Discovering The Ocean From Space

This book offers a survey of the contribution of satellite data to the study of the ocean, focusing on the special insights that only satellite data can bring to oceanography. Topics range from ocean waves to ocean biology, spanning scales from basins to estuaries. Some chapters cover applications to pure research while others show how satellite data can be used operationally for tasks such as pollution monitoring or oil-spill detection.

This book covers the fundamental principles of measuring oceans from space, and also contains state-of-the-art developments in data analysis and interpretation and in sensors. Completely new will be material covering advances in oceanography that have grown out of remote sensing, including some of the global applications of the data. The variety of applications of remotely sensed data to ocean science has grown significantly and new areas of science are emerging to exploit the gobal datasets being recovered by satellites, particularly in relation to climate and climate change, basin-scale, air-sea interaction processes (e.g. El Nino) and the modelling, forecasting and prediction of the ocean.

In the last 25 years, planetary science experienced a revolution, as vast oceans of liquid water have been discovered within the heart of the icy moons of our Solar System. These subsurface oceans lie hidden under thick layers of ice. We call them ocean worlds. Some of these icy moons, such as Ganymede, may hold two to three times more liquid water than all the water present on Earth, while others, such as Enceladus and Europa, are thought by astrobiologists to be our best hope of finding extraterrestrial life. In this book, we will explore and compare a variety of Solar System ocean worlds, meeting in the process 22 of the most intriguing objects, from the giant asteroid Ceres to the enigmatic, distant Sedna. In doing so, we will also encounter the multiple spacecraft that brought back most of what we know of these worlds (Pioneers, Voyagers, Cassini-Huygens, etc.), as well as the latest scientific research on this new topic. We will also entertain the possibility of life on each of these ocean worlds by assessing their habitability, as ultimately, these ocean worlds might hold the key to answering the fundamental questions in life: How did life appear? Where do we come from? Is there life out there? With the contributions of leading planetary scientists from NASA, ESA, and other institutions, this book aims to be the go-to reference for anyone wanting to know more about this fascinating topic.

Despite the fact that the vast majority of the earth’s surface is made up of oceans, there has been surprisingly little work by geographers which critically examines the ocean-space and our knowledge and perceptions of it. This book employs a broad conceptual and methodological framework to analyse specific events that have contributed to the production of geographical knowledge about the ocean. These include, but are not limited to, Christopher Columbus’ first transatlantic journey, the mapping of nonexistent islands, the establishment of transoceanic trade routes, the discovery of largescale water movements, the HMS Challenger expedition, the search for the elusive Terra Australis Incognita, the formulation of the theory of continental drift and the mapping of the seabed. Using a combination of original, empirical (archival, material and cartographic), and theoretical sources, this book uniquely brings together fascinating narratives throughout history to produce a representation and mapping of geographical oceanic knowledge. It questions how we know what we know about the oceans and how this knowledge is represented and mapped. The book then uses this representation and mapping as a way to coherently trace the evolution of oceanic spatial awareness. In recent years, particularly in historical geography, discovering and knowing the ocean-space has been a completely separate enterprise from discovering and colonising the lands beyond it. There has been such focus on studying colonised lands, yet the oceans between them have been neglected. This book gives the geographical ocean a voice to be acknowledged as a space where history, geography and indeed historical geography took place.

“[An] amiable, in-depth examination of the most critical era for the development of modern oceanography” (Publishers Weekly). 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. “Rozwadowski greatly expands our own understanding, all while telling a story that is original, wide-ranging, and illuminating.” —Margaret Deacon, Southampton Oceanography Centre, author of Science and the Sea: The Origins of Oceanography “Required reading for anyone wanting to understand how the oceans have come to play the role that they do in Western knowledge.” —Eric L. Mills, Dalhousie University and author of Biological Oceanography: An Early History, 1870-1960 “Chronicles the birth of deep-sea oceanography, from early observations by Benjamin Franklin to the voyage of HMS Challenger in the 1870s. [Rozwadowski] weaves a rich narrative from the world of renowned as well as lesser-known oceanographers.” —Nature

Invisible as the seas and oceans may be for so many of us, life as we know it is almost always connected to, and constituted by, activities and occurrences that take place in, on and under our oceans. The Routledge Handbook of Ocean Space provides a first port of call for scholars engaging in the ‘oceanic turn’ in the social sciences, offering a comprehensive summary of existing trends in making sense of our water worlds, alongside new, agenda-setting insights into the relationships between society and the ‘seas around us’. Accordingly, this ambitious text not only attends to a growing interest in our oceans, past and present; it is also situated in a broader spatial turn across the social sciences that seeks to account for how space and place are imbricated in socio-cultural and political life. Through six clearly structured and wide-ranging sections, The Routledge Handbook of Ocean Space examines and interrogates how the oceans are environmental, historical, social, cultural, political, legal and economic spaces, and also zones where national and international security comes into question. With a foreword and introduction authored by some of the leading scholars researching and writing about ocean spaces, alongside 31 further, carefully crafted chapters from established as well as early career academics, this book provides both an accessible guide to the subject and a cutting-edge collection of critical ideas and questions shaping the social sciences today. This handbook brings together the key debates defining the ‘field’ in one volume, appealing to a wide, cross-disciplinary social science and humanities audience. Moreover, drawing on a range of international examples, from a global collective of authors, this book promises to be the benchmark publication for those interested in ocean spaces, past and present. Indeed, as the seas and oceans continue to capture world-wide attention, and the social sciences continue their seaward ‘turn’, The Routledge Handbook of Ocean Space will provide an invaluable resource that reveals how our world is a water world.

Inside the epic quest to find life on the water-rich moons at the outer reaches of the solar system Where is the best place to find life beyond Earth? We often look to Mars as the most promising site in our solar system, but recent scientific missions have revealed that some of the most habitable real estate may actually lie farther away. Beneath the frozen crusts of several of the small, ice-covered moons of Jupiter and Saturn lurk vast oceans that may have existed for as long as Earth, and together may contain more than fifty times its total volume of liquid water. Could there be organisms living in their depths? Alien Oceans reveals the science behind the thrilling quest to find out. Kevin Peter Hand is one of today's leading NASA scientists, and his pioneering research has taken him on expeditions around the world. In this captivating account of scientific discovery, he brings together insights from planetary science, biology, and the adventures of scientists like himself to explain how we know that oceans exist within moons of the outer solar system, like Europa, Titan, and Enceladus. He shows how the exploration of Earth's oceans is informing our understanding of the potential habitability of these icy moons, and draws lessons from what we have learned about the origins of life on our own planet to consider how life could arise on these distant worlds. Alien Oceans describes what lies ahead in our search for life in our solar system and beyond, setting the stage for the transformative discoveries that may await us.
