An ocean bottom magnetometer was installed in Breid Bay and was successfully retrieved during the 29th Japanese Antarctic Research Expedition (JARE-29). The seafloor geomagnetic observation provided a time series of the three-component geomagnetic field once every minute and this time series continues as long as 36 days. The data obtained were analyzed by spectral analysis methods and compared with the simultaneous data obtained at Syowa Station. The obtained data proved almost satisfactory except for some instrumental limitations such as a lack of a geographical compass equipped with the magnetometer. The result reveals the effectiveness of an ocean bottom magnetometer as a temporal geomagnetic station even in such a logistically difficult region as Antarctica.
