What Lies Beneath? Revealing Coastal Processes Through Mapping

Abstract

Coastal areas are changing as a result of natural and human activities, and these dynamics create risks for citizens and communities. Science is needed to map and measure coasts and oceans, and many new tools exist to enhance our knowledge. In this chapter, some of the methods being employed around the world are discussed including GIS, multibeam sonar and aerial imaging. Stories from past and recent research are used to explain the approaches as well as their scientific and societal value. Weaving together experiences from ancient worlds, on distant shores and with crocodiles, I explain how and why we learn about what lies beneath the waves and along our shores.
