marine sediment

A marine sediment concept defining how particles accumulate, are reworked, and change after burial on the seafloor. It governs depositional processes, physical properties, and post-depositional reactions measured through cores and laboratory analyses. It does not uniquely identify sources or processes without supporting stratigraphic, mineralogical, and geochemical evidence.

An Earth and environmental sciences concept defining a process, measurement, or principle used to understand Earth and its systems. It applies within stated assumptions and depends on reliable observation and analysis. It does not ensure correct inference without attention to scale, uncertainty, and validation.
