Not really, it is surrounded by a huge melt pond.

The snow is now beginning to melt around the other webcam

I think what happens next is that the melt water drains away off the edge of
the ice flow into a lead. I wonder if I am right.

Cheers, Alastair.

The melt pond was even deeper on Saturday:

Presumably the draining of the melt ponds explains the current kink in this

I doubt it, as I think it's unlikely that all the melt-ponds would drain
on the same day. However, it's possible that the satellite
ice-concentrations may read low if there's extensive puddling.
Similarly, in winter, areas of flat, unbroken, possibly snow-free ice
show up as not being 100% cover.

And here's a bit more info on that melt-pond.
