Vessel Measures Record Ocean Swells

By Markus Becker

A British research team has observed some of the biggest sea swells ever measured. A whole series of giant waves hammered into their ship that were so big, according to computer models used to set safety standards for ships and oil rigs, they shouldn't even exist.

When the RRS Discovery set out to sea, the crew was expecting stormy weather. Meteorologists had predicted a violent storm, and the scientists -- a team from Britain's National Oceanography Center -- wanted to observe it from up close. What they ended up experiencing went far beyond anything they could have imagined -- and could have cost them their lives.

Near the island of Rockall, 250 kilometers (155 miles) west of Scotland, enormous waves came racing toward the vessel. When they checked their measuring instruments later, the scientists discovered that the tallest of these monster waves had hit nearly 30 meters (98 feet) at wind force 9. And it didn't come alone. "We were shaken up these waves for 12 hours," said Naomi Holliday, the leader of the expedition. Entire sets of giant waves hammered the ship.
