The framework takes as input a set of geographical features at a specified grid resolution (e.g., 5 arc-minute scale) and corresponding point measurements with their spatial coordinates and target values. The framework trains and evaluates multiple machine learning models, including both tree-based methods (Random Forest, XGBoost, CatBoost) and deep learning architectures (feed forward neural networks, TabPFN[1]), to identify the optimal predictive model for the given dataset.\n <br/>\n The framework incorporates hyperparameter search(depth and width) for deep learning models and systematic parameter search for tree-based models (e.g., number of estimators). This ensures robust model selection and performance optimization across different geographical contexts and data characteristics. The framework outputs the best-performing model along with comprehensive performance metrics and uncertainty estimates.\n <br/>\n As a non-trivial application, we demonstrate the framework's effectiveness in predicting total organic carbon (TOC) concentrations[2] and sedimentation rates in the ocean. This involves integrating features from both the sea surface and seafloor, encompassing a diverse array of oceanographic, geological, geographic, biological, and biogeochemical parameters. The framework successfully identifies the most suitable model architecture and hyperparameters for this complex spatial prediction task, providing both high accuracy and reliable uncertainty quantification.\n</p>\n<p>\n <strong>\n References\n </strong>\n</p>\n<p>\n [1] Hollmann, N., Müller, S., Purucker, L.\n <i>\n et al.\n </i>\n Accurate predictions on small data with a tabular foundation model.\n <i>\n Nature\n </i>\n <strong>\n 637\n </strong>\n , 319–326 (2025).\n <a href=\"https://doi.org/10.1038/s41586-024-08328-6\" rel=\"noopener noreferrer\" target=\"_blank\">\n https://doi.org/10.1038/s41586-024-08328-6\n </a>\n</p>\n<p>\n [2] Parameswaran, N., Gonzalez, E., Burwicz-Galerne, E., Braack, M., & Wallmann, K.

Using a two-phase approach, the network is first pretrained on gap-free numerical model outputs masked with synthetic cloud patterns, then fine-tuned against sparse CMEMS observations with an additional independent validation mask. The framework architecture embeds a trainable dynamical prior and a convolutional LSTM solver to iteratively minimize a cost function that balances data agreement with physical consistency. The framework is applied for one year data (2020) of real observations (CMEMS) and co-located model simulations, demonstrating robust performance under operational conditions. Reconstructions capture major spatial patterns with correlation R2 = 0.977 and 50% of errors within ± 0.2 mg/L, even when 27% of days lack any observations. Sensitivity experiments reveal that removing 60% of available data doubles RMSE and smooths fine-scale SPM spatial features. Moreover, increasing the assimilation window reduces edge discontinuities between the data-void area and the adjacent data-rich region, whereas degrades sub-daily variability. Extending 4DVarNet to higher temporal resolution (hourly) reconstruction will require incorporating tidal dynamics to account for SPM resuspension, enabling real-time sediment transport forecasting in coastal environments.\n</p>\n", "presentation_type": "Talk", "session": "Artificial Intelligence/ Machine Learning methods in Earth System Sciences", "start": "2025-09-03T15:00:00+02:00", "duration": "00:15:00", "authors": [ { "author": { "first_name": "Wei", "last_name": "Chen", "orcid": null }, "affiliation": [ "Helmholtz-Zentrum Hereon" ], "is_presenter": true }, { "author": { "first_name": "Nga", "last_name": "Nguyen", "orcid": null }, "affiliation": [ "IMT Atlantique Bretagne-Pays de la Loire Campus de Brest Technople" ], "is_presenter": false }, { "author": { "first_name": "Johannes", "last_name": "Pein", "orcid": null }, "affiliation": [ "Helmholtz-Zentrum Hereon" ], "is_presenter": false }, { "author": { "first_name": "Frédéric", "last_name": "Jourdin", "orcid": null }, "affiliation": [ "Service hydrographique et oceanographique de la marine (Shom)" ], "is_presenter": false }, { "author": { "first_name": "Joanna", "last_name": "Staneva", "orcid": null }, "affiliation": [ "Helmholtz-Zentrum Hereon" ], "is_presenter": false }, { "author": { "first_name": "Ronan", "last_name": "Fablet", "orcid": null }, "affiliation": [ "IMT Atlantique Bretagne-Pays de la Loire Campus de Brest Technople" ], "is_presenter": false } ], "submitter": "Wei Chen", "event": "Data Science Symposium 2025", "activity": "MareHub", "accepted": true, "license": "Creative Commons Attribution 4.0 International (CC-BY-4.0)", "affiliations": [ "Helmholtz-Zentrum Hereon", "IMT Atlantique Bretagne-Pays de la Loire Campus de Brest Technople", "Service hydrographique et oceanographique de la marine (Shom)" ] }, { "title": "iFDOs: A Key to Unlocking the Potential of Marine Image Datasets", "url": "/submissions/99", "abstract": "<p>\n Images and videos are usually a more vivid data source than raw scalar 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 . The standardized nature of iFDOs enables interoperability between curation and annotation tools, allowing researchers to choose the tools that fit their workflow. To achieve this, we are developing the\n <a href=\"https://o2a-data.de/tools/ifdo-creator/\" rel=\"noopener noreferrer\" target=\"_blank\">\n iFDO Creator\n </a>\n , which allows researchers to create and edit iFDOs with a focus on usability.

One of the Baltic’s most remarkable features is its surface salinity gradient that is horizontally decreasing from the saline North Sea to the near fresh Bothnian Sea in the north, and Gulf of Finland in the east. Additionally, a vertical gradient and strong stratification separate between less saline surface water and deep saline water. These salinity features are mainly driven by a combination of river runoff, net precipitation, wind conditions, and geographic features that lead to restricted and irregular inflow of saltwater into the Baltic and limited mixing. The overall positive freshwater balance causes the Baltic to be much fresher compared to fully marine ocean waters with a mean salinity of only about 7 g/kg. The Baltic Sea is particularly sensitive to climate change and global warming due to its shallowness, small volume and limited exchange with the world oceans. Consequently, it is changing more rapidly than other regions. Recent changes in salinity are less clear due to a high variability but overall surface salinity seems to decrease with a simultaneous increase in the deeper water layers. Furthermore. the overall salinity distribution is indirectly linked to the general circulation of the Baltic Sea which consists mainly of cyclonic circulation cells comprising the main sub-basins of the Baltic Sea.
