P01 parameter names
• Logical structure (semantic model)
• 3 main elements :
– The property observed
•
e.g. “concentration”
– The entity observed
•
e.g. a chemical substance like “phosphate” or a physical phenomenon like “waves” or a biological entity like
“Skeletonema costatum”
– The matrix
•
e.g. water body and its various phases, sediments and its various components, atmosphere and its various
components, etc.

Need to login as a BODC user
Helps search existing terms and request new terms
Currently only works with codes relating to a chemical substance
Will work on all P01 codes by October this year (SeaDataCloud deliverable)
