A new row of candidates in the ESS further south.

S1 close up of the lower candidate in the above post. The small island in blue, something just visible in the possible shoal area (marked, top left).  cffr

Another candidate (seen before) further east of NSI. 2 are visible on these images. ctr

Blum just told me about this thread, so I'll duplicate my message from the newbie thread here.

Last year we had a small discussion here about grounding icebergs in the Arctic ocean, because I thought that one got stuck on the seafloor in the ESS.

This year I'm seeing that bottom-fast ice again (bottom right corner), and it's doing something weird. It seems to be blocking a whole lot of ice inbetween it, and another bigger piece of fast ice.

I noticed it yesterday already, but waited another day to see if that very little piece of ice against that little round piece of BFI would be able to hold that entire icebridge in place. And it seems it was. Quite amazing...  :o

Ocean depth there is around 15 meter according to this GMRT map tool, and I haven't found prove yet that this ice is stuck on an underwater island. Although I do believe that's what it is that this fast ice is stuck to. Maybe someone should take a dive there to update the bathymetry charts?

Anyway...
What do you think is happening here?

It's in the moose head in the ESS. Worldview.
Is there an easy way to copy those Lat/Lon numbers from Worldview?
The little one is 73°14.000'N, 151°04.000'E

Please see post#34. Thanks for confirming their reappearance this year. There are some suggestions for causes upthread also.

3 or 4 large areas of anchored ice in the Laptev.
