object type

We have modified the original SESAR IGSN list of object type terms for Environmental Systems Science (ESS) samples. Currently, you must use SESAR terms to register samples for IGSNs. Please provide feedback on any additional terms needed, modifications to definitions needed, or terms that should be removed.

ESS-DIVE Object Type	SESAR IGSN Label	Description
Core	Core	A long cylindrical sample, usually of soil or sediment (for Environmental System Science).
Core Section	Core Section	Segments of a "core", which can be arbitrarily cut or cut to obtain specific depths.
Cuttings	Cuttings	Loose, coarse, unconsolidated material suspended in drilling fluid.
Dredge	Dredge	A group of rocks collected by dragging a dredge along the seafloor.
Experimental Specimen	Experimental Specimen	A synthetic or natural material used during an experiment.
Grab	Grab	A sample (sometimes mechanically collected) from a deposit or area, not intended to be representative of the deposit or area.
Material Sample	Individual Sample	A sample that is an individual unit of material, including soil or sediment samples, biological material, or a bottle of fluid. A physical result of a sampling (or subsampling) event.
Filtrate	NA	A sample that has gone through a filtration process to separate solids from fluids (liquids or gases), using a filter medium through which only the fluid can pass. Must be associated with a filter size.
Material Captured in Filter	NA	A material sample captured in filter, for example from a water sample that was filtered. Must be associated with filter size field. Material options include: "particulate matter" or "particulate matter: organic particulate matter" .
Organism	NA	A whole specimen of a biological organism. A particular organism or defined group of organisms considered to be taxonomically homogeneous.
Part of organism	NA	A specimen of a portion of a biological organism (e.g. leaf, root, stem).
Collection of organisms	NA	A material entity that consists of two or more organisms, viruses, or viroids.
Site	Site	A place where a sample is collected.
