Speaking to The Independent about the record-breaking data, climate scientist Martin Stendel of the Danish Meteorological Institute said “the temperature anomalies in the high Arctic … Remember how the ice bed-wetters got all stirred up by the storm that broke up and transported all the ice in 2012. “This is going to be a winter to remember,” concludes Mauriello. Each file is named according to the following convention: Where YYYY is the 4-digit year and MM is a 2-digit month of the chart. In all, there are 266 image files containing 291 images. We know how guesses turn out ! However, DMI still has tthis absurd item posted on it’s website: During the past 10 years the melting of sea ice has accelerated, and especially during the ice extent minimum in September large changes are observed. I’m not criticising, I’m just saying to be very careful how you use linear trends on cyclic graphs. See the note on reliability for further discussion of potential error. For example, the file 1893_04-09.jpg contains a composite of the data from April through September of 1893. Dehn, W. S. 1979. The melt ended and the ice began building in the third week of August, taking with it the apocalyptic prophesies of many a MSM shill. These charts provide a pan-Arctic view of sea ice extent covering the Arctic Ocean from approximately 55° N to 90° N. The charts span 1893 - 1939 and 1946 - 1956. Read their blog ... Icelights: Answers to your burning questions about ice and climate. Scientists blog from Antarctica and provide a glimpse of what it's like to do research in the field. According to NSIDC Arctic sea ice extent dropped by 73,000 km^2 yesterday, some of which is above 80ºN. Currently his graph shows a slight linear increase in volume whilst your graph shows it to be more level. I guess that means you would prefer not to upset Tony rather than your graph be correct? It starts at roughly 16,000km3 about Jan.1, 2008 and ends at roughly 23,000km3. Graphically , except I use Mkm³ on the y axis, Sorry, I forgot to add e+13 to the figures above. These ice types have been converted into approximate percent-coverage values (See Tables 1 and 2). Since the DMI ice volume decline this year is only about half the average decline, I expect That 2018 will rise above those years in the next few days, Making at #4 for the date . Looking for facts and information? Walsh. In 2011, the ice edge position was traced on scanned charts in order to obtain the ice edge position at a higher resolution than has previously been possible. https://wattsupwiththat.com/2017/12/case-closed-malicious-wuwt-troll-sees-police-show-up-at-his-door/. Arctic sea ice volume prooves the new ice age theory..oops,my fault.I forgot they traded the ice age scare for global warming in the meantime(without any resistance or discussionfrom the ice age climate scientists as your global warming scientists have been your ice age scientists.They just changed their minds 180 overnight the same way hundreds of german nazi scientists changed not just their minds and ideologies but also citizenships when they were secretely imported to the USA via operation paperclip). Looks like it will fail to transport much sea-I e down through Fram Strait. Note: The September ice is often depicted for some regions on the same chart as August. To quote from the movie JAWS….”your gonna need a bigger torch”. Trausti Jonsson, IMO, encouraged us to use the collection he had scanned. Jimmy I searched on line for more info on what has happened with Reggie since the Dec 2017 news and found squat but that was about a month ago. yet. Then look at the 2008 graph. This was done at a resolution of 100 km, beginning with the 1901 chart. The first use of these charts in digitized format was in the late 1970s when P.M. Kelly, at the University of East Anglia, digitized the ice edge in a set of the charts (Kelly 1979). The Danish Meteorological Institute (DMI) presents ice maps. ! For the 1893 and 1894 charts, a composite chart was created from all of the summer months. Monthly coverage varies slightly from year to year, though for most of the record, charts cover April through August. Danish Meteorological Institute Notify me of follow-up comments by email. Are you saying your graph is incorrect and Tony’s is correct? Weird.. little andy-trollette thinks the North Pole isn’t above 80ºN !! Beginning in 1900, these observations were collated and published annually in reports entitled "The State of the Ice in the Arctic Seas." The months included in the image are listed sequentially in the filename. — Richard Feynman. It will be fun watching the ice-worriers over the next few years. The DMI later attempted to retroactively publish information from these years (Kelly 1979), but we do not possess scans of those charts and have no further information. National Snow and Ice Data Center, "Glaciological Data, Report GD-2", part 1, pp. Various DMI ice-maps are available on their web (see dates as links below the main map). World Data Center A for Glaciology (Snow and Ice). So any way you can, help us spread the message so others can survive and thrive in the coming times. http://woodfortrees.org/plot/sine:10/from:1955/to:1993.5/plot/sine:10/from:1955/to:1993.5/trend. Sea ice maps from the Danish Meteorological Institute. Ed. Ocean and Ice Services | Danmarks Meteorologiske Institut. Some may say, so what? Details on areas of open water can be found in the notes that accompany the charts. As suggested by Kelly (1979), the map makers probably extrapolated the annual ice edge in three ways: they probably used their knowledge of ice movement, growth, and melt to project ice conditions from given data points further in both time and space. Figure 2 shows examples of the charts from the early, mid, and late parts of the program and illustrates differences in the legends. This site uses Akismet to reduce spam. In most cases, this assumed ice edge follows a 30-year climatological average over a period of years that shifts over the record. Compiled by V. Underhill and F. Fetterer. Activities are presented thematically and heavily cross-linked below in order to provide easy access to people, projects, publications or possible collaboration opportunities. And after closely tracking the current trend, Mauriello’s prediction is for the Arctic circle to be all-but covered in ice within the next 4-6 weeks. Barry, R. 2000. Glaciological Data Report : Workshop on Snow Cover and Sea Ice Data. The process for defining these percentages is described in the Arctic Sea Ice Concentration and Extent from Danish Meteorological Institute Sea Ice Charts, 1901-1956 data set. ;-), What I’m saying is that your DMI trend graph should look like this. I’ve been going round and round with them, via email, for about a month and a half now. From 1946 to 1956, the ice edge in this region solely reflects annual climatology; the DMI probably did not have access to any data in this region because of the Cold War. Coverage is considerably better over Greenland, Iceland, and Spitzbergen than for the rest of the Arctic, and direct observations over the Western Arctic are particularly sparse over the entire period of record. No FAQs or How Tos available for this data set. The number of charts ranges from 1 to 6 per year depending on the year. In the first graph he shows, sea ice volume starts out at roughly (eye balled) 17,000km3 around the first of Jan and goes up to roughly 23,000km3 on Mar. What is the calculated linear trend on this graph…, hint: the graph is obviously heading downwards, isn’t it ?? Late summer Arctic sea ice –the most closely watched measure of the state of the northern pole– has been incredibly stable over the past few decades, and is now showing signs of GROWTH. Int. The reports have a summary with detailed information for particular regions where ship traffic was concentrated, and charts showing ice conditions as observed, or, when observations were not available, inferred ice extent. Beginning in 1951, the DMI charts began using a standard terminology as set forth by the World Meteorological Organization (WMO). This year is still #6, but approaching the next two years above it rapidly. We consulted members of the International Ice Charting Working Group (IICWG) when building the table of inferences concerning ice concentration nomenclature (Table 2). Gridded ice concentration was estimated as well. It is exactly what I intended to plot. It shows Arctic sea ice has done NOTHING. Documenting Earth Changes during the next GSM and Pole Shift. On Thin Ice: All charts are plotted on a polar stereographic projection. The % Uncertainty column contains the assumed uncertainty in these concentrations in percent. When scientists talk about the cryosphere, they mean the places on Earth where water is in its solid form, frozen into ice or snow. You are only fooling yourself. I luv the way U Marshall Your Real Data (- Called FACTS-) Steve that basically Crushes All the Climate Modelers into the Ground! If a single corresponding ice concentration number is needed, one may use the number in the % Concentration column. These charts, created by the Danish Meteorological Institute (DMI), provide observed and inferred sea ice extent for each summer month from 1893 to 1956. The % Uncertainty column contains the assumed uncertainty in these concentrations in percent. The yearbooks also contain narrative ship reports of sea ice for the winter months. I don’t follow Hansen AndyG55, not read anything of his stuff. See About the Cryosphere. It will test many ideas. For more information, see our Use and Copyright Web page. Your #1 prophet says the Arctic will be ice-free in a few weeks. Data on the Geographical Distribution of Sea Ice. Kelly's digitized version was later incorporated into larger data sets, notably Chapman and Walsh (1991), but also see Walsh (1978) and Sear (1988). Diagrams showing Arctic sea ice extent 8 October 2019 (left) and 2020 (right) and the seasonal cycles of the calculated total arctic sea ice volume, according to The Danish Meteorological Institute (DMI). According to the NSIDC, ice has remained in The Northwest Passage this year despite the decades of dire forecasts, as has the ice in areas north of Alaska within the Beaufort and Chukchi Seas despite NSIDC forecasts from just a few months ago. Finally, we thank the Danish Meteorological Institute and its library for recognizing the importance of systematic collection of sea ice information very early on, organizing the effort internationally, and freely sharing the published reports that resulted. J. Climatology 8(4): 339-55. However, a lack of funding limited his work to digitizing the ice edge only. 2013. Data on the Geographical Distribution of Sea Ice. The DMI map makers were experienced climatologists, so while their inferences are subjective, they are also probably the most reliable of the time. Where do I say the North Pole is not above 80N? So very embarrassing for Hansen and all his followers, like you. The site receives ZERO funding, and never has. J. of Glaciology 1(3): 140-141. Inadequacies in Archive Sea Ice Data. The early history of this collection is described in Thomsen (1947). Nice work, but please consider, (and note that I am no expert…) that arctic ice is also subjected to wind action which can blow bodies of ice south where it melts in the warmer waters south of the arctic circle. That is a separate entity with its own graph and data. All 291 charts in the 266 .jpg files reside in a single directory on the NSIDC FTP site: ftp://sidads.colorado.edu/DATASETS/NOAA/G02203/. In order to get a true picture of the state of sea ice it is necessary to determine both its extent AND its volume, reads the DMI’s polarportal.dk. A June storm will be churning the sea-ice as it moves up from the Kara Sea coast to the Pole this week. Home | Contact Us© 2020, National Snow and Ice Data Center :: Advancing knowledge of Earth's frozen regions, Converting the sea ice chart information to digital format.
