Full length NSIDC Sea Ice Data

Posted by Jeff Id on January 17, 2012

Below is the full length of the NSIDC SEA ice data. From 2.8 gb of data. The graphs of the Arctic and Antarctic are plotted on equal grid scales having a pixel resolution of 25km. The satellite ice data comes from the NSIDC Sea Ice Concentrations as collected from the Nimbus-7 SMMR and DMSP SSM/I Passive Microwave systems.

    I recall quite a kerfuffle in the media about part of the Ross ice shelf breaking away one Antarctic summer. This video appears as though it is on thin ice every year.

  3. Thanks, Jeff.

    Video images of reality like these are an affront to the fictitious models of reality promoted by world leaders and their armies of well-funded consensus scientists.

    Inability to defeat reality has perhaps convinced them to try to close down the only remaining channel of open communications – the web.

    These are always fun to watch.

    Is there any way you can break them into two separate videos; it’s hard to watch the two at the same time.

    Whatever happened to all those vector videos you made a few years ago. Do you still have them and can you put them up?

    Take care, all. Sylvie says “Woof!”

    Someday we’ll have a nice 9-mo. Cdn NWP. No luck yet, though.

    Watch the lakes in the lower right of the left frame. They never ice over completely, but show flickers all year round, even July-Sept!

  6. Jeff,

    I cannot stress enough the importance of your video showing undeniable visual proof of continuous, cyclic expansions and contractions of sea ice!

    World leaders, Al Gore and the UN’s IPCC did NOT LIE in reporting sea ice is melting. They reported one part of the experimental facts. They deceived by failing to report the other part: Sea ice is also freezing.

    Today they are trapped, like rats on a sinking ship, by four decades of deception:

    And an international web of factual information – like your videos – that documents undeniable experimental facts that contradict government deception:

    1. Neutron repulsion in the Sun’s pulsar is Earth’s primary heat source and almost certainly the primary energy source of the expanding cosmos.

    2. Hydrogen is a by-product, not primary fuel, of the Sun and other ordinary stars.

    3. The Sun’s Fe-rich mantle and H/He-rich atmosphere moderate energy pulses.

    4. Earth’s air and oceans also protect against abrupt changes in temperature.

    Today world leaders are struggling to control public protests on the left (Occupy Wall Street), the right (Tea Party), and the middle (Wikipedia blackout)

    While the World Bank finally admits a global slump in economic growth:

    The world is unstable because world leaders cannot change reality to fit their fictitious models and bars of false pride and arrogance have them locked in ego cages – like rats trapped on a sinking ship.

    Very nice Jeff! It’s interesting the way the sea ice around Antarctica appears to circulate clockwise.

    Jeff;
    Nice of you to allocate one of your ‘big machines’ to grind through this huge rendering job. Having tried some of these, I know that it is a non-trivial task.
    In my experience, if you interrupt a graphical rendering once started, you lose all the work and have to restart again. Ugh…

    From a ‘visual’, ‘perceptual’ perspective, my impression is that minimum Antarctic sea ice is less than minimum arctic ice. Perhaps this is due to the summer ice being spread around the large brown static chunk in the middle of the southern image, vs. the artificial blue dot of non-coverage. Here I mean that the same amount of icing might seem to be less because it is spread thinner around a larger central cake.

    I guess that ‘ice extent’ must include the non-sea ice down south, no?

    Interesting that the AntArt melting starts adjacent to that section ~6 oclock on the image, adjacent to the continent, and proceeds away from the land mass. Apparently some underwater current is ‘upwelling’ there?

    An semi-related question; how long have we had the ability to measure the ice mass sitting on the continent itself? (I assume that ‘GRACE’ can now do it, yes ?)

    If the AA ice extent trend is ~increasing, does that say that the AA ice mass might be increasing also?

    Jeff ID, it appears to me that an important source the summer ice extent loss comes from land-influence from Eurasia.

    Is that your impression too?

    #9 I’m rethinking everything about it now. There is a news article which stated that there are some ocean currents which are so warm that even in minus 50 weather the surface isn’t freezing. I really want to overlay brightness temps on the graphs and flow vectors.

  11. Richard said

    #10. Salinity as well as that has a significant effect on where the ice can/will form.

    Jeff, #10:

    Overlaying SST (when available) is a great idea.

    Those are the great lakes and a victim of bad (cloud confusion, maybe?) data for at least the summer months. July 24, 1983, for example, has most of Lake Michigan frozen over, when in face it was at 0%. It would have been in error to have any of that lake covered for around 45 to maybe 60 days in either direction from that date.

    Oops!

    *when in fact is was…
    *any of that lake ice covered for..

  15. Brian H said

    Yes, obviously they are; I wasn’t getting the polar viewpoint at first. ;)
    But if ice data is cloud-corrupted there, why not elsewhere?

    I had the same thought.

    Anyone watching this who thinks we are suffering from a a catastrophe is seeing what they want to see.

  18. […] Earth.    The lines in the southern hemisphere give an interesting reference but you can confirm from video that the Antarctic sea ice melts almost completely every year. Figure 4. Mollweide projection. Equal area per […]
