SINKING CITIES: London

 

See firsthand why London’s Thames Barrier is no longer enough to keep the city safe from rising tides. The system has worked for decades, but due to increased environmental challenges, its location on a flood plain and heavy urbanization, London must now explore both low-tech fixes and some of the most advanced engineering solutions in the world.

MAGICAL LAND OF OZ
Ocean

 

In this episode we see why marine species are drawn to the coasts of Australia and discover that the country’s three surrounding oceans – the Southern Sea, the Pacific and The Indian Ocean create a unique environment for ocean voyagers of all types. In the clean waters of Pearson Island off South Australia Sealions, once a rare sight are now protected from hunting and are thriving. Meanwhile in the shallows of Spencer Gulf, June is the time for a midwinter gathering of spectacularly colourful giant cuttlefish who battle for mates. The cold Southern Ocean also brings humpback whales from Antarctica to give birth and triggers the breath-taking spectacle of thousands of Australian spider crabs, the largest crustaceans in the world, congregating under the piers of Port Philip Bay to moult. It’s a grisly time as the first to reveal their soft shells are cannibalised by their neighbours. Still, there’s safety in numbers as bigger predators, smooth stingrays, sweep over the congregation sucking them from the seabed. A hundred miles up the coast from Sydney, Cabbage Tree Island is home to one of only two breeding colonies of Gould’s petrel in the world. Chicks must find their way across rocky ground, scale the vertical trunks of giant cabbage tree palms and overcome their vicious spines in order to capture the breeze to become airborne. They will spend the next five to six years at sea. Off the west coast the Lacepede Islands are bathed in the warm currents of the Indian Ocean. 18,000 pairs of brown boobies build makeshift nests here whilst further south Shark Bay lives up to its ominous name as tiger sharks sweep in to prey on a whale carcass.

 

 

 

NOVA
Lethal Seas

 

Marine scientists across the world are hunting for clues to one of the greatest environmental catastrophes facing our planet today: ocean acidification. For years we’ve known the ocean absorbs about a quarter of the carbon dioxide in Earth’s atmosphere. But as carbon emissions continue to rise, seawater chemistry is changing, and the ocean’s acidity is increasing. As a result, the skeletons and shells of marine creatures that form the foundation of the web of life are dissolving. Follow scientists who are seeking solutions and making breakthrough discoveries, including a unique coral garden in Papua New Guinea that offers a glimpse of what the seas could be like in a half-century.

 

 

 

INSIGHTS ON PBS HAWAIʻI
Ala Wai Flood Control Project

 

Plans to prevent massive flooding in Waikīkī have been in the works for years, as worries mount over the threat of a major storm causing the Ala Wai Canal to overflow. Drawn up by the U.S. Army Corps of Engineers, the Ala Wai Flood Control Project would take private residential land along the canal for flood mitigation. Property owners object and say there wasn’t enough opportunity for public input. What do you think?

NOVA
Mystery of Easter Island

NOVA Mystery of Easter Island

 

A remote, bleak speck of rock in the Pacific, Easter Island, or Rapa Nui, has mystified the world ever since the first Europeans arrived in 1722. How and why did the ancient islanders build and move nearly 900 giant statues, or moai, weighing as much as 86 tons each? And how did they transform a presumed paradise into a treeless wasteland, bringing ruin upon their island and themselves? NOVA explores controversial recent claims that challenge decades of previous thinking about the islanders, who have been accused of everything from ecocide to cannibalism. Among the radical new theories is that the islanders used ropes to “walk” the statues upright, like moving a fridge. With the help of an accurate 15-ton replica statue, a NOVA team sets out to test this high-risk, seemingly unlikely theory – serving up plenty of action and surprises in this fresh investigation of one of the ancient world’s most intriguing enigmas.
