The PAP moorings were redeployed on 12 July 2003.

The telemetry which should communicate with the satellite to relay data was found to be inoperative and so was not deployed.

An extra cruise was arranged (Poseidon 306) in November at which time new satellite communication equipment was deployed and delayed mode data was recovered.

After recovery, data were archived at the British Oceanographic Data Centre (BODC) and can be accessed at: BODC PAP Collection (please use the search term Porcupine or #5192 to find our data) and temperature, salinity, conductivity and pressure data can be retrieved in user selected formats from the BODC ERDDAP service.
