The most complete text on dry suit diving.

This updated and revised second edition of John Heine's Scientific Diving Techniques covers the details of research methods underwater. Included are general scientific diving guidelines, an overview of aquatic habits and ecosystems, specialized diving equipment and procedures, locating and marking study sites, archaeology, measuring physical and biological factors, underwater experimentation and underwater photographing and videography for the scientist. There are over 500 references to original scientific techniques. Also included are training exercises to aid Diving Safety Officers in training scientific divers.

The use of optical methodology, instrumentation and photonics devices for imaging, vision and optical sensing is of increasing importance in understanding our marine environment. Subsea optics can make an important contribution to the protection and sustainable management of ocean resources and contribute to monitoring the response of marine systems to climate change. This important book provides an authoritative review of key principles, technologies and their applications.The book is divided into three parts. The first part provides a general introduction to the key concepts in subsea optics and imaging, imaging technologies and the development of ocean optics and colour analysis. Part two reviews the use of subsea optics in environmental analysis. An introduction to the concepts of underwater light fields is followed by an overview of coloured dissolved organic matter (CDOM) and an assessment of nutrients in the water column. This section concludes with discussions of the properties of subsea bioluminescence, harmful algal blooms and their impact and finally an outline of optical techniques for studying suspended sediments, turbulence and mixing in the marine environment. Part three reviews subsea optical systems technologies. A general overview of imaging and visualisation using conventional photography and video leads onto advanced techniques like digital holography, laser line-scanning and range-gated imaging as well as their use in controlled observation platforms or global observation networks. This section also outlines techniques like Raman spectroscopy, hyperspectral sensing and imaging, laser Doppler anemometry (LDA) and particle image velocimetry (PIV), optical fibre sensing and LIDAR systems. Finally, a chapter on fluorescence methodologies brings the volume to a close.With its distinguished editor and international team of contributors, Subsea optics and imaging is a standard reference for those researching, developing and using subsea optical technologies as well as environmental scientists and agencies concerned with monitoring the marine environment. - Provides an authoritative review of key principles, technologies and their applications - Outlines the key concepts in subsea optics and imaging, imaging technologies and the development of ocean optics and colour analysis - Reviews the properties of subsea bioluminescence, harmful algal blooms and their impact

This book by artist, diver, and editor-in-chief of an underwater magazine Jürgen Claus is a milestone among the books dedicated to the planet sea. It is a knowledge-rich overview, created from facts and experiences, of three main themes that have never been described in context. Marine architectures from both the Pacific and Atlantic regions have now moved from vision to reality. Whether it is a sail-shaped architecture in Nouméa or a whale-shaped one in the Arctic region. Special attention is paid by Prof. Claus to post-disaster architecture. The book will encourage young readers to design metabolic buildings themselves. That the seascape has also become a fluid studio for visual artists may come as a surprise. The works of art, some of which the author has experienced first-hand, have intertwined with an ecological, sustainable way of working. And this is also true to a special degree for the sound artists. They realize their sonic worlds with recordings from the sounding world underwater, a concert hall of hitherto unknown dimensions. The author’s experience as a professor of media art with students flows into the description of multimedia or media-related ocean installations. Here the book becomes a stimulus for realizing one’s own experiences.
