Each year's line traces sea ice extent over the calendar year, starting high in January, rising through the time of the winter maximum around late March, declining through mid-September, and. The Arctic Sea Ice Graphs web site. In addition here are some additional graphs and maps focussing on Arctic sea ice thickness and volume that are difficult to update automatically. We shall endeavour to do so manually as and when time allows. JAXA/UH Arctic Sea Ice Area/Extent. Following the sad demise of the SSMIS instrument on the DMSP F-17 satellite, here's Arctic sea ice area and extent. For the Arctic, the median July Outlook for September 2020 average sea-ice extent is 4.36 million square kilometers, essentially identical to the median prediction in the June report, with quartiles of 4.1 and 4.6 million square kilometers. For comparison, the historical record September low over the period of satellite observations was set in 2012 at 3.57 million square kilometers, and the.
This graph shows the average monthly Arctic sea ice extent each September since 1979, derived from satellite observations. The animated time series below shows the annual Arctic sea ice minimum since 1979, based on satellite observations. The 2012 sea ice extent is the lowest in the satellite record Every summer, the Arctic ice cap melts to what scientists call its minimum before colder weather begins to cause ice cover to increase. This visualization shows the expanse of the annual minimum Arctic sea ice for each year from 1979 through 2019, with a graph overlay. In 2019, the Arctic minimum sea ice covered an area of 4.15 million square. The graph above shows Arctic sea ice extent as of October 4, 2020, along with daily ice extent data for four previous years and the record low year. 2020 is shown in blue, 2019 in green, 2018 in orange, 2017 in brown, 2016 in purple, and 2012 in dashed brown. The 1981 to 2010 median is in dark gray. The gray areas around the median line show the interquartile and interdecile ranges of the data. The sea ice cover is one of the key components of the polar climate system. It has been a focus of attention in recent years, largely because of a strong decrease in the Arctic sea ice cover and modeling results that indicate that global warming could be amplified in the Arctic on account of ice-albedo feedback. This results from the high reflectivity (albedo) of the sea ice compared to ice. Arctic sea ice. Area, extent, volume, thickness, ocean, atmosphere.

Arctic Sea Ice Status: Going. Going. Soon to be Gone // Sep 3, 2020 In this first of a new series of videos I chat about Arctic Sea Ice. We are approaching the yearly minimum, and it is a toss up as to whether or not we will set a new record, beating out 201 Arctic sea ice coverage contracted to a minimum of 3.74 million square kilometers, the second lowest in 42 years of record Another month has passed and so here is the updated Arctic sea ice volume graph as calculated by the Pan-Arctic Ice Ocean Modeling and Assimilation System (PIOMAS) at the Polar Science Center: During October there was a slowdown in ice growth, which is also reflected in the PIOMAS numbers. 2019 was the third year since 2007 to record a volume increase under 2000 km3 Arctic sea ice extent in January 2020 is sitting ABOVE levels observed in the years 2019, 2018, 2017, 2016, 2015, 2012 (record low extent), 2011, AND 2010.. Can you imagine the likes of The Guardian, for example, ever running with this? The source of the data isn't some hokey-pokey conspiracy site — it's America's NSIDC, who boast being backed-up by NASA-and they have satellites and.
Arctic sea ice today is more extensive than for most of the Holocene, ie the past 11,400 years. MarkW says: July 30, 2020 at 9:57 am When griff decides to lose his mind, he does it in a grand fashion. At least griffie poo is finally admitting that ice levels were lower 10K years ago. For years he's been claiming that ice levels are the lowest in history. In fact I believe he made that claim. Weekly Animation of Arctic Sea Ice Age with Graph of Ice Age By Area: 1984 - 2016. Visualizations by Cindy Starr Released on October 28, 2016. There is a newer version of this story located here: https://svs.gsfc.nasa.gov/4750. One significant change in the Arctic region in recent years has been the rapid decline in perennial sea ice. Perennial sea ice, also known as multi-year ice, is the. The data from years 2002-2018 are also available at the data publisher PANGAEA, one data set each for Arctic and Antarctic, AMS-E-based and AMSR2-based: Melsheimer, Christian, Spreen, Gunnar (2020): AMSR-E ASI sea ice concentration data, Arctic, version 5.4 (NetCDF) (June 2002 - September 2011)

The data is based on DMI 's model calculations. The map is updated on a daily basis. In order to get a true picture of the state of the sea ice, it is necessary to determine both its extent and its volume. This includes the thickness of the ice, which can vary. The sea ice satellite record dates back to October 25, 1978. Unlike the Arctic, where sea ice extent is declining in all areas in all seasons, Antarctic trends are less apparent. From 1979-2017, Antarctic-wide sea ice extent showed a slightly positive trend overall, although some regions experienced declines. Those exceptions have occurred. This visualization shows the age of the Arctic sea ice between 1984 and 2019. Younger sea ice, or first-year ice, is shown in a dark shade of blue while the.
In 2019, the Arctic minimum sea ice covered an area of 3.66 million square kilometers. This visualization shows the expanse of the annual minimum Arctic sea ice for each year from 1979 through 2019 as derived from passive microwave data. A graph overlay shows the area in million square kilometers for each year's minimum day Graphic: Arctic sea ice loss In the summer of 2012, the floating cap of sea ice in the Arctic Ocean shrunk the smallest area ever recorded in the satellite era, which begins in the late 1970s. In fact, the ice cap melted to an extent less than half of what it was at the same time of year in 1979, making it one of the most dramatic and visible signs of climate change
The ice in the Arctic is melting. That's bad. The Arctic Sea Ice is often referred to as one of the planet's air conditioners, because it keeps things from heating up too much. But as. Following up on @Neven's comment about the lack of a model behind these graphs: it does seem to me to be possible to connect our models of Arctic sea ice to these graphs. Skipping a lot of argument: the combined effects assumed in a PIOMAS-type model would result in volume that initially (up to now) fits the gompertz curve. The resulting pack of curves would posit (linear or exponential. . But thanks to a wild-ass, record-breaking heat waves in the Earth's northernmost regions, this year's minimum ice extent is anything but normal.. The National Snow and Ice Data Center's data shows that on Sept. 15, Arctic sea ice likely reached its annual minimum extent of 1.44 million square miles (3.74. The most visible change in the Arctic region in recent years has been the rapid decline of the perennial ice cover. The perennial ice is the portion of the sea ice floating on the surface of the ocean that survives the summer. This ice that spans multiple years represents the thickest component of the sea ice cover. This visualization shows the perennial Arctic sea ice from 1980 to 2012 UPDATE: View the updated version of this visualization: https://www.youtube.com/watch?v=KtWTZIFgL_w This visualization shows the weekly age of the sea ice be..
Arctic sea ice reached its summer minimum for 2020 in mid-September, which is now logged as the 2nd lowest extent seen in over 40 years. Each year, as the seasons wax and wane, sea ice across the. This graph shows how Arctic sea ice is at low levels when compared to previous years Credit: .NSIDC Researchers from the University of Massachusetts Amherst recently published an article in The Conversation explaining how carbon dioxide levels in the atmosphere are higher than at any other time in human history

Schneider, NCAR) Comparison of September Arctic. A graph in the lower, right corner the quantifies the change over time by showing each age category of sea ice as a percent of total ice cover in the Arctic Ocean. The lavender outline on the map indicates the spatial region covered by the Arctic Ocean and thus included in the graph. Correction: The original release on 10/28/2016 incorrectly labeled the oldest category on the graph as 5.
The image above shows melting of Arctic sea ice extent over the last 20 days, July 5 to 25, 2020. At the bottom right, the shallow Hudson Bay goes to water rapidly, losing 500k km2 of ice. Even so, at 172k km2 that region is nearly average. The remarkable 2020 event is the effect of high Siberian temperatures causing extensive melting of the nearby shelf seas, seen on the left vertical. sea ice; climate change; satellite Earth observations; climate trends; Antarctic sea ice; Since the late 1990s, it has been clear that the Arctic sea ice cover has been decreasing in extent over the course of the multichannel passive-microwave satellite record begun in late 1978 (1 ⇓ -3).The decreases have accelerated since the 1990s and have been part of a consistent suite of changes in. 2014 Webby Award winning website. Click each award to learn more. Information Quality; NOAA Freedom of Information Ac One significant change in the Arctic region in recent years has been the rapid decline in perennial sea ice. Perennial sea ice, also known as multi-year ice, is the portion of the sea ice that survives the summer melt season. Perennial ice may have a life-span of nine years or more and represents the thickest component of the sea ice; perennial ice can grow up to four meters thick Since 1978, satellites have monitored sea ice growth and retreat, and they have detected an overall decline in Arctic sea ice. The rate of decline has steepened in the 21st century. In September 2002, the summer minimum ice extent was the lowest it had been since 1979. Although the September 2002 low was only slightly below previous lows, it was the beginning of a series of record or near.
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. This graph displays the area of the minimum sea ice coverage each year from 1979 through 2019 Arctic sea ice — declining now for decades — has plummeted to a record-low for this time of year, particularly in the seas above Russia and Siberia A graph posted to Twitter this week shows that combined polar ice cover is shockingly out of step with normal. In the Arctic, sea ice started to form in September before taking a pause in October,..
The early June 2020 sea-ice concentration map (Figure 8, NSIDC) shows open water and low concentration ice in the Chukchi Sea, northern Baffin Bay, far northern Barents Sea, and low concentrations along the Siberian coast. The sea level pressure plot (Figure 9) for 20 May through 12 June shows a low pressure center over the northern Kara Sea and high pressure on the Canadian side of the Arctic. The Changing Face of the Arctic; The Changing Face of the Arctic - The New York Times I combined the DOE and IPCC graphs, to show what government agencies are up to. They start their linear graphs at the century maximum sea ice extent. Then fraudsters like John Cook release fake graphs like this, so that they can blame it on human activit
That's because the decreases in Arctic sea ice far exceed the increases in Antarctic sea ice. The line graphs above plot the monthly deviations and overall trends in polar sea ice from 1979 to 2013 as measured by satellites. The top line shows the Arctic, the middle shows Antarctica, and the third line shows the global, combined total. The sparklines at the bottom of the graphs show. Modeled ice thickness and volume The plots show maps with sea ice thickness, and seasonal cycles of the calculated total arctic sea ice volume. The mean sea ice volume and standard deviation for the period 2004-2013 are shown with gray. The figures are based on calculations using DMI's operational ocean and sea ice model HYCOM-CICE
Arctic sea ice cover varies substantially over the year, with end-of-winter ice cover generally being two to three times as large as at the end of summer. Sea ice is an important element of the Arctic system: (1) acting as a barrier between the underlying ocean and the atmosphere, (2) limiting the amount of absorbed solar energy during the summer due to its high albedo, (3) providing a habitat. sea ice changes from month to month and from year to year. The size of the area covered by sea ice is called the extent of the sea ice. In this activity, you will graph the extent of the sea ice over time. 1. We will start off by looking at the sea ice around the North Pole in the Arctic Ocean. Your teacher will give you a piece of graph paper
Arctic ice now just over half of extent typical in 80s. Arctic sea ice extent plummeted to a record low in 2007, stunning even veteran researchers. The crash marked a new era: No minimum since 2007 has managed to stay above pre-2007 values, and an even lower record was set in 2012 This app displays the monthly mean sea ice extent for the Arctic and Antarctic along with the historical median extent. Additionally, graphs are used to visualize the minimum and maximum extent for each year (top), and the monthly time series for each year (bottom). Use the top graph to select specific years to display in the map Trends in sea ice thickness/volume are another important indicator of Arctic climate change. While sea ice thickness observations are sparse, here we utilize the ocean and sea ice model, PIOMAS (Zhang and Rothrock, 2003), to visualize September sea ice thickness from 1979 to 2020 The most visible change in the Arctic region in recent years has been the rapid decline of the perennial ice cover. The perennial ice is the portion of the sea ice floating on the surface of the ocean that survives the summer. This ice that spans multiple years represents the thickest component of the sea ice cover. This visualization shows the perennial Arctic sea ice from 1980 to 2012 From NSIDC: The graph above shows Arctic sea ice extent on September 15, 2020, along with several other recent years and the record minimum set in 2012. 2019 is shown in green, 2018 in orange.
this post is an analysis of piomas sea ice volume 1979-2019 for the calendar months january to september. revised 11/7/2019 with thanks to andy lee robinson and to the fine people at arctic-sea-ice-graphs [link] [link to home page of this site] figure 1: sea ice volume 1979-2019: thousands of cubic km As a result of our analysis on sea ice data measured by the onboard microwave scanning radiometer, we found that the sea ice extent in the Arctic Ocean has become the smallest in observation history. The extent on August 24 (JST) was 4.21 million square kilometers, and that fell below the smallest record of 4.25 million square kilometers marked in 2007 in satellite observation history
The Arctic sea ice cover today is much thinner on average than it was years ago. Satellite imagery, submarine sonar measurements, and data collected from NASA's Operation IceBridge indicate that the sea ice thickness is as much as 50 percent thinner than in previous decades, going from an average thickness of 3.8 meters (12.5 feet) in 1980 to 1.9 meters (6.2 feet) in recent years. Older. This speculative graph shows what sea ice extent in the Arctic could look like in 2035 if these projections play out. Credit: NSIDC/Scott Sutherland. For this purpose, ice-free means that the September minimum extent for Arctic sea ice drops to below 1 million square kilometres. In such a case, sea ice would still spread to cover a wide expanse of the Arctic Ocean in northern winter and early. The graphs depict how much the sea ice concentration moved above or below the long-term average. (They do not plot total sea ice concentration.) Arctic and global sea ice totals have moved consistently downward over 38 years. Antarctic trends are more muddled, but they do not offset the great losses in the Arctic. The maps below give a closer look at the record lows that occurred at each pole. The small historical map from the beginning of the 20th century shows the distribution of Storis, or sea ice from the Arctic Ocean, which flows down the east coast of Greenland. The graphs show the reconstructed time series of changes in the occurrence of sea ice and polar waters in the past Since the end of November 2007, Arctic sea ice volume is up 15% from 13,000 km³ to 15,000 km³. There has been a huge expansion of thick ice into the East Siberian Sea. 2007 2017. Arctic sea ice extent is normal, rapidly increasing, and close to the 1981-2010 average.

According to the National Snow and Ice Data Center, Arctic sea ice cover in 2017 shrank to 4.64 million square kilometers (1.79 million square miles), the eighth-lowest extent in the 39-year satellite record. Charting these annual minimums and maximums has revealed a steep decline in overall Arctic sea ice in the satellite era. But the decline is not the same everywhere across the Arctic Ocean. The ice extent is about to drop below 4 million square kilometres for the first time in the satellite record, and the Arctic has shed almost half a million square kilometres of sea-ice in last five days! With three weeks of the melt season still to go, it's not hard to see extent dropping another half a million square kilometres (or more!) to 3.5 million square kilometres. (In previous big. False: Ice decline in Hudson Bay has been among the lowest across the Arctic. Sea ice decline in Hudson Bay (see graphs below) has been less than one day per year since 1979 compared to more than 4 days per year in the Barents Sea. Hudson Bay ice decline also uniquely happened as a sudden step-change in 1998: there has not been a slow and.
Arctic sea ice volume was 16,855 km 3 in 1979 and 3,261 km 3 in 2013. Calculate the percent change in sea ice volume for this time interval. Based on your answers to a) and b), which has seen a more dramatic change since 1979 — minimum Arctic sea ice area or Arctic sea ice volume? Explain what you think this means about the current state of Arctic sea ice and climate The ice formation got a late start and everything lagged behind - it was hard for the sea ice cover to catch up. The Arctic's sea ice maximum extent has dropped by an average of 2.8 percent per decade since 1979. The summertime minimum extent losses are nearly five times larger: 13.5 percent per decade Arctic Sea Ice Predictions Contacts, for more information: Mike Winton Mitch Bushuk Related Areas of Research: Climate Variability and PredictionArctic Sea Ice Trends and Extremes Continuous observations of the Arctic sea-ice cover have been possible since 1979 with the use of passive microwave sa.. . In 2013, the Arctic minimum sea ice covered an area of 4.704 million square kilometers. This visualization shows the expanse of the annual minimum Arctic sea ice for each year from 1979 to 2013 as derived from SSMI data. A semi-transparent graph.
The Arctic is experiencing a vast melting of sea ice. But something is happening under the ice that scientists don't fully understand 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. Arctic sea ice rebound. Next we move to the Arctic. This year's winter is seeing an impressive rebound in sea ice, tweets meteorologist Chris Martz, reaching the 3rd highest level in 15 years: Arctic sea ice extent is currently 3rd highest in the last 15 years, the only years higher are 2008 and 2009. It just surpassed 2013 and is about to. Arctic sea-ice extent for 20 August 2019 was 4.73 million square kilometers (1.83 million square miles). The orange line shows the 1981 to 2010 average extent for that day. Graphic provided by the National Snow and Ice Data Center. The current distribution of sea ice corresponds well with the departures from normal air pressure and temperature observed thus far during the summer. The first. The ice parameters derived from satellite ice concentration data that are most relevant to climate change studies are sea ice extent and sea ice area. This graph displays the area of the minimum sea ice coverage each year from 1979 through 2015. In 2015, the Arctic minimum sea ice covered an area of 3.885 million square kilometers
