The salinity would probably decrease because the ocean is made up of salt water.
In open ocean evaporation affects the salinity of the oceans, in closed oceans the lack of sunrays cause greater salinity levels.

The dip in salinity around the equator is primarily caused by the significant rainfall and river runoff typical of tropical regions. This heavy precipitation dilutes ocean water, reducing salinity levels. Additionally, the equatorial upwelling of nutrient-rich waters can bring deeper, less saline waters to the surface, further contributing to this decrease. Combined, these factors create a region of lower salinity in an otherwise saltier ocean.
Icebergs are the only freshwater part of an ocean. When icebergs melt, it results in a decrease in the salinity of ocean water.
The addition of rain and river water to the ocean does not decrease its overall salinity because rain and river water are fresh water sources with low salinity levels. While these sources do mix with the ocean water, the vast volume of the ocean dilutes the impact of the fresh water input, thus maintaining the ocean's overall salinity.
Salinity in oceans decrease when near a river because the river adds fresh water, which lowers the percentage of salt in the water, causing the salinity to decrease.
The main reasons for higher salt content in surface ocean water are evaporation and formation of sea ice. As water evaporates, salt is left behind, causing an increase in salinity. In regions where sea ice forms, the salt is expelled, further increasing the salinity of the remaining water.
