Public awareness of the importance of Antarctic research, particularly in relation to global problems, has increased. The book spans a broad spectrum of Antarctic science from the ozone hole to microbiology to the sea ice. The main focus is on the role of Antarctica and the Southern Ocean in the world climate system, e.g. the formation of sea ice and its relevance to ocean circulation, the biological pump in relation to CO2 release. The past climate history is revealed by the analysis of ice cores and sediments. Studies of plate tectonics and fossil records reach further back in earth history. Key words in the biological chapters are krill and the rich Antarctic benthos. Finally, the potential conflict between conservationists, researchers and tourists is discussed.Public awareness of the importance of Antarctic research, particularly in relation to global problems, has increased.
