Ocean water salinity at equator

ocean water salinity at equator How do temperature and salinity affect mixing in the oceans es2202 variations in a salty ocean salinity is a measure of how much salt is dissolved in water the average salinity of seawater for all earth's oceans is about 35 grams of dissolved salts per kilogram of seawater.

In fact the reverse is true, the salinity of the oceans is actually higher in tropical latitudes although all the points raised in your question are certainly true, evaporation is far and away the dominant factor the level of evaporation is such that it concentrates the ppm of salt in the water to a greater extent. Effect of salinity the ocean does not have a uniform salinity as ocean water flows toward the polar region from the equator, it passes the subtropical these concepts of density dependence on temperature and salinity explain the linkage of surface water to the abyssal (deep ocean) circulation. Salinity[edit] the makeup of the oceans is paramount to all these interrelated functions the ocean is composed of primarily water, however the the temperature maximum along the equator results in low density seawater and low salinity there as well, as does the influx of fresh water from melted ice.

The glaciers lower the salinity of the water going towards the tropics, there is a subtle increase in heat, this is caused by lots of radiation as we go towards the equator we notice that the salinity is very low, this is because there is high precipitation and this makes the water salinity drop drastically. Warm equatorial waters therefore move slowly along the surface towards the poles while heavier cold waters of the polar areas creep slowly towards the equator along the bottom of the sea oceanic salinity affects the density of ocean water and density variation causes ocean currents. The temperature of the ocean water near the equator is more than that of the temperature near the arctic and the antarctic circles salinity is the percentage of salts dissolved in the sea or ocean water.

The south equatorial current (sec) as represented by the mariano global surface velocity analysis (mgsva) the sec is a broad westward flow that is the primary basin-scale surface ciculation in the equatorial atlantic click here for example plots of seasonal averages. I read that thermohaline circulation is caused by cold and saline water sinking, while warm and less dense water rises link i understand that saline water is more dense. The great ocean conveyor moves water around the globe the ocean conveyor gets its start in the norwegian sea, where warm water from the gulf stream heats the atmosphere in the cold northern latitudes this cold bottom water flows south of the equator all the way down to antarctica. Salinity of ocean water: we know that sea water is salty the surface temperature of the ocean water mainly depends on the latitude and season it is to be noted that water is heated and cooled rather usually, the temperature of ocean water decreases from the equator to the polar regions.

The average salinity of the sea water is 35 per thousand it means that in one kilogram of sea water, there are 35 grams of dissolved salts in the atlantic ocean, the salinity near the tropics is about 37% (per thousand) on the other hand, near the equator, there is heavy rainfall, high relative. The salinity of oceans ranges from 35 to 37 ppt that's the same as saying 35% to 37% of ocean water is salt ocean salinity is changed by hurricanes which dump hundreds of trillions of gallons of freshwater on the ocean surface what do you think why is sea water less salty near the equator. Water takes a long time to get warm once water is warm it stays warm longer this is why the ocean helps heat more of the world equatorial upwelling the ocean around the equator receives the most sunlight the salinity is lower at the equator because it rains more there rain dilutes the ocean.

The salinity of ocean water is measured in parts per thousand high salinity values are over 35 parts per thousand, while values below this are considered low around the equator, where there is large amounts of rainfall, surface salinity rarely exceeds 34 parts per thousand. -2 °c sea water of average salinity freezes (the higher the salinity, the lower the freezing temperature) so near the north pole has in the bottom layers of the global ocean temperatures at all latitudes, low: +2 °c at the equator to -2 °c in the arctic and antarctic which leads to the fact that. Variation in salinity the salinity of the ocean varies from place to place, especially at the surface much of the ocean has salinity between 34 ppt however, the effect is greater if the salty water gets cold, as temperature has a greater effect on density than salinity does a combination of high salinity. Seawater is water from a sea or ocean on average, seawater in the world's oceans has a salinity of approximately 35%, or 35 parts per thousand the planet's freshest (least saline) sea water is in the eastern parts of gulf of finland and in the northern end of gulf of bothnia, both part of the baltic sea.

  • The ocean water is constantly churning underneath, bringing nutrients up to the top the difference in density of cold water versus density of warmer water is when the temperature, density or salinity of a layer changes rapidly, this region is referred to as a cline thermoclines, or areas of rapid change in.
  • The equatorial region of low salinity ocean water lies below an atmospheric region called the intertropical convergence zone the intertropical convergence zone moves about the equator as the intense heat in the equatorial area produces a rising mass of moisture-laden air, thereby creating.
  • Water plays a central role in the climate system its ­density varies depending on salinity and temperature 18 the worldwide ocean currents of the thermohaline circulation system are extremely complex the flow of cold, saline surface water (blue) downward and toward the equator.

Ocean currents mariners have known for many centuries that the ocean contains currents that flow along generally consistent paths the second effect of the sun is to alter the density of the ocean surface water directly by changing its temperature and/or its salinity. Salinity salinity is the amount of dissolved solid material in water since the factors that determine the concentration of salts in seawater are not constant from the equator to the poles, the 9 below the halocline the salinity of ocean water (increases rapidly, remains fairly constant, decreases rapidly. What is the salinity of the ocean water • the equator accounts for only 35% salinity which is equal to the average salinity of the oceans and the seas • the highest salinity is observed between 200-400n because this zone is characterized by high temperature, high evaporation but significantly. Salinity decreases in case fresh water is added to the ocean water it may be through any of the processes such as precipitation, influx of fresh water by rivers, surface runoff or the melting of snow and ice etc in the equatorial region, the cloudiness and high relative humidity retard evaporation.
