2. Describe how the above are 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 and climate.

3. Describe the characteristics of ocean waves.
3. Explain thedifferences among the storm surge, tsunami, tidal wave,and tidal bore. Explain the difference between sea, swell,and surf.
3. Explain how breakers are formed.

4. Draw a cross-section of underwater topography. Show what
is meant by:

a. Continental shelf
b. Continental slope
c. 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.

5. List the main salts, gases, and nutrients in seawater.Describe some important properties of water. Tell howthe animals and plants of the ocean affect the chemicalcomposition of seawater. Explain how differences inevaporation and precipitation affect the salt content ofthe oceans.

6. 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.
6. Describe the place and importanceof phytoplankton in the oceanic food chain.

7. 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.

b. 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.

c. Measure the water temperature at the surface, midwater,
and bottom of a body of water four times daily for five
consecutive days.* You may measure depth with a rock
tied to a line. Make a Secchi disk to measure turbidity
(how much suspended sedimentation is in the water).
Measure the air temperature. Note the cloud cover and
roughness of the water. Show your findings (air and
water temperature, turbidity) on a graph. Tell how the
water temperature changes with air temperature.

d. Make a model showing the inshore sediment movement
by littoral currents, tidal movement, and wave action.
Include such formations as high and low waterlines,
low-tide terrace, berm, and coastal cliffs. Show how
offshore bars are built up and torn down.

e. Make a wave generator. Show reflection and refraction
of waves. Show how groins, jetties, and breakwaters
affect these patterns.

f. Track and monitor satellite images available on
the Internet for a specific location for three weeks.

Describe what you have learned to your counselor.

DESCRIBE WHAT YOU LEARNED:

8. Do ONE of the following:

a. Write a 500-word report on a book about oceanography
approved by your counselor.

b. Visit one of the following:

(1) Oceanographic research ship

(2) Oceanographic institute, marine laboratory,
or marine aquarium
Write a 500-word report about your visit.

c. Explain to your troop in a five-minute prepared speech
“Why Oceanography Is Important” or describe “Career
Opportunities in Oceanography.” (Before making your
speech, show your speech outline to your counselor
for approval.)
