Exam 17: Marine Resources

Ships are responsible for transporting almost all the world's crude oil production.

What marine resource has been rendered uneconomical due to the cost of excavation?

There are less than 500 species of fish, crustacean, and mollusks that are regularly harvested from the ocean.

Many harvested marine animals are sustainable because they are being caught below the maximum sustainable yield.

When a resource is present in a fixed amount, it is said to be:

Most of the exploitable oil fields are not easily accessible anymore.

Why is the extraction of wind so effective over or near the ocean?

What type of net has been particularly disruptive in the mistargeting of species?

How is petroleum formed in the ocean? How is it found and extracted when it is deep in the ocean?

What is bycatch?

In our actual economic market, prices reflect all the costs of goods and services that are harmful to the environment.

What tools do fishermen now employ to locate schools of fish?

What legislative policy or governing body reduced the number of dolphin deaths associated with tuna fishing?

What is the fastest-growing energy alternative to oil?

How much of the world's table salt is produced by the evaporation of seawater?

How much of the world's crude oil is found on the seafloor?

What are the three most valuable marine resources? How are they excavated from the ocean? Are these resources renewable or nonrenewable?

Aquaculture produces very little of the amount, perhaps ten percent, of fish consumed by humans.

How much of the fish stocks are considered to be overfished?

Small turbines have been placed in the Gulf Stream to harness this major ocean current.
