Coordinates of multichannel seismic line GeoB05-004

Major plastered drift sequences were imaged using high-resolution multichannel seismics during R/V Meteor cruises M63/1 and M75/3 south of the Mozambique Channel along the continental margin of Mozambique off the Limpopo River. Detailed seismic-stratigraphic analyses enabled the reconstruction of the onset and development of the modern, discontinuous, eddy-dominated Mozambique Current. Major drift sequences can first be identified during the Early Miocene. Consistent with earlier findings, a progressive northward shift of the depocenter indicates that, on a geological timescale, a steady but variable Mozambique Current existed from this time onward. It can furthermore be shown that, during the Early/Middle Miocene, a coast-parallel current was established off the Limpopo River as part of a lee eddy system driven by the Mozambique Current. […]

在莫桑比克海峡南部，沿林波波河沿岸的莫桑比克大陆边缘，R/V Meteor 航次 M63/1 和 M75/3 期间，利用高分辨率多通道地震学技术对主要漂移序列进行了成像。详细的地震地层学分析使得重建现代、不连续、涡旋主导的莫桑比克洋流的起始和发展成为可能。在早中新世时期，即可首次识别出主要漂移序列。与早期研究一致，沉积中心的持续北移表明，在地质时间尺度上，自那时起，莫桑比克洋流一直存在，且呈现出稳定但变化的特点。此外，还可证明，在早中新世至中中新世期间，作为由莫桑比克洋流驱动的背风涡流系统的一部分，林波波河附近形成了一条与海岸平行的洋流。 [...]
