Amazon calculates a product’s star ratings based on a machine learned model instead of a raw data average. The model takes into account factors including the age of a rating, whether the ratings are from verified purchasers, and factors that establish reviewer trustworthiness.
"Oceans" is another in the "A Very Short Introduction" series of books. It provides a surprisingly detailed survey of the world's oceans in less than 200 pages. The author is an exceptional writer, easily able to engage the general reader from page to page in working through some challenging topics. The narrative is brisk and generally straightforward. The text is enhanced by lots of relatively easy to understand charts and maps.
The text suffers in places from poor editing. For example, the Exon Valdez oil spill took place on Prince William Sound in South-Central Alaska, not north of the Arctic Circle. That the Great Lakes of North America are hopelessly polluted and dead would probably come as a surprise to the U.S. EPA and its Canadian equivalent. Be warned, the author can't resist pounding the table every few pages on AGW, even though he admits its effects can't be measured with any precision. Cautiously recommended as a good introduction to the topic.
