The EXPOCODE consists of

  1. the two digit NODC country code; e.g. for Germany = 06 or USA = 32
  2. an NODC defined abbreviation of the vessel consisting of letters and/or numbers; e.g. for Meteor (1986) = MT or Nathaniel B. Palmer = 06
  3. the date of the first day of the cruise in the format JJJJMMDD
  • Example for a cruise of the US research vessel Nathaniel B. Palmer, starting on 2011-02-19: 320620110219

Attension! There is a slight difference for research vessels from Germany using the ships own cruise label in a modified form instead of the start date - examples:

  • cruise M15/3 of the Germany research vessel Meteor: 06MT15_3
  • cruise ANT-XV/4 of Polarstern: 06AQANTXV_4

If the cruise is part of an international project and the EXPOCODE is used, it should be added to the Campaign table by using the Optional label field.

In the EU-project Eurofleets a new convention for cruise naming was developed:

  • Naming cruises (Survey/Cruise Id): (SDN ship Code)+(yyyyMMdd start survey date).
    • Example: 29HE20101223 is the name of a survey onboard BIO Hesperides research vessel starting 23 of December 2010.
  • Naming CSR: Same as cruise Id with “_csr.xml” extension.
  • Naming CDI: (Cruise Id) _(leg, sample or station name)_(instrument name)+xml Example: 29HE20101223_station1_ctd.xml (CTD of station1 from Hesperides starting 23-12-2010 cruise).

Der Expocode ist ein eindeutiger cruise identifier, bestehend aus einem Laender code, einem Schiffscode und dem Datum der ersten Messung. Beispiel fuer Polarstern:

  • 06 (Deutschland)
  • AQ (Polarstern)
  • 19940817 (yyyymmdd)
  • original cruise label(?) (ANTX_5 = event label problem!, correct wäre ANT-X/5)

Eintrag im Feld 'optional label'; zukünftig ev eigenes Feld in 4D und in den Metadaten des Events. Beispiel: Campaign: ... Expocode: ... Basis: ... etc.

In der Ozeanographie wird der Expocode insbesondere in neueren Datensammlungen häufiger verwendent.
