Exploring The Earth Under The Sea

Exploring the Earth under the Sea brings to life the world’s largest and longest-lived geological research program, which has been drilling over many decades at many locations deep below the ocean floor to recover continuous cores of sediment and rock. Study of these materials has helped us understand how the Earth works now, how it has worked in the past and how it may work in the future. The cores are a wonderful source of information on the dynamic processes that form and reform the Earth, both beneath the ocean and on land. The results have revealed climate and oceanographic change on different time frames, the history of life in the sea and on land including global mass extinctions, the extraordinary story of the great masses of ‘extremophile’ microbes that live beneath the sea bed, the nature of the giant earthquakes and tsunami generated at the trenches where tectonic plates collide, and the nature of submarine volcanoes and metalliferous deposits. This book outlines the technology and enduring international partnerships that underlie the scientific ocean drilling accomplished by the first phase of IODP, currently involving 23 countries. It highlights the important role of Australian and New Zealand scientists in the program, and the great scientific benefits we have derived from our partnership since joining IODP in 2008. As well as the scientific summaries, there are personal accounts by shipboard scientists of how they found life at sea on two-month expeditions, working 12-hour shifts on a noisy drill ship.

Examines how the discovery of hot springs in 1977 on the ocean floor resulted in major developments in science and technology in the twentieth century.

Hundreds of fascinating facts are waiting to be unearthed in this book from Aleksandra and Daniel Mizielinski, the creative duo behind 'Maps'. Dive below the surface, and find out what happens under the earth and under the water. From early submarines and deep-sea life, to burrowing animals and man-made tunnels - you will never look at the world in the same way again!

In the summer of 1803, Thomas Jefferson sent Meriwether Lewis and William Clark on a journey to establish an American presence in a land of unqualified natural resources and riches. Is it fitting that, on the 200th anniversary of that expedition, the United States, together with international partners, should embark on another journey of exploration in a vastly more extensive region of remarkable potential for discovery. Although the oceans cover more than 70 percent of our planet's surface, much of the ocean has been investigated in only a cursory sense, and many areas have not been investigated at all. Exploration of the Seas assesses the feasibility and potential value of implementing a major, coordinated, international program of ocean exploration and discovery. The study committee surveys national and international ocean programs and strategies for cooperation between governments, institutions, and ocean scientists and explorers, identifying strengths, weaknesses, and gaps in these activities. Based primarily on existing documents, the committee summarizes priority areas for ocean research and exploration and examines existing plans for advancing ocean exploration and knowledge.

A human and global take on a beloved vacation spot. The crash of surf, smell of salted air, wet whorls of sand underfoot. These are the sensations of the beach, that environment that has drawn humans to its life-sustaining shores for millennia. And while the gull's cry and the cove's splendor have remained constant throughout time, our relationship with the beach has been as fluid as the runnels left behind by the tide's turning. The Lure of the Beach is a chronicle of humanity's history with the coast, taking us from the seaside pleasure palaces of Roman elites and the aquatic rituals of medieval pilgrims, to the venues of modern resort towns and beyond. Robert C. Ritchie traces the contours of the material and social economies of the beach throughout time, covering changes in the social status of beach goers, the technology of transport, and the development of fashion (from nudity to Victorianism and back again), as well as the geographic spread of modern beach-going from England to France, across the Mediterranean, and from nineteenth-century America to the world. And as climate change and rising sea levels erode the familiar faces of our coasts, we are poised for a contemporary reckoning with our relationship--and responsibilities--to our beaches and their ecosystems. The Lure of the Beach demonstrates that whether as a commodified pastoral destination, a site of ecological resplendency, or a flashpoint between private ownership and public access, the history of the beach is a human one that deserves to be told now more than ever before.

Pinxian Wang and Qianyu Li The South China Sea (SCS) (Fig. 1. 1) offers a special attraction for Earth scientists world-wide because of its location and its well-preserved hemipelagic sediments. As the largest one of the marginal seas separating Asia from the Paci?c, the largest continent from the largest ocean, the SCS functions as a focal point in land-sea int- actions of the Earth system. Climatically, the SCS is located between the Western Paci?c Warm Pool, the centre of global heating at the sea level, and the Tibetan Plateau, the centre of heating at an altitude of 5,000m. Geomorphologically, the SCS lies to the east of the highest peak on earth, Zhumulangma or Everest in the Himalayas (8,848m elevation) and to the west of the deepest trench in the ocean, Philippine Trench (10,497m water depth) (Wang P. 2004). Biogeographically, the SCS belongs to the so-called “East Indies Triangle” where modern marine and terrestrial biodiversity reaches a global maximum (Briggs 1999). Among the major marginal sea basins from the west Paci?c, the SCS presents some of the best conditions for accumulating complete paleoclimatic records in its hemipelagic deposits. These records are favorable for high-resolution pa- oceanographic studies because of high sedimentation rates and good carbonate preservation. It may not be merely a coincidence that two cores from the southern 14 SCS were among the ?rst several cores in the world ocean used by AMS C dating for high-resolution stratigraphy (Andree et al. 1986; Broecker et al. 1988).

Throughout history, people have always explored new frontiers. Adventure, fame, and scientific discovery have all driven humans to forge into the unknown. This title examines exploration under the sea. Easy-to-read, engaging text takes readers to deep ocean trenches, examines the explorers who journeyed to these strange, fascinating areas, and traces the development of the technology and techniques that made this exploration possible. Well-placed sidebars, vivid photos, helpful maps, and a glossary enhance readers' understanding of the topic. Additional features include a table of contents, a selected bibliography, source notes, and an index, plus a timeline and essential facts.
