Wrangel Island ice bridge no more, its a messy combination of very thin broken sea ice and Goodbye Waves


       Goodbye Waves can give a problem with determining wether they are sea ice or as they really are slush:

Goodbye Waves along with very thin emaciated ready to melt sea ice near Wrangel Island August 30, the thin ice almost looks like goodbye waves but they are not quite alike.

August 27-28 ,  JAXA depiction is fairly good ,  but there is a mix between Goodbye Waves and sea ice, seen on 28 apparently having more sea ice,  although the two are from sea ice, they are definitely not alike,  the prominent gap breaking up the ice bridge in two is more prominent on NASA EOSDIS capture (above),  the bridge is no more,  what is left is going goodbye.


JAXA got the Gap almost the same with EOSDIS  on August 29

Goodbye Waves likely caused this confusion.  Look at the 2nd arm of the ice bridge reappearing on August 28.  



The ice bridge collapsed quicker by the cuts of many cyclones,  it was already impossible to walk on
it late July.  It now exists like glue holding 2 tons together.  WD August 30,2016

Massive number of "Goodbye" waves don't appear to register on JAXA

~Gyre centred Anticyclone rearranged flow circulation,  a pause in the big extent drops were to be,  however expected to surge again very soon



  Beaufort Sea July 22 August 5 AMSR2 result.   Massive area of 'Goodbye' waves didn't really show up on JAXA which is very interesting,  it rather means that they are essentially slush,  otherwise need be confirmed as such.

  The 'Goodbye' waves of August 4 and 5 set themselves apart from sea ice in many ways,  they are likely very thin slushy sea ice remnants (with  different chemistry?),  very thin because they move faster:

   Goodbye waves are generally faster than sea ice,  as a matter of distinction and practicality, essentially excellent example on how to measure sea ice volume.  Lighter objects floating on sea surface should be swifter, especially if the sea current goes different direction than the winds .   Sea ice moves South while Goodbye waves move West...    Place your mouse pointer on Aug 3 on any large sea ice pan, and determine the distance it travelled,  notice Goodbye waves move greater distances.  WD August 6,2016

Slow melting Goodbye Waves examples

~ 78 N 176 W very slow melting made obvious by individual Goodbye Waves readily identifiable day by day.

~   The waves in this case seem to stream over fresh melted less saline colder sea water.

    This JAXA portion of melt area is very interesting,   JAXA October 4 and 5 has more sea ice than NASA captures,  that is not new,  but here we see the likelihood that Goodbye Waves are melting over less saline recently melted  sea water,  not really warmed by significant sunlight.

   There is melting,  but not so fast , October 1 to 5 NASA EOSDIS,  we look especially at left waves
breaking down slowly.  We also see a day by day variation in the main pack compacting a little but really moving,   still individual waves are recognizable,  a large contrast to not so long ago melting when the waves disappeared or were impossible to identify from one day to next.   WDOctober 5 2018

Numerous sea ice "goodbye waves" North of Northeastern Laptev Sea, Eastern Beaufort and Lincoln Sea

     More whitish sea ice"goodbye"  waves appeared through wavy clouds,  likely  under wind driven stratocumulus or altocumulus appearing slightly greyer on August 1, 2016.   They now occupy top of sea water once covered by sea ice pans July 21 past.    Break up and dispersion of once a huge solid ice field expanse,  surrounding with water its broken up smaller pieces,  accelerated the melting a great deal.  At this date there are huge number of sea ice floes surrounded by open water everywhere in the Arctic.

   Beaufort Sea comprises many drift zones, some intertwine,  South of Banks island mainly Tidal driven ice tends to move East.  Just to the west of Banks is Gyre driven to the Southwest,  the 2 give similar but orientated "goodbye waves"  according to prevailing current.  We can see the gradual rapid melt in progress, but there are still thousands of incoming ice islands from CAB to turn to water.


Lincoln Sea opening to Nares Strait has always a significant tidal (southwards) drift,  but in this case the winds, characterized by August 1 lens NW shaped Stratocumulus ,  easily push away  the sea ice Northwestwards,  note the "goodbye waves" appear the most fluid and mobile zooming like arrows with the wind.  Northern Ellesmere ice conditions are now badly broken and can easily move open for miles in less than a day,  it does so even in the dead of winter because of daily tidal activity causing the "big lead" at times , this is a good summer example.  WD Aug31,2016

Jupiter has Arctic sea ice "Goodbye Waves" , the red version

~Geophysics can be filled with symmetrical effects,  some having same or wildly differing causes
~Arctic Goodbye waves,  seen here: http://eh2r.blogspot.com/2016/09/wrangel-bridge-waves-away-goodbye.html  , are a terribly photogenic,  even artistic expressions from sea ice melting away. 
~But Jupiter is no Earth.  Or is there solids on top of its dense gaseous atmosphere?


    Thanks "New Horizons"  view here. Something on Jupiter looks familiar?  EH2r has dealt with this before:

  Although Jupiter is much more colourful,  the look is pretty much the same.  Here we can offer what is happening on top of Jupiter's dense (almost liquid?)  atmosphere.  "Goodbye Waves"  were once majestic sea ice just about vanished by melting,  leaving a trail of salts, biomass and fresh water not readily mixing with Arctic sea water,  but carried by sea currents giving the stylish twists and turns only found where there is an interface exposing the physics of two differing layers not readily intermixing.  2020 sea ice melt season will be great and perhaps will offer other planetary looks,  spectacular but too much of it is pretty bad from always pretty planet Earth.  WD June 15 2020

Laptev Sea melt madness, Goodbye Waves have no time to be artistic

~ Most dramatic record pace melting on Russian side of Pole
~Visual record shows particular "Goodbye Waves"


NASA EOSDIS July 12 to 17,  Laptev sea ice retreats at stunning speeds,  mostly by melting, as exemplified by Goodbye Waves,  not having a chance to twirl and be creatively beautiful.    Never noticed this before on such a wide scale.

East Siberian sea during the same time period,  thawing is just as frenetic,  the G. Waves  are likely from much thicker sea ice pans,  so the twisting around or final act of sea ice can be seen.   We can indirectly surmise what kind of ice it was by the last moments of its existence or life,  a pan of sea ice includes a world of beings all dependent of it.  WD July 17, 2020

Minima time rapid melting

~When most September 15's are Minima time,  sea ice in 2018 is still rapidly vanishing

NASA EOSDIS September 8-14-15 loop. 79 NORTH 180 West
Great melting has occurred when most times it should be slowed to a stop, indicating warm sea water and air effects with no possible appreciable compaction. 8 to 14 show simply melting with “goodbye waves” galore, individual packs last stand, while 14-15 comparison has differing goodby waves,
meaning different packs on their way to water. There is no doubt about strong melting very late in season.

    It is not impossible to conceive that "goodbye waves"  may be mistaken as ice packs,  as on passive microwave detectors.
   September 14 to 15 wildly different goodbye waves (left) indicate strong melting in the final phase change of differing ice packs.  Note the clouds obstructing a better view (right). 

There has been a major Arctic Ocean climate circulation change ever since
the great melt of 2012, whereas a new thinner sea ice based weather has been
firmly established. While during summer this regime is characterized by the
presence of long lasting cloud coverage favoring the presence of hovering
lingering cyclones, effectively slowing down summer time melting, this very thin ice regime
also favors more clouds during autumn and winter, whilst less melting
during summer was established,  reduced accretion during the other seasons took hold.
The net resulting effect is a slow but gradual thinning of sea ice, which
culminates to now, the minima season delayed.

Wrangel bridge waves away: Goodbye!

    Once sea ice melts to Goodbye Waves (slush), it doesn't take very long before these waves vanish to darkness.  Here we have, very late in the season,  prodigious melting not stopping,  Goodbye waves are like the steam after water boils, prominent but fleeting,  from common white to dying artistically,  in 4 days a great deal of sea ice vanished,  and the steam keeps burgeoning.

Atlantic Front retreating, likely because no substantial replenishment

~  And Goodbye Waves Palooza everywhere signifying great melting


   If the  Trans Polar Stream has less ice,  it also means less momentum and continuity pushing sea ice towards the Atlantic,  this is what we are observing with JAXA August 27 through to 30 above.  Hence a retreat throughout the Atlantic Front and even if not seen with HRPT photos,  a lot of Goodbye Waves signifying  rapid melting.  It is a reverse flow mirage which has something to do in part with the broken off flow momentum pushing dense sea ice outwards and Cyclone Centre pushing winds Eastward.

   Its a mess on the other side of the pack,  with Goodbye Waves galore,  the ex-Wrangel Ice bridge is rather a modern Art collection of rapidly disappearing sea ice. WD August 31,2016

Goodbye waves lack of geometric continuity, drastically different than melting Fram Strait sea ice

    Goodbye Waves,  not showing on JAXA at all, congrats to AMSR2 people having fantastic banzai uber precision,  have shown remarkable geometric contortions in Fram Strait,  all while not readily being identifiable from one day to the next.    Point your mouse cursor on small ice pans and note their lack of motion very unlike the Gwaves, fascinating.  WDAugust 23,2016

Plenty of melting not that it shows numerically

Franz Josef Land has near 0 C temperatures, but with sst's +2 C
Goodbye Waves a plenty,  and some opposite Transpolar Stream action effectively returning the loose pack towards the North Atlantic on its Eastern sector:  


JAXA chart  keeps on showing expansion of sea ice,  which is exactly following the 15% rule.  
There is likely no freezing,  mainly moving loose sea ice in contrary direction of the Transpolar Stream:


Looking carefully,  even with colder sea water and air near the Pole,  there is a presence of Goodbye Waves.  But far skinnier than near Franz Josef Lands.  

  The apparent open water gap filling sea ice is nothing but pack ice having plenty of dispersing room.  Note a huge sector of denser pack ice as well moving towards Russia,  likely part of de-coiling of Canadian side sea ice.    The 15% rule is very bad in describing this event pictographically. The sea ice provenance area has more expanded open water,  this does not show at all on JAXA chart,  because there is a great deal of shattering,  sea ice moving one way,  transpolar current moving the other,  plenty of stress, movement and collisions, but what the chart doesn't show is the vastness of open sea water.  Much greater than ever before near the North Pole.  WD September 11,2016

Laptev sea surface temperatures bites big time

~The entire Arctic Ocean ice pack veers clockwise from counterclockwise
~This gives a misleading slowdown in melt numbers,  it follows a usual pattern of fast-slow-slow- fast melt cycle
~North of Laptev sea Goodbye Waves abound,  a sure sign of warm seas

The ease by which sea ice pack veers or backs,  clockwise or counterclockwise by pressure system winds is a sure sign of thinness,  always intermixed with older sea ice,  but over all lesser weight of the entire pack means less momentum keeping one direction longer:
   Not long ago,  the pack turned the other way,  July 31 to August 7 JAXA loop demonstrates the presence of a steady anticyclone over the Arctic Ocean.  During the earlier switchover,  sea ice daily melts slowed down,  or appeared so,  because of scattering rather than a temperature effect.
Laptev sea was open early,  had plenty of time to pick up solar rays,  the result is rapid 7 day sea lost easily identifiable by bountiful Goodbye Waves,  these are done by sea ice just about to disappear as water.   Here 44.5 nautical miles melted in 7 days direction North,  August 1 to 7.   A speed of 6.4 nautical miles a day.   



   Also pushed North is this Laptev warm sst's very next to CMC 50% pack extents.  There is no melting slowdown possible when so.  WD August 7 2018

Individuals always melt away to darkness.


Fram Strait layered Goodbye waves join the ether of the sea.  Rapidly melting sea ice bounces about by collisions with others,  current and winds.  Goodbye waves seem curved and move more uniformly.  Like clouds a top the ocean.

  2018 has a staggering dominating melt pace; 




At the moment, the most significant difference between 2012 and 18 melt can be seen just North of
Alaska, whereas the ice flows clockwise and counterclockwise respectively, the difference being
extensive over a long period of time warmed Bering sea waters in 18 compared to 2012 Beaufort newly exposed sea surface:

We look for "Goodbye Waves" which are pre total melting of ice over a sea surface,
2012 Beaufort sea had then very few, mainly because of sea ice drift movement
dominating an apparent melting, while same date 2018:
Multiple Goodbye Waves signify rapid melting is occurring very likely from much warmed sea surface WD July 24 2018

Sea ice moved away from latest major Low pressure Centre


Latest  880 mb Cyclone was right over Laptev sea yesterday.  This is not a see through cyclone,  rather moderate to strong, we can only see its after effects once passed.  For better understanding of over sea ice floes interactions we must look at just prior sea ice movements.   
East of Franz Joseph Lands,  Sea Ice was mainly moving South.


    Notice near Ostrov Komsomolets likely Southwards moving ice but melting,  leaving a stable but badly shattered ice front with Goodbye Waves.
   In the wake of passage of new 980 mb cyclone centre, East of Ostrov Komsomolets reversal of flow direction , note the reduction in Goodbye Waves numbers and Northwards sea ice displacement.   August 15 winds are blowing  Southeastwards,  the main body of ice did not move in that direction,  but rather away from Low pressure centre. wdAugust15,2016

Dispersion of very melted broken up sea ice makes the 15% rule obsolete

     Russian sector of the North Pole had clearly a net expansion of extent,  but not because it was freezing,  much rather from the poor condition of extremely thinned breaking up sea ice.   All while there was melting.  So it is very difficult to judge either how fast the melting is unless dispersion is taken into account.    The other way to judge is by Goodbye Waves:

    Dispersing more rapidly Goodbye Waves are a sign of melting amongst winds and currents.   Judging melting correctly would be to factor in,  not exclude by an arbitrary rule,  every parcel of open water and sea ice as accurately as possible.   WD Sep 9,2016

Atlantic Front: substantial evidence of massive melting, 'goodbye' waves a plenty


All along the North Atlantic sea ice front,  about 1200 Kilometres long,  there are numerous new 'Goodbye' waves,  sure evidence of recent massive melting.  From Fram Strait,  to North of Spitsbergen to beyond Franz Josef lands,  as seen here in our roving NASA EOSDIS shots.  Although the newish extended sea ice front line position has recently expanded and appears  more or less stable, that is an illusion,  the sea ice melts just as fast as it touches warmer water.  The end result is a great loss of sea ice.  Assume Southwards sea ice movement a modest fluid 2 kilometres an hour ,  about 48 kilometres a day melt along apparently a steady front,  potentially 60,000 km2 a day loss is possible, without actual remote sensing detection.

Tale of 2 sides of the North Pole, one with fresh snow cover, the other a summer cloudy day

 A 2018 special feature wide open water where no human has ever seen before,   was covered up by
snow  ,  as if it never happened.  But it is still there,  under very thin or snow covered sea.

       There is a stalemate in the Atlantic front,  very warm North Atlantic waters keep any progression of sea ice at bay.

   September 14 15,  15 is the one with withe tip at top most end of sea ice,  the North Atlantic front is still heading towards the Pole.  There is a distinct possibility that AMSR2 confuse "Goodbye Waves" with rock hard sea ice.  daily scattered/compressed oscillation of sea ice suggests so.

    80 N 166 W NASA captures 8, 10 and 16 September,  leaves no doubt of further melting  from within,  a compacted ice pack would have less water from within.  

78 N 173 E,  proof of melting again,  with a very small bit of compaction can be determined by the slight displacement of largest pans at right,  while bigger number of goodbye waves in a mere 2 days. WD September 16 2018

Atlantic front; very rapid melting

~A look at some record pace melting. 

   EOSDIS July 11-12   2020 Just North of Spitzbergen,  look and place mouse pointer on the "Goodbye Wave Peninsula"  lower centre right of animation,  the basic nature of Goodbye Waves stages of melting demonstrate huge pans of sea ice, 1 km wide vanishing in a day.  The winds on July 12 were light in the photo sector.  The sea current is somewhat rapid,  approximately 1 km and hour towards the NW.  A weak cloud cover is also key in more rapid thawing at this time of summer.   The same speedy liquifying can't be repeated,  slowed and  hampered by denser pack ice (colder sea surface ) and denser clouds near Franz Jozef Islands.  WD July 12, 2020
