The sun was at a wonderful early morning angle as we approached the edge. The iceberg sticks up out of the water 75 m (250 ft). That's about a 25 story building. The general rule for icebergs is that one tenth of it sticks up out of the water because the density of ice is 0.9 g/cm^3. However, the upper ~ 40 meters of this iceberg is just compacted snow (less dense than ice) so we don't know exactly how deep the berg is.
