With contributions from leading researchers in science and engineering, this book provides a global perspective on submarine mass movements and their consequences. Authors report on new findings from fundamental as well as site-specific studies from around the world. All studies relied on the most recent technologies, including multi-beam sonar imaging techniques, 3D seismic analysis, slope stability analysis, debris flow, and tsunami modeling.
The deep sea covers over 60% of the surface of the earth, yet less than 1% has been scientifically investigated. There is growing pressure on deep-sea resources and on researchers to deliver information on biodiversity and the effects of human impacts on deep-sea ecosystems. Although scientific knowledge has increased rapidly in recent decades, there exist large gaps in global sampling coverage of the deep sea, and major efforts continue to be directed into offshore research. Biological Sampling in the Deep Sea represents the first comprehensive compilation of deep-sea sampling methodologies for a range of habitats. It reviews the real life applications of current, and in some instances deve...
Geomorphometry is the science of quantitative terrain characterization and analysis, and has traditionally focused on the investigation of terrestrial and planetary landscapes. However, applications of marine geomorphometry have now moved beyond the simple adoption of techniques developed for terrestrial studies, driven by the rise in the acquisition of high-resolution seafloor data and by the availability of user-friendly spatial analytical tools. Considering that the seafloor represents 71% of the surface of our planet, this is an important step towards understanding the Earth in its entirety. This volume is the first one dedicated to marine applications of geomorphometry. It showcases stu...
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 mar...
Antarcticness joins disciplines, communication approaches and ideas to explore meanings and depictions of Antarctica. Personal and professional words in poetry and prose, plus images, present and represent Antarctica, as presumed and as imagined, alongside what is experienced around the continent and by those watching from afar. These understandings explain how the Antarctic is viewed and managed while identifying aspects which should be more prominent in policy and practice. The authors and artists place Antarctica, and the perceptions and knowledge through Antarcticness, within inspirations and imaginations, without losing sight of the multiple interests pushing the continent’s governanc...

Submarine mass movements are a hidden geohazard with large destructive potential for submarine installations and coastal areas. This hazard and associated risk is growing in proportion with increasing population of coastal urban agglomerations, industrial infrastructure, and coastal tourism. Also, the intensified use of the seafloor for natural resource production, and deep sea cables constitutes an increasing risk. Submarine slides may alter the coastline and bear a high tsunamogenic potential. There is a potential link of submarine mass wasting with climate change, as submarine landslides can uncover and release large amounts greenhouse gases, mainly methane, that are now stored in marine ...
This United Nations report examines the current state of knowledge of the world's oceans, for policymakers, and provides a reference for marine science courses.
"This is the story of a journey. It begins in a small, slightly overfull office in Sydney, Australia and ends in the unremitting heat of the Atacama Desert coast in Chile. To get from A to B though is no straight line, it takes many geographical and anecdotal tangents. The journey is one of discovery. It describes my part in the emergence of a new and extremely violent science - unravelling the mysteries of past tsunamis. There are two sides to the story of every tsunami - the careful piecing together of the physical evidence for these catastrophic events and the patient assembly of the jigsaw puzzle that often reflects the less tangible signs, the human story. After all, the only reason we ...
This eBook is a collection of articles from a Frontiers Research Topic. Frontiers Research Topics are very popular trademarks of the Frontiers Journals Series: they are collections of at least ten articles, all centered on a particular subject. With their unique mix of varied contributions from Original Research to Review Articles, Frontiers Research Topics unify the most influential researchers, the latest key findings and historical advances in a hot research area!
