Book excerpt: Improving oceanographic data collection involves two components: improving instrumentation, and improving the processing and analysis of resulting measurements. While advancing technology has improved and expanded data collection, processing these data has become a significant problem for under-resourced academic labs, rendering much of these data underutilized. The experiments described in this dissertation are contributions to the effort of improving data processing in oceanography. Chapter 1 examines parametrization of particle size distribution measurements in the Arctic, collected during decades of field expeditions by Dariusz Stramski, Rick Reynolds, and others. Experiments suggest that the commonly-used Junge-type power law model for parametrizing particle size distributions is insufficient, and cumulative distribution functions may offer a superior alternative. Particle size directly physically affects light, so the particle size distribution affects the signals of optical instruments. These results will increase the utility of satellite imagery, both by assisting the measurement of particle size from satellites, and by improving understanding of the impact of different seawater characteristics on optical signals. Chapter 2 discusses cutting-edge, technology-enabled survey image and 3D model techniques for studying coral reefs. The report focuses on lessons learned by the Sandin/Kuester labs from a decade of experience. Improving and standardizing data collection in the field allows research groups to pool datasets and compare results. Pooled databases are valuable for developing processing and analytical tools like neural networks, make those tools useful to more research groups, and enable ecological analysis at larger scales. Chapters 3 and 4 evaluate neural-network-assisted tools that can expedite taxonomic labeling of survey image products such as orthoprojections and pointclouds. Chapter 3 contains the first published investigation of 3D coral pointcloud segmentation with 3D neural networks. This new technology shows great promise, as evidenced by the time savings (36%) and high prediction accuracy in some contexts (~70-90%) recorded by our experiments, but requires more comprehensive, standardized datasets than what is currently available to fully develop or confidently evaluate. These tools are already capable of increasing the utility of survey imagery by expediting their annotation, which is necessary for many types of analysis, and further development will further improve their performance.

Available in PDF, EPUB and Kindle. Book excerpt: Optical Remote Sensing is one of the main technologies used in sea surface monitoring. Optical Remote Sensing of Ocean Hydrodynamics investigates and demonstrates capabilities of optical remote sensing technology for enhanced observations and detection of ocean environments. It provides extensive knowledge of physical principles and capabilities of optical observations of the oceans at high spatial resolution, 1-4m, and on the observations of surface wave hydrodynamic processes. It also describes the implementation of spectral-statistical and fusion algorithms for analyses of multispectral optical databases and establishes physics-based criteria for detection of complex wave phenomena and hydrodynamic disturbances including assessment and management of optical databases. This book explains the physical principles of high-resolution optical imagery of the ocean surface, discusses for the first time the capabilities of observing hydrodynamic processes and events, and emphasizes the integration of optical measurements and enhanced data analysis. It also covers both the assessment and the interpretation of dynamic multispectral optical databases and includes applications for advanced studies and nonacoustic detection. This book is an invaluable resource for researches, industry professionals, engineers, and students working on cross-disciplinary problems in ocean hydrodynamics, optical remote sensing of the ocean and sea surface remote sensing. Readers in the fields of geosciences and remote sensing, applied physics, oceanography, satellite observation technology, and optical engineering will learn the theory and practice of optical interactions with the ocean.

This book was released on 1986 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Optical Dynamics Experiment (ODEX) was an interdisciplinary experiment to study the relation of physical forcing, biological processes, and the structure of optical parameters in the open ocean. This data report presents the data collected with the spectral radiometer package, and the particle size analysis of discrete water samples taken from CTD casts by the Oregon State Univ. Optical Oceanography Group. The ODEX cruise of Oct and Nov 1982 occupied 1984 stations along a transect from the California coast at 35 deg N to a study area covering the subtropical front near 32 deg N, 142 deg W. Plots are presented of hydrographic parameters, beam attenuation, percentage of surface irradiance at 9 wave-lengths, and diffuse attenuation at 5 wavelengths. Lists of the same parameters as well as discrete and total visible irradiance are presented. Keywords: Sea water; Light transmission; North pacific ocean; Oceanographic data; Optical data; Irradiance measurements; Eastern North Co. Pacific Central Gyre.

Download or read book Outstanding Topics in Ocean Optics written by Dariusz Stramski and published by . This book was released on 2019 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.
