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 first part of the book 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. Part three reviews subsea optical systems technologies.

Key Features: 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.
