Controlled Vocabularies

The OAE Data Protocol uses controlled vocabularies to standardize categorical values across metadata submissions. Some are defined as part of the protocol, while others reference established community standards.

For detailed definitions of each vocabulary, see the Controlled Vocabularies section of the OAE Data Protocol website.

Community Standard Vocabularies

The following vocabularies are sourced from established oceanographic & scientific community standards:

Vocabulary Source Used For
Sea Names NERC SDN:C16 Project geographic classification
Platform Type NERC SDN:L06 Dataset platform classification
Instrument Type NERC SDN:L05, SDN:L22, SDN:B75 Sampling and analyzing instruments
Units QUDT Dosing concentration units
