Were extreme waves in the Rockall Trough the largest ever recorded?
In February 2000 those onboard a British oceanographic research vessel near Rockall, west of Scotland experienced the largest waves ever recorded by scientific instruments in the open ocean. Under severe gale force conditions with wind speeds averaging 21 ms?1 a shipborne wave recorder measured indi...
