PHYSICAL OCEANOGRAPHY
Why Study the Physics?
-
Utility: Transport, recreation, swimming, boating, fishing, surfing diving
Atmospheric Influence: Regulates climate and weather patterns
Processes of interest: Air-sea interactions (fluxes of heat transport, and ocean influence on climate and weather pattern)
Breathable Oxygen
- Over 50% source of world O2
- Stores CO2 more than 50 times than the atmosphere
-
Continentality: Measure of how much a region's climate is influenced by being far from the moderating effects of the ocean
Environmental Impact:
- Severe continentality creates harsh inland conditions
-
Temperature Extremes
- Land cools down and heats up much faster than water
-
-
Precipitation patterns
High Continentality = Less Total Rainfall (mosit air masses lose their moisture before travelling deep inland)
-
Oceanography
- Study of the ocean
- Focuses on its character as an evironment
-
PROPERTIES OF WATER
Hydrogen Bonding
- Strong intermolecular attraction
- Adjacent molecules align along their bonding orbital axes to create strongly order assemblies
Strong intermolecular attractions
Opposites attract! Positive H atom --> Negative side of neighboring molecule
-
Molecules stick together tightly and organize themselves into neat, predictable patterns
Create strongly ordered assemblies:
- Molecules build highly structured, organized networks instead of chaotic connections
Thermal Properties:Water has the highest heat capacity, heat of vaporization, surface tension, and dielectric constant (ion-insulating capability) of all substances.
- Heat of fusion (heat needed for transition from solid to liquid) - Greater than any substance except ammonia
Molecular Level
-
Dipole
Slightly positive & Negative ends
- Asymmetric charge distribution creates a net separation of charge in space
