17th December: freeze core fun!

Anne: On Thursday at the American Geophysical Union meeting, Anne’s graduate student Stuart Baker gave a talk presenting results of his in-progress M.S. thesis research. Stuart’s research examines how subsurface properties of streambeds change in the months and years following stream restoration. Stuart employed a high density array of piezometers to make repeated hydraulic conductivity and head measurements in two streams. At the end of his field work, he extracted freeze cores (“gravel popsicles”) to see if areas near the head of constructed riffles had measurable differences in sediment size and geochemistry relative to riffle tails or pool positions. While Anne is sorry she wasn’t able to make it to Stuart’s talk (or AGU at all), she heard he did a great job. Just as she knew he would.
