Grad Student Rayle Examines Changing Meiofauna Biodiversity in Oiled Marshes Using Bioinformatics

Shearing typically occurs along coastal marshes when strong storms rip away the plants at the marsh edge. Because oiled shoreline sediment is in a weakened state and less able to securely hold plants in place, some Louisiana marshes that were heavily oiled following Deepwater Horizon are experiencing more shearing than usual.
