Over a lot of the sea, floor waters are in part remoted from deeper waters by means of alterations in density, that's why oceanographers painstakingly degree the 2 components— temperature and salinity—that ensure seawater density. as the densest water sinks, the sea is mostly layered, or stratified, with the densest water at the backside and the least dense on the floor. this is often visible in commonplace profiles of salinity, temperature, and density (Fig. three. 22). Deep water is generally chilly and dense, while the outside water is comparatively hot and “light. ” The water column within the ocean is generally stratified, with the least dense water on the floor and the densest water at the backside.
