These were the REQUIREMENTS before the REVISIONS
which were made on January 1, 2004.
To see the current requirements
- Name four branches of oceanography. Describe at least five
reasons why it is important for people to learn about the oceans.
- Define salinity, temperature, and density, and describe
how these important properties of seawater are measured by the
physical oceanographer. Discuss the circulation and currents
of the ocean. Describe the effects of the oceans on weather
- Describe the characteristics of ocean waves. Point out the
differences among the storm surge, tsunami, tidal wave, and
tidal bore. Explain the difference between sea, swell, and surf.
Explain how breakers are formed.
- Draw a cross-section of underwater topography. Show what
is meant by:
- Continental shelf
- Continental slope
- Abyssal plain
Name and put on your drawing the following: seamount, guyot,
rift valley, canyon, trench, and oceanic ridge. Compare the
depths in the oceans with the heights of mountains on land.
- List the main salts, gases, and nutrients in sea water.
Describe the importance of these to life in the sea. What is
meant by Dittmar's principle? Why is it important?
- Describe some of the biologically important properties of
seawater. Define benthos, nekton, and plankton. Name some of
the plants and animals that make up each of these groups. Describe
the place and importance of phytoplankton in the oceanic food
- Do ONE of the following:
- (a) *Make a plankton net. Tow the net by a dock, wade
with it, hold it in a current, or tow it from a rowboat.
Do this for about 20 minutes. Save the sample. Examine it
under a microscope or high-power glass. Identify the three
most common types of plankton in the sample.
- Make a series of models (clay or plaster and wood) of
a volcanic island. Show the growth of an atoll from a fringing
reef through a barrier reef. Describe the Darwinian theory
of coral reef formation.
- *Measure the water temperature 1 foot below the surface
of a body of water four times daily (8 A.M., noon, 4 P.M.,
and 8 P.M.) for 6 consecutive days. Measure the air temperature.
Note the cloud cover and roughness of the water. Show your
findings on a graph. Tell how the water temperature changes
with air temperature.
- Make a model showing the inshore sediment movement by
littoral currents, tidal movement, and wave action. Include
such things as high and low waterlines, low tide terrace,
berm, and coastal cliffs. Show how the offshore bars are
built up and torn down.
- Make a wave generator. Show reflection and refraction
of waves. Show how groins, jetties, and breakwaters affect
- Do ONE of the following:
- Write a 500-word report on a book about oceanography
approved by your counselor.
- Visit one of the following: (1) an oceanographic research
ship, or (2) an oceanographic institute. Write a 500-word
report about your visit.
- Explain to your troop in a 5 minute prepared speech
"Why Oceanography Is Important" or describe "Jobs in Oceanography."
(Before making your speech, show your speech outline to
your counselor for approval.)
* May be done in lakes or streams.
