Introduction

why study the oceans
Why Study the Oceans?
  • Scientific curiosity
  • Travel
  • Commerce
  • Food
  • Minerals including salt
  • Fresh Water
  • War/Defense
earth the water planet
Earth—The Water Planet
  • Water 71% of Earth surface area
    • oceans and seas
  • Land 29% of Earth surface area
    • includes lakes, streams, rivers
  • Earth is a water planet but efforts are concentrated on land
  • Oceanography studies all aspects of oceans
oceanography includes all aspects of study but there are four main areas
Oceanography includes all aspects of study, but there are four main areas.
  • Geological Oceanography
  • Chemical Oceanography
  • Physical Oceanography
  • Biological Oceanography
geological oceanography
Geological Oceanography
  • Size and shape of ocean basins
  • Ages of the sea floor
  • Ocean rocks versus continental rocks
  • Sediments

that cover

the seafloor

chemical oceanography
Chemical Oceanography
  • Sea water composition
  • Extracting useable materials dissolved in seawater
  • Obtaining fresh water from seawater
  • Dissolved

gases and their

exchange

between sea

and air

  • Buffer

reactions

physical oceanography
Physical Oceanography
  • Water motion—waves, currents, tides
  • Transmission of energy—sound, heat, light
  • Water masses
  • Pressure
biological oceanography
Biological Oceanography
  • Life of the sea
  • How sea life affects environment
  • What life needs for optimum development
  • Food chains
  • Migration patterns
  • Habits of food fish, prey, and predators
marine engineering
Marine Engineering
  • Equipment to secure samples 7 miles below ship
  • Breakwaters, piers, seawalls
  • Extracting power from energy of waves and tides
  • Designing submarines and other submersibles
  • Drilling platforms for oil and gas exploration
  • Nuclear waste disposal?

oceans and meteorology
Oceans and Meteorology
  • Oceans determine world climatic conditions
  • Oceans affect local weather
  • Oceans are dominant factor in heat budget
  • Oceans are the

“flywheel of

atmospheric

circulation”

marine ecology

A sea otter feeding offshore Southern California. They were hunted almost to extinction, mainly for fur.

Marine Ecology
  • Pollution
  • Extinction of marine species
  • Loss of wetlands
  • Negative environmental impacts
