Bottom pressure recorders

The map below indicates sites where bottom pressure recorder data are available.

Most of these bottom pressure records have been collected as part of the Antarctic Circumpolar Current Levels by Altimetry and Island Measurements (ACCLAIM) programme, conducted by the Proudman Oceanographic Laboratory (POL). Find out more about ACCLAIM from the POL ACCLAIM web pages.

Data files and site history information may be accessed via the following inventories

Click on the Access the data to download the data and View the documentation to view the site history information. The data are available in BODC request format (ASCII) and WOCE netCDF format. Sites are ordered by latitude and longitude.
