Definition
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. It materially affects habitat, slope stability, and climate records by controlling the properties and composition of seabed deposits. The concept is generally stable, though analytical resolution and property measurement methods improve over time.
Principle
Principle
Standardize provenance, spatial extent, temporal coverage, instrument and processing descriptions so that datasets are discoverable, interoperable, and reproducible according to FAIR principles.
Demonstration
Demonstration
A metadata record for a contourite drift survey lists survey ID, vessel and instrument IDs (multibeam, sub-bottom profiler), acquisition dates, spatial bounding polygon in a defined CRS, sediment core identifiers, data quality flags, processing scripts and versions, resolution and vertical datum for bathymetry, and contact for data stewardship.
Misapplication
Misapplication
Treating a brief dataset title or a single README note as a complete metadata record, omitting coordinate reference systems, processing parameters, or provenance, which prevents reproducible interpretation and integration.
Consequence
Consequence
Well-formed metadata enables cataloging, automated harvesting, correct georeferencing in GIS, reproducible reprocessing, and proper attribution in multi-survey syntheses.
Reversal
Reversal
Raw data files without accompanying standardized metadata: acquisition logs, unknown processing chains, and unspecified coordinate systems that impede reuse.
Boundary
Boundary
Covers descriptive and technical documentation about the data but does not substitute for the data files themselves, detailed lab reports for cores (beyond identifiers), or external institutional policies.
Semantic Tension
Semantic Tension
Metadata record versus data product: a metadata record documents and points to data but is not the geospatial raster or vector representation of drift attributes; confusion arises when metadata fields are mistaken for derived map layers.
Synthesis
Synthesis
A Contourite Drift Metadata Record is the standardized descriptive and provenance wrapper—structured for machines and humans—that documents where, how, and by whom contourite drift data were acquired and processed so the data can be found, interpreted, and reliably reused.
