Which areas of the ocean have the lowest salinity and why?
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.
What is the range for annual mean ocean surface salinites?
The annual mean ocean surface salinity typically ranges from about 30 to 37 practical salinity units (PSU). This variation is influenced by factors such as evaporation, precipitation, river runoff, and ocean circulation. Regions near the equator often have lower salinity due to high rainfall, while areas in subtropical regions can have higher salinity due to increased evaporation.
Where is the highest surface salinity found in the world ocean?
The highest surface salinity in the world ocean is found in the Red Sea.
What era two things that cause salinity to be lower in some ocean areas?
Lower rates of evaporation so more water to dilute it.
Does high evaporation rates in subtropics cause the surface ocean water to have a lower than average salinity?
No, high evaporation rates in subtropical regions typically lead to higher salinity in surface ocean waters. As water evaporates, it leaves behind salts and other dissolved substances, concentrating them in the remaining water. This results in elevated salinity levels, contrary to the idea of lower-than-average salinity.
Where is salinity the lowest?
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.
In regions of heavy precipitation is the salinity of surface waters is reduced?
Yes, in regions of heavy precipitation, the increased input of fresh water from rainfall can dilute the salinity of surface waters. This can occur in coastal areas and near river mouths where freshwater runoff mixes with the ocean water, reducing the overall salinity of the surface waters in those areas.
What lowers the salinity near the surface of the ocean?
evaporation
How is ocean water salinity different in tropical areas than at the north an south poles?
Surface water slainity is higher in tropical regions.
Is it true ocean water often has a lower salinity in warm areas than in cold areas?
yes come on people really.... think I'm 11 years old and i no that
Does industrial polutants affect ocean surface salinity?
hi
What area in the ocean is more likely to have the lowest salinity?
Areas near the poles like the Arctic Ocean will have the lowest salinity
