Wild World Conservation Atlas: Southeastern U.S. Rivers and Streams
From its cool-flowing streams in the Appalachian Mountains to its brackish marshes along the Atlantic and Gulf coasts, this collection of freshwater ecoregions includes a variety of habitats and some of the most species-rich freshwater systems on the planet.
Wild World Conservation Atlas: The Bering Sea
Here in one of the world's richest marine environmentsthe waters between Alaska and Russiapolar bears, walruses, whales, seals, and countless birds thrive. And conservationists are fighting to keep it that way.
Wild World Conservation Atlas: Sulu-Sulawesi Seas
Off the coast of Indonesia, Malaysia, and the Philippines is one of the most diverse marine communities on Earth. This ecoregion is home to nine times as many stony corals as live in the Caribbean Sea and more than twice the number found in the Indian Ocean.
Six of the world's seven species of sea turtles can be found here, along with huge whale sharks, massive manta rays, and an amazing abundance of fish species.
Sustainable Seas Expeditions
The Sustainable Seas Expeditions are a pathbreaking partnership between the National Geographic Society and the U.S. National Oceanic and Atmospheric Administration (NOAA) to explore the United States' last frontier: the ocean. The five-year program will investigate, conduct research in, and promote the 12 U.S. National Marine Sanctuaries, which range in size from a tiny bay in far-off American Samoa to a 5,328-square-mile (13,800-square-kilometer) expanse of ocean off the California coast.
Monterey Bay @ Nationalgeographic.com
Embraced by some of northern California's most beautiful shoreline, Monterey Bay National Marine Sanctuary is one of the largest protected marine areas in the world. Millions of visitors are drawn to the otters, harbor seals, and birds that splash along its beachesbut it is the sanctuary's blue expanse of water that teems with an unsurpassed explosion of life.
EarthPulse: Great Barrier Reef
Rising off northeastern Australia, the Great Barrier Reef is actually more than 2,800 coral reefs. Thriving in the clear, shallow coastal water of tropical seas, coral reefs boast a diversity of species rivaled only by that of tropical rain forests. And like rain forests, reefs haves declined drastically due to human actionsa fact that makes the relative purity of the well-protected Great Barrier all the more vivid.
Pulse of the Planet
Pulse of the Planet: Amphibian SuiteHudson Valley, New York
Since the 1980s there has been concern about the health of amphibian populations worldwide. Their numbers have been declining, and people have been finding deformed frogs with missing, extra, or mis-shapen limbs. One theory suggests that pollution is the culprit, but some of the declines have happened in unpolluted areas. And scientists aren't even sure if the decline in population and the physiological problems are related.
