Older Arctic Sea Ice Disappearing
 
02:36
Arctic sea ice has not only been shrinking in surface area in recent years, it’s becoming younger and thinner as well. In this animation, where the ice cover almost looks gelatinous as it pulses through the seasons, cryospheric scientist Dr. Walt Meier of NASA Goddard Space Flight Center describes how the sea ice has undergone fundamental changes during the era of satellite measurements. Editor’s note: This visualization incorrectly identifies the oldest ice as being 5+ years old, when it would be more accurate to say 4+ years old.

Methane in Arctic - Sunday 13 Jan to Tuesday 15 Jan, 2019
 
04:10
There are huge amounts of methane in the region of Novaya Zemlya in Siberia. Sea surface temperature on Nulschool readings of minus 1/5 C lend credence to the idea that the methane is coming up from below. The freezing temperature of salt water is minus 21C. That has implications for the integrity of the ice.

But rather than sit by and watch as the sea ice disappears from the region at an unprecedented rate, scientists have hatched a crazy plan to 'refreeze' the Arctic, by installing some 10 million wind-powered pumps over the ice cap to spray sea water over the surface and replenish the sea ice." Arctic ice management http://onlinelibrary.wiley.com/doi/10.1002/2016EF000410/full "As the Earth's climate has changed, Arctic sea ice extent has decreased drastically. It is likely that the late-summer Arctic will be ice-free as soon as the 2030s. This loss of sea ice represents one of the most severe positive feedbacks in the climate system, as sunlight that would otherwise be reflected by sea ice is absorbed by open ocean. It is unlikely that CO2 levels and mean temperatures can be decreased in time to prevent this loss, so restoring sea ice artificially is an imperative."

One proposal to try to halt this warming is literally out-of-this-world: a giant, space-based sunshade. We're already modifying our climate by accident, so why not do it by deliberate geoengineering? It's a radical idea, and it just might just work. Reducing the amount of light reaching our planet could cool the Earth quickly, even with rising carbon dioxide levels." ____________________ DNews is dedicated to satisfying your curiosity and to bringing you mind-bending stories & perspectives you won't find anywhere else!

Arctic sea ice regrowth is unprecedentedly eff'd: Part 1/2
 
15:01
Arctic sea ice regrowth is eff'd this year; in fact is truly horrible. As the ice extent, defined as regions with at least 15% ice tries to expand via sea water freezing; it is melted out by extremely high sea surface temperatures. Then the cooled surface water mixes via wave action with warmer water down to as much as 200 meters and the warm mixtures at the surface continue the process of sea ice melting. Without strong ice regrowth, we will reach the state we are heading to. Namely, zero sea ice. We must break this vicious cycle, by declaring a global climate emergency, and implementing the three-legged-stool solution set.

The Arctic Ocean Monthly Temperature climatolgy
 
00:49
The Arctic Ocean monthly temperature climatology is animated at the surface, 100m, 500m and 1000m. Images are downloaded from NOAA/NODC/OCL (http://www.nodc.noaa.gov/OC5/regional_climate/arctic/). The Arctic Ocean is an area of intense activity both for environmental and commercial interests. Climate change has disproportionally affected this region with rising ocean temperatures and continued loss of summer sea ice extent. Oil and mineral exploration and exploitation are occurring and intensifying. To facilitate study of the region, NOAA-NODC Regional Climatology Team1 developed a new set of high-resolution long-term mean surface/subsurface temperature and salinity fields. These mean fields incorporate a great deal of data not previously available.

2015 Arctic sea ice minimum
 
00:22
The Japan Aerospace Exploration Agency (JAXA) provides many water-related products derived from data acquired by the Advanced Microwave Scanning Radiometer 2 (AMSR2) instrument aboard the Global Change Observation Mission 1st-Water "SHIZUKU" (GCOM-W1) satellite. Two JAXA datasets used in this animation are the 10-km daily sea ice concentration and the 10 km daily 89 GHz Brightness Temperature. In this animation, the daily Arctic sea ice and seasonal land cover change progress through time, from February 25, 2015 through the 11th of September, 2015, when the ice reaches its annual minimum extent. Over the water, Arctic sea ice changes from day to day showing a running 3-day minimum sea ice concentration in the region where the concentration is greater than 15%. The blueish white colour of the sea ice is derived from a 3-day running minimum of the AMSR2 89 GHz brightness temperature. Over the land, monthly data from the seasonal Blue Marble Next Generation fades slowly from month to month. Download the visualization: https://svs.gsfc.nasa.gov/cgi-bin/details.cgi?aid=4355.

Arctic Sea Ice from January 1, 2013 to September 10, 2016
 
03:03
This visualization shows the daily Arctic sea ice and seasonal land cover change progress through time, from January 1, 2016, through September 10, 2016 when the sea ice reached its annual minimum extent for the year. The 2016 Arctic sea ice minimum is the second lowest minimum extent on the satellite record, 4.14 million square kilometers (1.60 million square miles). Here the sea ice changes from day to day showing a running 3-day minimum sea ice concentration in the region where the concentration is greater than 15%. The blueish white color of the sea ice is derived from a 3-day running minimum of the AMSR2 89 GHz brightness temperature. Over the terrain, monthly data from the seasonal Blue Marble Next Generation fades slowly from month to month. Satellite-based passive microwave images of the sea ice have provided a reliable tool for continuously monitoring changes in the Arctic ice since 1979. Every summer the Arctic ice cap melts down to what scientists call its "minimum" before colder weather begins to cause ice cover to increase. The first six months of 2016 have been the warmest first half of any year in our recorded history of surface temperature (which go back to 1880). Data shows that the Arctic temperature increases are much bigger, relatively, than the rest of the globe.

18 Amazing Facts about Arctic Ocean
 
03:31
Approximately 25% of the undiscovered petroleum is believed to be located in the Arctic Ocean. The Titanic sank because it ran into an iceberg that had broken away from a glacier from the Arctic Ocean. More fish species are found in the Arctic Ocean than anywhere else in the world. The Arctic Ocean is the smallest and shallowest of the world's five major oceans. The International Hydrographic Organization (IHO) recognizes it as an ocean, although some oceanographers call it the Arctic Mediterranean Sea or simply the Arctic Sea, classifying it a mediterranean sea or an estuary of the Atlantic Ocean. It is also seen as the northernmost part of the all-encompassing World Ocean. Located mostly in the Arctic north polar region in the middle of the Northern Hemisphere, the Arctic Ocean is almost completely surrounded by Eurasia and North America. It is partly covered by sea ice throughout the year and almost completely in winter. The Arctic Ocean's surface temperature and salinity vary seasonally as the ice cover melts and freezes; its salinity is the lowest on average of the five major oceans, due to low evaporation, heavy fresh water inflow from rivers and streams, and limited connection and outflow to surrounding oceanic waters with higher salinities. The summer shrinking of the ice has been quoted at 50%. The US National Snow and Ice Data Center (NSIDC) uses satellite data to provide a daily record of Arctic sea ice cover and the rate of melting compared to an average period and specific past years Follow us on Facebook : https://web.facebook.com/timelineyoutube/ For Suggestions comment

I discuss a recently published paper (May, 2016) titled "Effects of climate change on methane emissions from seafloor sediments: A review". Rapidly declining sea ice and snow cover is darkening the Arctic, leading to large temperature amplification. I talk about some of the paper highlights, and how a warmer, wavier and more open Arctic is leading to many physical and geochemical processed that are causing increased methane concentrations in both the water column and the atmosphere.

Arctic Spring Seasonal Temperature Trend [HD]
 
00:26
The Arctic region has been an area of scientific interest because it is expected that global warming signals will be amplified in the region because of ice-albedo feedback effect. Such effect is associated with the high albedo of snow and sea ice covered areas compared to that of ice free ocean and land areas. This animation depicts the 28-year spring seasonal surface temperature trend over the Arctic region determined from data collected during the months of March, April and May between 1982 and 2009. In this animation, the warming and cooling regions are revealed in steps of .02 degrees change per year starting with the regions of greatest change and progressing to the areas of least change. Blue hues indicate cooling regions while red hues depict warming. The neutral region of -.01 to +.01 degrees is shown in white. Brighter regions indicate greater temperature change while light regions indicate less. On the left side, the colarbar shows cooling temperatures ranging from -0.42 to zero degrees Kelvin, while the colorbar on the right shows warming temperatures ranging from zero to +0.42 degrees per year. An animated bar beside each colorbar brackets the range of data values being displayed.

Properties and circulation on a North Atlantic and Arctic Oceans' dense isopycnal layer
 
01:16
The animations show water temperature, velocity magnitude and salinity (4 months each) on the potential density surface σ3= 41.34 kg*m-3 during year 2007 from a MITgcm 4-km resolution ocean simulation. The density surface abruptly changes depth east and west of Greenland, being shallower (at around 200m) in the Arctic Ocean, Baffin Bay and Nordic Seas, where the upper ocean is colder and therefore denser, and deeper (at about 2000m) in the North Atlantic, where warm and light water occupies the upper ocean. The dense water surface “cascades” down the continental slope south of the Denmark Strait and Iceland-Scotland overflow regions, which are the routes of dense water export from the Nordic Seas. The temperatures at the shown density are generally much warmer and the salinities much higher in the North Atlantic than in the Arctic Ocean and Nordic Seas, with the exception of the region off Norway, where the warm and salty Atlantic inflow progresses northwards towards the Barents Sea and Fram Strait. The strongest currents can be seen where the dense water is flowing out of the Nordic Seas “cascading” down the continental slope south of the Denmark Strait and of the Iceland-Scotland Ridge. Besides those overflow regions, water has large speeds generally all along western boundaries and within ocean eddies.
Arctic Sea Ice; A View to a KILL: A

There is basically NO thick ice left on the Arctic Ocean surface. The thicker ice was mostly exported out to destruction via the Fram Strait & Canadian Archipelago last winter. Ice left is only a weak semblance of its former self, fractured and broken into small pieces & subject to whims of surface currents & winds. I discuss relentless ice melt on the surface from warm air temperatures & rain, below from warm ocean water, & on the edges from waves, winds & export. Not a pretty picture.

El Niño: Sea Surface Temperature and Sea Surface Height Anomalies
 
00:39
The animation illustrates the evolution of sea surface temperature (SST) and sea surface height (SSSH) anomalies* (relative to the respective normal state, i.e., seasonal climatology) associated with the 2009-10 El Nino in the Pacific Ocean. SST and SSH anomalies reflect the heat content in the mixed layer (approximately upper 50 m) and the upper ocean (approximately upper 150 m) respectively. They provide complimentary views of the oceanic signature of climate variability El Nino. In April 2009, initial warming appeared in the eastern equatorial Pacific and grew into a moderate warming event by the end of the year. The event decays somewhat during the first two months of 2010, but later strengthens so that it now ranks in the top ten of the strongest events observed to date. The latest data shows the surface warming extending farther westward across the dateline than was seen in most of the El Nino events in the past few decades. *Data: The SST data are obtained from a blended AMSR-E and MODIS product. The seasonal climatology of SST (derived from AVHRR Pathfinder SST for the period of 1982-2008) is subtracted from the AMSR-E and MODIS blended data to produce the anomaly. The SSH data are from the OSTM/JASON-2 satellite altimetry mission. The seasonal climatology of the SSH data is for the period of 1993-2008.

Zero Arctic Sea Ice Very Likely By 2020
 
14:59
There is a very high probability that the Arctic sea ice will essentially vanish by the end of summer melt in 2020 or earlier. The ice-free duration would likely be less than one-month in September for this first "blue-ocean" event. I discuss the stories in the observations leading me to this conclusion. If the ice goes, it will affect every human, plant and animal living on our planet. Please support my videos with a donation at http://paulbeckwith.net

A New Forecast Model Gives Scientists a Longer View of Arctic Sea Ice
 
01:29
Arctic sea ice extent ebbs and flows with the seasons. During the summer months, the ice melts and the edge recedes northward, usually reaching its annual minimum sometime in September. The ice extent is shaped by a variety of factors, including warmer temperatures, storms, and changes in the ocean, which makes it difficult to predict. Sea ice plays an important role in maintaining Earths temperature, so predicting how the ice extent might change helps us understand the warming climate. Scientists have developed a new model to predict the sea ice minimum extent, using historical measurements and real-time satellite data. The model can begin predictions up to six months before the predicted minimum and continue to improve each day.

2012 Global Temperature Anomalies
 
01:22
According to the NOAA scientists, 2012 was the 10th warmest year since records began in 1880. The annual global combined land and ocean surface temperature was 0.57°C (1.03°F) above the 20th century average of 13.9°C (57.0°F). This marks the 36th consecutive year (since 1976) that the yearly global temperature was above average. Currently, the warmest year on record is 2010. Including 2012, all 12 years to date in the 21st century (2001-2012) rank among the 14 warmest in the 133-year period of record. This preliminary analysis is prepared by scientists at NOAA's National Climatic Data Center in Asheville, N.C., and is part of the suite of climate services NOAA provides government, business and community leaders so they can make informed decisions. The Northern Hemisphere experienced warmer than average temperatures throughout the year whereas the much of Eurasia experienced cooler temps, especially in January and February when the worst cold snap in 26 years killed hundreds of people in a dozen countries. Northeastern Brazil experienced a drought in the first half of the year and 65% of the U.S. experienced an agriculturally affective drought in the second half. Arctic Sea Ice hit an all-time record low in September with only 24% of the Arctic Ocean covered in ice. La Niña continued through 2012 and shifting to a neutral ENSO pattern by the end of the year. This dataset uses surface observations from thousands of ground and ocean stations around the globe. Those daily values are analyzed and compared to the climate average on a monthly basis. An annual composite is created using the 12 monthly composites to create an annual average temperature anomaly. This dataset contains thirteen frames, the average temperature anomaly map for each month, plus the average temperature anomaly map for the entire year.

Runaway Change in the Arctic?
 
52:40
Runaway Change in the Arctic? Extreme 2016 Temperatures. Presentation by Dr. James Overland (NOAA/PMEL) and Muyin Wang (JISAO/UW). A new Arctic surprise (unexpected magnitude of rapid change) was extensive record warm Arctic temperature extremes in January–April 2016, which repeated in fall-early winter 2016-7. In January, the Arctic-wide average temperature was 2.0° C above the previous positive record of 3.0° C above normal, with local January values in excess of 7° C above normal. Record sea ice extent losses were observed for all months of 2016 except during the summer. Sea ice multi-year (MY) fraction (amount of old thick ice) had a sharp drop between January 2016 and January 2017, and was 60% below the MY fraction during the early 2000s. Delayed sea ice freeze up in fall 2016 helped to maintain the warm temperatures, a clear example of Arctic specific feedback processes that amplified the rate of change. An open question is whether there will be continuing near future rapid Arctic changes from such surprises.

How salty is the Arctic Ocean?
 
00:49
The Arctic Sea monthly salinity climatology is animated at the surface, 100m, 500m and 1000m. Images are downloaded from NOAA/NODC/OCL (http://www.nodc.noaa.gov/OC5/regional_climate/arctic/). The Arctic Ocean is an area of intense activity both for environmental and commercial interests. Climate change has disproportionally affected this region with rising ocean temperatures and continued loss of summer sea ice extent. Oil and mineral exploration and exploitation are occurring and intensifying. To facilitate study of the region, NOAA-NODC Regional Climatology Team1 developed a new set of high-resolution long-term mean surface/subsurface temperature and salinity fields. These mean fields incorporate a great deal of data not previously available.

Arctic Ocean - Video Learning - WizScience.com
 
02:37
The "Arctic Ocean" , located in the Northern Hemisphere and mostly in the Arctic north polar region, is the smallest and shallowest of the world's five major oceanic divisions. The International Hydrographic Organization recognizes it as an ocean, although some oceanographers call it the "Arctic Mediterranean Sea" or simply the "Arctic Sea", classifying it a mediterranean sea or an estuary of the Atlantic Ocean. Alternatively, the Arctic Ocean can be seen as the northernmost part of the all-encompassing World Ocean. Almost completely surrounded by Eurasia and North America, the Arctic Ocean is partly covered by sea ice throughout the year . The Arctic Ocean's surface temperature and salinity vary seasonally as the ice cover melts and freezes; its salinity is the lowest on average of the five major oceans, due to low evaporation, heavy fresh water inflow from rivers and streams, and limited connection and outflow to surrounding oceanic waters with higher salinities. The summer shrinking of the ice has been quoted at 50%. The US National Snow and Ice Data Center uses satellite data to provide a daily record of Arctic sea ice cover and the rate of melting compared to an average period and specific past years. For much of European history, the north polar regions remained largely unexplored and their geography conjectural. Pytheas of Massilia recorded an account of a journey northward in 325 BC, to a land he called "Eschate Thule," where the Sun only set for three hours each day and the water was replaced by a congealed substance "on which one can neither walk nor sail." He was probably describing loose sea ice known today as "growlers" or "bergy bits;" his "Thule" was probably Norway, though the Faroe Islands or Shetland have also been suggested. Early cartographers were unsure whether to draw the region around the North Pole as land or water . The fervent desire of European merchants for a northern passage, the Northern Sea Route or the Northwest Passage, to "Cathay" caused water to win out, and by 1723 mapmakers such as Johann Homann featured an extensive "Oceanus Septentrionalis" at the northern edge of their charts.

Fresh Water in the Arctic -- Changing Planet
 
05:19
Scientists are concerned that melting Arctic sea ice will increase the amount of fresh water in the Beaufort Gyre, which could spill out into the Atlantic and cause major climate shifts in North America and Western Europe. The Changing Planet series explores the impact that climate change is having on our planet, and is provided by the National Science Foundation (http://science360.gov/series/Changing+Planet/) & NBC Learn (http://www.nbclearn.com/changingplanet) For related lesson plans, visit the Windows to the Universe project team at the National Earth Science Teachers Association at http://www.windows2universe.org/earth/changing_planet
Arctic Sea Ice from January 1, 2013 to September 10, 2016
 
03:03
Satellite-based passive microwave images of the sea ice have provided a reliable tool for continuously monitoring changes in the Arctic ice since 1979. Every summer the Arctic ice cap melts down to what scientists call its "minimum" before colder weather begins to cause ice cover to increase. The first six months of 2016 have been the warmest first half of any year in our recorded history of surface temperature (which go back to 1880). Data shows that the Arctic temperature increases are much bigger, relatively, than the rest of the globe. The Japan Aerospace Exploration Agency (JAXA) provides many water-related products derived from data acquired by the Advanced Microwave Scanning Radiometer 2 (AMSR2) instrument aboard the Global Change Observation Mission 1st-Water "SHIZUKU" (GCOM-W1) satellite. Two JAXA datasets used in this visualization are the 10-km daily sea ice concentration and the 10 km daily 89 GHz Brightness Temperature. In this visualization, the daily Arctic sea ice and seasonal land cover change progress through time, from January 1, 2016, through September 10, 2016 when the sea ice reached its annual minimum extent for the year. Over the water, Arctic sea ice changes from day to day showing a running 3-day minimum sea ice concentration in the region where the concentration is greater than 15%. The blueish white color of the sea ice is derived from a 3-day running minimum of the AMSR2 89 GHz brightness temperature. Over the terrain, monthly data from the seasonal Blue Marble Next Generation fades slowly from month to month. Credit: NASA's Scientific Visualization Studio.

Autonomous probes for measuring deep Arctic Ocean currents
 
03:50
Jari Krützfeldt, a student in Naval Architecture at KTH Royal Institute of Technology, will board an icebreaker bound for the icy waters at the mouth of the Greenland's Petermann Glacier. His mission is to drop 10 deep-water probes to the bottom of the Arctic Ocean, barely 1,100 km from the North Pole. Krützfeldt is part of a team that is developing and testing cost-effective, autonomous systems for long-term measurements of conditions at the seabed, mainly in polar regions. The probes he is bringing to the Arctic are designed to endure five years at a depth of 1,000m after deployment. The bottom landers will never been seen again after Krützfeldt lowers them into the water, but they will be heard from. Each probe will rest at the bottom of the ocean, collecting water temperature data that will help to improve prediction models for future sea level rising, he says. Greenland's glaciers, including the Petermann Glacier, are believed to be melting due to the flow of warm, salty deep ocean currents into the Greenland fjords. "We want to test the landers under realistic conditions and investigate these deep ocean currents," Krützfeldt says. "There is uncertainty about the rate at which the glacier is melting, and this project will provide a way to collect the data needed to predict the process," he says. "And it does it at a low cost. The project needed probes with cheap moorings that no one had to come back for to collect." The bottom landers are programmed to rise toward the ocean's surface, one by one, at different times over the next year. When each one reaches the surface, it then transmits its data via satellite to a lab at KTH. The idea is to get a time-lapse picture of the changes in water temperature that may be caused by the deep ocean currents of warmer, salty water. Once at the surface, the probes will drift with the current, sending out their positions regularly and collecting data about surface current direction and velocity.

What Would Happen If All Ice On Earth Melted?
 
11:41
What Would Happen If All Ice On Earth Melted? ► Subscribe: https://goo.gl/r5jd1F Many people have wondered what would happen if all the glacial ice on the planet melted. Some believe that it would be a water world with no land in sight, while others think that could never happen. But the Earth is changing in more ways than you might think on its own. Many might wonder how much of the Earth’s current global warming trend is affected by humans. Regardless of who is to blame, whether the planet is just going through a natural phase in its evolution, or if we are responsible, the evidence shows that the planet is getting warmer and warmer every year. But just how much of the planet could end up covered in water if all the glacial ice melted? The Arctic isn’t the same as it was today as it was, say… 100 years ago. Temperatures there have been rising at twice the normal rate which has been sparking some very alarming changes unlike anything seen in recorded history. 87% OF Antarctica Peninsula Glaciers have melted since 1945. Now the regions sea ice is declining by 13% percent each decade. Scientific predictions that foresaw an ice-free Arctic Ocean during the summer between 2040 and 2050 may come to pass even sooner than we thought. A lot of people will think ‘well that’s no big deal… just get everyone to move to higher ground’. Sounds like a simple solution. However, aside from the fact that billions of people would be displaced, there would be more to worry about now that all the Arctic ice has melted. What is not commonly known is that the Earths’ poles not only get less direct sunlight than lower latitudes, but the sea ice is white, and therefore reflects most of the sunlight that hits it back out into space. That reflectivity called ‘albedo’ helps keep the poles cold and limits the heat absorption from the Sun. But that’s not all. Scientists have known for a long time that the Arctic tundra and marine sediments contain large frozen deposits of methane gas which, if released into the atmosphere, will increase greenhouse gases. So as the Arctic Sea ice melts, this source of methane will increase. Think runaway greenhouse effect which likely helped destroy the atmosphere on Mars along with the solar winds that stripped the planet of its atmosphere. But that’s not all. During this time there could be massive Earthquakes if the ice melted fast enough. One of the more uncommonly known things is that all that ice has some serious weight and suppression to it, and it has been holding down the Earth, and global warming has already bled the frigid continent of about 2.7 trillion tons of ice with over half those losses occurring in the last 5 years. Most climate scientists agree the main cause of the current global warming trend is human expansion of the greenhouse effect… warming that results when the atmosphere traps heat radiating from Earth toward space. Some of the things you can do are to buy anything reusable and be conscious of garbage and waste and try to recycle everything. Saving gas by walking more or taking the bus can help, as well as planting trees. But it takes more than just a handful of people to make a change, it takes everyone to make an impact. Perhaps humanity will embrace this global threat on our planet and governments will act fast enough to possibly reverse the damage. And for those people who procrastinate, the time for action is now…because we just may have an ally in our own Sun… We hope you enjoyed the video.

Arctic Temperature Amplification Mechanisms
 
15:01
Rapid climate change on Earth does not change everywhere at the same rates. Since 1950, the Arctic heating pace is double that of the global average. HOWEVER, more recently, according to US CLIVAR (Climate Variability and Predictability), the Arctic has been warming SIX times faster than the global average. Mostly, this is due to darkening of the Arctic, from exponentially declining sea-ice and snow cover, but there are additional feedback mechanisms as well that I discuss here.

The Arctic Heat Open Science Project (http://www.pmel.noaa.gov/arctic-heat) deployed a series of experimental floats and other instruments from a specially-outfitted NOAA Twin Otter aircraft in June 2016. Read more about each instrument shown in the video below. ALAMO = Air Launched Autonomous Micro Observer Launched from an aircraft, ALAMO floats are programmed to complete four or more profiles daily, generally recording depth, temperature, salinity, and position. Four floats were deployed in the June 2016 deployment period; two in the Chukchi Sea and two in the Beaufort Sea. Along with the experimental ALAMO floats a number of traditional atmospheric and oceanographic probes were launched from the NOAA Twin Otter for the first time: AXBT = Aircraft Expendable Bathythermograph An oceanographic instrument deployed from an aircraft, an AXBT takes a single temperature/depth profile as it drops from the ocean's surface to the seafloor. 7 AXBTs were deployed in this series in the Chukchi and Beaufort Seas. AXCTD = Aircraft Expendable Conductivity-Temperature-Depth Profiler A profiling instrument deployed from an aircraft, an AXCTD takes a single profile from surface to seafloor, recording temperature and salinity versus depth. 5 AXCTDs were deployed in this series in the Chukchi and Beaufort Seas. Also deployed, but not pictured: dropsondes Launched via aircraft at higher altitudes, dropsondes collect an atmospheric profile as they fall to the sea surface, recording position, altitude, temperature, relative humidity, barometric pressure, and wind alamspeed/direction. Dropsondes collected similar data as a weather balloon.

Journey to the Arctic - TechKnow
 
24:19
The Arctic is warming up at twice the rate of the rest of the globe. Summer sea ice has receded by almost 25 percent since 1979, with the sea change becoming ever more apparent and Arctic-native animals now visibly struggling in their prolonged search for shelter, ice and food. Offshore oil exploration and increased tourism have also contributed to the speed at which environmental changes are occurring in the Arctic, with the fear of an ice-free summer on the horizon looming over the fate of the area. These changes have also been spotted on land, with melting permafrost causing entire patches of land and man-made structures to sink as the earth softens. Proximity to land and resources also presents a challenge, not only in times of emergency on the water, but also in executing the research required to understand and attempt to combat the effects of global warming on the Arctic. This is where the Polar-class icebreakers factor in. The United States owns only two icebreakers that are able to breach the density of ice formations the Arctic is known for. Weighing it at 16,000 tonnes and with the abilitiy to reach 30,000 horsepower, they are a force to be reckoned with on the open seas. These vessels are used not only as a coast guard, but also to aide in sceintific studies. Missions often include unmanned vehicles - a safety precaution - including drones and others that explore not only the view from the air, but also what is happening in the water and life under the ice. Levels of carbon dioxide in the air and the sea, water salinity, temperature, oxygen and chlorophyll blooms - a potentially dangerous situation where algae multiplies and decomposes on the surface of the water, using up oxygen resources from the rest of the sealife - are all deliverables that can be quantified using the unmanned vehicles. Scientists from the Arctic Domain Awarness Centre at the University of Alaska Anchorage are also working on an 'isotope sniffer' amongst other experiments and unmanned 'drones'. A snout hangs out from the bow of a Polar-class icebreaker as a means of atmospheric sampling, and feeds the information down to isotope analysers below deck, in seconds-long intervals. The ultimate vision is to understand the effects of potentially environmentally-damaging activity, such as offshore rigging by the Shell oil company, creating technology that can accurately register important data in extreme temperatures and conditions - 'guardians' of the water - without endangering the lives of crew members. - Subscribe to our channel: http://aje.io/AJSubscribe - Follow us on Twitter: https://twitter.com/AJEnglish - Find us on Facebook: https://www.facebook.com/aljazeera - Check our website: http://www.aljazeera.com/
