PROCESSING AND ANALYSES ON SHIPBOARD THREE-COMPONENT MAGNETOMETER DATA FROM PRYDZ BAY, ANTARCTICA
摘要
Abstract
A Shipboard Three-Component Magnetometer (STCM) is easily deployed, unrestricted in its use, and capable of multiparameter measurements, which are clear advantages compared with a towed magnetometer in harsh polar environments. In this paper, we analyze the influences of a ship's magnetic field on the STCM data acquired during the 29th Chinese Antarctic Research Expedition, and obtain the corrected magnetic signature and its corresponding scalar geomagnetic field. Comparison with data acquired from a towed magnetometer, there is 47.56 nT of standard deviation for the STCM data, reflecting the tolerable performance, reliability, and high quality of data of an STCM in polar regions. This constitutes the first-time for Chinese researchers to testify the STCM measurement available in polar seas. Related technical refinements will provide effective support for the acquisition of STCM data in upcoming Chinese polar expeditions.关键词
