Taking the surprise out of sneaker waves

Since 2005, more than two dozen confirmed fatalities in California and Oregon have been caused by so-called sneaker waves, which surge far ashore with little warning, sometimes catching beachgoers by surprise. Most beaches in the Pacific Northwest and California have posted signs warning visitors of the hazard, but few scientific studies have been done on sneaker waves and, currently, there is no consensus on their definition or origin.

1883 sea rescue informs new model of wind-wave interactions

Despite improvements in oceanographic observation, knowledge gaps remain about the interactions between ocean waves and wind blowing over the water’s surface. This is in part due to the difficulty of observing the ocean in high seas and windy conditions. In a new study in Geophysical Research Letters, however, researchers have used a historical record of a treacherous 1883 at-sea rescue — aided by the wave-calming effects of a fish-oil slick — to develop a model of how wind and water interact to form different sizes and types of waves.

Sailors right about sneaky rogue waves

Sailors are notorious for telling tall tales, including legends about monstrous “rogue waves” that appear at sea without warning. Oceanographers have traditionally dismissed such stories because they thought that unusually large waves would be preceded by series of waves of increasing size.
