Discovery of Sound in the Sea Book I: Importance of Sound in the Sea focuses on sound in the ocean, both natural and human produced, and contains DOSITS content on topics related to marine animal sound production and reception and use of sound, along with a chapter on the potential effects of human produced sounds on marine animals. Discovery of Sound in the Sea Book II: Science of Underwater Sound focuses on the fundamental science of underwater sound, sound movement, and sound measurement, as well as advanced scientific content. Both interactive books contain high-resolution imagery, videos, and sound files. The content in these books is based on the DOSITS project, including its website (www.dosits.org). DOSITS content is based on well-understood scientific principles, peer-reviewed literature, and high-quality sources of scientific data. Independent underwater acoustics experts have reviewed all of the books’ content. Several topics in these books are areas of active scientific research; new information will be integrated into each eBook as peer-reviewed publications become available. Questions?
