Soundings: A Biography of Marie Tharp

Book cover: Soundings A review in Maclean’s brought to my attention a book that came out two months ago: Hali Felt’s Soundings, a biography of Marie Tharp (1920-2006), who with her partner, Bruce Heezen, created the first global map of the ocean floor, discovered the Mid-Atlantic Ridge’s rift valley, and helped provide the evidence for plate tectonics. She’s a major figure in cartography and among women in science, so I thought I should bring this book to your attention, too. Another one to add to the to-read pile.

Previously (on The Map Room): Marie Tharp; Marie Tharp and Plate Tectonics.

You may have seen this already: a beautiful, painting-like visualization of the world’s surface ocean currents between June 2005 and November 2007, which NASA posted last month. The visualization is based on model data from the ECCO2 project. See also this short video on Flickr (Flash required). Image credit: NASA/Goddard Space Flight Center Scientific Visualization Studio.
