Measurements of ice block samples in natural state using SQUID gradiometer for a JARE54-ASH1-2, b JARE54-ASH2-2 and c JARE54-ASH3-2. Black, red and blue symbols are magnetic field intensities in X, Y and Z axis, respectively. Each ice block sample is placed at zero position. Signal of blank tray filled with LN2 was subtracted
