The ESM project comprises eight Helmholtz Research Centers and aims at the development of a common Earth system modelling platform of the Helmholtz Research Field Earth and Environment in order to facilitate effective collaboration between partners and to support the development of a modelling strategy for POF-IV and beyond. The project intends to improve the numerical representation of the individual components of the Earth system and their coupling, as well as to perform a series of selected frontier simulations to address Grand Challenges.
Section Earth System Modelling is in particular engaged in Tasks 1.4 and 2.1.
The world ocean is good conductor of electricity, due to its high concentration of dissolved salts. As the electrically conducting seawater moves around the Earth, it permanently interacts with the ambient magnetic field generated in the Earth’s core. During this process, the positively and negatively charged salt-ions in the sea-water are deflected by the Lorentz force, which leads to spatial accumulation of electric charge and, in turn, weak electric currents in the entire ocean basin. These oceanic electric currents induce characteristic magnetic signals in the range of a few nanotesla (nT) that are mainly proportional to combined transports of water, heat, and salinity in the ocean.
The project aims at parametrising and validating a viscoelastic earth model for applications in earth-system models, which are applied in the national paleo climate modelling initiative PalMod (https://www.palmod.de/de). PalMod is funded by the Federal Ministry of Education and Science (BMBF) (http://www.bmbf.de/en/index.html) to understand climate system dynamics and variability during the last glacial cycle.
