Cordoba's Paco Acedo, who's best known for his diving expeditions in the Arctic and beneath frozen Russian lakes, has apparently decided to warm it up a bit and recently trekked through remote parts of Papua New Guinea, taking time to dive among some World War II-era wrecks at Guadalcanal in the Soloman Islands. 

His video summary of the trip is fascinating and simultaneously informative and hypnotically mesmerizing. The world, apparently, is a most interesting place.
