The document discusses the need for a shared earth model to manage big data from subsea and subsurface exploration. It notes requirements like managing large volumes of seismic, bathymetry and other data; being open, scalable, and cost-efficient; and enabling sharing and collaboration. A shared earth model is needed for exploration, development, production planning, environmental management, and delineating maritime boundaries. It proposes using ArcGIS and Geocap tools to integrate subsurface data and interpretations with GIS, allowing visualization and sharing of big data while avoiding data duplication.
