This dataset shows the salinity (concentration of salt) differences throughout the ocean. These variations in salinity have large-scale effects on Earth's water cycle and ocean circulation.

Science: Because there is a huge difference in salinity between the clear water that comes from melting glaciers, which is cool and low in salt, while the water from the second ocean has a high salt concentration. Therefore, the two oceans have different densities, which makes them almost impossible to mix. Credit: Comrade Phils | All Facts Newspaper | Facebook

The notion that the Atlantic and Pacific Oceans do not mix is a misconception rooted in visual phenomena rather than scientific reality. While certain areas, such as the Gulf of Alaska, may display a distinct line where two bodies of water meet, this is due to differences in water properties like salinity, temperature, and sediment content, not a lack of mixing. In regions where these differences are pronounced, such as when freshwater from glaciers meets saltwater, the less dense freshwater can
