Ocean water is not the same everywhere. For example, in the place where rivers flow into it, water areas with a unique composition of water and wildlife are formed. Is it possible to determine the boundary between the river and the sea, how hydrologists study river plumes, how the mixing of water affects the inhabitants of the depths and the entire world ocean, we will discuss in new release Podcast “Scientist Cat” on the radio Sputnik.
