Cross Section Through The NSIDC Ice Maps

This is what troubles me about the NSIDC ice age maps. The image above is a sample cross section through the ice. The multi-year ice (green) disappeared after July, but left the much more vulnerable first year ice (pink) intact.

In order for this to happen, warm water would have to flow under the ice for a thousand km without equilibrating, and then selectively melt the solid, hard to melt multi-year ice – while leaving the rotten first year ice intact.

There are quite a few problems with that theory. What am I missing?

I sent off a query to Julienne about this earlier this morning.
