The talk features some amazing photography by Brian Skerry, who also gave a TED talk recently (you can see it here). During the talk you'll also see parts of the Phoenix Islands seamount fly through that was posted on this blog in March.
The ocean stories don't end with the talk, though. Read more from Greg with his posts from the 2009 PIPA expedition and the 2008 Sea of Cortez expedition. You'll also want to track down the inside story of the other adventures he mentions. The 2001 Antarctica Expedition is covered in the book Ice Island: Expedition to Antarctica's Largest Iceberg, and this documentary.

You can also find out more from the people mentioned in the talk. For example, the dive master that first interested Greg in the Phoenix Islands, Rob Barrel, wrote his recollections of the genesis of PIPA in this post, and Dr. David Obura has also posted his observations of coral bleaching and conservation here. See more of the visionary leader Greg describes, president Anote Tong, in these award ceremony photos from is visit to the New England Aquarium in 2008.
