Ocean signals in Earth's magnetic field (OceanMag-II)

由于它们储存（和释放）大量热量的能力，世界海洋是地球气候系统的重要组成部分。此外，海洋中储存的盐使它们成为良好的导电体。特征电磁（EM）信号是结果。传统上，海洋潮汐和海洋环流的电磁信号是分开研究的。这两种信号对海洋的不同物理特性都很敏感。海洋环流的EM异常主要来源于海速变化，而EM海洋潮汐异常主要是由海温变化引起的。在建议的项目中，我们的目标是同时使用潮汐和环流电磁观测，即，以获取海洋的信息。对全球环流信号进行了表征和同化。在这个提案（oceanmagi - ii）中，我们想要表征和吸收海洋潮汐信号。最后，我们的目标是两个系统的联合版本。在整个项目中，研究结果将根据独立的、部分基于代理的观察结果进行验证。

Due to their ability to store (and release) large amounts of heat, theworld oceans are a crucial part of Earth's climate system. Inaddition, the oceans store salt which makes them a good electricconductor. Characteristic electromagnetic (EM) signals are the result.Traditionally, EM signals from ocean tides and ocean circulation arestudied separately. Both signals are sensitive to different physicalproperties of the oceans. While the EM anomalies of the oceancirculation originate in ocean velocity changes, the EM ocean tideanomalies are dominated by ocean temperature changes. In the proposedproject we aim to use tidal and circulatory EM observations together,i.e., synergetically, to derive information of the ocean. Globalcirculation signals were characterized and assimilated duringOceanMag-I. In this proposal (OceanMag-II) we want to characterize andassimilate the ocean tidal signals. In the end we aim for a jointinversion of both systems. Throughout the project, findings will bevalidated against independent, in parts proxy-based observations.
