Solving the puzzle under the sea : Marie Tharp maps the ocean floor
(Book)

"A Paula Wiseman Book."

Includes bibliographical references.

Filled with gorgeous illustrations by acclaimed artist Raúl Colón, this illustrated biography shares the story of female scientist, Marie Tharp, a pioneering woman scientist and the first person to ever successfully map the ocean floor. Marie Tharp was always fascinated by the ocean. Taught to think big by her father who was a mapmaker, Marie wanted to do soething no one had ever done before: map the bottom of the Altantic Ocean. Was it even possible? Not sure if she would succeed, Marie decided to give it a try. Throughout history, others had tried and filed to measure the depths of the oeans. Sailors lowered weighted ropes to take measurements. Even today, scientists are tying to measure the depth by using echo sounder machines to track how long it would take a sound wave sent from a ship to the sea floor to come back. But for Marie, it was like piecing together an immense jigsaw puzzle. Despite past failures and challenges - sometimes Marie would be turned away from a ship because having a woman on board was "bad luck"--Marie was determined to succeed. And she did, becoming the first person to chart the ocean floor, helping us better understand the planet we call home. --,Frm amazon.com
