sentinel is great for this, this image is of a piece of ice grounded in shallow water off the east siberian coast. Landfast ice between the grounded piece and the coast seen near the bottom of the image has now broken away but the grounded piece is still stuck.

Nice!!
For comparison, this is what Worldview shows in the same location and day.
With the new tool, some discussion whether that is "garbage ice" or slush or not will be more easily solved (or will it create some more). https://go.nasa.gov/2uyO8bY

Time for a little game. Identify this ship in Hudson Strait at noon today! It was sailing eastwards, dodging some smallish floes.

Between the GPS information embedded in the jpg and the public ship logs it should be possible to work it out exactly. I don't actually know the answer.

It was a beautiful day to fly YOW-YFB: starting about at the tree line in Quebec, there were no clouds. I'll have to go through my collection and pick out some nice ones of e.g. the glacial striations on the ground (caused by the retreat of the ice sheets), and the sea which still has wisps of ice in it. And I caught the final approach on video.

An iPhone looking out a passenger window of a 737 isn't the best photography platform, but it's better than you might expect! The main difficulty is when it decides to focus on an ice crystal instead of the background.

Summer has arrived to melt away the hardest iron shield of the Arctic Ice at the core of the ocean. Many other areas of the Arctic Ocean shows rapidly fracturing ice cover, or readily pulverized ice - even near the North Pole (good snapshots to be seen in many areas of the ocean in clear skies):

Here's a candidate for longest observed contrail.
It extends across the Beaufort Sea from a point north (approximately) of Tuktoyaktuk (NU Canada), to a point north (approximately) of Prudhoe Bay (AK USA).

Waves lapping the shore at Barrow Alaska. Wave erosion is bound to increase as larger areas of open water appear. This in addition to melting "perma"frost may cause rapid coastal erosion.

An entire weekend of strong winds straight up Frobisher Bay and all I got was these lousy little floes.

There's a lot more off in the distance, just not coming up into Koojessee Inlet.

Those ice floes turned out to be bigger than they first seemed -- as I should have expected, since most of the volume is under the waterline. Here's the dragon of Koojessee Inlet:

A beautiful coat of seal and caribou with beads would be more authentic -- not to mention the fox-lined hood with a baby inside. But ice floes in Iqaluit are like squirrels in Montreal: they bring out the foreigners (like me) to take photos.

The summer temperature here is very strange to me. What the thermometer says is almost irrelevant. What really matters is the sun and wind.

I can sit outside by 4 degrees in shorts & t-shirt if it's sunny with calm winds. Conversely, Monday night in my "late fall" clothes (by Montreal standards), I was huddling next to the campfire and shivering despite it being 10 degrees: it was somewhat windy!

In summer, seems wind direction matters a lot too: wind coming from the southeast is cold, wind coming from the northwest is warm. Southeast is water & ice; northwest is land (with a bit of snow left in the shady spots). In winter it's not so different given that it's snow and ice in all directions.

ice floes are prone to the same rules like any other swimming ice including huge icebergs, hence this is the norm, just often forgotten.

Interesting. That'll fluff up the Ionosphere and increase its insulation capacity.

Active Region 2665 produced a long-duration solar flare measuring M2.4 at its peak time on July 14, 2017. Today's event lasted for more than 2 hours; it started at 01:07, peaked at 02:09 and ended at 03:24 UTC. The eruption produced a coronal mass ejection (CME) with an Earth-directed component. This region is now moving away from the center of the Earth-facing Sun but could still produce moderate to strong eruptions in the days ahead.

The eruption was associated with a Type IV radio emission. Type IV emissions occur in association with major eruptions on the Sun and are typically associated with strong coronal mass ejections and solar radiation storms.

This CME is expected to reach Earth late Sunday, July 16 or early Monday, July 17.




Additionally, a 10cm Radio Burst lasting 44 minutes with peak flux of 130 sfu was associated with the event. A 10cm radio burst indicates that the electromagnetic burst associated with a solar flare at the 10cm wavelength was double or greater than the initial 10cm radio background. This can be indicative of significant radio noise in association with a solar flare. This noise is generally short-lived but can cause interference for sensitive receivers including radar, GPS, and satellite communications.

The greater than 10 MeV proton flux at geosynchronous orbit exceeded the S1 - Minor solar radiation storm threshold at 09:00 UTC.

The model below shows CME impact expected on July 16:

Region 2665 (beta) is now moving away from the center of the Earth-facing Sun, but is still potent enough to produce moderate to strong eruptions in the days ahead.

CCGS Amundsen showed up this weekend (I only finally got the picture off my phone).

At the same time, two empty cargo ships showed up. I assume Amundsen escorted them.

As a resident, what do you suppose two empty cargo ships are doing? These must be about the first ships of the season- and I should have thought that they would be fully laden. Or does all the freight come by Amazon now? ;)

They looked empty, but one it turns out is a tanker, not a container ship. The other I must have misunderstood what I was seeing, because it started unloading yesterday (why it was out there several days without unloading seems to have confused more than one person). That or the ship I saw was a second tanker, left, and was replaced by the first container ship of the season.

What timing! Right after my previous comment, a container ship just steamed off. It's not the "empty" ship I'd seen -- for one, there's big cranes on it; for another, its full of containers.

It's a bit hard to observe from where I am because all but one of the ships is hidden behind an island at the entrance to the inlet. There's no port here. At high tide a barge goes out and they haul cargo onto it.

Was ist probably the Emmagracht (aka Mitiq)?

The Mitiq arrived Wednesday apparently; if it's the one that steamed away it's ahead of schedule. The ships I saw last weekend must have been the two tankers. The paper also says it's a different icebreaker than I'd thought, unless there are two icebreakers here right now.

From the wording of the facebook message I would assume, that there were 2 icebreakers there: One that escorted the Mitiq, and one that escorts the two tankers.

If you click on the position-link on the sailwx-webpage I linked before, you will get a map and a list where the other ships in the area are also shown.
According to that, there are two ice-breakers there:
The CCGS Terry Fox and the CCGS Henry Larsen.

Hopefully I'll be able to take a photo tonight or tomorrow morning. There are two cargo ships and a tanker visible from town, whereas sailwx only shows one.

A bit of ice has floated in as well owing to the SE winds all week long. Might be a pretty sight!

One ship came in during our hike on Saturday, and another left just before sunset. The barges have been unloading madly.

This panorama shows the ship coming in on the left (Southeast), the suburb of Apex on the right (Northwest), the neighbourhoods of Tundra Ridge and Tundra Valley in the middle, and the fuel tanks that store our precious reserve of deadly fossil fuels. No barges yet visible -- they must have been about to head out with the tide coming in.

The wind was been from the Southeast for days, so the ice moved in. On the far right you can see how big those chunks of ice really are, though they barely float above the water.

You can see the road to Apex on the far right, then a small path down to the water. That was our path. We started hiking a bit before 2pm, when the tide was at 2.6m. About halfway across the inlet I called on the rest of the group to stop taking so many pictures of the growlers, because the tide moves fast. They though I was being a doddering old man but agreed to placate me. When we finally got across after just an hour of walking, the tide was at 4.5m. We had lunch, headed up a small hill, looked back, and that's when my companions realized that the tide is not something you fuck with around here. At the new moon it rises faster than 2 meters per hour!

For the earlier discussion: the Mitiq left on the 22nd but not to Pangnirtung -- the schedule flipped two destinations, delaying the Pang trip by five days on account of ice.

Apparently both the Zélada (which has my stuff) and the Qamutik showed up on the 22nd. I don't know which is which in the picture.

A qamutik is the sled that sled dogs pull (though typically these days it'll be a snowmachine instead) -- a common sight around town, most houses have one somewhere on the property. It's quite the fitting name for a cargo ship. Certainly better than the Mitiq, since I'm not sure I want "a large and fast sea duck" carrying my valuable goods.

i'm curious how much green lawns we gonna see there in a few years, perhaps i'm wrong but it looks a bit like things are getting greener than they were a few years ago. at least i always felt pity for people living in gray and brown sand and gravel and now it's getting almost pretty, relatively though :D

sure, didn't mean country-side, meant within city limits.

except the mosquitos i love tundra as well, since my first wife from russia i had the pleasure to grasp some of it's beauty, even though on the other side of the arctic ocean :-) one of my daughters and 2 grand-kids are currently living in Dudinka (Дудинка) at the Yenisei river (Река енисей) doing some biological research.

Ah, I agree.

I look out onto the inlet, which is beautiful; and tundra in the distance, which is beautiful, and the city dump, which is not. Closer in I look out onto a bunch of shacks, decrepit boats (some of which double as shacks) and rusting containers (idem), dusty roads and walkways, only half of them paved. The tundra is too fragile to do well in town.

Yesterday a friend took us by zodiac out onto the inlet despite rough seas (30+ km/h winds all day). We got a close look at that young sea ice. We tried to go through a channel between some islands, but it was blocked off by "thick first-year ice" as the Canadian Ice Service puts it -- albeit at a much smaller scale than they usually look for. The mostly southeast winds we've had all of July (as opposed to the predominant northwest winds) have kept the town cool, prevented the mosquitoes from breeding, and blown a lot of ice up.

There's no more ice that we can see in Frobisher Bay -- it looks like it's all been blown on shore (except one small chunk we saw floating on its side; presumably it had been on shore, melted down, then floated off with the tide). The ice maps show that this holds most of the way to the mouth of the bay.

numerobis,
What is the height (above the water) of those pieces of floating ice?  (What is the freeboard?)
Arctic ice is healthy for children and other living things.

You can see the zodiac I'm in for scale; the ice is 50cm-1m above the water line.

They aren't floating though -- small boats stay well clear of anything that's floating! You can walk across that spot except at high tide.

Thanks; my best guess was 'most of a meter', but I wondered if my sense of perspective was off, because 3/4 meter freeboard would mean 6.75 meters below (or the mass equivalent spread out), and there isn't much 7+ m thick FYI!  Your saying that ice is all grounded makes the scene make sense to me.

You can actually see the melt line on this ice which became exposed as the tide went out and the ice grounded.
