Underwater acoustics (also known as hydroacoustics) is the study of the propagation of sound in water and the interaction of the mechanical waves that constitute sound with the water, its contents and its boundaries. The water may be in the ocean, a lake, a river or a tank. Typical frequencies associated with underwater acoustics are between 10 ...
Oxygen minimum zone. The oxygen minimum zone ( OMZ ), sometimes referred to as the shadow zone, is the zone in which oxygen saturation in seawater in the ocean is at its lowest. This zone occurs at depths of about 200 to 1,500 m (700–4,900 ft), depending on local circumstances. OMZs are found worldwide, typically along the western coast of ...

Echo sounding or depth sounding is the use of sonar for ranging, normally to determine the depth of water ( bathymetry ). It involves transmitting acoustic waves into water and recording the time interval between emission and return of a pulse; the resulting time of flight, along with knowledge of the speed of sound in water, allows determining ...

An earworm happens when you have the “inability to dislodge a song and prevent it from repeating itself” in your head, explains Steven Gordon, M.D ., neurologist at UC Health and assistant ...
It is a flashback from Ranbir and Deepika's time in Corsica. Both of the leads are dancing on their own beat – they have headphones on – in the middle of a scenic landscape. Ranbir leans in close to Deepika, removes her headphone slightly, and says: "Mujhe yakeen ho gaya hai ki Teja ka sona tere paas hai!" Deepika smiles.
The stratified layers limit how much vertical water mixing takes place, reducing the exchange of heat, carbon, oxygen and particles between the upper ocean and the interior. Since 1970, there has been an increase in stratification in the upper ocean due to global warming and, in some areas, salinity changes. [13]
