      Microtopographic controls on ecosystem functioning in the Arctic Coastal Plain

      D. Zona, D. A. Lipson, R. C. Zulueta, S. F. Oberbauer and W. C. Oechel

      Article first published online: 27 JUL 2011 | DOI: 10.1029/2009JG001241

      Key Points

      • Microtopographic gradient led to pattern in pH, EC, ORP, and dissolved CO2
      • Microtopography controls lateral flow of organic matter and litter accumulation
      • Low-centers polygons have highest pH, ER, and dissolved CO2
