Registration Metadata
Sample Type (Object) *
SESAR² 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.
