What are the physical properties of sea water?
- Physical properties of sea water, general distribution of salinity, temperature and density, waves and currents, ocean atmosphere interactions.
What is the chemical composition of seawater?
- Detailed composition: abundance of the elements in seawater Salinity: the main salt ions making the sea salty Density: the density of sea water depends on temperature and salinity Dissolved gases: the two important gases to life, oxygen and carbondioxide. Limiting hydrogen ions and ocean pH.
What causes variations in seawater properties?
- Variations in the seawater properties are caused by many factors including atmospheric heating and cooling, precipitation, and for dissolved oxygen, gas exchange with the atmosphere and biological respiration. Listed below are some standard time series plots generated on a daily basis to reveal the state of the ocean at each site.
How many specific heats does seawater have?
- Strictly speaking, seawater has three specific heats, all approximately equal to the value for pure water of 25,200 ft2/ (s2 °R) 4210 m2/ (s2 K). EXAMPLE 1.7 The pressure at the deepest part of the ocean is approximately 1100 atm. Estimate the density of seawater at this pressure.
