More than 75 percent of the globe is covered by the oceans. It is sometimes difficult to understand why it is called Planet Earth rather than Planet Ocean. Since half the world's human population lives within a stone's throw of an ocean coastline, the oceans' health is increasingly important. Rich with resources and potential--as a source of renewable energy, new drugs, drinking water--for years we...

The geologically ancient Tidewater region of southeastern Virginia and northeastern North Carolina rests precariously atop millions of years of erosion from the nearby Appalachian Mountains. An immense wetland at near sea level, it is host to every conceivable body of fresh water, ranging from brooding swamps and large hidden lakes to sluggish blackwater rivers and brackish sounds (one of which was so large an early explorer thought he had found the Pacific Ocean). In this engaging book, biologist and Tidewater native Roy T. Sawyer delivers an ecohistory of this unique waterland whose...

At the center of Deep Blue Home a penetrating exploration of the ocean as single vast current and of the creatures dependent on it is Whitty s description of the three-dimensional ocean river, far more powerful than the Nile or the Amazon, encircling the globe. It s a watery force connected to the earth s climate control and so to the eventual fate of the human race.

Whitty s thirty-year career as a documentary filmmaker and diver has given her sustained access to the scientists dedicated to the study of an astonishing range of ocean life, from the physiology of extremophile...

Empire to Nation offers a new consideration of the image of the sea in British visual culture during a critical period for both the rise of the visual arts in Britain and the expansion of the nation's imperial power. It argues that maritime imagery was central to cultivating a sense of nationhood in relation to rapidly expanding geographical knowledge and burgeoning imperial ambition. At the same time, the growth of the maritime empire presented new opportunities for artistic enterprise.

Taking as its starting point the year 1768, which marks the foundation of the Royal...

We have long lorded over the ocean. But only recently have we become aware of the myriad life-forms beneath its waves. We now know that this delicate ecosystem is our life-support system; it regulates the earth s temperatures and climate and comprises 99 percent of living space on earth. So when we change the chemistry of the whole ocean system, as we are now, life as we know it is threatened.
In "Seasick, "veteran science journalist Alanna Mitchell dives beneath the surface of the world s oceans to give readers a sense of how this watery realm can be managed and preserved, and with it...
