locationID

Location ID

An identifier for the set of location information (data associated with dcterms:Location). May be a global unique identifier or an identifier specific to the data set.

decimalLatitude

Decimal Latitude

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. Legal values lie between -90 and 90, inclusive.

Decimal degrees

decimalLongitude

Decimal Longitude

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. Legal values lie between -180 and 180, inclusive.

Decimal degrees

eventDate

Event Date

The date-time or interval during which an Event occurred. For occurrences, this is the date-time when the event was recorded. Not suitable for a time in a geological context.

depth

depth

The amount of effort expended during an Event.

sampleSizeValue

Sample Size Value

A numeric value for a measurement of the size (time duration, length, area, or volume) of a sample in a sampling event.

kilometerSquared

sampleSizeUnit

Sample Size Unit

The unit of measurement of the size (time duration, length, area, or volume) of a sample in a sampling event.

taxonID

Taxon ID

An identifier for the set of taxon information (data associated with the Taxon class). May be a global unique identifier or an identifier specific to the data set.

scientificName

Scientific Name

The full scientific name, with authorship and date information if known. When forming part of an Identification, this should be the name in lowest level taxonomic rank that can be determined. This term should not contain identification qualifications, which should instead be supplied in the IdentificationQualifier term.

acceptedNameUsage

density

Density

The number of organisms,designated by taxonomic names (e.g. species, genus, family), per unit area or per unit volume.

numberPerKilometerSquared

biomass

Biomass

The amount of living organic matter per unit area or per unit volume. It can be expressed in terms of biovolume, weight or carbon content and can be measured at different organisational levels.

kilogram

biomassPerUnitArea

Zoobenth_tax_ww_biomass

Zoobenthos wet weight biomass per unit area parameters presented at the level of taxa that may be mapped to entities in a standard taxonomy registry such as WoRMS or ITIS. Includes animals considered as planktonic if they have been returned from sediment samples.
