The lowest areas of salinity in an ocean are near where fresh water rivers empty into them. This is because the influx of fresh water creates an area of lower salinity compared to the remainder of the ocean.
The salinity of the ocean was much higher than I thought it would be.
The top most layer has more salinity. But ignoring thermo-haline currents.
Salinity can vary because of water temperature, rivers emptying into the ocean and mixing with ocean water, ice forming or melting, evaporation and precipitation. I think temperature is the biggest reason.
Storms at sea. The evaporated water falls back into the ocean with no net effect on salinity.
the most dense part of the water is in the pacific ocean. it is located near the middle of the ocean. go 50 miles past the middle and you there. Make sure you go north though. It's an ocean trench. HOPE THIS HELPS>>>>>EVEN THOUGH IS'T WRONG...
Areas near the poles like the Arctic Ocean will have the lowest salinity
The ocean with the lowest salinity is the Arctic Ocean. This is due to factors such as extensive melting of ice and low evaporation rates, which dilute the salt concentration in the water.
Salinity is generally lowest in areas where freshwater sources like rivers and streams meet the ocean, such as estuaries and deltas. Other factors like heavy rainfall and melting ice can also contribute to lower salinity levels in certain regions.
yupper!
Red Sea and Persian Gulf are the areas with the highest salinity. Then the areas with lowest salinity would be the polar seas (or seas near to the polar tips), and sometimes some seas near a fresh body of water. For example, the South American area near Amazon River only has an average salinity of 28 o/oo. The Baltic Sea may have an average salinity of 5 o/oo. Hope this helps!!
The body of water with the lowest salinity is typically freshwater, such as rivers and lakes. Among larger bodies of water, the Baltic Sea is known for having low salinity levels due to its significant freshwater inflow from rivers and limited exchange with oceanic waters. In general, salinity levels decrease in areas where freshwater mixes with saltwater.
because ocean water leaves salt behind when it freezes
Salinity is a measure of how salty water is. Ocean water is more salty in some places than in others. The answer is yes, places where rivers pour fresh water into the ocean have low salinity because fresh water is normally cold and in warm areas, ocean water evaporates quicker. When this happens, salt is left behind and the ocean water has a higher salinity.
The Antarctic Intermediate Water (AAIW) are the low salinity waters found in the Southern Ocean.
The cryosphere, which includes ice and snow, influences ocean salinity primarily through processes like melting and freezing. When ice melts, it releases freshwater into the ocean, decreasing salinity in the surrounding waters. Conversely, when seawater freezes, it leaves behind salt, increasing salinity in the remaining liquid water. Additionally, changes in precipitation and runoff from snowmelt can further affect salinity levels in coastal areas.
Where a major river enters. Where a large glacier enters. Where an ice shelf is melting. Upon reflection, about one half of the ocean will have a salinity less than the average.
Evaporation near the equator increases the salinity of the ocean water because it removes fresh water and leaves behind the salts, making the water more saline. This can lead to higher salinity levels in tropical regions compared to other areas of the ocean.
