* Controlled list

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.
