Présentation de l'éditeur

The air we breathe is twenty-one percent oxygen, an amount higher than on any other known world. While we may take our air for granted, Earth was not always an oxygenated planet. How did it become this way? Oxygen is the most current account of the history of atmospheric oxygen on Earth. Donald Canfield--one of the world's leading authorities on geochemistry, earth history, and the early oceans--covers this vast history, emphasizing its relationship to the evolution of life and the evolving chemistry of the Earth. With an accessible and colorful first-person narrative, he draws from a variety of fields, including geology, paleontology, geochemistry, biochemistry, animal physiology, and microbiology, to explain why our oxygenated Earth became the ideal place for life.

Describing which processes, both biological and geological, act to control oxygen levels in the atmosphere, Canfield traces the records of oxygen concentrations through time. Readers learn about the great oxidation event, the tipping point 2.3 billion years ago when the oxygen content of the Earth increased dramatically, and Canfield examines how oxygenation created a favorable environment for the evolution of large animals. He guides readers through the various lines of scientific evidence, considers some of the wrong turns and dead ends along the way, and highlights the scientists and researchers who have made key discoveries in the field.

Showing how Earth's atmosphere developed over time, Oxygen takes readers on a remarkable journey through the history of the oxygenation of our planet.

1.0 étoiles sur 5 Kindle edition not worth it. Bought it, returned it. 29 janvier 2014
Par J. C. Petts - Publié sur

I started reading this with interest but returned it very quickly.

Now Donald Canfield is a respected geochemist and I'm sure he has a great story to tell: indeed the opening print material was excellent.

I'm sure the print edition is fine, but I definitely didn't like the black square with the words "Please refer to the print edition for this content" or similar message when I clicked on an image link. The Kindle edition is just over $15, with the print edition a little over $20. This is a huge rip-off for the Kindle edition.

When something like this happens the price should be $3-5, with a BIG warning saying "BE CAREFUL: critical content which is essential to getting the message across in a scientific fashion is flat out missing, which is why this is so much cheaper than the print edition!"

I ended up with "Oxygen: The molecule that made the world", by Nick Lane. Yes, it's a little bit less up-to-date, and the images aren't perfect, but at least they are there.

Princeton University Press should be ashamed - they are doing nobody any favors with this gobbler.

Correcting error on 31 Jan 2014 - Canfield is a geobiologist, not geochemist.

5.0 étoiles sur 5 Note from Publisher 21 février 2014

Unfortunately the rights holder to Plate 5 was not willing to grant rights to include it in the digital edition. We share the customer's frustration, but many readers who prefer Kindle to print are enjoying the book in spite of this one missing illustration.

3.0 étoiles sur 5 Distracted by the academic chit-chat 17 mars 2014
Par Little Teacher on the Prarie - Publié sur
Format:Relié|Achat authentifié par Amazon
I found Canfield's obsession with inclusion of academic chit-chat and academic crediting in the text to be distracting, not endearing as he perhaps intended. I spent years in academia and I understand it is important to give out atta-boys and atta-girls, but not in the middle of the story. Save it for publication in specialist academic journals where such score keeping really matters and keep it in footnotes in a book like this aimed at a wider audience. For an example, see p. 43 and the digression on hotel repairs by his mentor Dave Des Marais.

A glossary would have been helpful, too. I've also been reading Nick Lane's book on oxygen for an overlap in coverage, which is a much more no-nonsense style of writing.

5.0 étoiles sur 5 A personal and excellent package of current geobiology 3 avril 2014
Par emma hammarlund - Publié sur
I think the storytelling in this book works really well, especially considering the daunting challenge to merge a personal account with accurate science - while keeping the flow. The book explains what we understand today of oxygen dynamics on Earth, covering all its time, while it also gives us the road to this knowledge, the evidence, the people involved and the implications. It is really not a text book, luckily. Instead, the voice simultaneously tells us about current science and of a personal and spectacular journey along this front. You sort of get to watch an evolving scientific landscape, from the author’s shoulder, while it still is in motion. The book also made me see what kind of jet fuel we really have in curiosity itself. How it constantly makes us dig for clues so that we, together, dare attempt to figure out what made us show up on exactly this scene. I'm grateful for this account, for the perspectives, for the rare and personal packaging of science and for being welcome aboard to hear and see it all.

4.0 étoiles sur 5 very good overview 23 mars 2014

Even so the only review posted at the time I purchased the book was severely negative, reading the review made it clear that all the writer complained about was a downloaded ebook which had problems presenting the photos and images (who reads science books with complex images in a downloaded version anyhow?)
Never the less, this negative review, having absolutely nothing to do with the work itself (rather with presentation issues caused by the form of publishing) may have prevented many a potential reader from buying the book - it certainly nearly did so for me.
I purchase the book anyhow; and I am glad I did! It is the best new and updated view of the role of oxygen on our planet I could find. It certainly requires a little more understanding of basic chemistry than some other popular books about the subject. However, it is not too much for a layperson with a decent basic education and it helps clarify some of the specific points.
