Abstract

Paleoclimate research increasingly relies on the synthesis of heterogeneous proxy records to investigate climate variability across spatial and temporal scales. However, the reuse and integration of paleoclimate data remain limited by inconsistent formats, fragmented analytical workflows, divergent nomenclature and practices, and implicit methodological assumptions. Improved open data access, while helpful, is insufficient to ensure reproducibility and enable large-scale scientific discovery on its own. Here, we present an integrated framework for advancing open and reproducible paleoclimatology through three complementary developments. First, we build on community standards to harmonize the representation of paleoclimate data and metadata, connecting structured data formats with controlled vocabularies via an ontology. Second, we implement these semantic relationships within a knowledge graph …
