PAP April 2016
The PAP1 observatory hosts a suite of meteorological, physical and biogeochemical sensors. The most current data are available below from the deployment in July 2015. The research ship RRS Discovery cruise DY050 serviced the mooring in April 2016.
We will add the delayed mode data as soon as it is quality checked.
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 (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. 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 (two-way, re-programmable for water profiling as well as burst sampling); Seismometer (two-way, retrieval of selected time period – 1 minute – in the past, e.g., seismic event) and Bottom Pressure Sensor; Sediment trap (two-way, re-programmable for change sampling interval); Optode; Digital Camera; Stand-alone hydrophone.
