properties
What are the unique properties of water
Hydrogen and oxygen
what is salinity ?
the content of dissolved salt.
High viscosity easier to float
Marine effect
3.5%
Six major ions make up 99% of seawater
Sodium, magnesium, calcium, potassium, chloride, sulfate
Shared electrons between hydrogen and oxygen
Covalent bonds
what is desalination ?
process of obtaining freshwater from saltwater.
Where in the ocean would you find the least viscous seawater?
Equator
Sea surface salinity is controlled largely by?
The many elements in seawater at concentrations less than one part per million
Trace elements
Electrons are shared unequally
Strong dipole
What is covalent bonds?
Shared electrons between hydrogen and oxygen
Resistant to flow
Viscosity
What's the Dead Sea ppt?
300-400 ppt
The source of salt in the sea is from?
Weathering , erosion and dissolution of the rocks that make up the Earth's crust
Polarity water can form weak bonds called?
Hydrogen bonds
What is an ocean acidification ?
an effect that has resulted in a decrease in ocean pH.
Heat lowers viscosity, cold raises viscosity
The Red Sea and Persian Gulf salinites ppt?
40-44 ppt
Salt removal pathways
Tropical and subtropical evaporation, chemical reactions, biological removal
60-90% by volume in body and cells
Water
What is compensation depth?
High viscosity harder to swim, more drag
Marine Effects
Makes up 86% of dissolved ions in seawater
Sodium Chloride
What's the most important removal pathway?
Adsorption
