PAP April 2017
The Apr 2017 mooring was deployed on cruise DY077.
Below are the graphs currently being generated in near-real time from data being gathered at PAP and transmitted via iridium servers.
Other data are being collected at the site but are not being transmitted in near-real time. Click on an image to see a larger version.

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.
