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 salinity used in a sentence?
The salinity of the ocean was much higher than I thought it would be.
Which layer of the ocean has higher salinity?
The top most layer has more salinity. But ignoring thermo-haline currents.
List the reasons for variations in salinity in the various oceans?
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.
Which process does not add salts to seawater?
Storms at sea. The evaporated water falls back into the ocean with no net effect on salinity.
Instruments for measuring salinity and altitude?
a refractometerHydrometerIt is actually a salinity meterHydrometer is the most common tool used to measure salinity levels.
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
Which is the ocean with the lowest salinity?
Arctic ocean
Would the salinity of the ocean probably be the lowest near a river?
yupper!
Which areas of the ocean have high salinity Which have low salinity?
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!!
Why is salinity higher in areas with more ice?
because ocean water leaves salt behind when it freezes
True or false places where rivers pour fresh water into the ocean have low salinity?
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.
What are three areas in the ocean where salinity may be less than average?
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.
What waters near antarctica with the combination of the lowest sea temperatures and highest salinity and determine the approximate density of these waters?
The Antarctic Intermediate Water (AAIW) are the low salinity waters found in the Southern Ocean.
How is ocean water salinity different in tropical areas than at the north poles?
Earth has only one North pole.
Why Ocean Salinity increasing?
When evaporation occurs at a rate faster than precipitation, the net result is that salt is left behind and the salinity in the oceans will increase. Of course, new salt is brought into the ocean by rivers and deposition of salts on the sea floor takes salt out of the ocean. As a whole, the salinity of the ocean (total salt everywhere) has not changed for millions of years since these input and removal processes are in balance. The increased "saltiness" created by the imbalance between precipitation and evaporation in certain areas of the ocean (some very large) is balance by areas that are fresher so the whole ocean is not getting saltier.
Where is salinity the lowest?
it is at its lowest when its at the surface of the water because it has low density
The salinity of the ocean?
You could increase the salinity of the ocean by adding salt or removing water (ie: by evaporation).
