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. WebMar 2, 2024 · Of the three factors—temperature, salinity, and pressure—that have an effect on water density, temperature changes have the greatest effect. In the ocean, the thermocline (a water layer within which temperature decreases rapidly with depth) acts as a density barrier to vertical circulation.

Understanding why the sea is salty begins with knowing how water cycles among the ocean's physical states: liquid, vapor, and ice. As a liquid, water dissolves rocks and sediments and reacts with emissions from volcanoes and hydrothermal vents. This creates a complex solution of mineral salts in our ocean basins. … See more Surface winds drive currents in the upper ocean.

WebCold water is denser than warm water. Water with a high salt concentration ( salinity) is denser than water that has a lower salt concentration. Warm water rises above denser colder water, and bodies of water that have different temperatures can form layers according to their respective temperatures. WebMelting sea ice also changes ocean salinity (the sea ice only has a little salt in it, so it essentially releases fresh water as it melts) and ocean temperature. These changes can alter ocean currents, which also affect climate. Sea Level Rise Caused by Thermal Expansion of Water

WebThe salinity of oceans, particularly the Atlantic, has changed over the past four decades. When researchers measured the change in salinity levels of a “long transect (50° S to 60° N) through the western basins of the Atlantic Ocean” ( Curry, 2003). They found that the oceans freshened in areas north of 40° N and south of 25° S. WebThe salinity patterns of the surface waters of the Pacific are influenced largely by wind and by precipitation and evaporation patterns. The waters within the belt of calm and variable …

WebThe approximate change in the speed of sound with a change in each property is: Temperature 1°C = 4.0 m/s. Salinity 1PSU = 1.4 m/s. Depth (pressure) 1km = 17 m/s. Here is a typical sound speed profile for the deep, open ocean in mid-latitudes. Profile of speed of sound in water. Note the sound speed minimum at 1000 meters. WebOcean temperatures Ocean temperatures vary by location on Earth's surface. Toward the poles, the ocean is colder. Closer to the equator, the ocean is warmer. 3 main zones of ocean temperatures (increasing temp) Surface water, thermocline, deepwater ( increasing depth freezing) Cold water sinks. Warm water rises. As it rises and sinks in the ocean, …

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.
