In our "wireless" world it is easy to take the importance of the undersea cable systems for granted, but the stakes of their successful operation are huge, as they are responsible for carrying almost all transoceanic Internet traffic. In The Undersea Network Nicole Starosielski follows these cables from the ocean depths to their landing zones on the sandy beaches of the South Pacific, bringing them to the surface of media scholarship and making visible the materiality of the wired network. In doing so, she charts the cable network's cultural, historical, geographic and environmental dimensions. Starosielski argues that the environments the cables occupy are historical and political realms, where the network and the connections it enables are made possible by the deliberate negotiation and manipulation of technology, culture, politics and geography. Accompanying the book is an interactive digital mapping project, where readers can trace cable routes, view photographs and archival materials, and read stories about the island cable hubs.

Description This book provides a detailed overview of the evolution of undersea communications systems, with emphasis on the most recent breakthroughs of optical submarine cable technologies based upon Wavelength Division Multiplexing, optical amplification, new-generation optical fibers, and high-speed digital electronics. The role played by submarine-communication systems in the development of high-speed networks and associated market demands for multiplying Internet and broadband services is also covered. Importance of This Topic This book will fill the gap between highly specialized papers from large international conferences and broad-audience technology review updates. The book provides a full overview of the evolution in the field and conveys the dimension of the large undersea projects. In addition, the book uncovers the myths surrounding marine operations and installations in that domain, which have remained known so far to only very few specialists.

There are many things and services in our everyday life that we take for granted, and telecommunications is one of them. We surf the internet, send emails to friends and colleagues abroad, talk to family members in foreign countries over the phone, book airline seats and make banking transactions without actually realizing and appreciating the sophisticated technology that enables us to do so. This report covers the history and nature of cables, their special status in international law, their interaction with the environment and other ocean users and, finally, the challenges of the future. It is an evidence-based synopsis that aims to improve the quality and availability of information to enhance understanding and cooperation between all stakeholders. UNEP-WCMC in collaboration with the International Cable Protection Committee and UNEP has prepared this new report to provide an objective, factual description of the sub-marine cable industry and the interaction of submarine telecommunications (which route 95% of all international communications traffic) with the marine environment. This important report seeks to focus and guide deliberations and decision making on the wise conservation and protection of the oceans in concert with their sustainable management and use.

Submarine Optical Cable Engineering presents a summary and exposition from authors engaged in the submarine optical cable engineering field. It systematically discusses the theory and practice of engineering site selection, route survey, laying construction, system maintenance, and safety in operation and information management, all topics relating to the long-term development and progress of science and technology. As there are now more than 230 extant systems, with a total length of more than one million kilometers, this book compiles the wealth of experience that has accumulated regarding their construction stemming from the first inter ocean submarine cable system (TAT-8) built in 1988. Describes and summarizes the theory and practice of submarine optical cable engineering site selection, route survey, laying construction, system maintenance, safety in operation and information management Presents analysis derived from active engagement in the construction of submarine optical cables engineering taken from decades of experience Embodies the theory of marine science and engineering practice, combining multidisciplinary and interdisciplinary combination of knowledge and international perspective on the characteristics and the discussion of theory, technology and methods Introduces the international submarine cable protection organizations, relevant law and the law of the sea

Underwater wireless sensor networks (UWSN) are envisioned as an aquatic medium for a variety of applications including oceanographic data collection, disaster management or prevention, assisted navigation, attack protection, and pollution monitoring. Similar to terrestrial wireless sensor networks (WSN), UWSNs consist of sensor nodes that collect the information and pass it to a base station; however, researchers have to face many challenges in executing the network in an aquatic medium. Energy-Efficient Underwater Wireless Communications and Networking is a crucial reference source that covers existing and future possibilities of the area as well as the current challenges presented in the implementation of underwater sensor networks. While highlighting topics such as digital signal processing, underwater localization, and acoustic channel modeling, this publication is ideally designed for machine learning experts, IT specialists, government agencies, oceanic engineers, communication experts, researchers, academicians, students, and environmental agencies concerned with optimized data flow in communication network, securing assets, and mitigating security attacks.

In Media Hot and Cold Nicole Starosielski examines the cultural dimensions of temperature to theorize the ways heat and cold can be used as a means of communication, subjugation, and control. Diving into the history of thermal media, from infrared cameras to thermostats to torture sweatboxes, Starosielski explores the many meanings and messages of temperature. During the twentieth century, heat and cold were broadcast through mass thermal media. Today, digital thermal media such as bodily air conditioners offer personalized forms of thermal communication and comfort. Although these new media promise to help mitigate the uneven effects of climate change, Starosielski shows how they can operate as a form of biopower by determining who has the ability to control their own thermal environment. In this way, thermal media can enact thermal violence in ways that reinforce racialized, colonial, gendered, and sexualized hierarchies. By outlining how the control of temperature reveals power relations, Starosielski offers a framework to better understand the dramatic transformations of hot and cold media in the twenty-first century.

The United States faces decisions requiring information about the oceans in vastly expanded scales of time and space and from oceanic sectors not accessible with the suite of tools now used by scientists and engineers. Advances in guidance and control, communications, sensors, and other technologies for undersea vehicles can provide an opportunity to understand the oceans' influence on the energy and chemical balance that sustains humankind and to manage and deliver resources from and beneath the sea. This book assesses the state of undersea vehicle technology and opportunities for vehicle applications in science and industry. It provides guidance about vehicle subsystem development priorities and describes how national research can be focused most effectively.

Nere has never understood why she feels so much more comfortable and confident in water than on land, but everything falls into place when Nere learns that she is one of a group of kids who --unbeknownst to them -- have been genetically altered to survive in the ocean. These products of "The Neptune Project" will be able to build a better future under the sea, safe from the barren country's famine, wars, and harsh laws. But there are some very big problems: no one asked Nere if she wanted to be a science experiment, the other Neptune kids aren't exactly the friendliest bunch, and in order to reach the safe haven of the Neptune colony, Nere and her fellow mutates must swim through hundreds of miles of dangerous waters, relying only on their wits, dolphins, and each other to evade terrifying undersea creatures and a government that will stop at nothing to capture the Neptune kids . . . dead or alive. Fierce battles and daring escapes abound as Nere and her friends race to safety in this action-packed aquatic adventure.
