| id |
Internal database ID. In event.txt identical to eventsID and constituting a unique identifier for the event (= sampling event). In measurementorfact.txt it is the ID of the event at which the measurement was taken. |
| eventID |
Unique ID for the record, identical to id. |
| parentEventID |
An identifier for the broader event that groups this and potentially other events – in this case, a link to the database internal ID of the station and included in the file only for compliance with the schema. |
| samplingProtocol |
A free-text description of the method/ protocol used during the sampling event. |
| sampleSizeValue |
A numeric value for a measurement of the size (time duration, length, area, or volume) of a sample in a sampling event. Does not contain values here, included only for compliance with the schema. |
| sampleSizeUnit |
The unit of measurement of the size (time duration, length, area, or volume) of a sample in a sampling event. Does not contain values here, included only for compliance with the schema. |
| samplingEffort |
Sampling time in minutes |
| eventDate |
The date and time of sampling, recorded in standard format (ISO 8601:2004). |
| year |
The year of sampling (four digits). |
| month |
The month of sampling (one or two digits). |
| day |
The day of the month of sampling (one or two digits). |
| habitat |
A description of the habitat of the sample, in this case representing the information contained in the column "Nature of Bottom" of the original publication. |
| fieldNumber |
A unique sampling code (across the digitized datasets). Here composed of the locationID and year and an incrementing small letter to distinguish between different sampling events at the same station in the same year. |
| eventRemarks |
The name of research vessel, the bottom or sampling depth given and other remarks on the original text. Includes also any information from the original publications which was corrected during the digitization in cases it was clearly incorrect. |
| locationID |
The station code as reported on the original text plus the sampling year, in some cases with slight modifications in order to avoid the same station code being used for different locations. |
| locality |
The name of the locality of the sampling station, if given in the publication. |
| minimumDepthInMeters |
The minimum (shallowest) sampling depth of the event. |
| maximumDepthInMeters |
The maximum (deepest) sampling depth of the event. |
| locationRemarks |
Comments or notes about the location and its coordinates. |
| decimalLatitude |
The geographic latitude (in decimal degrees, using the spatial reference system given in geodeticDatum) of the geographic center of a Location. Positive values are north of the Equator, negative values are south of it. |
| decimalLongitude |
The geographic longitude (in decimal degrees, using the spatial reference system given in geodeticDatum) of the geographic center of a Location. Positive values are east of the Greenwich Meridian, negative values are west of it. |
| coordinateUncertaintyInMeters |
A radius of uncertainty around the given coordinates (in metres). The true location / coordinates may fall anywhere within that circle. |
| measurementID |
A unique identifier for the MeasurementOrFact (information pertaining to measurements, facts, characteristics, or assertions). |
| measurementType |
The type of the measurement (e.g. Chlorine at the water surface) |
| measurementValue |
The value of the measurement. |
| measurementAccuracy |
he description of the potential error associated with the measurementValue |
| measurementUnit |
The unit associated with the measurementValue. |
| measurementDeterminedBy |
Person(s) who determined the measurementValue. |
| measurementMethod |
A description of or reference to (publication, URI) the method or protocol used to determine the measurement |
| measurementRemarks |
Comments or notes about the measurement. |
