Gully formation in the McMurdo Dry Valleys, Antarctica: multiple sources of water, temporal sequence and relative importance in gully erosion and deposition processes

Flow advance in Gully A and pond generation on the floor of South Fork during the end of austral summer (February/March), 2010. Noise/static patterns are due to low signal reaching the sensor during night-time conditions late in austral summer. Vantage point shown in Figure 4a (Site 1).
