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 Baltic Sea contains an estimated 300,000 tons of unexploded ordnance (UXO), presenting ongoing environmental and safety challenges.

While multibeam echosounder (MBES) surveys are the standard for detecting these hazards due to their high positional accuracy, the acoustic signatures of munitions often resemble geological features or debris, necessitating manual visual verification.

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,...

Laboratory-scale rotating-tank experiments are used for demonstration purposes and for investigating scaling laws in geophysical fluid dynamics. Quantitative studies using affordable outreach-focused rotating tank setups are challenging and usually depend on manual measurements and narrative-based protocols prepared by the exerimenters. This talk outlines a processing pipeline for videos of a...

We present our work on the latest version of AWIs Database of AI-detected Retrogressive Thaw Slumps (DARTS) using a pan-arctic coverage from Sentinel-2 Quarterly Mosaics (~20 Mio km² annually) and auxiliary data sources. Retrogressive Thaw Slumps (RTS) are abrupt disturbances in ice-rich permafrost that dramatically change topography, hydrology, biogeochemistry, and local ecosystems by...

The Alfred Wegener Institute has accumulated a large and heterogeneous body of marine and polar observation data including multi-decadal time series from long-term observatories, passive acoustic recordings, environmental DNA sequencing, and seafloor imagery.

We use AI to turn this data into knowledge. For example, we use detection models to extract different types of whale call events from... -

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,...

Foodwebs, as interaction networks of species, are fundamental to understanding ecosystem function. To date, their complex structure and dynamics have been the subject of intensive research. However, most studies have focused on specific properties such as degree distributions, connectance, or species traits in order to identify universal patterns across foodwebs. Holistic investigations that...

Scientific decision-making in complex systems requires interactive systems, such as digital twins, that can combine domain knowledge, data-intensive workflows, and transparent computational methods. We present an approach for building AI agents that support well-grounded, data-based decisions by embedding conversational capabilities directly into scientific web applications. The approach...
