SESAR Vocabularies
This page contains the controlled or recommended vocabularies used for select SESAR² metadata fields. Controlled lists are marked with an asterisk (*).
See the SESAR Quick Guide for the complete list of SESAR metadata fields and their definitions.
If you have questions about metadata content, please contact the SESAR Curator at info@geosamples.org.
Registration Metadata
Sample Type (Object) *
SESAR registers specimens and related sampling features collected from the natural environment.
- Core – long cylindrical cores
 - Core Catcher – material recovered from the core catcher of a sedimentary core and which is treated as a separate section from the core.
 - Core Half Round – half-cylindrical products of along-axis split of a whole round
 - Core Piece – material occurring between unambiguous [as curated] breaks in recovery.
 - Core Quarter Round – quarter-cylindrical products of along-axis split of a half round.
 - Core Section – arbitrarily cut segments of a “core”
 - Core Section Half – half-cylindrical products of along-axis split of a section or its component fragments through a selected diameter.
 - Core Slab – rectangular prism of material taken from a core where one dimension is significantly shorter than the others.
 - Core Sub-Piece – unambiguously mated portion of a larger piece noted for curatorial management of the material.
 - Core U-Channel – long rectangular prism of material for continuous measurement.
 - Core Whole Round – cylindrical segments of core or core section material.
 - CTD – a CTD (Conductivity, Temperature, and Depth) cast sample.
 - Cuttings – loose, coarse, unconsolidated material suspended in drilling fluid.
 - Dredge – a group of rocks collected by dragging a dredge along the seafloor.
 - Experimental Specimen– a synthetic material used during an experiment
 - Grab – a sample (sometimes mechanically collected) from a deposit or area, not intended to be representative of the deposit or area.
 - Hole – hole cavity and walls surrounding that cavity.
 - Individual Sample – a sample that is an individual unit, including rock hand samples, a biological specimen, or a bottle of fluid.
 - Oriented Core – core that can be positioned on the surface in the same way that it was arranged in the borehole before extraction.
 - Other – a sample that does not fit any of the existing type designations. It is expected that further detailed description of the particular sample will be provided.
 - Rock Powder – a sample created from pulverizing a rock to powder.
 - Site – a place where a sample is collected.
 - Terrestrial Section – a sample of a section of the near-surface Earth, generally in the critical zone.

Descriptive Metadata
Sub-Object Type*
If the object type for a sample is Individual Sample or Experimental Specimen, users may elect to enter a sub-object type.
Individual Sample
- Bead– Bead pressed from a powder.
 - Chemical Fraction- Parts of a parent sample separated chemically.
 - Cube- Equidimensional prism of material.
 - Culture- Biological material cultured in geological material.
 - Cylinder- Cylinders of material.
 - Gas- A gaseous material.
 - Liquid- A liquid material.
 - Mechanical Fraction- Parts of a parent sample separated mechanically.
 - Powder- Fine-grained (<62 micron), dry, granular material.
 - Slab- Rectangular prism of material where one dimension is significantly shorter than the others.
 - Smear- A toothpick sample suspended in liquid and fixed on slide.
 - Specimen- Material of any shape or form selected for specific characteristics of interest.
 - Squeeze Cake- Solid fraction remaining after forced expulsion of interstitial fluids from a source sample; typically has the shape of a cylindrical disc.
 - Thin Section- A sub-millimeter thick slice of material mounted on a glass slide.
 - Toothpick- Minute amount of material taken for observation.
 - Wedge- Sample form factor named for the tool used to extract it. Typically 5-20 ml in volume.
