A violent storm brewed in Alaska sent waves 8,000 miles to break up a massive iceberg in Antarctica. To do this damage, the waves had to travel the entire length of the Pacific Ocean, northern hemisphere to southern hemisphere.
Scientists had been studying the iceberg for other reasons, and had sensitive instruments in place that could detect all of the details of the icebergs final shuddering breakup.
The sheer distance traveled by the storm waves stunned scientists, who reported "our jaws dropped." It's interesting to learn that even experienced experts can be stunned and surprised by the power of the ocean.
