Accelerating Earth Science Discovery via Multi-Agent LLM Systems

2025-03-07

AI Summary

Earth science data face accessibility bottlenecks due to heterogeneous formats, inconsistent metadata standards, and vast volumes of unprocessed datasets. To address these challenges, this work introduces the first large language model–based multi-agent system (LLM-MAS) specifically designed for geoscience, integrating a natural language interface, dynamic workflow orchestration, and deep integration with the PANGAEA repository. The system enables natural language–driven data discovery, intelligent data cleaning, and cross-repository scientific reasoning. By decomposing complex analytical tasks into specialized, role-based agents, it overcomes the limitations of monolithic LLMs and supports end-to-end geoscientific analysis. Evaluated via the PANGAEA GPT prototype, the system significantly reduces data retrieval and preprocessing time, delivers structured answers to complex scientific queries, and facilitates interdisciplinary collaboration—thereby accelerating the scientific discovery loop.

Abstract

This Perspective explores the transformative potential of Multi-Agent Systems (MAS) powered by Large Language Models (LLMs) in the geosciences. Users of geoscientific data repositories face challenges due to the complexity and diversity of data formats, inconsistent metadata practices, and a considerable number of unprocessed datasets. MAS possesses transformative potential for improving scientists' interaction with geoscientific data by enabling intelligent data processing, natural language interfaces, and collaborative problem-solving capabilities. We illustrate this approach with"PANGAEA GPT", a specialized MAS pipeline integrated with the diverse PANGAEA database for Earth and Environmental Science, demonstrating how MAS-driven workflows can effectively manage complex datasets and accelerate scientific discovery. We discuss how MAS can address current data challenges in geosciences, highlight advancements in other scientific fields, and propose future directions for integrating MAS into geoscientific data processing pipelines. In this Perspective, we show how MAS can fundamentally improve data accessibility, promote cross-disciplinary collaboration, and accelerate geoscientific discoveries.
