David Gallo: Deep ocean mysteries and wonders 1. 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?
2. 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.
