Sediment electric conductivity profiles of benthic EM profiler NERIDIS during HEINCKE cruise HE537, profile HE537_82NE_P3

Sediment-physical properties of the seabed mapped with the MARUM benthic EM profiler NERIDIS III during HEINCKE cruise HE537. The profiler was towed in contact with the seabed at speeds of 2-4 kn (1-2 m/s) along 11 parallel, 2.5 km long survey lines with 50 m line-spacing at salt diapir Berta. A half-space inversion method (Müller et al., 2012) was used to convert 75 Hz and 10 kHz inphase and quadrature data into apparent electric conductivity and magnetic susceptibility of the shallow subsurface (approx. 0-1 m below seafloor).

在HEINCKE巡航HE537期间，利用MARUM海底生物电磁剖面仪NERIDIS III，对位于盐丘贝塔处的海床沉积物的物理性质进行了测绘。该剖面仪以2-4节（1-2米/秒）的速度在海床上进行拖曳，沿11条平行、长度为2.5公里的测线进行作业，测线间距为50米。采用半空间反演法（Müller等，2012年）将75赫兹和10千赫兹的相位和正交数据转换为浅层地下（约海平面以下0-1米）的视电导率和磁化率。
