PAP April 2016

Time series list

The April 2016 mooring was deployed on RRS Discovery cruise DY050

Below are the graphs generated in near-real time from data gathered at PAP and transmitted via iridium servers.  
Unfortunately, the transmission failed shortly after deployment, and near real time data feeds were lost.  
The sensors continued to operate and record data locally, and were recovered in April 2017 when the mooring was serviced.

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.

A diverse range of Essential Climate variables are measured and sampled at the PAP site from the atmosphere and surface ocean to the seafloor. Seafloor sampling includes trawling, coring, towed camera systems from a research ship and time-lapse photography. Since 2002 many of the upper ocean measurements (0-1000m) have been transmitted in near real-time.

Seafloor samples have been taken at the PAP site for over 20 years. Many methods can only be achieved from research ships but some (time-lapse camera) is autonomous for high resolution long-term sampling.
