For centuries, humans ignored sound in the “silent world” of the ocean, assuming that what we couldn’t perceive, didn’t exist. But we couldn’t have been more wrong. Marine scientists now have the technology to record and study the complex interplay of the myriad sounds in the sea. Finally, we can trace how sounds travel with the currents, bounce from the seafloor and surface, bend with the temperature and even saltiness; how sounds help marine life survive; and how human noise can transform entire marine ecosystems.

Acute natural perceptivity and a profound knowledge of the relationships to be found in nature combine here in vivid evocations of the sights, the sounds, the vast stillnesses, and the events of the wilderness as the seasons succeed each other. But Mr. Olson is not content merely to "describe"; he probes for meanings that will lead the listener to a different and more revealing way of looking at the out-of-doors and to a deeper sense of its eternal values.

Black Dragon River is a personal journey down one of Asia's great rivers. The world's ninth largest river, the Amur serves as a large part of the border between Russia and China. As a crossroads for the great empires of Asia, this area offers journalist Dominic Ziegler a lens with which to examine the societies at Europe's only borderland with East Asia.

Murray Morgan's classic history of the Olympic Peninsula, originally published in 1955, evokes a remote American wilderness "as large as the state of Massachusetts, more rugged than the Rockies, its lowlands blanketed by a cool jungle of fir and pine and cedar, its peaks bearing hundreds of miles of living ice that gave rise to swift rivers alive with giant salmon."

Fights over the Green River's water, and what's going to happen to it in the future, are longstanding, intractable, and only getting worse as the West gets hotter and drier, and more people depend on the river with each passing year. As a former raft guide and an environmental reporter, Heather Hansman knew these fights were happening, but she felt driven to see them from a different perspective - from the river itself.

A Silent Spring for our era, this eloquent, urgent, fascinating book reveals how just 50 years of swift and dangerous oceanic change threatens the very existence of life on Earth. Legendary marine scientist Sylvia Earle portrays a planet teetering on the brink of irreversible environmental crisis.

The magnificent Danube both cuts across and connects Central Europe, flowing through and alongside 10 countries: Romania, Ukraine, Moldova, Bulgaria, Serbia, Croatia, Hungary, Slovakia, Austria, and Germany. Travelling its full length from east to west, against the river's flow, Nick Thorpe embarks on an inspiring yearlong journey that leads to a new perspective on Europe today. Thorpe's account is personal, conversational, funny, immediate, and uniquely observant - everything one expects in the best travel writing.

Few books have captured the haunting world of music and rivers and of the sport they provide as well as A River Never Sleeps. Roderick L. Haig-Brown writes of fishing not just as a sport, but also as an art. He knows moving water and the life within it - its subtlest mysteries and perpetual delights. He is a man who knows fish lore as few people ever will, and the legends and history of a great sport. Month by month, he takes you from river to river, down at last to the saltwater and the sea.

For centuries, mariners have spun tales of gargantuan waves, 100-feet high or taller. Until recently scientists dis​missed these stories - waves that high would seem to violate the laws of physics. But in the past few decades, as a startling number of ships vanished and new evidence has emerged, oceanographers realized something scary was brewing in the planet’s waters. They found their proof in February 2000, when a British research vessel was trapped in a vortex of impossibly mammoth waves in the North Sea - including several that approached 100 feet.

Rivers have acted as cradles for civilization and agents of disaster; a river may be a barrier or a highway, it can support trade and sediment, culture and conflict. This Very Short Introduction is a celebration of rivers in all their diversity. Geographer Nick Middleton covers a wide and eclectic range of river-based themes, from physical geography to mythology, to industrial history and literary criticism.

On the Alaska Peninsula, where exceptional landscapes are commonplace, a small river attracts attention far beyond its scale. Each year, from summer to early fall, brown bears and salmon gather at Brooks River to create one of North America's greatest wildlife spectacles. As the salmon leap from the cascade, dozens of bears are there to catch them, and thousands of people come to watch in person or on the National Park Service's popular Brooks Falls Bearcam. The Bears of Brooks Falls tells the story of this region and the bears that made it famous.

The world of wildlife is full of surprising and magical quirks - and Sue Perkins - comedian, broadcaster and Just a Minute host - is on a mission to discover them all. In this fantastic series, recorded at ZSL London Zoo and the Eden Project, she's joined by a diverse group of comedians and natural history experts for some entertaining sessions of 'Show and Tell'.

In The Last Empty Places, bestselling author Peter Stark takes the listener to four of the most remote, wild, and unpopulated areas of the United States outside of Alaska, and mainly not part of protected wilderness: the rivers and forests of Northern Maine; the rugged, unpopulated region of Western Pennsylvania, that lies only a short distance from the East's big cities; the haunting canyons of Central New Mexico; and the vast, arid basins of Southeast Oregon.

Bright Rivers chronicles the angling passions and frustrations of one of fly-fishing's greatest men of letters. A city dweller trapped in the complexities of modern life, Nick Lyons has always found solace in his pilgrimages to great rivers. It is there that he fishes for trout, and in Bright Rivers, Lyons recounts the sometimes moving, sometimes hilarious experiences of his expeditions to the Delaware, Beaverkill, Madison, Big Hole, and Yellowstone rivers, sharing reminiscences of trout taken, released, and sometimes lost.

One of the nation's most popular presenters, Sir David examines 40 marvels of the natural world from his extraordinary and pioneering experiences. What was Sir David's first pet? Which animal would he most like to be? How did he track down a giant earthworm? Why does he respect rats? And what did he do when confronted by a 10-foot-long reptile? His enthusiasm is as infectious as ever and conveys a unique fascination on topics as diverse as the sloth, monstrous flowers, the platypus, dragons, the fire salamander, the coelacanth, the dodo, bird's-nest soup and the large blue butterfly.

This classic is an essential handbook for anyone who studies, surfs, protects, or is fascinated by the ocean, with a wealth of information based on theory and statistics, but also anecdotal observation and personal experience. It brought to the general public understanding of the awesome and complex power of the waves. This revision from Kim McCoy updates the book's relevance in the time of climate change. One of the most significant effects of global warming will be sea-level rise. What will this mean to waves and beaches, and what effects are we already seeing?

The grizzly is one of North America's few remaining large predators. Their range is diminished, but they're spreading across the West again. Descending into valleys where once they were king, bears find the landscape they'd known for eons utterly changed by the new most dominant animal: humans. In searing detail, award-winning writer, Montana rancher, and conservationist Bryce Andrews tells us about one such grizzly. Millie is a typical mother: strong, cunning, fiercely protective of her cubs. But raising those cubs becomes ever harder as the climate warms and people crowd the valleys.

In The Big Melt, Rolling Stone contributing editor and leading environmental journalist Jeff Goodell takes the listener up close and personal to one of the world’s most remote locations—Western Antarctica—and to the foot of the staggeringly important Thwaites Glacier.

Coral reefs are a microcosm of our planet: extraordinarily diverse, deeply interconnected, and full of wonders. When they’re thriving, these fairy gardens hidden beneath the ocean’s surface burst with color and life. They sustain bountiful ecosystems and protect vulnerable coasts. Corals themselves are evolutionary marvels that build elaborate limestone formations from their collective skeletons, broker symbiotic relationships with algae, and manufacture their own fluorescent sunblock.

If you live on a rapidly changing planet, you'd be wise to learn how it works. The giant old forests on a skinny stretch of land on the far west coast of North America have a lot to say about living in a twitchy world.
