Sample Type (Object)*

* 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.
