In college, Marie tried lots of different subjects. Her father always told her, “When you find your life’s work, make sure it is something you can do, and most important, something you like to do.” She took classes in art, and music, and math, and teaching, and geology. She couldn’t quite make up her mind.
Then one day, her geology teacher pointed to a big map of the earth. Almost three-fourths of it was plain blue ocean. What was under all that water? Was it flat, like a beach? Or were there mountains and valleys, as on land? No one knew. That got Marie’s attention. All that blue blank space—waiting to be mapped.
Exploring with Numbers
Marie became a geologist. She got a job with a group studying the oceans. But Marie wasn’t allowed to go to sea. The Navy did not let women on ships. Marie’s job was to stay in the office and do math and draw. But that didn’t mean she couldn’t explore.
Part of Marie’s job was to keep track of all the data that the ships sent back. One number she often wrote down was the depth of the water. Ships measured this with sonar—sending out a sound ping and timing the echo. Often they made many measurements each day. In the old days, sailors lowered a weight on a string until it hit bottom, then measured the string.
