Update: since Ronne Ice Shelf, from which A-76 separated, has ice thickness of about 150 meters [1], if A-76 has the same level above the water as the Ice shelf, about the same surface underwater (which likely is not the case, but good enough for this rough estimate), then 9/10 of the whole iceberg volume is underwater, meaning that the depth underwater is about 1.3 km. Though the area of the iceberg usually increases underwater and the depth in that place is just about 500m[2], so likely it is something like that.
