The remaining fixed GCPs were mounted around the central glacier forefiel of Jamtalferner. By using an Differential GPS the exact locations of the GCPs were measured with an accuracy of a few centimeters. High snow melt rates have melted almost all snow in the area of interest and increased the runoff considerably up to more than 6m³/s. Thus, we have started the discharge calibration measurements using the salt dilution method.
