It turned up in a North Dakota wheat field: a triangle, like a shark's fin, sticking up from the black loam. Tom Lasker did what any farmer would have done. He dug it up. And discovered a boat, made of a fiberglass-like material with an utterly impossible atomic number. What it was doing buried under a dozen feet of prairie soil two thousand miles from any ocean, no one knew. True, Tom Lasker's wheat field had once been on the shoreline of a great inland sea, but that was a long time ago -- ten thousand years ago. A return to science fiction on a grand scale, reminiscent of the best of Heinlein, Simak, and Clarke, Ancient Shores is the most ambitious and exciting SF triumph of the decade, a bold speculative adventure that does not shrink from the big questions -- and the big answers.
Oceans were long thought to exist in all corners of the Solar System, from carbonated seas percolating beneath the clouds of Venus to features on the Moon's surface given names such as "the Bay of Rainbows” and the "Ocean of Storms." With the advent of modern telescopes and spacecraft exploration these ancient concepts of planetary seas have, for the most part, evaporated. But they have been replaced by the reality of something even more exotic. For example, although it is still uncertain whether Mars ever had actual oceans, it now seems that a web of waterways did indeed at one time spread across its surface. The "water" in many places in our Solar System is a poisoned brew mixed with ammonia or methane. Even that found on Jupiter's watery satellite Europa is believed similar to battery acid. Beyond the Galilean satellites may lie even more "alien oceans." Saturn's planet-sized moon Titan seems to be subject to methane or ethane rainfall. This creates methane pools that, in turn, become vast lakes and, perhaps, seasonal oceans. Titan has other seas in a sense, as large shifting areas of sand covering vast plains have been discovered. Mars also has these sand seas, and Venus may as well, along with oceans of frozen lava. Do super-chilled concoctions of ammonia, liquid nitrogen, and water percolate beneath the surfaces of Enceladus and Triton? For now we can only guess at the possibilities. 'Alien Seas' serves up part history, part current research, and part theory as it offers a rich buffet of "seas" on other worlds. It is organized by location and by the material of which various oceans consist, with guest authors penning specific chapters. Each chapter features new original art depicting alien seas, as well as the latest ground-based and spacecraft images. Original diagrams presents details of planetary oceans and related processes.
A variety of themes is explored in this anthology of the best contemporary Australian fantasy writing. From Isobelle Carmody's tragic romantic style and Terry Dowling's complex and technical world to Damien Broderick's vision of multiple worlds and Carmel Bird's "genetic unconscious deciding factor," the writers included tell enthralling stories strengthened by imagination that extends beyond the boundaries of the concrete world.
Nebula and Hugo award-winning author David Brin continues his bestselling Uplift series in this second novel of a bold new trilogy. Imaginative, inventive, and filled with Brin's trademark mix of adventure, passion, and wit, Infinity's Shore carries us further than ever before into the heart of the most beloved and extraordinary science fiction sagas ever written. For the fugitive settlers of Jijo, it is truly the beginning of the end. As starships fill the skies, the threat of genocide hangs over the planet that once peacefully sheltered six bands of sapient beings. Now the human settlers of Jijo and their alien neighbors must make heroic--and terrifying--choices. A scientist must rally believers for a cause he never shared. And four youngsters find that what started as a simple adventure--imitating exploits in Earthling books by Verne and Twain--leads them to the dark abyss of mystery. Meanwhile, the Streaker, with her fugitive dolphin crew, arrives at last on Jijo in a desperate search for refuge. Yet what the crew finds instead is a secret hidden since the galaxies first spawned intelligence--a secret that could mean salvation for the planet and its inhabitants...or their ultimate annihilation.
Now in paperback, returning to the universe of New York Times Notable book This Alien Shore comes a new space opera from an acknowledged master of science fiction. When deep-space travel altered the genes of the first interstellar colonists, Earth abandoned them. But some of the colonies survived, and a new civilization of mental and physical “Variants” has been established, centered around clusters of space stations known as the outworlds. Now the unthinkable has happened: a suicide assault has destroyed the life support system of a major waystation. All that is known about the young men responsible is that in their last living moments they were receiving messages from an uninhabited sector of space, and were playing a virtual reality game. Two unlikely allies have joined forces to investigate the incident: Ru Gaya, a mercenary explorer with a taste for high risk ventures, and game designer Micah Bello, who must find the parties responsible for the attack in order to clear his name. From the corridors of a derelict station lost to madness to an outlaw stronghold in the depths of uncharted space, the two now follow the trail of an enemy who can twist human minds to his purpose, and whose plans could bring about the collapse of outworld civilization.
This is an introduction to the study of marine rocky shores in the temperate zone. It is designed to encourage students and others to couple enormous intellectual rewards with the pleasure of working in some of the last easily accessible but relatively unspoilt places, and can be used as abasis for field courses, project work, or for lectures. Centred in North-West Europe, but using examples from all over the world, the book begins by considering the physical factors that characterize the habitat - primarily tides and waves - and goes on to assess how they influence the organisms that live within it. It describes how the behaviour andphysiology of individuals belonging to the major groups - algae, grazers, suspension feeders, and predators - are affected by their habitat, how their communities are structured, and discusses theories of community organization. For field courses, it suggests experiments and observations that can becarried out on the shore or in nearby laboratories. Finally, problems of pollution and conservation are considered in the context of their effects upon biodiversity.
