Temperature and salinity profiles, metadata or trajectories from the Argo floats deployed by the UK or in the Southern Ocean may be obtained.

UK floats

UK float data may be accessed via an interactive map.

Southern Ocean floats

Southern Ocean float data may be accessed from the Argo Global Data Centres via a link provided in the interactive map.

Further information for UK floats

Interactive map

An interactive map created using ESRI software displays all UK Argo floats. You can opt to display various layers, such as, active, overdue or failed floats; their deployment location and their trajectories. There is also the option of superimposing a 2000 m bathymetric contour, sub-sampled from the General Bathymetric Chart of the Oceans (GEBCO) data set.

Tools allow you to zoom, pan, query and select floats of interest. Float identification, last profile date and position and a plot of the temperature and salinity profile are displayed below the map area.

UK floats interactive map layers

  • Active Apex — Webb Apex floats that last transmitted less than 10 days ago.
  • Active Provor — Martec Provor floats that last transmitted less than 10 days ago.
  • Overdue Apex — Webb Apex floats that last transmitted over 10 days ago but less than 90 days ago.
  • Overdue Provor — Martec Provor floats that last transmitted over 10 days ago but less than 90 days ago.
  • Failed Apex — Webb Apex floats that last transmitted over 90 days ago.
  • Failed Provor — Martec Provor floats that last transmitted over 90 days ago.
  • Deployment (Apex) — Webb Apex float deployments (regardless of status).
  • Deployment (Provor) — Martec Provor float deployments (regardless of status).
  • Surface Trajectories (Apex) — Webb Apex surface trajectories (last known 90 days).
  • Surface Trajectories (Provor) — Martec Provor surface trajectories (last known 90 days).
  • 2000 m bathymetry — 2000 m bathymetric contour (sub-sampled from GEBCO).
  • Land — Land outline

Further information for Southern Ocean floats

Interactive map

An interactive map created using ESRI software displays all Southern OceanArgo floats. You can opt to display various layers such as status, age, country of origin, deployment location or the float trajectories. There is also the option of superimposing a 2000m bathymetric contour, sub-sampled from the General Bathymetric Chart of the Oceans (GEBCO) data set and sea ice extent from the University of Bremen.

Tools allow you to zoom, pan, query and select floats of interest. Information about the selected floats and links to data (netCDF format) are displayed below the map area.

Southern Ocean floats interactive map layers

  • Last position (country) — Last position colour coded with country of origin.
  • Last position (age) — Last position colour coded with age.
  • Deployment — Float deployment positions (regardless of status).
  • Trajectories (3 months) — Surface trajectories in the last 3 months.
  • Trajectories — Surface trajectories.
  • 150 km buffer — 150 km buffer around last position.
  • Profile density (3 months) — Profile density in 3° by 3° area, in the last 3 months.
  • Profile density — Profile density in 3° by 3° area.
  • 3 x 3 grid — Grid with 3° increments.
  • 2000 m Bathymetry — 2000 m bathymetric contour line (Sub-sampled from GEBCO).
  • Sea ice extent — monthly average.
