CM, it is a sad reality of Internet forums that those who are intelligent enough to employ self restraint post much less often than others who are not as self aware.
Be that as it may, I encourage you to post more often, and be aware you are easy to understand and quite coherent.
To your specific point, it seems to me the huge melt pond area is on the sea ice in the fjord, rather than on the ice shelf itself. I note that another section of sea ice adjacent to the ice shelf has extensive (but smaller) melt ponding, right of the center. I have no specific explanation for the interesting phenomenon.
