Descriptor name | Description of usage | Control vocabulary/format/unit | Example | |
---|---|---|---|---|
SAMPLE_Title | A short informative description of the sample. Must be unique for each sample, (i.e. for each filter generated during sampling). | Format: <OSD_SiteID > _ < Month > _ < Year > _ < SiteName > _ < Protocol_Label > _ < SampleNo > _ < Depth> | OSD3_06_14_Helgoland_NPL022_1_surface | |
SAMPLE_Depth | The distance below the surface of the water at which a measurement was made or a sample was collected. | Format: ##.#; | 1.5 | |
Positive below the sea surface. | ||||
SDN:P06:46:ULAA for m | ||||
SAMPLE_Protocol_Label | Identifies the protocol used to produce the sample, e.g. filtration and preservation. | Term list; | NPL022 | |
See the SAMPLE_Protocol_Label in the OSD Protocols Section for details | ||||
SAMPLE_Quantity | Refers to the quantity of environment that was sampled, most often with dimensions Length, Amount, Mass or Time. | Format : ###.### | 20 Litres | |
See the SAMPLE_Quantity in the OSD Protocols Section for details | ||||
SAMPLE_Container | Refers to the container in which the sample is stored prior to analysis. | Term list; | Sterivex cartridge | |
See the SAMPLE_Container in the OSD Protocols Section for details | ||||
SAMPLE_Content | Refers to the content of the sample container. While the sample might target a specific organism (e.g. bacteria), the sample content might be a filter or a volume of water. | Term list; | Particulate matter on a 0.22 μm pore size filter | |
See the SAMPLE_Content in the OSD Protocols Section for details | ||||
SAMPLE_Size-Fraction_Upper-Threshold | Refers to the mesh/pore size used to pre-filter/pre-sort the sample. Materials larger than the size threshold are excluded from the sample. | Term list; | no pre-filtration | |
See the SAMPLE_Size-Fraction_Upper-Threshold in the OSD Protocols Section for details; in μm | ||||
SAMPLE_Size-Fraction_Lower-Threshold | Refers to the mesh/pore size used to retain the sample. Materials smaller than the size threshold are exclude from the sample. | Term list; | 0.22 | |
See the SAMPLE_Size-Fraction_Lower-Threshold in the OSD Protocols Section for details; in μm | ||||
SAMPLE_Treatment_Chemicals | Refers to the chemicals (e.g. preservatives) added to the sample. | Terms list: ChEBI; | None | |
See the SAMPLE_Treatment_Chemicals in the OSD Protocols Section for details | ||||
SAMPLE_Treatment_Storage | Refers to the conditions in which the sample is stored, e.g. temperature, light conditions, time. | Term list; | −80 degrees Celsius | |
See the SAMPLE_Treatment_Storage in the OSD Protocols Section for details |
