Isn't the current hugging the right side a result of the Coriolis effect?

Hans Island is mostly steep-sided limestone or dolomite, so it likely erodes mostly from the sides.  Ice floes will basically cause below water line erosion, while freeze-thaw action, chemical weathering and surface runoff will affect the subaerial surface.  Per the internet chemical weathering of maybe "one-twentieth of a centimeter every 100 years" could be expected, but this would be in a more temperate climate, so I'll guess a 0.25 to 0.5 cm of loss this past 2,000 years from chemical weathering.

I'm really just guessing, but 500 good bumps or scrapes per year, so in 2,000 years, what, on the order of a centimeter or two?

In this Sentinel shot, there is still ice on the shores of Hans. I wonder if this ice is somehow compressed and acts as a bumper?

That's a possibility i never considered. Added to my variables list.

well worth a peek back to 2009 on Worldview .. forward thru the next week .. a mega-floe arrives at the entrance .. b.c.

B.C., do you mean the fast ice monster in the north of Greenland? It barely moved west though.

Surface current has stopped again.

There are northwards winds atm.

Slightly ot, interesting animations of arctic tides, though i think they've developed, showing the surge out of Nares into Lincoln. http://fvcom.smast.umassd.edu/2014/01/27/4-research-tidal-simulation/

m2_ar in Lincoln looking pretty close to the shape of yesterday's polynya (though it matches the bathy as well)

I'm positive the polynya in Lincoln is caused by tides, Uniquorn. It forms when there is no southwards surface current in Nares.

yes, tend to agree, but at the moment it's caused by melt rather than an arch. So maybe mixing caused by tides.

Yes, agreed. There is a lot of melting going on in all of the Strait. Warm water might get pushed south.

Edit: Add SST from Windy (ECMWF).

DMI-crop animation.

I think the polynya has closed at the moment - or is this dust in the last frame?

However, the whole pack came down a little.

Those grounded icebergs in Kane Basin are somewhat of a mystery to me. With all the swirls and tides and standing waves going on there, one would think they can't last long.

Too sad Rammb doesn't pick them up. I would love to see how they move in tides or how they behave when a floe runs into them. I've seen them wiggling around on Sentinel, but with a daily resolution, it's hard to see what's going on.

Here are two of those icebergs.

Seems like the left one made it loose.

The time frame here is 01.08. to 11.08 without cloudy days.

Those grounded icebergs in Kane Basin

Looks like this on radar btw.

I see a wavy pattern. As if there were dune-like structures below?

That ice is a mix of glacier ice (from Humboldt Glacier) and sea ice from the north somewhere, I doubt the sea ice is from Nares, the glacier ice will survive at least half year if it gets out of Nares and into Baffin Bay before seasonal shutdown.
Have a ice day!

Thanks Oren. :)

Most floes in the basin are likely melting out - they will be pushed into the warm water sooner or later.

But as Espen said, a lot of stuff is grounded icebergs. I don't think they will melt this season.

DMI Lincoln and Kennedy crop.

Floes are entering hesitantly. Are they pushed in from the ice pack above, or is there a mellow current?

If there is a current, Alphabet Hotel called it a few days ago!

Nares Strait export may be starting again. This is yesterday vs. today.

Ice on the [other right] side of the strait, my take

going from the pole to southern greenland is about 300 the difference in tangential surface speed is 500mph+ so about 17mph/27kph per degree, the only way the ice gains speed is to spend a little time on Ellesmeres coast.

There was no DMI Kennedy/Lincoln crop for yesterday. Meh -.-

So this GIF is missing the 20th. No southwards surface current (yet) i say.

Mass tourism in the Arctic. Can you imagine the year after BOE?

Looking at Hans, it is no mystery why flows shatter when they slam up against it.

Thanks so much for sharing, Espen. Great to have this perspective for once. Not too shabby they went there after all. ;)

The wind north Nares / Lincoln is blowing northwards pretty hard at the moment and that seems to push the ice out of the channel. We will have strong winds in this direction for two days straight.

In this GIF i have increased the contrast to veil dust. I think this works well. If you like the originals better, let me know.

Now out of Nares Stræde, but just south of Smith Sund, we got the mystirous Carey Øer and in the mist like in a Von Trier setting, its amazing what you can collect from a deck on a cruise liner nowadays:

You may spend a some 15,000 USD or more for this trip, wawes are not excluded

Apparently, the floes are, driven by wind, moving north at the moment. And look, they are confined to the right side of the floating direction.

Your comments and thoughts, please.

The artifacts produced by the "panoramic" webcam when the wind gets up are most intriguing!

SST in Kane basin went down.

Is it reasonable to think that the storm there has mixed the water layers?

Another thing the storm caused is a huge polynya at the entrance. I'm stunned there are still floes in the strait.
