Viewed from space dark sea ice is toast, but may last a long time

We know the sea ice formed late in Barrow Strait,  this ice was thin at maxima in May (not like overall extent of  all sea ice),  made thinner by extra snow layer. Eventually it disappeared on July 7 2018, but for a persistent thin zone South of the Island, mainly in blackish.  The older in age first year ice has greyer shades.   These surviving sheets should eventually melt and disintegrate.  So did the blacker sheet at about July 12.

    If we compare these mechanics to the larger over all sea ice areas,  we now must look for the tell tell black shade depicting thinner sea ice. WD July 16 2018
