Three seismic refraction profiles to measure crustal thickness and structure on transects along and perpendicular to the Kolbeinsey Ridge, north of Iceland: a 230 km line just east of the Kolbeinsey Ridge [Hooft et al., G-cubed, 2006], and 138 and 700 km cross-axis lines located 180 km [Furmall, UO MSc thesis, 2010] and 70 km north of the Icelandic coast [Brandsdottir et al, G-cubed, 2015]. The data were acquired using 33 three-component Japanese Ocean bottom seismometers (OBSs) from Hokkaido University. The seismic source of the University of Bergen research vessel, Håkon Mosby, was a four-element airgun array with a total volume of nearly 79 L (4800 cubic inch) towed at 8 m depth.
