Marie Tharp mapping the ocean floor — 2 books one podcast
Book Reviews / September 15, 2016

                    Marie Tharp was a brilliant and determined woman. She faced institutionalized discrimination against women in her field and pushed through to be a leader. Her work helped us understand our world through plate tectonics and ocean basins better. By combining  and connecting distinct research trips of transects and bathymetric profiles across the ocean, she created a whole picture view of the ocean. Her meta-analysis resulted in maps that revealed patterns of the whole earth that explained as much above sea level as it did below in the abyss. To celebrate her work I’m presenting two books and and interview with one of the authors. Both of these books will enlighten you to how Marie Tharp was a pivotal influence on our consciousness about the structure of the world. Both are well written (and for well illustrated) to bring to us the story of how she pulled information from transoceanic trips to interpolate a pattern that reinforced emerging ideas about the structure of our planet–ideas that during her life were considered revolutionary by some and derisively dismissed by others. Geographic literacy is a topic dear to my heart and the education of children is essential, so…

Title: Plate Tectonics: An Insider’s History Of The Modern Theory Of The Earth Author: Naomi Oreskes Date/Year:  January 20, 2003 (Westview Press) Format: Paperback and Hardcove Language: English Reviewer: cartonaut We rely on coordinates, often using them as an absolute fixed location. But we often don’t add time nor recognize the fact that the ground is not fixed while the coordinate is. I live in Sonoma County, California. The part of the North American Plate upon which Sonoma County rides moves on average about 2 centimeters a year north at a velocity a little slower than the rotating edge of the Pacific Plate to my west (west of the San Andreas Fault) which is moving north around 10 centimeters a year. The rest of the North American Plate (roughly the part west of Nevada) moves about 2 centimeters a year to the west-southwest That means that the coordinates for my desk chair are about four feet north of that location’s coordinates when I was born (in that time we’ve also invented and accepted the concept of Plate Tectonics). Also a noticeable shift in my life time in the location of the parcel that the chair sits inside…more than my outstretched arms, more than the…
