海洋磁力测量空间归算阈值条件确定及其应用

Application and Determination of Threshold on Free-Air Correction of Marine Magnetic Survey

  • 摘要: 对仿真和实测数据的空间变化进行了分析,得出拖鱼起伏高度变化对测量成果的影响量级与测区磁异常水平梯度变化的复杂程度有关。提出了归算的阈值条件,并通过实例验证了该条件的合理性与实用性,并提出当测区要求是一级、二级和三级测量精度时,必须将测量数据归算到平均海面上。

     

    Abstract: Space variation of simulation and practical data are analyzed.The conclusions show that the influence of fish's height change to surveying results is relate with complexity of horizontal gradient of magnetic anomaly.Based on foregoing analysis,threshold is proposed,and rationality and practicability are proved by test data.We suggest that magnetic survey data must be corrected to mean sea level when carry level 1,level 2 and level 3 marine magnetic survey.
