Question Sheet: Eyes on the Depths

SCIENCE

Before reading:

1. What are some challenges faced by scientists who study the deep sea?
2. What kinds of scientists study the oceans?

During reading:

1. Why does Edith Widder compare exploring the deep-sea to "driving a tank through Yellowstone"?
2. What are some advantages of the Johnson-Sea-Link II over other types of submersibles?
3. How does the Eye-in-the-Sea camera system work?
4. What is bioluminescence?
5. How do humans see differently from most deep-sea creatures?
6. What are some theories for how animals use bioluminescence?

After reading:

1. What might scientists be able to learn from a camera permanently placed at the bottom of the ocean that they could not learn from a temporary set-up? Are there any ways that a temporary camera set-up might be preferable to a permanent one?
2. How do animals navigate through the darkness in the deep ocean? Besides vision, what are other ways of understanding a landscape or environment?
3. Based on what you've learned about deep-sea exploration and communication, what kinds of tools and features do you think the next generation of submersibles should have?
4. Why might it be unnecessary for a deep-sea animal to see red light?
5. Compare how ecosystems work in the ocean and on land. What are some similarities and differences?
6. What do oceanographic institutions do?

SOCIAL STUDIES

1. Ocean conservation is very important to many people, but others, such as professional fisherman, have concerns about it. Set up a debate with a friend where one person argues in favor of Marine Protected Areas, which are like National Parks in watery environments. The other person argues against these marine reserves. For more information, see en.wikipedia.org/wiki/Marine_Protected_Area (Wikipedia), and www.panda.org/about_wwf/what_we_do/marine/
   our_solutions/protected_areas/index.cfm (World Wildlife Fund).
2. Which oceans do you think need the most protection? Which need the least? Explain your answers.

LANGUAGE ARTS

1. In the beginning of the article, the writer compares the ocean to Alice in Wonderland. Is that a good image to start the article with? How does the comparison change your understanding of the story? Why might the author of a science article mention a non-scientific book?
2. Widder's website contains lots of images of exotic deep-sea creatures. Visit her image gallery at www.oceanrecon.org/imagegallery_rightsrestricted.htm. Now, write a poem that carefully describes what one of these creatures looks like. Imagine that your reader has never seen this creature before.

MATHEMATICS

According to the conservation group MarineBio.org, an estimated 80 percent of all life on earth is found under the ocean surface. Yet, less than 10 percent of the oceans have been explored by humans. And according to the All Species Foundation, about 1.7 million species have been described. But there could be anywhere from 10 million to 100 million species on the planet. Based on these numbers, how many species do you think there are in the oceans? Explain your reasoning.
