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.
A plunging wave breaks with more energy than a significantly larger spilling wave. The wave can trap and compress the air under the lip, which creates the "crashing" sound associated with waves. With large waves, this crash can be felt by beachgoers on land. Offshore wind conditions can make plungers more likely.
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.
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. "What happens here is the ...
Wave pounding is the 'sledge hammer' effect of tonnes of water crashing against cliffs. It shakes and weakens the rocks leaving them open to attack from hydraulic action and abrasion. Eroded material gets carried away by the wave. Wave pounding is particularly fierce in a storm, where the waves are exceptionally large, and have a lot of energy ...
Atmospheric Rossby waves on Earth are giant meanders in high-altitude winds that have a major influence on weather. These waves are associated with pressure systems and the jet stream (especially around the polar vortices). [2] Oceanic Rossby waves move along the thermocline: the boundary between the warm upper layer and the cold deeper part of ...
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.
