Do the oceans mix?: The Atlantic and Pacific meet at Cape Horn, at the southernmost tip of Chile, South America. In this region, a strong current carries water from west to east, sweeping water from the Pacific into the Atlantic.

• We came across reports by BBC Science Focus and Princeton Library, which mentioned that the two oceans do mix together.

• BBC noted the two oceans mix and are not separate. Though there is a difference between their densities and salinity levels, water currents and eddies cause both oceans to mix gradually.

• However, ocean water may not always appear to mix due to surface currents on water, which play a role in how water flows on the ocean's surface, as per the Encyclopaedia Brittanica.

• The region experiences strong currents; hence, the water flows west to east, "sweeping water from the Pacific into the Atlantic."

• BBC also wrote, "in reality, there’s no border between them, and currents continually flow between them and mix their waters."

• Additionally, the report mentioned that light-coloured, sediment-rich freshwater from melted glaciers meet the dark, salty ocean water in the Gulf of Alaska and mix together.
