Introduction



Do we care about the oceans
Do we care about the oceans?



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 four main areas.

  • 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 four main areas.

  • 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 four main areas.

  • Water motion—waves, currents, tides

  • Transmission of energy—sound, heat, light

  • Water masses

  • Pressure


Biological oceanography
Biological Oceanography four main areas.

  • 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


There are many other areas of oceanography including
There are four main areas.many other areas of Oceanography, including:

  • Engineering

  • Meteorology

  • Ecology


Marine engineering
Marine Engineering four main areas.

  • 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 four main areas.

  • 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


Textbook not required
Textbook—not required hunted almost to extinction, mainly for fur.

  • An Introduction to the World’s Oceans (tenth edition)

  • by Sverdrup and Armbrust—published by McGraw-Hill

  • Not required, but strongly recommended


Syllabus review
Syllabus Review hunted almost to extinction, mainly for fur.

  • We will quickly review the syllabus in class

  • Log into the class WebCT site to see the full syllabus

  • Pay special attention to the class calendar, announcements posted, and emails for important items.


Course packs
Course Packs hunted almost to extinction, mainly for fur.

  • Required

  • Include all PowerPoint slides

  • Available in the bookstore
