberg Breaks Off From Antarctica
An iceberg around the same size as Singapore has broken off the Pine Island Glacier in Antarctica, and is floating out into the ocean. An iceberg around the same size as Singapore has broken off the Pine Island Glacier in Antarctica, and is floating out into the ocean. Researchers have been observing the iceberg using satellite surveillance while waiting for it to move out to sea after it separated from the glacier around six months ago. It took more than two years for the iceberg to calve since the NASA IceBridge research team first noticed an enormous crack in the surface back in October of 2011. Grant Bigg, an ocean modeler at the University of Sheffield in the United Kingdom said: "Each of the last three years has seen a giant iceberg calve, from either Greenland or Antarctica. Being able to track and forecast the tracks of these huge blocks of ice will be a major benefit to the shipping industry, particularly as more ships begin to use polar waters, as Arctic sea ice melts." Bigg and his team of scientists will be predicting the movement of the giant iceberg using what they know about ocean currents and prevailing winds to ensure that international shipping routes are safe from the floating frozen obstacle.

Ross Ice Shelf
Seasonal Sea Ice Breakup Near the Ross Ice Shelf: Image of the Day. Courtesy Video | NASA | Date: 06.26.2011. This true-color scene is situated along Antarctica's Scott Coastline (toward the west, or lefthand side, of the image), looking out toward the Ross Sea (eastward, or toward the right). Near the top of the image, the Drygalski Ice Tongue juts eastward roughly 80 km (50 miles) out from the coast. Just below this ice tongue is a cluster of large icebergs surrounded by a large bed of sea ice. The large, coke bottle-shaped iceberg toward the lower right was named B-15 by scientists; it captured the attention of the news media last year when it broke off from the Ross Ice Shelf and began drifting out to sea. Its progress was impeded by Ross Island (bottom center), which eventually contributed to breaking B-15 almost in half. The remaining portion of B-15, which is about the size of Delaware (roughly 160 km long), remains trapped by Ross Island. A large phytoplankton bloom (greenish swirls in the dark water) can be seen in the ocean toward the top of the scene. This image was acquired by the Moderate-resolution Imaging Spectroradiometer (MODIS), flying aboard NASA's terra.nasa.gov/ Terra satellite, on January 4, 2002. Click to view a time-series animation of the scene. Each frame of the movie is a snapshot taken by MODIS almost every day from December 17, 2001, through January 4, 2002. As the movie plays, notice how a number of large icebergs calve off from the shoreline ice shelf and begin slowly moving eastward. Perhaps this is due to the arrival of summer in the Southern Hemisphere, which brings warmer air and water temperatures to the region. The relatively thinner sea ice is pushed around much more easily by shifting wind and water currents than the thicker, heavier icebergs. Yet, they are all hemmed in by the massive B-15 iceberg, which ultimately blocks them from escaping out to sea. In the last frame of the movie, it appears that a strong wind has pushed the entire ice mass back toward the Scott Coast, where it may re-freeze and become connected again to the Drygalski Ice Tongue.

ESA - CryoSat-2 - Volume dei ghiacci in Artico dal 2003 al 2012
An international team of scientists using new measurements from ESA's ice mission has discovered that the volume of Arctic sea ice has declined by 36% during autumn and 9% during winter between 2003 and 2012. Satellite records show a constant downward trend in the area covered by Arctic sea ice during all seasons, but in particular in summer. The past six years have seen the lowest summer ice extent in three decades, reaching the lowest last September at about 3.61 million sq km. A team of scientists led by University College London has now generated estimates of the sea-ice volume for the 2010--11 and 2011--12 winters over the Arctic basin using data from ESA's CryoSat satellite. This study has confirmed, for the first time, that the decline in sea ice coverage in the polar region has been accompanied by a substantial decline in ice volume. The new CryoSat dataset shows the volume's continuing decline observed from 2003 to 2008 by NASA's ICESat satellite. Sea ice thickness Since 2008, the Arctic has lost about 4300 cubic km of ice during the autumn period and about 1500 cubic km in winter. The team confirmed CryoSat estimates using independent ground and airborne measurements carried out by ESA and international scientists during the last two years in the polar region, as well as by comparing measurements from NASA's Operation IceBridge. "The data reveal that thick sea ice has disappeared from a region to the north of Greenland, the Canadian Archipelago and to the northeast of Svalbard," said Katharine Giles, co-author of the study 'CryoSat-2 estimates of Arctic sea ice thickness and volume', recently published online in Geophysical Research Letters. "Other satellites have already shown drops in the area covered by Arctic sea ice as the climate has warmed, but CryoSat allows scientists to estimate the volume of sea ice -- a much more accurate indicator of the changes taking place in the Arctic," added Tommaso Parrinello, CryoSat Mission Manager. To do this, CryoSat's high-resolution radar altimeter sends pulses of microwave energy down towards the ice. The energy bounces off both the top sections of ice and the water in the cracks between. The difference in height between these two surfaces allows scientists to calculate the 'freeboard' -- the height of ice above the water -- and, as a result, volume of the ice cover. While the researchers say two years of CryoSat data aren't indicative of a long-term change, they speculate that the lower ice thickness and volume in the winter of 2012, compared to the winter of 2011, may have contributed to the record minimum ice extent during the 2012 autumn.

Helsinki Shipyard won contract for icebreaking supply vessel to serve Sakhalin 1, Orlan field in 2003. The requirements for the vessel operations and performance in harsh surroundings like drifting icefields or ice-ridges frozen to bottom (till 15...20m) were extremely tough. The design of Helsinki Shipyard was very successful in utilising the DAS-concept to overcome these challenges and SCF Sakhalin become one of the most sophisticated and versatile ships ever built for arctic operations.
Scientists find tower-high channel beneath Antarctica ice shelf
Sign up for a free trial of News Direct's animated news graphics at http://newsdirect.nma.com.tw/Reuters.aspx UK scientists have found huge ice channels under the Filchner-Ronne Ice Shelf in West Antarctica. Giant channels of water said to be almost as tall as the Eiffel Tower are flowing beneath the ice shelf. The study was conducted by researchers at the University of Exeter and colleagues from Newcastle University and the University of Bristol. They used satellite images and airborne radar measurements to find meltwater channels. It was reported that one of the newly discovered ice-channels was about 250 meters high and 300 meters wide, similar in height to the Eiffel Tower and Tower Bridge of London in width. The study shows that once the cold melt water from the ice shelf reaches the sea, it forms a plume and warms the surrounding sea water. The warmed water then wears a channel into the floating ice of the Filchner-Ronne Ice Shelf. Previously, it was believed that melt water which builds up on land would flow into the sea in a thin layer, rather than in concentrated channels. It was reported that the scientists believe ice channels play an important role in stabilizing the ice shelf. This discovery can help researchers understand how Antarctica will respond to climate change in the future.

Gibraltar Breach.mov
Six million years ago, the Mediterranean Sea nearly dried up during what is called the "Messinian Salinity Crisis". This movie shows a physics-based computer simulation of the breach of Gibraltar and the flood of the basin. A similar event 10,000 years ago, in the then populated Black Sea basin, may have been the source of the Noah's Arc narrative.

As sea ice melts, storm surges batter Arctic coasts
As each Arctic summer brings less sea ice, two new studies warn of major changes, from devastating storm surges to huge increases in shipping. Rising temperatures in the Arctic — a result of global climate change — are bringing bigger and stronger storms, with hurricane-equivalent winds, previous research shows. And the region's dwindling sea ice cover (Sept. 2012 saw a record summer sea ice low, NASA reported) means storms can charge across the ocean without restraint. Thick summer sea ice once slowed down Arctic storm winds, stopping them from generating high storm surges, the bulge of water that builds up ahead of a storm that can batter and flood a coastline. One of the new studies tracked 400 years of storm surges in Canada's Mackenzie River delta, and found the wave-borne floods are becoming stronger and more frequent. "I think it's another piece of the puzzle that suggests the Arctic is changing very rapidly and these changes are related to what's going on with respect to climate change," said study co-author Michael Pisaric, a biogeographer at Brock's University in Ontario, Canada. "Storms are growing larger and stronger, and there's so much more open water for these storms to blow across. These two [factors] combined are creating new conditions for the Arctic that when you put increasing infrastructure and exploration for hydrocarbons, that's starting to create a recipe for disaster," Pisaric told OurAmazingPlanet. Hydrocarbon exploration in the Arctic includes floating and fixed oil and gas wells. [8 Ways Global Warming Is Already Changing the World The findings were detailed online Jan. 25 in the journal Geophysical Research Letters. Flooding low-lying coasts The Mackenzie River delta and its inhabitants are still struggling to recover from the shocking effects of a massive storm surge in 1999. Pisaric and his colleagues collaborated with Inuvialuit of the northwest Arctic to document changes since the 1999 storm surge. "They alerted us to the fact that everything was dead out there," Pisaric said. Saltwater killed 37 percent of the region's plant life within five years, and the soil remains contaminated with high salt concentrations, a 2011 study found. Because no plants are growing to provide food, wildlife has moved away. "The hunters and trappers were very clear they don't go to this region anymore," Pisaric said. Sediment in the many lakes dotting the low-lying river delta record the history of storm surge floods, Pisaric said. In the past 400 years, the 1999 event was the biggest storm surge in the sediment layers. "The story we're seeing is not just this region, but potentially other parts of the Arctic that are very low-lying could be susceptible to these types of storm surges," Pisaric said.

7 Continents of the World - Geography for Kids | Educational Videos by Mocomi
7 Continents of the world and more geography facts. Continents are very large landmasses found on Earth. The Earth has seven such continents. They are (from largest in size to the smallest): Asia, Africa, North America, South America, Antarctica, Europe and Australia. Asia - Asia is the world’s largest and most populous continent on Earth. It covers 30% of the Earth’s land area. Asia hosts about 60% of the world’s current human population. Africa - Africa is the second-largest and also the second most populated continent in the world, after Asia. The continent of Africa covers 20.4% of the world’s total land area. Africa has a population of 1 billion which accounts for about 14.72% of the world’s human population. North America - North America is the third largest continent. It occupies 16.5% of the planet’s land area. In 2008, its population was estimated at nearly 529 million people. It is the fourth most populous continent after Asia, Africa and Europe. South America - South America is the fourth largest continent in terms of area. It is also the fifth most populous continent after Asia, Africa, Europe and North America. South America is bordered on the west by the Pacific Ocean and to the north and east by the Atlantic Ocean. Antarctica - Antarctica is the fifth largest continent in area. About 98% of Antarctica is covered by ice that averages about 1.6 kilometers in thickness. It is the coldest, driest and windiest continent. Antarctica is considered a desert, with only 8 inches of rainfall in a year. There are no permanent residents on this island, but only a few thousands of people, who live here at the research stations found across the continent. Europe - Europe by convention, is one of the world’s seven continents divided from Asia by the Ural mountains stretching right up to the Caspian Sea. It is the world’s second-smallest continent by surface area. It covers about 6.8% of the Earth’s surface area. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south, and the Black Sea to the south east. Australia - Australia is the smallest and lowest-lying human-inhabited continent on Earth. As Australia is mostly on a single landmass, it is also referred to as an “island” continent, surrounded by oceans. The continent of Australia also includes nearby islands Tasmania, New Guinea, the Aru Islands, and the Raja Ampat Islands, geologically.

Glacier in Antarctica Breaks into Large Iceberg
The Pine Island Glacier on the west side of Antarctica is the fastest flowing, longest glacier on Earth, and it has just cracked to produce a giant iceberg. The Pine Island Glacier on the west side of Antarctica is the fastest flowing, longest glacier in Antarctica, and it has just broken to produce a giant iceberg. The iceberg that broke off is around 277 square miles, more than half the size of New York City. Using a satellite, researchers have been keeping an eye on the Pine Island Glacier, ever since NASA captured the first pictures of it cracking in October of 2011. The glacier melt might be caused by warmer ocean water getting underneath the ice shelf. Icebergs break off from the glacier naturally every 6 to 10 years, and significantly large icebergs also reportedly broke off in 2001 and 2007. Professor David Vaughan from the British Antarctic Survey said that it "is the most rapidly shrinking glacier on the planet. It's losing more ice than any other glacier on the planet, and it's contributing to sea level rise faster than any other glacier on the planet. That makes it worthy of study." Now researchers are watching the Pine Island Glacier's iceberg to see how long it takes to melt, and how it will affect the Southern Antarctic Ocean.
