Fig. 12From: Environmental and anthropogenic gravity contributions at the Þeistareykir geothermal field, North IcelandInstrumental drift correction for the three iGravs at Þeistareykir by comparison to FG5#206 absolute measurements in summers 2018, 2019 and 2020 (red dots with error bars); drift corrected iGrav residuals shown with dark shaded colours (dark blue, dark green and purple); enlarged section shows initial exponential drift that was removed in iGrav006 residualsBack to article page
