海洋科学学术讲座预告第489期：Planetary Geoscience to Marine Sciences: Current Research and Future Directions

Advances in planetary geoscience enable high-resolution mapping of surface composition through hyperspectral remote sensing, spectroscopy, and data-driven modeling, providing insights into past aqueous environments on Mars. Integrating mineralogical mapping, geochemical–thermodynamic modeling, and machine learning–based prediction from spectral, XRD, and XRF data offers a robust framework for interpreting complex depositional systems.

These approaches are transferable to marine environments, where sediment heterogeneity and diagenesis remain challenging. Combining AI with multisource data fusion links spectral signatures to geochemical proxies, improving interpretations of marine sediments and variability. Coupling these with satellite observations enables investigation of subsurface–surface interactions and marine heatwaves.

Extending these methods to ocean worlds and Mars provides new pathways to reconstruct past aqueous activity and advance predictive understanding across planetary and marine systems.
