标题： Magnetic imaging of shipwrecks

摘要： 船舶沉船中的铁磁性材料会对地球磁场造成影响，这种影响可以在地表测量到。 地表的质子磁力计测量用于定位沉船。 在这里，我讨论如何解释这些数据以探索沉船在海底的形状和方向。 我详细说明了如何建模沉船并推导出 resulting 的磁信号。 我也讨论了如何以更一般的方式分析数据。 作为例子，我展示了并分析了关于以下沉船的数据： YSTROOM 和 BOUBOULINA（原 COLONEL LAMB）。 显示英文摘要

摘要： The ferromagnetic material in a shipwreck on the seabed causes a modification to the earth's magnetic field which can be measured at the surface. Proton magnetometer measurements at the surface are used to locate wrecks. Here I discuss how to interpret such data to explore the shape and orientation of the shipwreck on the seabed. I give details of how to model shipwrecks and deduce the magnetic signal that results. I also discuss how to analyse data in a more general way. As examples, I present and analyse data on the shipwrecks of YSTROOM and BOUBOULINA (ex COLONEL LAMB).
