PAP November 2020
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, are being collected at the site but are not transmitted in near-real time.
After recovery, data are archived at the British Oceanographic Data Centre (BODC) and can be accessed at: BODC PAP Collection

Seafloor (4850 m)
Seafloor samples have been taken at the PAP site since 1985. The following techniques are used to observe change over time:
| Method | Used for | Contact at NOCS, UK |
|---|---|---|
| Trawl | Megafaunal species abundance, diversity and biomass | Dr Brian Bett, Dr Jen Durden |
| Sea Floor Photography | AUV and towed camera photography for spatial studies. High resolution time-lapse photography (8 hours) in fixed location | Dr Brian Bett, Dr Jen Durden |
| Sediment Cores | Megacorer (a type of multiple corer) for infauna and geochemistry | Dr Brian Bett, Dr Jen Durden |
| Baited Traps | Time series observation of scavenging assemblage. Data available from OBIS | Dr Tammy Horton |
