General description

Ocean Data View is a "spreadsheet" format, i.e. a set of rows each with the same fixed number of columns.

• ODV comprises three different column types:
  • Metadata columns (for instance, the operation number) which are always at the start of the row
  • Reference parameter columns (for instance depth, time, etc.) positioned after the metadata columns
  • Parameter columns positioned at the row end.

Each parameter column is associated with a quality indicator column.

• An ODV file includes three types of rows:
  • comment rows
  • column header rows
  • data rows.

• Each file comprises a single data type from among the follow three types:
  • vertical profiles measured in the ocean water column from the surface to the seabed
  • time series measured at a fixed point
  • measurements taken along the platform's trajectory (for instance, a ship's route or a buoy's drift).
