About MioOcean

MioOcean is an open, community‑driven paleoceanographic database designed to compile, harmonize, and share proxy data to reconstruct ocean temperatures across the Miocene. Our aim is to create a unified resource that supports reproducible research, cross‑proxy comparisons, and large‑scale syntheses of past climate and ocean states.

The project re-evaluates and re-calculates existing age models and brings together geochemical proxy data from planktic and benthic foraminifera, as well as lipid biomarkers.

Our Mission

MioOcean exists to:

• Integrate dispersed paleoceanographic datasets into a single, consistent structure
• Enable comparison across sites, proxies, and time intervals
• Support open science and FAIR (Findable, Accessible, Interoperable, Reusable) data practices
• Accelerate scientific discovery by making high‑quality, curated data publicly accessible
• Encourage collaboration within the paleoceanographic community

Scientific Scope

MioOcean focuses on time intervals critical to understanding Earth’s past climate dynamics, including but not limited to:

• Miocene Climate Optimum (MCO)
• Middle Miocene Climate Transition (MMCT)
• Late Miocene Cooling (LMC)

As the database grows, new proxy data and proxy types will continue to be added through community contributions.
