Problem
1) David Gallo: Deep ocean mysteries and wonders
a) At the time this video was filmed (2007), what was Gallo's estimate of the percentage of earth's oceans that had been investigated? How might this impact not only how we view the oceans, tides, and the entire marine ecosystem, but also the world and climate in general?
b) Just as the unit describes many amazing ecosystem creatures, Gallo also shares some incredible species that were observed at the bottom of the ocean. Briefly describe several of the creatures or discoveries discussed and what makes them so interesting.
2) Laura Robinson: The secrets I find on the mysterious ocean floor
a) Briefly describe what Robinson and her colleagues are trying to understand. Why does she think the ocean has a lot to do with this?
b) Robinson illustrates how she and her team are using corals to learn more about the ocean's composition long ago. Briefly summarize what Robinson details about ancient ocean feedbacks.
c) The unit discusses primary and secondary succession. What are primary and secondary successions? How does primary or secondary succession relate to this video?
d) What did you find to be the most astonishing or interesting thing Robinson discovered on the deep ocean floor? Why?
3) How Do Ocean Currents Work?
a) What drives ocean currents? What modifies these motions?
b) What are surface currents? What drives them?
c) What are deep ocean currents? What drives them?
d) What is the Global Conveyor Belt? Where is it located? What is happening to this Belt?
