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 (indicated by *).

September 2010 cruise to PAP: The PAP mooring was serviced and redeployed by the RV Celtic Explorer (cruise CE10005). This was a highly successful cruise, even though it was curtailed by the arrival of bad weather.

On the 11th January 2011 the connection between the buoy and the data hub in the sensor frame failed, and as a result no more data will be received from the sensors in the frame apart from the two Seabird MicroCAT CTDs which use a different communication cable. Those sensors which record data internally should continue to do so, and this data will be retrieved when the mooring is serviced in July 2011

May 2010 cruise to PAP: Follow the cruise diary and live data feed. A new mooring and surface buoy (collaboration between Met Office UK and NOC) have been deployed along with a seafloor bathysnap lander as part of the MODOO project (see seafloor section below).

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. In 2010, as part of the MODOO demonstration mission a seafloor lander with physical and biogeochemical sensors will be deployed on the seafloor. For the first time some datasets will be transmitted in near real-time from the abyssal depths. New variables include: CTD + Backscatter; ADCP (2 way, re-programmable for water profiling as well as burst sampling); Seismometer (2 way, retrieval of selected time period - 1 Minute - in the past e.g. seismic event) and Bottom Pressure Sensor; Sediment trap (2 way, re-programmable for change sampling interval); Optode; Digital Camera; Stand-alone hydrophone.
