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，海洋储存盐分，这使它们成为良好的导电体。传统上，海潮电磁信号和海洋环流电磁信号是分开研究的。这两种信号对海洋的不同物理性质都很敏感。大洋环流的EM异常起源于海速变化，而EM海洋潮汐异常主要受海洋温度变化的影响。在拟议的项目中，我们的目标是同时使用潮汐和环流电磁观测，即协同获取海洋信息。在海洋MAG-I期间，全球环流信号被表征和同化。在这项建议(海洋大气层二号)中，我们想要描述和吸收海洋潮汐信号。最后，我们的目标是两个系统的联合反转。在整个项目中，调查结果将与独立的、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.
