Sunken Ship Rescue

 

NOVA follows the epic operation to secure, raise and salvage the Costa Concordia cruise ship, which ran aground and capsized off the coast of Italy on January 13, 2012, killing 32 people. The wreck stretches the length of three football fields, weighs 45,000 tons and lay half submerged on the site of a protected reef, with a 160-foot-long hole in its hull. Moving it from its precarious perch on the edge of an underwater cliff is a huge technical and logistical challenge. NOVA joins a team of more than 500 divers and engineers working around the clock as they attempt the biggest ship recovery project in history.

Sinkholes: Buried Alive

 

In Tampa, Florida, in February 2013, a giant hole opened up under the bedroom floor of Jeffrey Bush, swallowing the 36-year-old as he slept. His body was never found. Bush was a victim of a sinkhole – a growing worldwide hazard that lurks wherever limestone and other water-soluble rocks underpin the soil. When carbon dioxide in the air dissolves in rainwater, it forms a weak acid that attacks the soft rocks, riddling them with holes. Sinkholes can occur gradually when the surface subsides into bowl-shaped depressions or suddenly, when the ground gives way – often catastrophically.

Killer Landslides

 

In less than two minutes in March of this year, a one-square-mile field of debris slammed into the Washington state community of Oso, killing 41 and destroying nearly 50 homes. Drawing on analyses of other recent landslides around the world, geologists are investigating what triggered the deadliest U.S. landslide in decades and whether climate change is increasing the risk of similar disasters around the globe.

Nazi Attack on America

NOVA Nazi Attack on America

 

Long before 9/11, a little-known attack from the ocean depths struck our shores, lasting three-and-a-half years and claiming 5,000 lives. Now, famed undersea explorer Bob Ballard, discoverer of the Titanic, investigates the wreck of one of the attack craft, a German submarine that lies at the bottom of the gulf just a few miles off New Orleans.

 

U-166 was part of Operation Drumbeat, a highly successful U-boat operation that caught East Coast cities and shipping almost completely unprepared. With state-of-the-art survey gear, Ballard probes the wreck and unravels a dramatic mystery in the official story of the sub’s sinking.

Bombing Hitler’s Supergun

 

Growing desperate in 1943, Hitler hatches a diabolical weapon: a bank of “superguns” housed in a massive underground complex in Nazi occupied northern France. Together the guns would be able to shoot 600 high explosive shells 100 miles into downtown London every hour. Join NOVA as engineers, archaeologists and WWII historians investigate this fearsome weapon.

Bigger Than T.rex

 

Almost a century ago, paleontologists found the first tantalizing hints of a monster even bigger than Tyrannosaurus rex, perhaps the largest predator ever to walk the Earth: spectacular fossil bones from a dinosaur dubbed Spinosaurus. But the fossils were completely destroyed during a World War II Allied bombing raid, leaving only drawings, lots of questions, and a mystery: What was Spinosaurus? Now, the discovery of new bones in a Moroccan cliff face is reopening the investigation into this epic beast. What did it feed on and how? Why did it grow so big?

 

We follow the paleontologists who are reconstructing this terrifying carnivore piece by piece, revealing a 53-foot-long behemoth with a huge dorsal sail, enormous, scimitar-like claws and massive jaws, tapered toward the front like a crocodile, hosting an army of teeth. Bringing together experts in paleontology, geology, climatology and paleobotany, this NOVA/National Geographic special brings to life the lost world over which Spinosaurus reigned more than 65 million years ago.

Vaccines: Calling the Shots

 

Diseases that were largely eradicated in the United States a generation ago – including whooping cough, measles and mumps – are returning, in part because nervous parents are skipping their children’s shots. Go around the world to track epidemics, explore the science behind vaccinations and discover the risks of opting out.
