摘要：Understanding geological and hydrogeological characteristics in coastal areas is an issue of paramount importance considering its socio-economic relevance, whereas, to date, limited information has been acquired due to the lack of suitable survey methods.We have conducted an airborne electromagnetic survey in an alluvial coastal plain, Kujukuri, in southeast Japan, to examine the effectiveness of elucidating the subsurface electric-resistivity structure both on land and offshore.Our approach was to use a grounded electrical dipole source and a helicopter-towed magnetic field receiver.Repeated surveys both at high and low tides revealed that a reliable resistivity structure is available to a depth of 300–350 m in coastal areas where shallow (∼5 m deep) water prevails. Key words Airborne electromagnetics resistivity coastal area Kujukuri.
