"In sum, I believe that every organization active in remote sensing will find Dr. Kramer's book to be an essential addition to its technical library, and I believe that every serious practitioner of remote sensing will find it a permanently useful and vital reference." John H. McElroy, Dean of Engineering, The University of Texas and Chair of the Committee on Earth studies of the U.S. National Research Council's Space Studies Board)
The emphasis now placed on the concept of sediment cells as boundaries for coastal defence groups, and the development of SMPs, should help CPAs realise the importance of natural processes at the coast when designing defence and protection schemes. However, this will only be the case where defence groups exist, and where CPAs take up the challenge of developing SMPs. Coastal landscapes have been produced by the natural forces of wind, waves and tides, and many are nationally or internationally important for their habitats and natural features. Past practices at the coast, such as the construction of harbours, jetties and traditional defence systems may have contributed to the deterioration of the coast. English Nature (1992) have argued that if practices and methods of coastal defence are allowed to continue, then coastlines would be faced with worsening consequences, including: The loss of mudflats and the birds which live on them Damage to geological Sites of Special Scientific Interest (SSSIs) and scenic heritage by erosion, due to the stabilisation of the coast elsewhere Cutting of sediment supplies to beaches resulting in the loss of coastal wildlife Cessation through isolation from coastal processes, of the natural operation of spits, with serious deterioration of rare plants, animals and geomorphological and scenic qualities (English Nature, 1992) A number of designations, provided by national and international legislation do exist to aid conservation.
The northern North Atlantic is one of the regions most sensitive to past and present global changes. This book integrates the results of an interdisciplinary project studying the properties of the Greenland-Iceland-Norwegian Seas and the processes of pelagic and benthic particle formation, particle transport, and deposition in the deep-sea sediments. Ice-related and biogeochemical processes have been investigated to decipher the spatial and temporal variability of the production and fate of organic carbon in this region. Isotopic stratigraphy, microfossil assemblages and paleotemperatures are combined to reconstruct paleoceanographic conditions and to model past climatic changes in the Late Quaternary. The Greenland-Iceland-Norwegian Seas can now be considered one of the best studied subbasins of the world`s oceans.
This volume is one of the most significant results of the conference Science-Technology Synergy for Research in Marine Environment: Challenges for the XXI Century held in Erice and Ustica, Italy, September 1999. It presents state of the art developments in technology and scientific research in sea floor observatories. Scientific conclusions of earth science and environmental studies obtained from these observatories as well as results from long term monitoring are provided. Descriptions of new technologies enabling deep sea long term observatories are offered and marine environment and risk assessment issues are discussed.This is the first work detailing recent and on going experiments world wide specifically devoted to deep sea multi disciplinary observation systems, the technology enabling sea floor observatories, and the presentation of first results from these systems.
