The "Molar Berg" (#iceberg #D28) is getting together with the Stancomb-Wills Glacier Tongue for Christmas. No social distancing being practiced here, but no damage evident on either side so far.

That could happen, but icebergs calved from the Filchner Ice Shelf, where A23A came from, generally have keels deeper than 400 m, where are ones from the Amery Ice Shelf, where D28 came from, generally have keel depths around 300 m or shallower.

If we know the freeboard can we estimate the keel depth? Might try to find some satellite overpasses to get the freeboard, assuming we ever get clear enough skies!

That's how keel depths are generally estimated. A correction should be made for the firn depth, but fortunately this should not be too large given the low accumulation rates around most of East Antarctica.
