Military sonar technology causes beachings
Submarines have been using low and mid-frequency active sonar technology, a deafening soundwave that is dangerous even 300 miles from it's source. Some mid-frequency sonar systems can put out over 235 decibals, which is about as loud as a rocket launch.
Animals for hundreds of miles literally jump out of the ocean to try to avoid the sound. The damaging effects vary, bet are akin to decompression sickness causing internal bleeding and bursting organs including lungs and eardrums. When beached dolphins are reported this sonar technology is rarely mentioned in the news, although the link has been demonstrated.

How much of an iceberg sticks out of the water?
An iceberg is a mass of ice that has detached from an ice sheet and is floating in the ocean. Icebergs pose an extremely dangerous situation for water vessels because only about 1/8 of the iceberg mass projects above the surface of the water.
