EXPOCODE, or the "expedition code", is a unique alphanumeric identifier defined by the National Oceanographic Data Center (NODC) of the US. The code defines a standard nomenclature for cruise labels of research vessels and intends to avoid confusion in oceanographic data management. The code was used by international projects (WOCE, CarboOcean) and is considered a de facto standard in the international hydrographic community beginning with the Climate Variability Program (CLIVAR) and the EU-Project Eurofleets. The format of an expocode for an oceanographic cruise is defined in the format NODCYYYYMMDD where: * ''NODC'' is NOAA's National Oceanographic Data Center's 4-character research vessel identifier, consisting of country and ship code * ''YYYYMMDD'' is the GMT date when the cruise left port. Example for a cruise of the US research vessel ''Nathaniel B. Palmer'', starting on 2011-02-19: 320620110219 (Code of US = 32, code of Palmer = 06, date when cruise starts 2011-02-19) ==External links== * (NODC country codes ) * (NODC ship codes ) * (CLIVAR and Carbon Hydrographic Data Office (CCHDO) ) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Expocode」の詳細全文を読む スポンサード リンク
