PAP July 2019

The July 2019 mooring was deployed on cruise DY103.

Near-real time data were transmitted via iridium servers until September 2019, when severe weather appears to have damaged the transmission system.

The near-real time data are shown in the graphs below.

It is hoped that on-board recording is still active.

After recovery, data will be archived at the British Oceanographic Data Centre (BODC) and can be accessed at: BODC PAP Collection

Data Extraction

Below are links to extract subsets of the real-time data collected during this deployment. Please note these are raw data as received from the sensors. They are NOT processed or calibrated and as such are not identical to the displayed graphs above. Each of these cruises are described in a cruise report which can be accessed from the cruises tab.


Seafloor (4800 m)

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.
