Short summary of your group's research: We apply numerous geophysical methods to understand sub-seafloor processes for tectonic, environmental and resource questions. Our expertise involves not only the evaluation of the individual methods / datasets, but has recently evolved into the application of state-of-the-art machine learning workflows to integrate disparate geophysical and geological data on various spatial scales.

What infrastructure, programs and tools are used in your group? 

HPC Computing Centres at CAU Kiel
Open-source programms for interpreting Electromagnetic data
Python tools for ML

What could a participant of the HIDA Trainee Network learn in your group? How could he or she support you in your group? We are seeking for guest researchers with various geophysical data (e.g. CSEM, Seismics and Borehole Data) seeking to develop new concepts on integrating these into a consistent subsurface model.

Short summary of your group's research: The Oceanic Machine Vision Group at the GEOMAR works on the topic of optical underwater surveys employing artificial intelligence (AI) and classical computer vision approaches. To this end, we seek to enable cameras to serve as faithful measurement instruments and navigation sensors in the deep sea. The latter, visually challenging environment, presents us with a lot of geometric (refraction) and radiometric problems (attenuation, scattering) which we seek to solve.

What infrastructure, programs and tools are used in your group? We normally devise novel approaches writing Python / C++ Code on Linux machines storing it on GIT, potentially in some remote (over ssh) work. If desired, access to GPUs can be provided in addition.

The subsequent evaluation is often conducted on synthetic as well as real data. To this end, we maintain multiple sets of underwater imagery, specifically tailored to the problems we work on. We also have camera-light systems, which can be operated manually, inside a test tank or directly in the Baltic Sea. In addition, they can be attached to AUVs and the like, to capture actual deep sea datasets. Hence, new data can be taken, if necessary.

What could a participant of the HIDA Trainee Network learn in your group? How could he or she support you in your group? The guest can learn about synthesizing visual data or taking real data in controlled conditions in a test tank, or at the actual sea. Furthermore, we can provide deep insights about geometric and radiometric problems typically encountered in underwater scenarios. We have a wide range of topics inter alia covering refraction, color correction, medium estimation, light pose optimization, structure from motion, state estimation and image segmentation/classification. We will approach those problems with the means of classical computer vision but also with neural networks in conjunction with differentiable physical models. Finally, we would be happy if the guest researcher would co-author a research paper and/or contribute to our software.

Three-sentence summary of your group's research: The Data Science Unit (DSU) of GEOMAR develops Data Science methods for marine research and applies them together with the researchers to the heterogeneous data of GEOMAR and its partner institutes. The DSU offers support and training on Data Science methods to researchers at GEOMAR. We aim to adress the grand challenges of marine science with data science methods.

What infrastructure, programs and tools are used in your group? We work with all data types relevant to the marine sciences: time series (e.g. in climate research, ecology), grids (e.g. in seafloor mapping, microscopy imagery), cubes (e.g. in ocean current simulation, 4D visualization). Our data products are developed and operated interactively (e.g. Jupyter notebooks) and most of the magic happens in Python. High-performance computing can be conducted on HGF computing ressources, at our compute cluster at Kiel University or on mobile GPU clusters for HPC computing at sea.

What could a guest researcher learn in your group? How could he or she support you in your group? Working with marine science data sets. Detecting and classifiying events in heterogeneous data (time series, grids, data cubes, ...). AI and ML methods. Supervised / unsupervised clustering of data. Integration of AI, simulation, and observation methods and data into Digital Twin frameworks. Working towards solutions for pressing ocean and society challenges.

Three-sentence summary of your group's research: Our laboratory conducts research on single-celled organisms known as bacteria and archaea that have a crucial role in the cycling of (micro)nutrients in both the photic and aphotic regions of the global oceans. Our research in the field of biological oceanography encompasses the integration of marine microbial ecology and biogeochemistry, operating under the overarching framework of physical oceanography. At GEOMAR, our research focuses on investigating microbial B vitamins, ectoenzymes, and the functional capabilities of microorganisms. We employ integrated multi-omics approaches, together with laboratory studies conducted at the Boknis Eck Time-Series Station in the Southwest Baltic Sea and during oceanographic cruises.

What infrastructure, programs and tools are used in your group? State-of-the-art molecular tools are employed in our lab facilities to conduct experiments involving these organisms. These tools include e-DNA analysis, molecular laboratory techniques, flow cytometry, microscopy, and the use of genetically modified organisms (GMOs). Metagenomic, -transcriptomic, and -proteomic analyses generate a vast amount of data, which can be effectively analyzed by leveraging the high-performance computing cluster available at Kiel University. The analysis of Underwater Vision Profiler (UVP) images is presently conducted using the Quantitative Imagery Platform of Villefranche.

What could a guest researcher learn in your group? How could he or she support you in your group? The visiting scientist will have the opportunity to actively participate in ongoing research and gain knowledge regarding the bioinformatic analysis of multi-omic and e-DNA datasets. In summary, this encompasses the implementation of essential software, the development of procedural frameworks, computational methodologies for data-driven microbiology, and the utilization of visualization techniques.
