[ { "title": "Towards an AI enabled forest systems platform", "url": "/submissions/117", "abstract": "<p>\n In forestry, having consistently relevant and correct information is critical towards environmentally conscionable decision making. Consulting commercially available or open-source Large Language Models (LLMs) in this decision-making process can be an effective way towards informed decision making. However, currently LLMs have demonstrated to be deficient in three critical areas: reliable information sources, lack of access to real world data, and ambiguity in their scientific reasoning ability.\n</p>\n<p>\n To overcome these shortcomings we opted to instantiate a curated knowledgebase containing information from relevant CC-0 research articles. With clearly defined constraints applied to each research article intended for ingestion in the knowledgebase, it becomes possible for the underlying LLM to produce feedback that is correct, concise and accurate. Some of the constraints of the knowledgebase are in place to adhere to European laws regarding the ethical use of AI as well as comply with copyright laws.\n</p>\n<p>\n Aside from having access to relevant research papers, having access to real world data is one of the cornerstones of the proposed framework. By utilizing calibrated level 1 data from multiple sensors, platforms and measuring devices, we can implement agentic RAG functionality to retrieve information about our area of interest.\n</p>\n<p>\n Lastly, reasoning abilities in Large Language Models (LLMs) are paramount and are considered an area of continuous research. While in the current state of the art LLMs convey a form of thinking or reasoning process, its efficacy is still hotly debated. In this research, the focus is on a more comprehensive and explainable scientific reasoning framework involving a decision-making AI agent. Wherein the AI agent will have to determine the goal of an input query, devise a logical methodology to resolve that goal, and execute the resolution using an array of pre-defined actions.\n</p>\n<p>\n This system has the potential to not only provide the end user with real world data but also provide deeper insights from scientific articles, derive scientific reasoning, as well as assist the user in decision making processes.\n</p>\n", "presentation_type": "Digital Poster/Demo", "session": "Postersession No. 1", "start": "2025-09-03T15:45:00+02:00", "duration": "00:45:00", "authors": [ { "author": { "first_name": "stephan", "last_name": "playfair", "orcid": null }, "affiliation": [ "Hochschule für Nachhaltiche Entwicklung Eberswalde", "Leibniz-Zentrum für Agrarlandschaftsforschung (ZALF)" ], "is_presenter": true } ], "submitter": "stephan playfair", "event": "Data Science Symposium 2025", "activity": "AK Portal & Viewer Technologies (Viewer)", "accepted": true, "license": "Creative Commons Zero v1.0 Universal (CC0-1.0)", "affiliations": [ "Hochschule für Nachhaltiche Entwicklung Eberswalde", "Leibniz-Zentrum für Agrarlandschaftsforschung (ZALF)" ] }, { "title": "Different Portals - Different Views on the Same Content", "url": "/submissions/106", "abstract": "<p>\n The proliferation of digital portals for accessing environmental and geoscientific data has significantly enhanced the ability of researchers, policymakers, and the public to retrieve and utilize critical information.\n</p>\n<p>\n Furthermore, metadata content can be harvested, which brings the added value that information is collected only once and then presented in different web presences.

Persistent Identifiers (PIDs) in metadata enable the reuse of common information from shared sources. Broad adoption of PID types enhances interoperability and supports machine-actionable data.

However, even in the era of analog photo albums, metadata was added to images to preserve their context for the future. Today, the marine community wants to analyze far larger datasets of videos and images using computers, which generally cannot easily understand the image content on their own. Therefore, researchers have to record the content and context of images in a structured format to enable automated, systematic and quantitative image analysis.\n</p>\n<p>\n The metadata file format FAIR Digital Objects for images (iFDOs) provides this structure for describing individual images and hole datasets. iFDOs primarily structure the answers to the five W's and H questions: Where were the images taken, by whom, why, when, how, and what is actually shown in the images or videos. Together, these pieces of information provide FAIRness (findability, accessibility, interoperability and reusability) to datasets.\n</p>\n<p>\n Researchers benefit from iFDO enhanced datasets, as they already provide the information necessary for data homogenization, enabling machine learning applications and mass-data-analysis. Data viewers and portals, such as\n <a href=\"https://marine-data.de\" rel=\"noopener noreferrer\" target=\"_blank\">\n marine-data.de\n </a>\n , can increase the reach and impact of datasets by visualizing the datasets and making them findable using the context and content information given by iFDOs. For this to work, the data must first be published in FAIR data repositories such as\n <a href=\"https://pangaea.de/\" rel=\"noopener noreferrer\" target=\"_blank\">\n PANGAEA\n </a>\n . However, the data repositories also benefit from iFDOs, as they can use metadata from the iFDO to simplify or even automate parts of the submission process saving time for the curators and researchers.\n</p>\n<p>\n Although the image datasets and their iFDO files could be created manually, our aim is to automate the process as much as possible, while also integrating existing metadata sources, such as the\n <a href=\"https://registry.o2a-data.de/\" rel=\"noopener noreferrer\" target=\"_blank\">\n O2A Registry\n </a>\n and the\n <a href=\"https://extract.dship.awi.de/insightics/\" rel=\"noopener noreferrer\" target=\"_blank\">\n DSHIP land system\n </a>\n .

As a result, data literacy has become a key element for researchers from all domains. Additionally, interdisciplinary, multidisciplinary, and collaborative approaches are more essential now than ever before. The Rhine-Ruhr Center for Scientific Data Literacy (DKZ.2R) focuses on a combined methodological data literacy, integrating data science and machine learning skills, high performance computing and research data management competencies. Our main objective is to promote a holistic data literacy offering support for researchers in the form of trainings, consultings, data challenges and tools for data analysis and management.\n</p>\n<p>\n The availability of ever larger and more complex amounts of data requires comprehensive and methodological skills that researchers must often learn independently. These skills begin with the consideration of how scientific data should be collected, extending to questions about data processing applications, methods, infrastructure, and finally, publishing.

Public data sources like Common Crawl contain significant noise, creating a bottleneck for developing specialized models. We address this by presenting a complete HPC workflow that enables researchers to curate web-scale text data and measure the impact on model performance.\n</p>\n<p>\n Our workflow equips users to process a 230 GB, 89-million-document German dataset from Common Crawl. Users analyze pre-computed quality signals, design custom filters to remove low-quality content, and execute a pipeline that automates data preparation. This pipeline handles metadata removal, data merging, indexing, and tokenization. It integrates the modalities framework for distributed training on GPUs and uses poetry for environment management, making the HPC operations reproducible.\n</p>\n<p>\n We will apply this workflow as an interactive data challenge in which the participants are presented with a specific task:\n <br/>\n - Start with the 89 million raw documents and their quality signals.\n <br/>\n - Design a filter that selects a high-quality subset of approximately 20 million documents, aiming to remove around 80% of the original data.\n <br/>\n - Execute the automated HPC pipeline to process the filtered subset.\n <br/>\n - Train a large language model (LLM) on the curated data and evaluate it to achieve a performance score on the Hellaswag benchmark that exceeds our random-sampling baseline.\n</p>\n<p>\n This demonstration offers a tangible blueprint for data-centric AI projects.

Traditional morphodynamic models often face challenges in capturing these dynamics, particularly in regions like the Wadden Sea, where the feedback mechanisms between physical processes and seabed changes are highly intricate. In this study, we explore the potential of deep learning techniques to address these limitations, using convolutional neural networks (CNN) for bathymetric reconstruction and convolutional long short-term memory (ConvLSTM) networks for forecasting. We applied these models to a dataset of bathymetric observations from the German Bight, which provides detailed coverage of the seabed from 1983 to 2012. First, we demonstrated that CNN effectively reconstructs spatial bathymetric patterns based on incomplete data inputs, achieving accurate reproductions of observed bathymetry with minimal reconstruction error, particularly in regions with active dynamics like tidal channels. Second, we used ConvLSTM for forecasting, training the model with past observations to predict bathymetry. The ConvLSTM model performed well, with an area-averaged root mean square error of 0.139 m. Our results indicate that deep learning techniques offer promising alternatives to traditional methods for both spatial reconstruction and forecasting of bathymetric changes. These models can improve predictions of seabed dynamics, which are critical for effective coastal management, navigation, and environmental protection.\n</p>\n", "presentation_type": "Poster", "session": "Postersession No. 1", "start": "2025-09-03T15:45:00+02:00", "duration": "00:45:00", "authors": [ { "author": { "first_name": "Irem", "last_name": "Yildiz", "orcid": null }, "affiliation": [ "Helmholtz-Zentrum Hereon" ], "is_presenter": true }, { "author": { "first_name": "Emil V.", "last_name": "Stanev", "orcid": null }, "affiliation": [ "Helmholtz-Zentrum Hereon" ], "is_presenter": false }, { "author": { "first_name": "Joanna", "last_name": "Staneva", "orcid": null }, "affiliation": [ "Helmholtz-Zentrum Hereon" ], "is_presenter": false } ], "submitter": "Irem Yildiz", "event": "Data Science Symposium 2025", "activity": null, "accepted": true, "license": "Creative Commons Attribution 4.0 International (CC-BY-4.0)", "affiliations": [ "Helmholtz-Zentrum Hereon" ] }, { "title": "AqQua The Aquatic Life Foundation Project: Quantifying Life at Scale in a Changing World", "url": "/submissions/84", "abstract": "<p>\n Aquatic life is crucial for human well-being, playing a key role in carbon sequestration, climate regulation, biodiversity conservation and nutrition. Plankton are the basis of aquatic food webs and sustainably sequester vast amounts of carbon from the atmosphere to the ocean’s interior. Impacts of climate change and pollution on plankton functioning and diversity not only impact fish resources that play a major role in human nutrition, but also the efficiency of the biological carbon pump. The critical role of aquatic life in biogeochemical cycles, climate regulation, conservation of aquatic biodiversity and human nutrition mandates precise mapping and monitoring. Distributed pelagic imaging techniques enable comprehensive global observation, providing critical insights for decision-making and carbon dioxide removal strategies. To this end, each day, millions of images of plankton and particles are taken by researchers around the globe, using a variety of imaging systems. Each individual image and its associated metadata can provide crucial information not only about the individual organism or particle, but also on the biodiversity and functioning of aquatic food webs, ecosystem status of the related water body, and its role in carbon sequestration. The Aquatic Life Foundation Project will, for the first time, combine billions of images acquired with a variety of devices across the globe. We will leverage this dataset for large-scale training of a foundational pelagic imaging model, which we will fine-tune for the highly relevant down-stream tasks of species classification, trait extraction and particulate organic carbon estimation. We will exploit model predictions to establish global maps of species biodiversity, ecosystem status, and carbon flux at unprecedented accuracy and granularity, thereby generating\n</p>\n", "presentation_type": "Poster", "session": "Postersession No. 1", "start": "2025-09-03T15:45:00+02:00", "duration": "00:45:00", "authors": [ { "author": { "first_name": "Ankita", "last_name": "Vaswani", "orcid": null }, "affiliation": [ "Helmholtz-Zentrum Hereon" ], "is_presenter": true }, { "author": { "first_name": "Christina", "last_name": "Hübers", "orcid": null }, "affiliation": [ "Max Delbrück Center for Molecular Medicine in the Helmholtz Association (MDC), Helmholtz Imaging" ], "is_presenter": false }, { "author": { "first_name": "Dagmar", "last_name": "Kainmüller", "orcid": null }, "affiliation": [ "Max Delbrück Center for Molecular Medicine in the Helmholtz Association (MDC), Helmholtz Imaging" ], "is_presenter": false }, { "author": { "first_name": "Klas Ove", "last_name": "Möller", "orcid": null }, "affiliation": [ "Helmholtz-Zentrum Hereon" ], "is_presenter": false }, { "author": { "first_name": "Lisa", "last_name": "Mais", "orcid": null }, "affiliation": [ "Max Delbrück Center for Molecular Medicine in the Helmholtz Association (MDC), Helmholtz Imaging" ], "is_presenter": false }, { "author": { "first_name": "Martin", "last_name": "Schröder", "orcid": null }, "affiliation": [ "GEOMAR Helmholtz-Zentrum für Ozeanforschung Kiel" ], "is_presenter": false }, { "author": { "first_name": "Peter", "last_name": "Hirsch", "orcid": null }, "affiliation": [ "Max Delbrück Center for Molecular Medicine in the Helmholtz Association (MDC), Helmholtz Imaging" ], "is_presenter": false }, { "author": { "first_name": "Rainer", "last_name": "Kiko", "orcid": null }, "affiliation": [ "GEOMAR Helmholtz-Zentrum für Ozeanforschung Kiel" ], "is_presenter": false } ], "submitter": "Ankita Vaswani", "event": "Data Science Symposium 2025", "activity": null, "accepted": true, "license": "Creative Commons Attribution Non Commercial 4.0 International (CC-BY-NC-4.0)", "affiliations": [ "Helmholtz-Zentrum Hereon", "Max Delbrück Center for Molecular Medicine in the Helmholtz Association (MDC), Helmholtz Imaging", "GEOMAR Helmholtz-Zentrum für Ozeanforschung Kiel" ] }, { "title": "YOLO at Your Fingertips: Object Detection without Coding", "url": "/submissions/113", "abstract": "<p>\n Image-based data analysis is becoming increasingly important in Earth and environmental sciences – for example, in marine biodiversity monitoring, drone image evaluation, or automated habitat classification.
