Compass: Navigating Global Marine Lead Data Integration through Expert-Guided LLM Agent

arXiv:2605.29966v1 Announce Type: new Abstract: Marine lead (Pb) and its isotopes are critical tracers for ocean circulation and anthropogenic pollution, yet in-situ observations remain costly and sparse. While vast historical records exist, they lie buried within the unstructured content of academic papers, creating "data silos" inaccessible to comprehensive analysis. Manual extraction is unscalable, while general-purpose Large Language Models (LLMs) lack the necessary domain-specific knowledge, leading to hallucinations and scientifically invalid outputs. To address this, we introduce an exp

Why this matters
Why now

The proliferation of LLMs creates both opportunities and challenges for extracting structured data from vast, unstructured scientific repositories, making expert-guided solutions essential. The increasing recognition of 'data silos' in critical scientific domains like marine science drives the need for advanced data integration tools.

Why it’s important

This development addresses a critical bottleneck in scientific research by enabling the scalable extraction of essential environmental data, which was previously inaccessible for comprehensive analysis. It highlights the growing specialization of AI applications to overcome limitations of general-purpose models in specific, complex domains.

What changes

The ability to efficiently extract and integrate previously inaccessible scientific data from academic papers transforms our capacity for large-scale environmental analysis and modeling. It shifts the paradigm from manual, unscalable data collection to automated, AI-driven extraction guided by domain expertise.

Second-order effects
Direct

Domain-specific AI agents become critical tools for unlocking structured data from scientific literature across various fields.

Second

Improved data availability leads to more robust environmental models and better-informed policy decisions regarding pollution and ocean health.

Third

The success of expert-guided LLM agents encourages their development in other fields facing 'data silo' challenges, accelerating scientific discovery and data synthesis across disciplines.
