Question
Why salinity increase with depths
Answers
GPT 3.5
Salinity generally increases with depth in the ocean due to a few different factors.
1. Evaporation: Near the surface, ocean water can evaporate, leaving behind dissolved salts and increasing the salinity of the remaining water.
2. Mixing: Surface currents and winds can cause mixing of surface waters with deeper waters. This can bring saltier waters from depth up to the surface, contributing to an overall increase in salinity as you go deeper.
3. Thermohaline circulation: The global ocean circulation system involves the movement of water masses based on differences in temperature and salinity. In regions where cold, salty water sinks and moves towards the equator, such as in the North Atlantic Ocean, this can lead to an increase in salinity with depth.
Overall, these processes contribute to a general trend of increasing salinity with depth in the ocean.
