It said to be 42 m 138 ft high above water, given a ratio of 1/5 above water, that would make it 210 m total or approx 689 ft tall and I'd be anchor 560 ft on the sea floor, those are mind boggling figures
When they figure above and below, they base that on the volume of the berg, and it can vary considerably. About 90% of the volume will be below water, but that doesn't mean 90% of its total height. That volume can be spread over a wide, shallow area, or it can be narrower and go deeper.
I wonder if divers will go below to take a look.
