The Montauk docks were abuzz with disbelief and disappointment Saturday over the removal of their top Coast Guard officer, stripped of his duties after he and a subordinate took a pair of rescue boats on training exercises for which they were not certified.

And one photographer who created dramatic shots of those exercises in heavy surf after Hurricane Bill passed Long Island in August says he’s despondent to think he might have made it look more dangerous than it was.

Chief Petty Officer James Weber, a well-liked, 21-year Coast Guard veteran, has been reassigned from the Montauk Station to the Guard’s New Haven office. He will lose his command permanently unless he prevails in an appeal. A Guard spokeswoman said Saturday Weber has not decided whether to appeal. He could not be reached for comment. Senior Coast Guard officials said Friday he had violated procedures vital to crew safety. Read More at Newsday.com

Every so often mariners report the sighting of a huge wave towering up to 30 m above the regular swells of the ocean surface. No-one is sure why these rogue waves form, but now physicists in the US and Germany have managed to produce equivalent optical rogue waves by launching laser pulses into photonic-crystal fibres. Having performed computer simulations of the optical system, the researchers suggest that optical rogue waves, and therefore oceanic rogue waves, are seeded by noise.

A photonic-crystal fibre is a transparent strand containing hundreds of regularly-spaced air holes running throughout its length. The alternating refractive index produced by this structure has a non-linear effect on light waves, shifting their frequency depending on the wave intensity.

When a wave pulse — which comprises many waves with a bell-shaped distribution of frequencies — enters a photonic crystal fibre, its frequency spectrum is broadened. Rogue waves are examples of wave pulses, but their short, sharp nature requires too broad a frequency spectrum to be produced by this process alone.
