Mixing it Up

In WHOI’s Geophysical Fluid Dynamics Laboratory (GFD), scientists study small versions of ocean currents, eddies, and flows. Scientist Claudia Cenedese and graduate students in the Physical Oceanography Department held public open-houses in the GFD to highlight this research. Here, Anna Wargula (blue shirt), a student in the  MIT-WHOI Joint Program, explains a tank demonstration of densities, turbulence, and mixing to WHOI librarian and archivist Ellen Levy and others. Battery-operated fish swimming from layers of less-dense clear water to denser green water created visible eddies, mixing the layers.(Photo by Tom Kleindinst, Woods Hole Oceanographic Institution)
