Joan Johnson

Joan Johnson is an TV Associate Producer for QUEST. Joan got her start making science television back in 1998 when she joined the team at Sea Studios in Monterey, working as a researcher and production coordinator on National Geographic Television projects for 4 years. Following that she pursued a career in features and network television down in Los Angeles, working on seven full length feature films, three television shows and several pilots. Joan graduated in 1993 from U.C. Santa Cruz with honors in Biology, and spent several years working as a marine biologist, naturalist and SCUBA guide. Originally from San Francisco, Joan is thrilled to be home and working on QUEST, fulfilling a long-term goal of combining her interests in science and entertainment.

Geothermal Heats Up

Solar and wind power may get the headlines when it comes to renewable energy. But another type of clean power is heating up in the hills just north of Sonoma wine country. The Geysers, the world's largest power-producing geothermal field, has been providing electricity for roughly 850,000 Northern California households, and is set to expand even further.

Into the Deep with Elephant Seals

Thousands of northern elephant seals -- some weighing up to 4,500 pounds -- make an annual migration to breed each winter at Año Nuevo State Reserve, on the San Mateo County coast. Marine biologists are using high-tech tools to explore the secrets of these amazing creatures, which can hold their breath for an hour and dive a mile below the surface.

Cool Critters: The Golden Eagle

Although not as famous as its bald cousin, Golden Eagles are much easier to find in Northern California - one of the largest breeding populations for Golden Eagles is right here in the Mount Diablo valley. Meet one of the largest birds of prey as QUEST visits the Lindsay Wildlife Museum in Walnut Creek, CA.

Profile: Sylvia Earle

She's spent much of the last five decades exploring and protecting the world's oceans. Find out why legendary marine biologist Sylvia Earle thinks that we may only have a few years left to save what she calls "the blue heart of the planet."

Seahorse Sleuths

Seahorses are some of the most enchanting and mysterious creatures in the ocean. They are struggling to survive in threatened habitats around the world, while large-scale trading of seahorses for the traditional Chinese medicine market goes unchecked. Meet the Seahorse Sleuths - local scientists who are working to save them from extinction.

Asteroid Hunters

Everyone knows that eight planets orbit the Sun. But thousands of other objects, including icy comets and football field-sized asteroids, are also zooming around our solar system. And some of them could be on a collision course with Earth. QUEST explores how these Near Earth Objects are being tracked and what scientists are saying should be done to prevent a deadly impact.

Zeppelins Resurrected

In 1935, the USS Macon went down in 1000 feet of water off the coast of Monterey, California. Now, as scientists study the recently-discovered wreckage, dirigibles are returning to the Bay Area. But these aren't the same dirigibles - these are new and improved.
