Humans have visited only a tiny fraction of the seafloor and an even tinier fraction of the vast volume of deep ocean waters. Yet our oceans are slowly revealing incredible details about the origins of life, the evolution of our planet, and the prospects for sustaining human life on Earth. This text examines the interrelated biological, chemical, physical, and geological processes that occur in the oceans and the atmosphere. The effects of humans on the oceans, climate change, and coastal ecosystems are a primary theme throughout the book.
Oceanographer and photographer Douglas A. Segar's approach to learning about marine life is to examine a variety of marine ecosystems so the reader sees the ocean and the organisms that live in each part of the oceans as a composite of factors such as salinity, temperature, light, nutrients, currents, and depth. Introduction to Ocean Sciences is lavishly illustrated throughout with full-color photographs, diagrams, and maps.
