Underwater imaging generates large volumes of observational data, but converting these images into reliable, structured scientific observations remains challenging. This is particularly true for benthic organisms that retreat into the sediment when disturbed. The razor clam Ensis provides a representative case, as individuals can rapidly burrow, making direct surveys difficult and potentially...

The location of ice impurities in its microscopic structure, particularly within its grain boundaries, significantly affects the preservation of climatic signals and the deformation behaviour of ice. Ice-impurity interactions also influence the microstructure of ice crystals. Understanding this interplay is highly relevant to interpretations of ice-core records and our understanding of climate...

Modern sensors and analytical methods produce data at higher spatial and temporal resolution while adding new variables, data types, and processing steps. This is particularly evident in geosciences, where information from different locations, instruments, sampling campaigns, and analytical workflows needs to be considered together. The central challenge is therefore no longer a lack of data,...

Machine learning is reshaping how we simulate the Earth system: data-driven weather models now rival operational forecasts at a fraction of their cost. Whether the same holds for the ocean is far less clear, as it is a slowly evolving, strongly forced component whose simulations have to stay stable far beyond weather forecast horizons. At GEOMAR we follow two complementary routes to...

Machine learning is reshaping how we simulate the Earth system, and data-driven emulators of the ocean and sea ice are becoming stable and skillful. Yet purely data-driven models lack physical interpretability with respect to individual dynamical and thermodynamic processes, and their generalizability to a changing climate remains uncertain. At GEOMAR we therefore also follow a second,...

Research today rarely stays within one institution, one dataset, or one infrastructure.
