Pioneering geologist & oceanographer Marie Tharp changed our understanding of the ocean.
When Tharp sought a geology job at Columbia in 1948, women couldn’t go on research ships. So she was hired to assist male grad students.
Back then, many scientists still assumed the bottom of the ocean was featureless. Tharp figured out how to use data to create sketches of the ocean floor. Her hand-drawn maps helped develop plate tectonic theory. https://www.ncei.noaa.gov/news/marie-tharp #science #history
