The material spans the Phanerozoic, with reconstructions spanning 000-545 Ma (v0) and 330-550 Ma (v1), and includes: GeoTIFF maps in ESRI:54034 projection (10x10 km resolution) for global, area-preserving analysis. Sea-level summaries with calculated ocean volumes, areas, and eustatic adjustments based on Airy’s eustasy.
