Keynotes

Modern research in the area of earth observation (EO) and computational ecology poses challenges on the computing, storage, and communication infrastructure needed to analyze the huge volumes of data obtained from remote sensing systems. To develop, run, optimize, and maintain EO processing workflows, geoscientists nowadays need to have both in-depth domain knowledge as well as extensive skills in data science and IT systems. Workflow developers face the challenges of inconsistent terminology, a vast number of algorithms, contradictory recommendations, non-transparent data (pre-)processing, and the lack of comprehensive standards for workflow specification and data exchange. This results in very limited code and artifact reusability as well as poor result reproducibility. Moreover, the integration and scalable processing of huge data volumes (up to Petabytes) from multiple distributed and heterogeneous sources poses a significant entry barrier for geoscientists.

In this context, we introduce a new large-scale research initiative aiming to address the above challenges through a collaboration between computer scientists, geoscientists, and ecologists in an interdisciplinary setting. The Research Unit "SOS: Serverless Scientific Computing and Engineering for Earth Observation and Sustainability Research (DFG FOR)" (https://dfg-sos.de) includes partners from the University of Würzburg, the German Aerospace Center (DLR), the Leibniz Supercomputing Sentre (LRZ), and the Max Planck Institute of Animal Behavior (MPIAB). Established in January 2025 by the German Research Foundation (DFG), this long-term project pursues three main goals: (1) significantly lower the technical entry barrier for the development and execution of complex high-volume EO workflows with multiple distributed and heterogeneous data sources in an interdisciplinary setting, (2) enable application-level automation, sharing, and (third-party) reuse of EO workflows—including workflow designs, implementations, and research data—across projects, teams, application domains, and organizations, and (3) address a set of exemplary interdisciplinary research questions focussed on investigating the impact of climate change on the land surface dynamics (snow cover, snowmelt) and the movement pathways of migratory animals, as a basis for predicting future space use and species composition. We discuss the current state of the project and present some initial results towards providing semantically enriched and reusable EO workflow components.

Alaska represents the United States in the Arctic region and comes with a natural hazard unique to the Arctic: Permafrost thaw. Permafrost is ground that has remained frozen for at least two consecutive years and it can be ice-rich, resulting in sinkholes when the ground-ice melts. Nearly 170,000 people (or 192 communities) live on permafrost with over 80% of Alaska’s communities disconnected to the road system. These remote and permafrost-affected communities hold critical infrastructure for national security (runways etc). Simultaneously, many remote communities do not have a local governing body (county or borough) that otherwise would provide resources. Further, Alaska has the lowest grade in geospatial data maturity of all States in the United States where basic infrastructure data is not even digitally available. The Permafrost Discovery Gateway, which is a free online platform, aims to enable big geospatial data creation, access, and usability (think sub-meter across the Arctic) for permafrost science and hazard management. We are living in exciting times where we finally have the technology to dig into big data, generate, and present helpful information to enable science and the management of land and infrastructure. You will hear about how we are bringing together a broad team and multiple approaches to empower people, no matter their technical and financial resources, in addressing permafrost thaw hazards for a thriving Alaska and Arctic region.
