The PAP telemetry mooring was deployed early on 7th October 2002 during RV Discovery cruise D266.

Unfortunately the top 150m of the mooring became detached on 10/12/2002. The telemetry kit continued transmitting data from some of the Microcat sensors and regularly giving positional data. The equipment was recovered by RV Triton an 1st March 2003.

The equipment functioned as a float buoy while it was adrift, and that data can be viewed here.

After recovery, data were archived at the British Oceanographic Data Centre (BODC) and can be accessed at: BODC PAP Collection, and temperature, salinity, conductivity and pressure data can be retrieved in user selected formats from the BODC ERDDAP service.
