As salinity increase, it also reduces the freezing point of water. Density is a critical element in ocean circulation and will be discussed in more detail below. The hydrogen bonds make water an effective solvent. All elements and compounds dissolve in water to a greater or lesser extent. Particles settle faster in tropical water than they do in polar water.
Fish use more energy swimming in cold water than they do swimming in warm water.
G. Sound transmission in water 1. Sounds generated there will travel further without dissipation. Dissolved Solids in Seawater - Ocean water contains many dissolved elements and compounds. Virtually every element in the Earth system is present in seawater to some degree. Salinity in the open ocean varies between 30-40 ppt.
