Last year, David and Janet Carle traveled the United States along the 38th parallel, investigating water issues from the Chesapeake to California for their upcoming book.

Yesterday, the Carles embarked on the European leg of their worldwide journey, beginning at Sao Miguel Island in the Azores archipelago, then on to the wetlands of Portugal. They’ll look at Spain’s efforts to use renewable energy to power desalination plants, help with the annual survey of migrating raptors in Sicily, visit sea turtle habitats and Lake Trichonis in Greece, and explore Turkey’s salt lakes and dams on the Tigris and Euphrates rivers. They’ll chronicle their travels on their blog, Parallel Universe: 38° North, and we’ll be cross-posting their updates here.
