In the Prologue chapter there is a significant amount of new material on the history of oceanography, as well as an updated section on oceanography of the recent past, present, and future.
In chapter 1 new material is added on the origin of the oceans. The discussions of the Earth's internal structure and the characteristics of plates and their boundaries has been
extensively rewritten and many new figures have been added.
The section in chapter 3 describing the characteristics of marine sediments has been completely revised and a new section on gas hydrates has been added.
In chapter 4 a new section has been added on temperature and heat before discussing changes in the state of water.
Chapter 5 now begins with a new section explaining the pH scale and the pH of seawater in order to form a foundation for the discussion of seawater chemistry.
Both chapters 6 and 7 have been renamed and reorganized. Chapter 6 is now named "The Structure and Motion of the Atmosphere." It focuses exclusively on atmospheric processes critical to understanding the links between the atmosphere and the oceans. Chapter 7 is now entitled "Circulation and Ocean Structure." This chapter includes a revised discussion of ocean density structure and covers topics in vertical circulation, upwelling and downwelling, the layering of the oceans, and updated material on sampling methods and measurement techniques.
The material in chapter 8 has been reordered and sections on convergence and divergence have been rewritten to enhance clarity.
Chapter 9's discussion of Energy from Waves, and the Box "Tsunami Warning Systems" have both been updated.
The tide and current tables have been updated in chapter 10.
The discussions of beach dynamics and beach types in chapter 11 have been reordered for clarity and the material previously in chapter 12 on modifying beaches has been moved to chapter 11.
In chapter 12 the discussion of the Gulf of Mexico dead zone has been updated and rewritten.
Chapter 13 has a new name, "The Living Ocean"; the chapter has been completely revised and rewritten. More emphasis is given to ocean biology and there are new sections on ocean biology, groups of organisms, and environmental zones. Symbiotic relationships are now included.
Chapter 14 has new information on the roles of nitrogen andiron.
Chapter 15 has updated material on the krill harvest, more information on the microbial loop, and the section on Harmful Algal Blooms has been revised and updated.
There is revised and expanded information on skates and rays, marine mammal populations, and bathypelagic organisms in chapter 16. In addition, all fisheries data in chapter 16 has been updated.
Chapter 17 has new and revised information on corals including bleaching, predation, disease, and the effect of human activities. New information on Lost City vents is included in chapter 17 and all harvesting data has been updated as well.
