Guide

Here you will find proposed guidelines for standardizing sample metadata to describe interdisciplinary samples within DOE's Environmental Systems Science community.

Most of the sample metadata follows SESAR's metadata guidelines. However, we modified some metadata elements, specific requirements, and vocabularies based on ESS community needs. This includes additional fields, which mostly come from biodiversity standards Darwin Core, or genomic standards Minimum Information about any Sequence (MIxS).

We seek any additional feedback, with the goal of making ESS sample information Findable, Accessible, Interoperable, and Reusable (FAIR).

Elevation start

Elevation end

Proposed ESS-DIVE Element|maximumElevationInMeters Optional| |:------------------------|:----------------------------------------------------| |Definition |Maximum elevation at which a sample was collected, if elevation was taken over a range. | |Format |Number | |Additional Instructions|Leave blank if elevation is a single value and not range. Provide elevation in meters where possible.| |Examples |689.2 |

Elevation unit

Proposed ESS-DIVE Element|elevationUnit (recommend meters) if relevant, Required| |:------------------------|:----------------------------------------------------| |Definition |Unit that elevation start and/or end are provided in. |Format |Recommend meters. | |Additional Instructions|This will be removed when elevation field is changed to specify meters. | |Examples |meters|

Minimum Depth in Meters

Note that SESAR field is "Depth in Core (min)" Proposed ESS-DIVE Element|minimumDepthInMeters if relevant, Required| |:------------------------|:----------------------------------------------------| |Definition |Depth, or minimum depth (if taken over a range) at which a sample was collected, below ground or under water. | |Format |Number | |Additional Instructions|Recommend using meters. | |Examples |0.001 |

Maximum Depth in Meters

Note that SESAR field is "Depth in Core (max)" Proposed ESS-DIVE Element|maximumDepthInMeters if relevant, Required| |:------------------------|:----------------------------------------------------| |Format |Number | |Definition |Maximum depth at which a sample was collected, below ground or under water. | |Additional Instructions|Recommend using meters. | |Examples |0.003|

Depth scale

Proposed ESS-DIVE Element|depthUnit (recommend meters) if relevant, Required| |:------------------------|:----------------------------------------------------| |Format |Recommend meters. | |Definition |Unit in which the depth is provided, should be meters.| |Additional Instructions|This field will be deleted when we change the depth field to be required in meters.| |Examples |meters|

Minimum Distance above Surface in Meters

Not a SESAR Field Proposed ESS-DIVE Element|minimumDistanceAboveSurfaceInMeters Optional| |:------------------------|:----------------------------------------------------| |Definition |Minimum height above the ground surface, in meters. If no range of values collected, provide height measurement here.| |Format |Number | |Additional Instructions| | |Examples |4.2 |

Maximum Distance above Surface in Meters

Not a SESAR Field Proposed ESS-DIVE Element|maximumDistanceAboveSurfaceInMeters Optional| |:------------------------|:----------------------------------------------------| |Definition |Maximum height above the ground surface, in meters.| |Format |Number | |Additional Instructions| | |Examples |7.2 |

Environmental Context

Physiographic feature

Proposed ESS-DIVE Element|localEnvironmentalContext Recommended| |:------------------------|:----------------------------------------------------| |Definition |Entity or entities which are in your sample or specimen’s local vicinity and which you believe have significant causal influences on your sample or specimen. | |Format |Terms from Environment Ontology (ENVO). Provide the appropriate term and ENVO identifier - see examples below.| |Additional Instructions|Choose environmental context that is a smaller spatial grain than your entry for biome. Delimit multiple values using semi-colon. If needed, request new terms on the ENVO tracker, identified here.| |Examples |river [ENVO:00000022]; pond [ENVO:00000033]; wet meadow ecosystem [ENVO:01000449]; mountain [ENVO:00000081] For annotating a pooled sample taken from various vegetation layers in a forest, consider: canopy [ENVO:00000047]; herb and fern layer [ENVO:01000337]; litter layer [ENVO:01000338]; understory [01000335]; shrub layer [ENVO:01000336].|

Biome

Not a SESAR Field Proposed ESS-DIVE Element|biome Recommended| |:------------------------|:----------------------------------------------------| |Definition |Major environmental system your sample or specimen came from. The systems identified should have a coarse spatial grain, to provide the general environmental context of where the sampling was done (e.g. were you in the desert or a rainforest?).| |Format |Terms from Environment Ontology (ENVO). Provide the appropriate term and ENVO identifier - see examples below.| |Additional Instructions|We recommend using subclasses of ENVO’s biome class. Use a semi-colon to delimit multiple biomes where needed. If needed, request new terms on the ENVO tracker, identified here.| |Examples |shrubland biome [ENVO:01000176]; tropical moist broadleaf forest biome [ENVO:01000228]; estuarine biome [ENVO:01000020]|

Sample Access

Release Date

Proposed ESS-DIVE Element|releaseDate Required| |:------------------------|:----------------------------------------------------| |Definition |Date when sample metadata should be publicly accessible and searchable. If null , defaults to date of registration in SESAR (recommended). | |Format |YYYY-MM-DD | |Additional Instructions|SESAR recommends that sample metadata become public within 2 years of sample registration.| |Examples |2018-03-15 |

Current Archive

Proposed ESS-DIVE Element|currentArchive Optional| |:------------------------|:----------------------------------------------------| |Definition |Name of institution, museum, or repository where the sample is currently stored.| |Format | | |Additional Instructions|Only applies to physical samples that are archived in a collection for some period of time.| |Examples |Geosciences and Environmental Change Science Center, USGS Federal Center, Lakewood, CO|
