seawater
Salty marine fluid
Seawater is the salt water that fills the world's oceans and seas.
It contains dissolved salts—primarily sodium chloride—along with minerals, making it undrinkable without desalination.
The seawater was too cold for swimming.
Scientists study seawater composition to understand marine ecosystems and climate patterns.
