Chapter 1 contains a new guest essay written by Dr. Marcia McNutt and Captain Ian Young on the roles of the chief scientist and ship's captain in planning and executing a successful oceanographic expedition. In Chapter 2 we have included a discussion of the possible existence of extraterrestrial oceans in our solar system. Chapter 3 includes a Field Notes box on Project Neptune on the Juan de Fuca plate. Chapter 3's discussion of plate tectonics, especially convergent plate boundaries, has been completely revised and updated, with new figures added. Giant Hawaiian landslides are now discussed in Chapter 4's Field Notes box. In Chapter 5 the description of the interaction of light and seawater has been extensively revised, and the attenuation of light with depth is discussed in greater detail. Chapter 6 includes a new description of the different units, including moles/liter, used in expressing the concentration of dissolved constituents in seawater. Chapter 7 contains an updated and significantly revised discussion of ENSO. Chapter 8 includes an updated discussion of oceanic internal structure and circulation. It also covers topics in upwelling and downwelling, the layering of the oceans, and updated material on sampling methods and measurement techniques.
