        The Secret Life of Scientists & Engineers | Adrienne Block

        Meet geophysicist Adrienne Block in these videos from NOVA's "The Secret Life of Scientists & Engineers."  Adrienne studies global warming, and has mapped a mountain range in Antarctica beneath an ice sheet by sending out sonar signals from an airplane. She explains that water gets into ice streams from mountain ranges and helps them speed up, delivering great quantities of ice into the sea, which melts and raises the sea level. She also plays the bassoon. This resource is part of the NOVA: Secret Life of Scientists & Engineers Collection.
