Ocean tides rise and fall twice a day, influenced by the gravitational forces of the sun and moon. Studying tides' rhythmic movements helps us understand both the ocean and the cosmos. Astronomer Ben Burress explains how tides work, and QUEST visits Crissy Field in San Francisco to see the oldest continually operating tidal gauge in the Western Hemisphere.

The California Academy of Sciences has the largest collection of biological reference materials west of the Mississippi. Dating back over 100 years, the collection provides a treasure trove of biological information for scientists and researchers studying the natural world. Norman Penny, the Collections Manager of the Entomology Department, gives QUEST a small peek at The Academy’s vast butterfly collection.

The Farallon Islands off the coast of San Francisco are a vital home to many birds and marine mammals. While the forbidding and inhospitable nature of the Farallones may be ideal for wildlife, it also makes this a difficult place for scientists to live and work. QUEST ventures out to these jagged rocks to get a glimpse of daily life on the islands and what it’s like there for the researchers from PRBO Conservation Science.

California Highway One, between Pacifica and Montara, was carved out of the steep coastal cliffs. Plagued by closures due to rockslides and land slippage, this route has earned the nickname "The Devil's Slide." Now two tunnels beneath San Pedro Mountain, each 30-feet wide and 4,200-feet long are being dug to bypass it. QUEST meets the engineers and geologists deep underground to learn how Caltrans is digging this new tunnel.

Pale ghosts that hide amidst their gigantic siblings, only a few dozen Albino redwood trees are known to exist. They are genetic mutants that lack the chlorophyll needed for photosynthesis-- how and why they survive is a scientific mystery. QUEST ventures into the deep canopy of Henry Cowell Redwoods State Park near Felton, California to track down these elusive phantoms of the forest.

Scientists say it's no secret San Francisco Bay is rising, along with all of the earth’s oceans. The reason -- global warming. This rise in sea level will affect everyone who lives, works, or plays near the bay. QUEST asks how high will the Bay rise and when? And what steps can communities take to plan for it?

QUEST journeys back to find out how physicists on the UC Berkeley campus in the 1930s, and at the Stanford Linear Accelerator Center in the 1970s, created "atom smashers" that led to key discoveries about the tiny constituents of the atom and paved the way for the Large Hadron Collider in Switzerland.

Flowing 330 miles from the Sierras to the delta, the San Joaquin River is California’s second longest river. It once boasted one of the state's great salmon runs. But since the construction of Friant Dam near Fresno in the 1940s, most of the San Joaquin's water has been siphoned off to farmland in the Central Valley. Now, after years of lawsuits, a new effort to restore the river is offering hope that fish and farmers can co-exist.

Most of us think ants are just pests. But not Brian Fisher. Known as "The Ant Guy," he's on a mission to show the world just how important and amazing these little creatures are and in the process, catalog all of the world's 30,000 ant species before they become casualties of habitat loss. But he can't do it without our help.

The Channel Islands, Monterey Bay, Gulf of the Farallones and Cordell Bank National Marine Sanctuaries cover more than 9,500 square miles of ocean habitat. While most fishing and shipping are still allowed within sanctuary waters, some activities are now regulated or prohibited. Patrolling such an immense area by boat would take days... but now sanctuary managers are taking to the air in a rugged de Havilland DHC-6 Twin Otter bush plane to get a bird's eye view.
