Porcupine Abyssal Plain (PAP)

Latitude and Longitude: 49N,16.5W

Depth: 4800m

Oceanographic Region: Northeast Atlantic

History of the Site:

Since 1989, this environmental study site in the Northeast Atlantic has become a major focus for international and interdisciplinary scientific research and monitoring including water column biogeochemistry, physics and benthic biology. Since 2002, a mooring has been in place with sensors taking a diverse set of biogeochemical and physical measurements of the upper 1000m of the water column. Some of these data are transmitted in near real-time via satellite.

Enhancement/Modifications planned within EuroSITES:

Continuation: Real-time and delayed-mode data on PCO2, Chlorophyll, nutrients, water column physics and downward particle flux. Benthic biology including Bathysnap time-series camera system.
Enhancement: mesozooplankton analyser and oxygen consumption measurement
