Is seawater a water or a sediment?
Seawater is mostly water (H2O). In fact it is about 96.5 wt % water. Surface sediments are also mostly water. Most fine-grained surface sediments have a porosity ( = volume of pores to volume of solids) of greater than 90%.
What is the most important thermodynamic property of seawater?
The most important thermodynamic property of seawater for studies of oceanic circulation is its density (denoted ρ). Typical densities span a narrow range (Table 1, Figure 1c). It is therefore conventional in discussions of the ocean to use a derived variable σ for density, where
How does seawater affect organisms?
The physical and chemical properties of seawater have a great effect on organisms, varying especially with the size of the creature. As an example, seawater is viscous to very small animals (less than 1 millimetre [0.039 inch] long) such as ciliates but not to large marine creatures such as tuna.
What are the physical and chemical properties of seawater?
Marine ecosystem - Salinity, Temperature, Oxygen: The physical and chemical properties of seawater vary according to latitude, depth, nearness to land, and input of fresh water. Approximately 3.5 percent of seawater is composed of dissolved compounds, while the other 96.5 percent is pure water.
