A discovery about the moon made in the 1960s is helping researchers unlock secrets about Earth's oceans today. By applying a method of calculating gravity that was first developed for the moon to data from NASA's Gravity Recovery and Climate Experiment, known as Grace, researchers have found a way to measure the pressure at the bottom of the ocean.
