Surface melt‐driven seasonal behaviour (englacial and subglacial) from a soft‐bedded temperate glacier recorded by in situ wireless probes. Earth Surface Processes and Landforms, 44(9), pp.1769-1782. Methods for processing the data: Water pressure data was calibrated in the field to measured water levels in the boreholes after deployment, and on subsequent field days.The Water pressure is converted to meters water eqquilent and then devided by the glacier depth (measured by ground penetrating radar and GPS - see Hart, J.K., Rose, K.C., Clayton, A. and Martinez, K., 2015. Englacial and subglacial water flow at Skálafellsjökull, Iceland derived from ground penetrating radar, in situ Glacsweb probe and borehole water level measurements. Earth Surface Processes and Landforms, 40(15), pp.2071-2083.) Effective pressure = ice overburden pressure minus water pressure.
