World Ocean Radio, from the World Ocean Observatory (http://www.thew2o.net), is a series hosted by Peter Neill that covers a broad spectrum of issues related to the oceans of the world. Topics include the world's largest cargo ship, the law of the sea, international maritime issues, navigation, pollution, ballast water and invasive species, and more. We will be posting some of our favorites here. Check back from time to time to see what's new.
