Is this the head of a giant snowman (yellow scarf, green mouth, dark blue eyes), as seen through a window with panes (black lines)?

Sea Ice Transport 20.03.2017: a vast tongue of sea ice is passing well past the Franz Joseph Land to the Barentz Sea and weak sea ice around Svalbard today: https://worldview.earthdata.nasa.gov/?p=arctic&l=MODIS_Aqua_CorrectedReflectance_TrueColor,MODIS_Terra_CorrectedReflectance_TrueColor,Coastlines,Reference_Labels(hidden),Reference_Features(hidden)&t=2017-03-20&z=3&v=638544.5625044382,-490825.29911611415,1687120.5625044382,169654.70088388585
From the size and shape of the floes, I'd bet that those are some of the die-hard MYI boulders which made it through last summer in the Northern Laptev. So long...

Hi All
This is my first blog on your wonderful site which I have been watching for nearly a year.
Today NASA announced that Greeland and Antarctic are losing 400 gigatons of ice / year. I have just calculated this as giving 2.38 mm / year height increase. Water thermal expansion + glacial and other surface ice would be in addition to this (also aquafier surface pumping). Does this seem a bit high ?

Welcome, Jontenoy. Your profile has been released now, so you can post freely.  I see that you've asked your question in the SLR thread as well. This one is for Arctic images.

That image is addictive.  "Stop," I say, "Stop!  Turn it off.  Unplug it if you have to.  Stop the machine - it has gone too far!  We've lost too much sea ice already."  :'(

The icepacman of the Fram Strait has been active today: 350 km x 325 km chunk of sea ice is now leaving the Central Arctic today (24th March 2017) with large separation gap forming. I doubt that any bigger section of the Arctic Ocean ice cap could get through the gap, but you never know what comes next behind the bend (or more correctly what leaves from behind the bend [of Greenland])... https://worldview.earthdata.nasa.gov/?p=arctic&l=MODIS_Aqua_CorrectedReflectance_TrueColor,MODIS_Terra_CorrectedReflectance_TrueColor,Coastlines,Reference_Labels(hidden),Reference_Features(hidden)&t=2017-03-24&z=3&v=87993.52285053895,-1196593.2128281824,1136569.522850539,-536113.2128281824

It's spring on the NE coast of Newfoundland, which means the polar bears that follow the whelping herds of harp and hood seals out on the pack ice are on the move. Some come ashore and often wander around remote communities, at great peril to local residents----and, sometimes, sadly, to themselves. This one was spotted in Wesleyville  (latitude N49.15) on March 29, which is near the southernmost limit of their range. The RCMP and wildlife officials have issued warnings and are monitoring.

Personally prefer the second photo, but the first has more chance of going viral.


Nice to see a bear that doesn't appear emaciated.

I came down with a cold just after landing last week, then had to nurse my sweetheart who for some reason blames me for bringing the plague up to Inuit territory like I'm a genocidal European explorer.

But now that we're better, I have time to share a few photos. I'll space them out this week.

Today's photo, a cool feature I saw on approach to Iqaluit: rings of ridged ice around the shores of Frobisher Bay and its islands.

Here's a close-up view of the ringed ice I photographed from the sky. This is on the bay between the Tundra Valley and Apex neighbourhoods of Iqaluit.

When you're in it, you can't see the pattern. It's about 200m of rough ice (at a guess; I could be off by a fair bit) out to the smooth ice in the bay; there's a clear phase shift at about 150m from shore where suddenly you only get a few big lumps and mostly smooth ice. I can guess at mechanisms for that phase shift but I don't know exactly -- my main guess is that it's where the low tide shoreline is.

Where I took this picture is a sand beach, so the rough ice has a lot of sand embedded: it formed when the water froze at low tide, then got lifted up (the tide is very strong -- about 8m here). Now that it's April, we see the ice around the dark sand melting out very fast.

The sun is incredibly strong: air temperature was -15 C but I was in a small sweater, snow on my boots was melting almost immediately, and when I headed back, the snow had warmed enough that it wasn't sticking to the wax on my skis. Also I had a good sunburn.

Ha! I just came onto this thread in order to post that image!

One doesn't see a sight like that very often in South West England these days. (It's been a while since the LGM.)

That's an amazing sight. Trying to judge the size of a more or less featureless chunk of out-of-context white can be tricky, but there's got to be, what, 60 meters of freeboard on that thing?

From that article:

It's already been a busy season in iceberg alley, with hundreds of icebergs reported in the Atlantic - many more than usual for this time of year in the coastal regions.

Indeed...

This is not far from me. Beautiful, yes, but they keep the water and the air so cold and can ruin the summer. Ice also can play havoc with fishing gear. Tourists love it because they don't have to live here. Those of us who have grown up with ice are praying for a solid month of sou-westerlies to take the bergs and the pack well out to sea, and good riddance! :)

FYI

Latitude of Ferryland is 47° 2' N.

So, more southerly than Paris, France.

This is Derrick Bath's vessel, Polar Adventure, battling sea ice at Twillingate, a couple hundred km north of that spectacular berg in Ferryland. Sea ice is a  a major problem for Newfoundland fishermen, coming as it does during lobster and crab season.

A good reminder of how the North Atlantic Drift keeps me warm in England at 52 N.
Just once in the extraordinary winter of  62-63 there were ice floes under Brighton pier on the South Coast of England. But not 46 m high.

Still, there are worse things in this world than a berg made of ice. Imagine waking up one morning, and finding one of these right in the middle of your view...

Oo er!

I noticed this was from "Wikimedia"; so maybe it's a generic pic? Published 6 April.



Around 450 icebergs — defined as hunks of ice covering at least 5,382 square feet and between 98-164 feet in thickness — are lurking off the coast of Newfoundland and Labrador, well above the average of 80 usually found for this time of year. The swarm appeared suddenly, too. Just last week, there were only 37 icebergs in the region.

The highest concentration of rogue ice is off the southeast tip of Newfoundland.

and

true, while the base under water is most probably wider similar to tree roots, else it's getting ready to topple :-)

If that was sea ice, rather than a chunk of calved glacier, AND ...

if the Lebedev formula for ice growth still had some skill over such an extreme range, then ...

if we said it had an average thickness of ~ 400 metres, then ...

the number of Freezing Degree Days necessary would be approximately 50 million.


That would just require a temperature of -50 degrees Celsius, for about 27 or 28 centuries.

Even I might be prepared to accept a small wager that such a prolonged cool snap is not on the immediate horizon.

Hi Susan. The metadata indicates it was taken August 14, 2011, near St. Anthony, which is near the NE end of Newfoundland's Northern Peninsula, not far from the SE tip of Labrador on the mainland.
