    description: Altitude is a term used to identify heights of objects such as airplanes,
      space shuttles, rockets, atmospheric balloons and heights of places such as
      atmospheric layers and clouds. It is used to measure the height of an object
      which is above the earth's surface. In this context, the altitude measurement
      is the vertical distance between the earth's surface above sea level and the
      sampled position in the air

  ecosystem:

    description: An ecosystem is a combination of a physical environment (abiotic
      factors) and all the organisms (biotic factors) that interact with this environment.
      Ecosystem is in position 1/5 in a GOLD path.
    comments:
    - The abiotic factors play a profound role on the type and composition of organisms
      in a given environment. The GOLD Ecosystem at the top of the five-level classification
      system is aimed at capturing the broader environment from which an organism
      or environmental sample is collected. The three broad groups under Ecosystem
      are Environmental, Host-associated, and Engineered. They represent samples collected
      from a natural environment or from another organism or from engineered environments
      like bioreactors respectively.

    comments:
    - The Environmental ecosystem (for example) is divided into Air, Aquatic and Terrestrial.
      Ecosystem categories for Host-associated samples can be individual hosts or
      phyla and for engineered samples it may be manipulated environments like bioreactors,
      solid waste etc.

    comments:
    - The Aquatic ecosystem category (for example) may have ecosystem types like Marine
      or Thermal springs etc. Ecosystem category Air may have Indoor air or Outdoor
      air as different Ecosystem Types. In the case of Host-associated samples, ecosystem
      type can represent Respiratory system, Digestive system, Roots etc.

    title: elevation, meters
    comments:
    - All elevations must be reported in meters. Provide the numerical portion only.
    - Please use https://www.advancedconverter.com/map-tools/find-altitude-by-coordinates,

    comments:
    - The abiotic factors play a profound role on the type and composition of organisms
      in a given environment. The GOLD Ecosystem at the top of the five-level classification
      system is aimed at capturing the broader environment from which an organism
      or environmental sample is collected. The three broad groups under Ecosystem
      are Environmental, Host-associated, and Engineered. They represent samples collected
      from a natural environment or from another organism or from engineered environments
      like bioreactors respectively.

      air as different Ecosystem Types. In the case of Host-associated samples, ecosystem
      type can represent Respiratory system, Digestive system, Roots etc.

    description: The total concentration of all dissolved salts in a liquid or solid
      sample. While salinity can be measured by a complete chemical analysis, this
      method is difficult and time consuming. More often, it is instead derived from
      the conductivity measurement. This is known as practical salinity. These derivations
      compare the specific conductance of the sample to a salinity standard such as
      seawater.

    description: An ecosystem is a combination of a physical environment (abiotic

      Ecosystem is in position 1/5 in a GOLD path.
    comments:
    - The abiotic factors play a profound role on the type and composition of organisms
      in a given environment. The GOLD Ecosystem at the top of the five-level classification
      system is aimed at capturing the broader environment from which an organism
      or environmental sample is collected. The three broad groups under Ecosystem
      are Environmental, Host-associated, and Engineered. They represent samples collected
      from a natural environment or from another organism or from engineered environments
      like bioreactors respectively.

      on specific characteristics of the environment from where an organism or sample
      is isolated. Ecosystem category is in position 2/5 in a GOLD path.
    comments:
    - The Environmental ecosystem (for example) is divided into Air, Aquatic and Terrestrial.
      Ecosystem categories for Host-associated samples can be individual hosts or
      phyla and for engineered samples it may be manipulated environments like bioreactors,
      solid waste etc.

    comments:
    - The Aquatic ecosystem category (for example) may have ecosystem types like Marine
      or Thermal springs etc. Ecosystem category Air may have Indoor air or Outdoor
      air as different Ecosystem Types. In the case of Host-associated samples, ecosystem
      type can represent Respiratory system, Digestive system, Roots etc.

    description: Elevation of the sampling site is its height above a fixed reference
      point, most commonly the mean sea level. Elevation is mainly used when referring
      to points on the earth's surface, while altitude is used for points above the
      surface, such as an aircraft in flight or a spacecraft in orbit.
    title: elevation, meters
    comments:
    - All elevations must be reported in meters. Provide the numerical portion only.
    - Please use https://www.advancedconverter.com/map-tools/find-altitude-by-coordinates,
      if needed, to help estimate the elevation based on latitude and longitude coordinates.

    - Currently, the comments say to use UUIDs. However, if we implement assigning
      NMDC identifiers with the minter we dont need to require a GUID. It can be an
      optional field to fill out only if they already have a resolvable ID.

    notes:

    comments:
    - Identifiers must be prefixed. Possible FAIR prefixes are IGSNs (http://www.geosamples.org/getigsn),
      NCBI biosample accession numbers, ARK identifiers (https://arks.org/). These
      IDs enable linking to derived analytes and subsamples. If you have not assigned
      FAIR identifiers to your samples, you can generate UUIDs (https://www.uuidgenerator.net/).
