The sonar mapping of the Challenger Deep was possible by its Simrad EM120 sonar multibeam bathymetry system for deep water. The sonar system uses phase and amplitude bottom detection, with an accuracy of better than 0.2% of water depth across the entire swath (implying that the depth figure is accurate to ± 22 metres (72 ft; 12 fathoms)).
How Deep Is the Ocean?" is a popular song written by Irving Berlin in 1932. The song was developed from an earlier Berlin song "To My Mammy" which was sung by Al Jolson in his film Mammy (1930). In the earlier song, the lyrics include the questions "How deep is the ocean?

In all parts of the ocean, deep ocean temperatures range between −2 °C (28 °F) and 5 °C (41 °F). [14] Constant circulation of water in the ocean creates ocean currents. Those currents are caused by forces operating on the water, such as temperature and salinity differences, atmospheric circulation (wind), and the Coriolis effect. [15]
Below this zone, the deep sea consists of the abyssal zone (ocean depth between 3-6 km, 1.8-3.6 mi) [14] and the hadal zone (6-11 km, 3.6-7 mi). [ 15 ] [ 16 ] Food consists of falling organic matter known as ' marine snow ' and carcasses derived from the productive zone above, and is scarce both in terms of spatial and temporal distribution.
In what may be the most technically exciting physics demonstrations I've ever seen, and perhaps the most jarring that will ever hit my stomach, Nvidia showed off their new ocean simulation at the ...
On average, the Atlantic is the saltiest major ocean; surface water salinity in the open ocean ranges from 33 to 37 parts per thousand (3.3–3.7%) by mass and varies with latitude and season. Evaporation, precipitation, river inflow and sea ice melting influence surface salinity values.
Emergency 4: Global Fighters for Life (known as 911: First Responders in North America) is a simulation video game developed by German studio Sixteen Tons Entertainment allowing users to manage emergency services on a variety of accidents and/or accident scenes.
