WebJan 15, 2016 · Factors Affecting Ocean Salinity The salinity of water in the surface layer of oceans depend mainly on evaporation and precipitation. Surface salinity is greatly influenced in coastal regions by the fresh water flow from rivers, and in polar regions by the processes of freezing and thawing of ice. WebThe average temperature of sea water at depth of 200 metres is 12°C and at 1000 metres is 3.5°C. But, below this the rate of decrease becomes very slight and gradual. The average temperature of sea water at the depth of 5000 metres is only 1°C and below this, there is very little changes of temperatures. ADVERTISEMENTS:

WebJan 30, 2024 · Here is my list of five common factors that can disturb visibility underwater. 1. Particles in the Water Suspended particles of sand, mud, clay, or other bottom sediments affect the visibility underwater in much the same way as fog effects visibility on land – distant shapes become colorless, poorly-defined shadows. WebJul 3, 2024 · Light, oxygen, and temperature decrease with depth, while salinity and pressure increase. Due to these conditions, little resources for food are available in the mesopelagic zone, requiring the animals that inhabit this area to …

WebThe added freshwater makes the seawater less dense. This has caused the North Atlantic to become fresher over the past several decades and has caused the currents to slow. Water that is less dense will not be able to sink and flow through the deep ocean, which may disrupt or stop the pattern of ocean currents in the region. WebThe effects of salinity and temperature on sound speed are more important than the effect of pressure in the upper layers. Deeper in the ocean, salinity and temperature change less with depth, and pressure becomes the important controlling factor.
