 note = {P(論文), 第30次南極地域観測において, 船上地磁気3成分磁力計による地磁気3成分測定およびプロトン磁力計による地磁気全磁力測定の同時観測を行った。プロトン磁力計の全磁力測定から船速の違いによるノイズの変化が見られた。このノイズの変化は, 船速が速くなりセンサーが不安定になることによって引き起こされたと考えられる。船上地磁気3成分測定からは, 船の船首方位の細かな揺動による短波長のノイズが見られた。船上地磁気3成分測定によって得られた地磁気3成分のデータに, プロトン磁力計によって得られた全磁力の結果をうまく適合することによって, 地磁気3成分のデータの絶対値に関してより信頼度の高いデータが得られた。現段階では, 地磁気3成分のデータの絶対値に関する問題を扱う場合プロトン磁力計との同時観測が必要である。以上の結果をもとに, 今後の海上における地磁気測定の改善が望まれる。, Three components and total intensity of the geomagnetic field were measured by STCM (Shipboard Three Components Magnetometer) and a proton magentometer at the same time at sea during the 30th Japanese Antarctic Research Expedition. The measurements of total intensity of the geomagnetic field by a proton magnetometer showed a variation of noises in harmony with the variation of ship's velocity. This variation of noises may be caused by instability of the sensor due to large velocity of the ship. The measurements of three components of the geomagnetic field by STCM revealed short wavelength noiscs which were caused by small yawing of the ship. Reliable absolute values of three components of the geomagnetic field were obtained by adapting the total intensity of the geomagnetic field measured by a proton magnetometer to the data of three components of the geomagnetic field measured by STCM. In the present state of STCM, it is necessary to measure three components and total intensity of geomagnetic field by STCM and a proton magnetometer simultaneously, in case of obtaining the absolute values of three components of the geomagnetic field. These results suggest that improvement of measurement of the geomagnetic field at sea will be required.},
