Got this in my email:
EVER SEE AN ICEBERG FROM TOP TO BOTTOM?
This is awesome! This came from a Rig Manager in St. Johns, Newfoundland. They actually have to divert the path of these things away from the rig by towing them with ships!
Anyway, in this particular case the water was calm & the sun was almost
directly overhead so that the diver was able to get into the water and
click this picture. Clear water huh? They estimated the weight at 300,000,000
tons.
