Descr: Title: "Detection and attribution of changes in the hydrologic regimes of the Mackenzie, the Kuparuk, and the Lena Rivers Short description of project: Our project seeks to understand changes in freshwater storage elements in the Arctic over the past 100 years. We are studying rivers, lakes, soil moisture, groundwater, aufeis, pingos, snow, and glaciers. McCall Glacier in the Brooks Range has the longest history of scientific research of any US Arctic glacier, and our program has chosen it as our primary glacier study site in the Arctic. In order to properly interpret the connection between climate and ice volumes, we must understand the flow processes of this polythermal glacier. Passive seismics offer one way to do that by helping us understand the timing and location of motion events. We will have concurrent GPS measurements of position at several locations, and passive seismics will make a nice complement to this.
