Javier Lapazaran and Jaime Otero, with the collaboration of the polish researcher Darek Puzcko, developed the Arctic campaign of spring (April) 2009. This campaign focused on ground-penetrating radar (GPR) studies on Hansbreen and Ariebreen glaciers, as well as Amundsenisen icefield, all of them located within a radius of 40 km from the Polish Polar Station at Hornsund, southern Spitsbergen, Svalbard, which provided the logistic support to our fieldwork. Part of the GPR profiles done during this campaign were complementary to earlier ones done by the polish research teams lead by Jazek Jania and Piotr Glowacki. On Hansbreen, we did GPR profiles at 25 MHz, and succeeded in determining the ice thickness of the thickest ice (>300 m), in areas where bedrock could not be reached in earlier campaigns by the polish team. On Ariebreen we did common midpoint (CMP) measurements aimed at determining the radio-wave velocity in ice. On Amundsenisen we did 25 and 100 MHz GPR profiling, focused on determining the extent and thickness of the cold ice layer.
