A Royal Caribbean cruise ship ran into high winds and rough seas in the Atlantic Ocean, forcing the Florida-bound vessel to retreat back to its home port in Cape Liberty, New Jersey.
Wind gusts of over 100 mph were recorded in the nearby town of Duxbury, while the highest gust of the day was reported in the Cape Cod town of Truro, which reached 113 mph.
Upsweep is an unidentified sound detected on the American NOAA's equatorial autonomous hydrophone arrays. This sound was present when the Pacific Marine Environmental Laboratory began recording its sound surveillance system, SOSUS, in August 1991. It consists of a long train of narrow-band upsweeping sounds of several seconds in duration each.

Research on the origin of seismic noise [1] indicates that the low frequency part of the spectrum (below 1 Hz) is principally due to natural causes, chiefly ocean waves.In particular the globally observed peak between 0.1 and 0.3 Hz is clearly associated with the interaction of water waves of nearly equal frequencies but probating in opposing directions.
McMurdo Sound experiences katabatic winds from the Antarctic polar plateau. McMurdo Sound freezes over with sea ice about 3 metres (9.8 ft) thick during the winter. During the austral summer when the pack ice breaks up, wind and currents may push the ice northward into the Ross Sea, stirring up cold bottom currents that spill into the ocean basins.
Hazardous conditions developed along the coast even well ahead of the storm's landfall when Ophelia crashed onshore near Emerald Isle, North Carolina, around 6:15 a.m. EDT Saturday.
The SOFAR channel (short for Sound Fixing and Ranging channel), or deep sound channel (DSC), is a horizontal layer of water in the ocean at which depth the speed of sound is minimal, in average around 1200 m deep. [2] It acts as a wave-guide for sound, and low frequency sound waves within the channel may travel thousands of miles before ...
