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

• Indian Ocean
• Drake Passage, Scotia Sea and Weddell Sea
• South and Central Atlantic

In addition to the bottom pressure data collected by POL, other bottom pressure data have been collected by the USA. These are described in the table below.

The instruments used were Sea-Bird SBE-16 SEACATs. The data files contain the following parameters

• Temperature (°C)
• Pressure (db)
• Conductivity (mmho cm^-1)
• Salinity (psu)

These data are available from the Oregon State University (OSU) Buoy Group web site.
