Diverse offerings on cabler's upcoming schedule

National Geographic Channel is prepping a summer slate with premieres of four weekly series and two miniseries, along with the return of four shows.

“Expedition Great White,” bowing June 6, follows 126-foot-long ship “Ocean” on its study of great white sharks off the coast of Baja California. Dr. Michael Domeier is the leader of the expedition, which also includes in its crew former ESPN2 “Offshore Adventures” host Chris Fischer and actor Paul Walker. NatGeo sneak previewed the series last year before moving forward with this year’s series.

Also coming this summer from NatGeo is “Nat Geo Amazing!” airing Fridays beginning July 9 and focusing on unbelivable stories across the planet — human, animal or otherwise.

NatGeo will launch Monday primetimer “Monster Fish” July 19 and companion series “Fish Warrior” a week later. “Monster Fish” has a seven-episode order, while “Fish Warrior” has six.

NatGeo has also slated two miniseries: the five-hour “How the Earth Changed History,” examining the planet’s effect on its people, for three nights beginning June 20, and “Drugs, Inc.,” a four-part special beginning July 11.

Summer also marks the return of four series: “Locked Up Abroad” (June 30), “Dangerous Encounters” (July 30), long-running doc series “Explorer” (Aug. 10) and “Alaska State Troopers” (September).
