I have compared Sentinel images of the Lincoln Sea dated 01-22 and 01-24. All distance moved are over this two day period.
A large floe in the middle of Lincoln Sea went about 7 km. A large floe almost to Nares Strait (on 01-24) went about 20 km. Floes closer to or in Nares went further (45 km or more).
Looking at ice floes in the upper left part of the images that, although with identifiable boundaries, are in close contact with their pre-separated neighbors, and ice that looks to be part of the Arctic ice sheet (no clear floe boundaries, at the top left of the image) I see ice moving 9 to 12 km toward Nares Strait. (Some cracks open wider, and others close up.)
From this data, I conclude that not only is ice breaking off the Arctic ice sheet in the Lincoln Sea and heading for the Nares Strait, but that a section of the Arctic ice sheet is also moving toward the Lincoln Sea.
Looking at ice in the upper center and upper right of these Sentinel images, the ice is moving very little; in some places it is moving a tiny bit toward Fram Strait.
Comparing NOAA AVHRR images (2015-01-19 13:30 and 2015-01-23 12:46 - among the best recent images available) that show a much larger part of the Arctic (over 400 km north of Nares Strait), note the major crack that goes from the Ellesmere coast near Nares Straight almost straight up the images. I can identify marks on the ice to the left of this major crack (e.g., one about 270 km from Nares) that don’t move between these two images, whereas marks to the right of this crack (e.g., one also about 270 km from Nares) show about 7 km movement toward Nares. (A mark about 400 km north of Nares moved about 10 km, but as it is to the right of a Fram-related crack, its motion is toward a point on Greenland some 200 km east of Nares.) This data supports my conclusion (above) that a section of the Arctic ice sheet is moving toward Lincoln Sea, although this movement may be more related to what I have called Fram Strait related cracking and that the movement toward Nares may be coincidental.
With my geological education, I call a crack that has transverse movement (like the San Andres fault) a fault. Natural ice is a mineral, so the ice sheet and floes, etc. are monomineralic rocks. I consider the major cracks identified in the previous paragraph which have transverse movement to be faults.
