摘要：
Hydration numbers of basic ions in sea water (SW) are found from a proton relaxation rate of 1/T1 in SW and model solutions. A possibility for the formation of three-layer hydrate shells around main SW cations and two-layer shells around anions is ascertained. About half of water molecules is in influence zones of ions in sea water that correlates with a double shift in the baric dependence maximum of T1 to a smaller pressure in SW relative to pure water.
