Watching the sand flow

    For the past several years, the American Geophysical Union (AGU) has hosted the AGU Cinema program at their annual Fall meeting in San Francisco. They posted some of 2016's best entries online. 
    The one that caught my eye was the 4-minute, "Drift: Measuring the Movement of Sand Dunes", produced by Josh Silberg and the Hakai Institute. Filming took place on remote and beautiful Calvert Island off the coast of British Columbia.  TWO THUMBS UP!
    From the authors, 'Sand dunes are constantly changing. Change is natural for a dune. If left to nature, they’re quite resilient and tend to recover from forces that erode away the sand. But we don’t know an awful lot about how these dunes recover, so Hakai Institute scientists are watching the dunes drift, one sand grain at a time.'
