Presented in an accessible, user-friendly format, this atlas sets out all the major features revealed during one of the largest ever deep-sea mapping campaigns. A unique insight into the morphology of the seabed along the continental margin of the North-East Atlantic, it reveals for the first time many features that have hitherto been hidden beneath the waves. It is organised both thematically and by region, with the sea floor and its biological hotspots – areas of high biodiversity such as seamounts – shown at a resolution not possible before. The atlas presents everything from submarine canyons to coral carbonate mounds, using digital terrain models generated from multibeam data and photographs taken from unmanned deep-water vehicles (ROVs). The full-colour imagery includes digital three-dimensional seabed maps as well as the photographs, with concise text descriptions and topic boxes used to highlight and explain the geological, biological and hydrographical features, in addition to their importance and context in the deep-sea realm. Alongside the wealth of background information and topic boxes on special highlights, extensive on-line resources link the reader to full data sets and GIS locations, while suggestions for further reading point to ongoing research highlights. This is a fascinating resource that will be of use to anyone involved in off-shore and underwater activities, whether scientific or commercial.

The conservation of marine benthic biodiversity is a recognised goal of a number of national and international programs such as the United Nations Convention on Biodiversity (CBD). In order to attain this goal, information is needed about the distribution of life in the ocean so that spatial conservation measures such as marine protected areas (MPAs) can be designed to maximise protection within boundaries of acceptable dimensions. Ideally, a map would be produced that showed the distribution of benthic biodiversity to enable the efficient design of MPAs. The dilemma is that such maps do not exist for most areas and it is not possible at present to predict the spatial distribution of all marine life using the sparse biological information currently available. Knowledge of the geomorphology and biogeography of the seafloor has improved markedly over the past 10 years. Using multibeam sonar, the benthic ecology of submarine features such as fjords, sand banks, coral reefs, seamounts, canyons, mud volcanoes and spreading ridges has been revealed in unprecedented detail. This book provides a synthesis of seabed geomorphology and benthic habitats based on the most recent, up-to-date information. Introductory chapters explain the drivers that underpin the need for benthic habitat maps, including threats to ocean health, the habitat mapping approach based on principles of biogeography and benthic ecology and seabed (geomorphic) classification schemes. Case studies from around the world are then presented. They represent a range of seabed features where detailed bathymetric maps have been combined with seabed video and sampling to yield an integrated picture of the benthic communities that are associated with different types of benthic habitat. The final chapter examines critical knowledge gaps and future directions for benthic habitat mapping research. Reviews and compares the different methodologies currently being used Includes global case studies Provides geological expertise into what has traditionally been a biological discipline

New geophysical techniques (multibeam echo sounding and 3D seismics) have revolutionized high-resolution imaging of the modern seafloor and palaeo-shelf surfaces in Arctic and Antarctic waters, generating vast quantities of data and novel insights into sedimentary architecture and past environmental conditions. The Atlas of Submarine Glacial Landforms is a comprehensive and timely summary of the current state of knowledge of these high-latitude glacier-influenced systems. The Atlas presents over 180 contributions describing, illustrating and discussing the full variability of landforms found on the high-latitude glacier-influenced seafloor, from fjords and continental shelves to the continental slope, rise and deep-sea basins beyond. The distribution and geometry of these submarine landforms provide key information on past ice-sheet extent and the direction and nature of ice flow and dynamics. The papers discuss individual seafloor landforms, landform assemblages and entire landsystems from relatively mild to extreme glacimarine climatic settings and on timescales from the modern margins of tidewater glaciers, through Quaternary examples to ancient glaciations in the Late Ordovician.

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.

The Phantom Atlas is a guide to the world not as it is, but as it was imagined to be. It's a world of ghost islands, invisible mountain ranges, mythical civilizations, ship-wrecking beasts, and other fictitious features introduced on maps and atlases through mistakes, misunderstanding, fantasies, and outright lies. This richly illustrated book collects and explores the colorful histories behind a striking range of real antique maps that are all in some way a little too good to be true. Author Edward Brooke-Hitching investigates the places where exploration and mythology meet, using gorgeous atlas images as springboards for tales of the deranged buccaneers, seafaring monks, heroes, swindlers, and other amazing stories behind cartography's greatest phantoms.

Oceans and the Atmospheric Carbon Content, presents an interdisciplinary overview of the role of the oceans as a carbon sink and its relation with pH increasing trends and climate change. This volume discusses topics such as: climate variability during the last deglaciation, based on a high-resolution pollen analysis; the potential impact of CO2 from large metropolitan areas over the adjacent coastal zones and the importance of having high resolution atmospheric CO2 data to estimate accurately air-sea CO2 exchanges; present- day CO2 fluxes in the coastal ocean and their potential feedbacks under global climate change; phytoplankton community responses to climate change with emphasis on decreasing pH trends in sea water and its ecological effects; pH decrease and its effects on sea-water chemistry from a ten year time-series; the effect of acidification on metal bioaccumulation; the effects of increasing temperatures and acidification on contaminant dynamics and availability to biota; the prevention of potential environmental impacts related to the geological sequestration of CO2. The book provides an updated synthesis of current concerns related to global change trends in the oceans with a strong emphasis on acidification. The content draws attention to the importance of dealing with observed global change trends and their effects upon the oceans using an interdisciplinary approach due to their complexity and interlinks between different areas of knowledge.
