because of the low evaporation, more inflow of the river waters and fresh water release from melting icebergs
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.

Fresh Water
Salinity in the ocean is highest in regions where evaporation is high and precipitation is low. Density in seawater is determined by both temperature and salinity.
The Arctic Ocean is stratified and has limited vertical mixing of water because of its cold temperatures and the presence of a halocline, which is a layer with a sharp decrease in salinity. This halocline acts as a barrier to vertical mixing by preventing the movement of water between different layers.
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.
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.
Yes, yes they do!!
The warm, low salinity waters from Pacific are transported into Indian Ocean's South Equatorial Current.
Because of the solidification of the water under low temperatures. The water is "turned" into ice, leaving the salt behind. So the salt is left in the water, with the freshwater turned into ice floating on top. If the glaciers melt, the salinity will decline, because this new freshwater will dilute the salty waters.
What causes low salinity in the oceans at high latitudes?In subtropical latitudes, high surface evaporation creates high salinity near the sea surface. In subpolar latitudes, high precipitation creates low salinity near the sea surface. As these waters flow into the ocean interior, they create layers of high and low salinity.
Low salinity refers to the condition of water having a lower concentration of dissolved salts compared to seawater. This can occur in areas where freshwater input dilutes the salt content or due to specific environmental conditions such as rainfall or melting ice. Low salinity levels can have impacts on aquatic ecosystems and influence ocean circulation patterns.
