Subglacial measurement of turbidity and electrical conductivity

  • Dan B. Stone (a1), Garry K. C. Clarke (a1) and Erik W. Blake (a1)

Abstract

Direct measurements of the properties of subglacial water are necessary for understanding water flow beneath glaciers. In this paper we describe the construction, calibration and field usage of two instruments—one that measures turbidity and the other that measures electrical conductivity of subglacial water. The sensors are inexpensive and reliable. To demonstrate the potential usefulness of these devices, we present samples of data obtained from beneath Trapridge Glacier, Yukon Territory, Canada.
