The November 2020 mooring was deployed on cruise DY116 after a six month delay due to COVID restrictions.

The 30m frame was not deployed and only surface instrumentation is available in NRT.

On 20th Feb 2021, the battery unit failed on the transmitter and no NRT data are currently being sent. Data should still be recorded onboard the instrumnets adn will be recovered when the mooring is serviced in March.

Below are the graphs generated in near-real time from data gathered at PAP and transmitted via iridium servers up until the faulire.

Note - the Met system uses a seperate transmission system that is still operating as normal

 

Other data, including that from the two microcat sensors, were collected at the site but were not transmitted in near-real time.

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.
