Element concentrations in seawater are governed by solubility and residence time rather than by crustal abundance: an element abundant in rock may be vanishingly rare in the ocean if it does not stay in solution.
- method: Follows from the cited distinction between dissolved and particulate transport; Lithoen holds no seawater concentration data.
- precision note: Recorded as a principle rather than with values, because no seawater concentration datum was verified in Phase 2.
Evidence support: Supported by the cited evidence 2 sources, multiple sources, independence unknown
Evidence: Gosen 2017 Primary authority; British Geological Survey n.d. Primary authority
