Question

ocean located at same latitude do not have same density

Answer 1

you may be asking about salanity

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.
