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.

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.
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.
The boarded windows block the view of the ocean, but he can still hear the rumbling, followed by a few seconds of respite before another wave slams against the wall. ... Nor'easter sends enormous ...
This occurs because the Earth is rotating. The rotation of the earth results in a "force" being felt by the water moving from the high to the low, known as Coriolis force . The Coriolis force acts at right angles to the flow, and when it balances the pressure gradient force, the resulting flow is known as geostrophic.
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.
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.
