近年来，地震反射方法已成功地应用于海洋问题。在这里，我们提出了一种新的方法，将XBT和CTD测量与地震观测相结合，以可视化分辨率到几米的长剖面。对混合过程的全面研究面临的挑战是从数百公里到厘米的巨大空间尺度。传统的水文观测只能通过测量通常相隔几公里的离散位置的温度和盐度分布来解决大尺度影响，而专门的局部测量可以在空间光谱的另一端调查海洋的精细结构。相比之下，中间尺度很难系统地观察到。在这里，我们提供了覆盖中尺度的地震观测反演的温度和盐度数据，并提供了一种新的方法来成像中尺度过程，并允许以前所未有的分辨率研究它们的动力学。引用：Papenberg，C.，D.Klaeschen，G.Krahmann，和R.W.Hobbs(2010)，从水文和地震组合数据中反演海洋温度和盐度，地球物理。研究报告，37，L04601，DOI：10.1029/2009GL042115。
Recently seismic reflection methods have been successfully applied to oceanographic issues. Here, we present a new approach, combining XBT and CTD surveys with seismic observations, to visualize long sections with a resolution down to a few meters. The challenge to a full investigation of mixing processes has been the tremendous span of spatial scales ranging from hundreds of kilometers to centimeters. Traditional hydrographic observations could only resolve the large scale effects by measuring temperature and salinity profiles at discrete locations typically several kilometers apart, whereas dedicated localized measurements allowed investigation of the ocean fine structure at the other end of the spatial spectrum. The intermediate scales have in contrast been difficult to observe systematically. Here we present temperature and salinity data inverted from seismic observations that cover the intermediate scales and provide a new approach to image mesoscale processes and allow the investigation of their dynamics at unprecedented resolution.
