观测海洋的空间和时间动态是了解全球和区域水混合情况的基础。物理海洋学传统上是通过现场测量来观察海洋结构，其时间和/或空间分辨率往往有限。在勘探地震学中，过去几十年来开发了一套技术，通过高水平分辨率的反演方法对海底下结构的物理特性进行成像和定性。这两个不同的领域在地震海洋学中产生了联系，发展成熟的海洋反射地震学方法被应用于动力海洋。然而，一个方面，到目前为止，在地震海洋学中被忽视的是动态的，随时间变化的性质的水结构。在这里，我们表明，它是可能的，以估计时间变化的反射在水结构作为反演参数。新的动力学特性反射层运动速度提供了表征海洋水动力学的额外参数。引文：Klaeschen，D.，R.

The observation of spatial and temporal dynamics of the ocean is fundamental to understand global and regional aspects of water mixing. Physical oceanography has traditionally observed ocean structures with in situ measurements, often limited in temporal and/or spatial resolution. In exploration seismology a set of techniques has been developed over the last decades to image and characterize the physical properties of sub-seafloor structures by inversion methods at high horizontal resolution. The two different fields have made contact in seismic oceanography where the well developed methods of marine reflection seismology have been applied to the dynamic ocean. However, one aspect, so far ignored in seismic oceanography, is the dynamical, temporally varying nature of water structures. Here we show that it is possible to estimate temporal variations of reflectors in water structures as an inversion parameter. The new dynamic property reflector movement velocity gives an additional parameter to characterize ocean water dynamics. Citation: Klaeschen, D., R. W. Hobbs, G. Krahmann, C. Papenberg, and E.
