Wicked Tuna: Outer Banks Showdown (9 p.m., National Geographic)

Season 9 debuts tonight after a year-long hiatus with back to back episodes. The top captains from Gloucester return to the Outer Banks of North Carolina to battle it out against the best bluefin tuna fishermen in the South.

▪ In the first episode, titled “Northern Invasion,” the Northern champions Hot Tuna, FV-Tuna.com, and Pinwheel return to face their Southern rivals Fishin’ Frenzy, Little Shell, and Reel E’ Bugging in an effort to prove who is the best of the best.

According to National Geographic, the premiere episode includes an intense scene in which captains on the Fishin’ Frenzy and Reel E’ Bugging boats race to the dock to try to lock in the first catch of the season.

▪ A second episode, titled “Danger Zone,” airs immediately after at 10. In that episode, “the Battle of Champions is underway, and Reel E’ Bugging takes a huge gamble to get ahead when they try to cross the bar in dangerous conditions. Meanwhile, the Northern fleet attempts to bounce back from their slow start using every tactic they can think of to close the gap with the Southern boats.”

Patagonia: Life on the Edge of the World (9 p.m., CNN)

Tonight we get the second installment in a six-part docuseries narrated by Chilean-born Pedro Pascal exploring the wonders of Patagonia in South America, one of the last untouched places on earth.

From CNN: “Stretching for more than a thousand miles through Chile and Argentina, Patagonia is a place unlike any other: wild, isolated, pristine, and unexplored. The region’s iconic wildlife – pumas, penguins, condors, and killer whales – thrive in a rich diversity of habitats, and species new to science – insect, bird, and even mammal – are discovered here each year.”

The description for Episode 2, titled “Fjordlands,” reads: “Along Patagonia’s Pacific coast are deep, sheltered fjords. In summer, the nutrient-rich waters are in high demand from both animals and people, which threatens natural balance.”

The documentary series takes audiences across Patagonia’s diverse and spectacular landscapes, traveling along its coastline from wind-blown deserts to pristine fjordlands, from deep inside its magical, ancient forests up to the high peaks of the Andes. It showcases the wildlife, the scientists who study it, and the people of the region who have evolved to live in these varied habitats.

“Patagonia: Life on the Edge” was filmed over the course of one year, using state-of-the-art cameras and help from local experts granting unprecedented access.

The series will regularly air on Sundays at 9 p.m. and will stream live for pay TV subscribers via CNN.com and CNN OTT and mobile apps under “TV Channels” or CNNgo where available. The series will also be available On Demand the day after the broadcast premiere to pay TV subscribers via CNN.com, CNN apps, and Cable Operator Platforms.
