About this book

The next hundred years will see profound changes in the Ross Sea and Southern Ocean, which will be magnified in subsequent centuries. The role of Antarctic seas in regulating global climate through biogeochemical cycling is likely to change as well, with feedbacks partially determining our greenhouse future. The record of past planetary change in polar ice cores and marine sediments also suggests future surprises, including abrupt, major climate changes with physical and biological consequences. Biogeochemistry of the Ross Sea presents the state of the science on such issues, and more.
