why the oceans located at the same latitude do not have same salinity?

The distribution of dissolved salts
in the oceans and adjacent seas varies in space and time.
Salinity is changed near the sea surface by precipitation
and evaporation of fresh water and by salty water produced
sea ice forms and excludes salt. Geographical variations
in inputs create regional differences in salinity at the sea
surface. As seawater circulates down into the ocean away
from the sea surface, it carries these differences along,
creating large-scale salinity patterns throughout the ocean.
Changes in time in the inputs at the sea surface also
affect the salinity distribution. By mapping the salinity
distribution and tracking changes in salinity over time,
much insight is gained into both the basic ocean circulation
and the processes that change the ocean circulation and
temperature distribution.

Salinity of seawater is determined by the factors like temperature, supply of fresh water and landlocked or open nature of sea. Hence, the effect of latitudinal location is comparatively less significant factor of on salinity of the sea. As a result the salinity of sea is not uniform even on the same latitude.E.g., the salinity of Indian Ocean and Atlantic Ocean is not same despite being on same latitude.
