Argo

The Argo programme of profiling oceanographic floats provides data freely and without restriction from the global full-depth interdisciplinary Argo observing network. Argo is coordinated by a steering team and data management team and supported by Jcommops:

• Argo Portal
• Argo Project Office, including Argo Steering Team information
• Argo Data Management Team, including a description of the data system and extensive documentation
• OceanOPS Argo Dashboard

The array consists of floats serving one or more of three primary missions:

• Core Argo – pressure, temperature and salinity to 2000 m
• Deep Argo – pressure, temperature and salinity to 6000 m
• Biogeochemical Argo – core measurements plus the following BGC measurements to 2000 m:
  • oxygen
  • pH
  • nitrate
  • irradiance
  • particle backscatter
  • chlorophyll-a fluorescence

Argo data is primarily available to users from the ftp servers at two Global Argo Data Centres (GDACs), which also have HTTPS access:

• Ifremer
• US GODAE

Data is also available via:

• Registry of Open Data on AWS
• RSYNC synchronisation service
• ERDDAP server
• THREDDS server
• and as monthly snapshots from the Argo DOI page

The data transmitted from Argo floats is managed by a network of Argo Data Assembly Centres (DACs):

• AOML
• BODC
• Coriolis
• CSIO
• CSIRO
• INCOIS
• JMA
• KMA
• KORDI
• MEDS
• NMDIS

A set of Argo Regional Centres (ARCs) work to ensure basin-scale data quality:

• Atlantic ARC
• Indian ARC
• Pacific ARC
• Southern Ocean ARC
• Mediterranean and Black Sea ARC

The Euro Argo European Research Infrastructure Consortium provides the following tools:

• Fleet Monitoring Dashboard
• Data Selection Tool
