Lapita comprises an archaeological horizon that is fundamental to the understanding of human colonisation and settlement of the Pacific as it is associated with the arrival of the common ancestors of the Polynesians and many Austronesian-speaking Melanesians more than 3000 years ago. While Lapita archaeology has captured the imagination and sustained the focus of archaeologists for more than 50 years, more recent discoveries have inspired renewed interpretations and assessments. Oceanic Explorations reports on a number of these latest discoveries and includes papers which reassess the Lapita phenomenon in light of this new data. They reflect on a broad range of interrelated themes including Lapita chronology, patterns of settlement, migration, interaction and exchange, ritual behaviour, sampling strategies and ceramic analyses, all of which relate to aspects highlighting both advances and continuing impediments associated with Lapita research.

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. Aligned to Common Core Standards and correlated to state standards. Essential Library is an imprint of Abdo Publishing, a division of ABDO.

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.

This book focuses on how marine systems respond to natural and anthropogenic perturbations (ENSO, overfishing, pollution, tourism, invasive species, climate-change). Authors explain in their chapters how this information can guide management and conservation actions to help orient and better manage, restore and sustain the ecosystems services and goods that are derived from the ocean, while considering the complex issues that affect the delicate nature of the Islands. This book will contribute to a new understanding of the Galapagos Islands and marine ecosystems.​

This second edition provides extensive information on the attributes of the Natural Gas Hydrate (NGH) system, highlighting opportunities for the innovative use and modification of existing technologies, as well as new approaches and technologies that have the potential to dramatically lower the cost of NGH exploration and production. Above all, the book compares the physical, environmental, and commercial aspects of the NGH system with those of other gas resources. It subsequently argues and demonstrates that natural gas can provide the least expensive energy during the transition to, and possibly within, a renewable energy future, and that NGH poses the lowest environmental risk of all gas resources. Intended as a non-mathematical, descriptive text that should be understandable to non-specialists as well as to engineers concerned with the physical characteristics of NGH reservoirs and their production, the book is written for readers at the university graduate level. It offers a valuable reference guide for environmentalists and the energy community, and includes discussions that will be of great interest to energy industry professionals, legislators, administrators, regulators, and all those concerned with energy options and their respective advantages and disadvantages.

By the middle of the nineteenth century, as scientists explored the frontiers of polar regions and the atmosphere, the ocean remained silent and inaccessible. The history of how this changed—of how the depths became a scientific passion and a cultural obsession, an engineering challenge and a political attraction—is the story that unfolds in Fathoming the Ocean. In a history at once scientific and cultural, Helen Rozwadowski shows us how the Western imagination awoke to the ocean's possibilities—in maritime novels, in the popular hobby of marine biology, in the youthful sport of yachting, and in the laying of a trans-Atlantic telegraph cable. The ocean emerged as important new territory, and scientific interests intersected with those of merchant-industrialists and politicians. Rozwadowski documents the popular crazes that coincided with these interests—from children's sailor suits to the home aquarium and the surge in ocean travel. She describes how, beginning in the 1860s, oceanography moved from yachts onto the decks of oceangoing vessels, and landlubber naturalists found themselves navigating the routines of a working ship's physical and social structures. Fathoming the Ocean offers a rare and engaging look into our fascination with the deep sea and into the origins of oceanography—origins still visible in a science that focuses the efforts of physicists, chemists, geologists, biologists, and engineers on the common enterprise of understanding a vast, three-dimensional, alien space.
