The world’s oceans cover more than 70 percent of the Earth’s surface. Yet we know more about Mars, millions of miles away, than we do about the waters that supply us with oxygen, food, medicine, and transportation routes. And until a devastating event, like the 2004 Indian Ocean tsunami, reminds us of the oceans’ awesome power, most of us give little thought to what’s often called “the last frontier” on our blue planet.
Hidden Depths, based on the eponymous new ocean atlas (HarperCollins Publishers in collaboration with the National Oceanic and Atmospheric Administration and the Smithsonian Institution, 2007), aims to increase and update our knowledge of our most valuable natural resource. The exhibition features detailed new maps of the oceans, delineating such aspects as the ocean floor, salinity, temperature, and other scientific measurements. Newly created charts examine ocean circulation, ecosystems, and hazards (both natural and manmade), ranging from typhoons and tsunamis to shipwrecks, pollution, and marine debris.

This intense look at oceans will appeal to everyone who agrees that a continued understanding of the ocean world will help achieve, in the words of the atlas editors, “a balanced state of economic development, environmental stewardship, and security.”
