Measurements at 1 point, 1 date :

Soil characteristics - Greece (eco2adapt)

https://entrepot.recherche.data.gouv.fr/dataset.xhtml?persistentId=doi:10.57745/QJNQVN

Evaluation: Poor, no spatial info, no procedural info

Contents:

  • Excel Data File
    • No spatial information
    • Depth info in Excel
    • Contains conversion factors for specific properties
    • UoM as additional row under ObsProps
    • No procedural information
  • Metadata file
    • Only administrative info, responsibles

Measurements at multiple points (x,y are there), 1 date :

Large variability of soil microbial diversity and functions in an over 20-year old Eucalyptus grandis plantation

https://dataverse.cirad.fr/dataset.xhtml?persistentId=doi:10.18167/DVN1/QN22CM

Evaluation: Poor, only relative spatial information, no real coordinates. UoM difficult as mixing in Property. Does include procedure

Contents:

  • Excel Data File
    • readme tab contains all columns with description, UoM and methodology
      • includes depth information for all locations
      • Site location is not provided in readme, only name of site "Itatinga Experimental Station, University of São Paulo"
      • spatial information provided in m, but no information on the origin
      • issues with UoM as usually includes compound, should be shifted to ObsProp.
        • Not UoM "mg C g-1 soil DW h-1", ObsProp "Glucose-induced respiration rate"
        • Should be UoM "mg g-1 h-1", ObsProp "Glucose-induced respiration rate as C in soil DW"
    • data file: fairly normal
      • one column includes %, other just provide a fraction, though UoM same
  • Metadata file
    • in addition to administrative metadata, quite a bit of descriptive content.
    • Includes keywords, partially even from AgroVoc.

Dataset of soil and cacao leaf samples collected in all regions of Côte d'Ivoire

https://dataverse.cirad.fr/dataset.xhtml?persistentId=doi:10.18167/DVN1/PWM9WW

Evaluation: Good!

Contents:

  • CIV_Cacao_sols Nguessan.txt - metadata
    • Contains ObsProp, UoM and method for all columns
  • CIV_Cacao_sols Nguessan.xlsx - data
    • coordinates seem to be WGS84 (or related)
    • some values are colored (red or green), unclear what this means

Soil characteristics - Finland (eco2adapt)

https://entrepot.recherche.data.gouv.fr/dataset.xhtml?persistentId=doi:10.57745/USNIMD

  • same as Greek monitoring (eco2adapt)

Evaluation: Poor, no spatial info, no procedural info

Contents:

  • dataset
    • many values include "<", e.g. "< 1"
  • metadata
    • administrative data full stop

Measurements at different times, at 1 point (no spatial info) :

Soil 4-m profile data

https://zenodo.org/records/14524990

Evaluation: Poor, no spatial info, no procedural info

Contents:

  • dataset
    • no spatial information, only sample ID
    • ObsProps explained for first table, other tables without explaination
  • No additional metadata provided

Measurements at multiple points and multiple times (will we have this situation in the Mission Soil projects ? I can investigate during MS week the 5-6 nevember) :

Long term monitoring of near surface soil temperature in the french Alps part of ORCHAMP observatory

https://entrepot.recherche.data.gouv.fr/dataset.xhtml?persistentId=doi:10.57745/TVAHUQ

Evaluation: Excellent!!! Only issue is that some bits are nested in further files, some in french

Contents:

  • data
    • additional metadata file in data, includes valuable information, e.g. CRS
      • links to further metadata files, includes
        • measurement design
        • information on the sensor model
        • accuracy
        • UoM is hidden, but there
    • file with spatial information of all locations (CRS described above)

    • Data file clean, ID, Timestamp, Value

  • metadata
    • mostly administrative, but does include keywords, more than others

Long term monitoring of near surface soil temperature in the french Alps

https://entrepot.recherche.data.gouv.fr/dataset.xhtml?persistentId=doi:10.57745/JOZ1NA

Evaluation: Could be excellent if the data were actually provided

Contents:

  • Dataset
    • Same additional information as "Long term monitoring of near surface soil temperature in the french Alps part of ORCHAMP observatory" above
    • Missing the actual datasets
  • Metadata
    • Same as "Long term monitoring of near surface soil temperature in the french Alps part of ORCHAMP observatory" above

Measurements with no spatial and temporal information (located in the article probably):

Replication Data for: "Phosphorus sorption capacity and availability along a toposequence of agricultural soils: distinct effects of soil type and decadal fertilizer applications"

https://dataverse.cirad.fr/dataset.xhtml?persistentId=doi:10.18167/DVN1/CUII08

Evaluation: OK, much relevant information encoded in prose

Contents:

  • Dataset
    • readme with additional info on ObsProps (name, procedure, UoM) as prose
  • Metadata
    • basic administrative
    • keywords from agrovoc
    • procedural information in prose

Structure:

  • column for location (not given)
  • additional columns per ObsProp
  • time in filename

Replication Data for: "Increased soil pH and dissolved organic matter after a decade of organic fertilizer application mitigates copper and zinc availability despite contamination"

https://dataverse.cirad.fr/dataset.xhtml?persistentId=doi:10.18167/DVN1/C7WTZB&version=2.0

Evaluation: OK, same as "Replication Data for: "Phosphorus sorption..." above, only different is ObsProp groups

Contents:

Structure:

  • column for location (not given)
  • additional columns per ObsProp
    • additional header row to indicate ObsProp groups
  • time in filename
  • some UoM as column (Rate unit)
