👉 The salt fluid, also known as brine, is a dense, electrically conductive solution primarily composed of sodium chloride (NaCl) dissolved in water. This fluid is found in the deep ocean, particularly in the haloclines and pycnoclines where salinity changes rapidly with depth. The high concentration of dissolved salts gives the salt fluid its exceptional conductivity, allowing it to carry electric currents over long distances. This property is crucial for various marine processes, including the generation of electric fields by marine organisms like sharks and rays, which use these currents to detect prey. Additionally, the salt fluid plays a significant role in ocean circulation and the global thermohaline circulation, influencing climate patterns on Earth.
