Thicker sea ice? Find where the snow was missing.
A very striking feature of sea ice topography at this melt season stage is the elongated Ice Bridge from Komsomolet Island Northwards:
August 2 2016 JAXA, The only unperturbed sea ice appears as an arm stretching to Russian Arctic in deep purple. This is not a surprise, over the last winter, the main dumping surfaces for North Atlantic moisture was The Canadian Greenlandic Sector, leaving The greater part of the central Russian Arctic dry:
The best Arctic snowfall pattern depiction was made in Europe, Topaz 4 , find the same ice bridge, created by winter's cold dark long night without a great snow cover. Also take a look at where most open water is, especially away from sea shores. In addition, the stubborn North of Wrangel Island sea ice panhandle can almost be depicted by this map. Areas with more open water can be traced where there was more snow, except for the Canadian Archipelago coast, a very complex ridging zone, where sea ice piles up due to Tidal action, however the sea ice there might just as well be thinner than expected, because a greater snow cover decreases accretion.WDAugust 3,2016

Sea ice to water everywhere, latest 2016 melt captures "Goodbye Waves"
By finding for "Goodbye Waves" we can confirm melting wherever they are found.
They are useful in confirming thawing in not so common places. WDAugust2,2016

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.

Back to water..... That just melted "goodbye" wave look
North of Beaufort sea has similar features to Fram Strait especially now. Ice almost completely melted gives waves, similar to cirrus clouds announcing an approaching front:
At extremes of the great Fram Strait melting zone lies the last remnants of sea ice, whose physical nature really becomes elastic, from solid to slush/rubber to water. It is a sight everywhere sea ice melts. In this frame, present Cirrus clouds may be confused with melting sea ice.
Even North of Beaufort Sea:
Its melting North of Beaufort very fast. But just before disappearing, sea ice takes the shape of waves not so dictated by being very rigid, these waves are water in transition from appearing solid white to dark liquid. Each melt region has different melt transition characteristics. Which is of course as individualistic of the geophysical features about.WDJuly31, 2016

Rapid Supply and Melt North of Mackenzie Delta Inuvialuit nunangani
At present, the Beaufort Gyre current is very healthy with rapid continuous ice floes for the melt slaughter, again to the point where we can't readily easily identify any ice pan which disintegrates in shape and size in a matter of days. Note in particular the apparent lack of day to day extent shrinking. JAXA and other Grids may show very little melt progress but there is in fact huge ongoing melting.
Melting occurs while the supply lasts:
Further North of Northeast, the Central Arctic Basin has not an infinite supply of sea ice, although it may appear as such. Note CAB sea ice pack density literally going smaller day by day, again extent numbers wont really explain this rapid melting until there is less ice than the required 15% threshold . Archipelago Islands of course provide no such resupply, with the current flowing of sea ice away from them, these Islands provide "land shadows" , these give a net but small extent drop, however this is how the NW channels open suddenly, there is much more room for sea ice to move about.

Water temperature +.9 C at 77.8N 157.1W last report of Mass Buoy 2015j
Near 80 N water temperatures still with quite a lot of ice cover, was measured a very warm if not hot +.91 C July 22, by Mass Buoy 2015J last report. The arrow points to very near its location. Well further away from wide open water. This temperature means bye bye sea ice, and mass buoy 2015J should turn soon into a boat at any moment. What surprises is how dense the ice was with so warm a water under. The bottom thermistors read -1 C which may be more accurate, however throughout the winter the Buoy appears to have recorded very good water temps.Mass Buoy 2015f, well further North 83.49 North, has -1.4 C water.
There are 2 more locations with 1 degree sst much nearer the Pole, likely retrieved from remote sensing. Those in circles are in doubt, not necessarily incorrect, although the one North of Greenland +28C may be judged incorrect. Note Chukchi sea +10 C North of Novaya Zemlya +6 C, incredibly warm waters.

See through Cyclone; not so much clouds
This very artistic, elegant, cyclone North of East Siberian sea is not very cloudy. Adds to the complexity of already mixed up ice, along with with different weather features. wdJuly27,2016

Very little wind significant change North of New Siberian Islands
Again the larger question is how already badly broken up 2016 sea ice is reacting to Cyclonic winds? Let's see what merely an approaching Cyclone did North of Siberia after July 19:
There are at least 2 concurring major contributors to icescape dilution: one is critical temperature of sea ice core nearing multiple possible melting points, 2 is the approaching Cyclone covered in the previous article. Spreading and shattering ice around and very likely accelerating melting. Let's see the net effect with 2 clearest pictures:
Devastation with very little wind, water to ice extent ratios have increased substantially, many ice pans have shattered and are difficult to recognize. This is a small example of what a truly powerful Cyclone can do. WD July 27,2016
