Download or read book Underwater Optics written by Seibert Q Duntley and published by . This book was released on 1966 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: The irradiance pattern was measured for the propagation of a collimated beam of light underwater. A neodymium-doubled green laser was transmitted horizontally at a six foot depth in Lake Winnipesaukee, N.H. The irradiance was measured at distances from 0 to 100 feet and for off-axis angles from 0 to 58 degrees. The water had an attenuation length of 4.54 ft/ln and an absorption coefficient of 0.0446 ln/ft. The ratio of attenuation coefficient to absorption coefficient was 4.94. The fractional power contained within a cone of various angles was computed. At 20 attenuation lengths only 10% of the total power is contained within a cone of 4 degrees whereas at 4 attenuation lengths this same cone contains 50% of the power. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Partnerships in Marine Research: Case Studies, Lessons Learned, and Policy Implications provides a thorough assessment of this important approach to Marine Research. It starts by looking at the problems faced by scientists as they conduct investigations within Marine Research; it then leads into case studies where partnerships have been successful and concludes with the ultimate intended outcomes for this approach. Through these sections of the book, an experience-based framework for sustainable partnerships and science is introduced, including some key elements identifiable in the case studies presented. Elements of the framework are implicitly present in each of the case studies, including four key elements: flexibility of the partnership system, diversity (of partners and functions), redundancy, and connectivity. These four elements are important aspects of the partnership resilience and crucial to sustain and to achieve its goals. Partnerships in Marine Research guides the sustainable planning and implementation of future ocean science and technology projects, and provides a fundamental tool for researchers, engineers, and decision makers involved in collaborative Marine Research. - Presents chapters from a diverse group of contributors, enabling a broad and deep perspective - Includes case studies to connect the reader to successful marine research partnerships - Provides key elements of resilient and sustainable partnerships throughout different project phases and a framework for supporting research partnerships in the future - Projects lessons learned and conclusions toward a plausible 2050 scenario to advance and reach sustainable development goals while aiming to rebuild marine life in the Global Ocean

Download or read book Oceanography from Space written by Vittorio Barale and published by Springer Science & Business Media. This book was released on 2010-04-26 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: To all those sailors / Who dreamed before us / Of another way to sail the oceans. The dedication of this Volume is meant to recall, and honour, the bold pioneers of ocean exploration, ancient as well as modern. As a marine scientist, dealing with the oceans through the complex tools, ?lters and mechanisms of contemporary research, I have always wondered what it was like, in centuries past, to look at that vast ho- zon with the naked eye, not knowing what was ahead, and yet to sail on. I have tried to imagine what ancient sailors felt, when “the unknown swirls around and engulfs the mind”, as a forgotten author simply described the brave, perhaps reckless, act of facing such a hostile, menacing and yet fascinating adventure. Innovation has always been the key element, I think, for their success: another way, a better way, a more effective, safer and worthier way was the proper answer to the challenge. The map of our world has been changed time and again, from the geographical as well as the social, economic and scienti?c points of view, by the new discoveries of those sailors. One of the positive qualities of human beings is without doubt the inborn desire to expand their horizons, to see what lies beyond, to learn and understand.

Download or read book Outstanding Topics in Ocean Optics written by Dariusz Stramski and published by MDPI. This book was released on 2019-04-23 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ocean optics is a branch of oceanography which is firmly embedded in studies of a great variety of ocean science and engineering questions. The interactive nature between radiative transfer of light and various dissolved and particulate constituents of seawater is at the core of ocean optics science and applications. The transfer of radiant solar energy has vital implications to life and climate on Earth, and the large variety of subjects of ocean optics ranges from the subtle problems of physical optics to optical remote sensing towards a better understanding of ocean biology, biogeochemistry and ecosystems and their roles in the Earth's system processes. The intention of this book is to present a collection of papers that generally share a common denominator of frontier topics in ocean optics which are unique, uncommon or outstanding in the literature, and to provide a balanced view of the extraordinary breadth of research in this field. Topics as diverse as measurements and modeling of radiative transfer, light fields, light scattering and polarization, ocean color, benthic optical properties, and the use of optics for characterizing seawater constituents are addressed in this book. The book is expected to be of interest and useful to a broad audience of professional ocean scientists, engineers and advanced students with an interest in ocean optics and applications of optical methods in oceanography.

Download or read book Advances in Biophotonics written by B.C. Wilson and published by IOS Press. This book was released on 2005-11-15 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: The field of biophotonics is rapidly emerging in both academia and industry. It is the convergence of photonics and life sciences. Photonics - the science and technology of light generation, manipulation and measurement - has itself seen a remarkable expansion in the past 20 years, both in research and in commercialization, particularly in telecommunications. The life sciences have an increasing need for new technologies to which photonics can make significant contributions. As biology and medicine move into the post-genomics era, it is increasingly important to have highly sensitive tools for probing cells, tissues and whole organism structure and functions. Through photonic technologies optical fibers and sensitive imaging detectors, these measurements can often be done in a non- or minimally-invasive way, which is tremendously valuable for clinical and remote-sensing applications. In clinical medicine the ability to probe and image tissues is leading to a wide range of novel diagnostic methods; examples of these techniques are given in this book. Finally, the new field of nanotechnology is now penetrating into biophotonics. Examples include the use of nanoparticles such as metal nanospheres or rods and quantum dots for enhanced cell and tissue imaging and local light energy absorption. As will be evident, this volume is not intended as a comprehensive text on biophotonics. Rather, it presents ‘snapshots’ of some of the most exciting developments, from a perspective of photonic technologies, and life-sciences applications.
