The MODOO Demonstration Mission aims to demonstrate the functioning of a MOdular and mobile Deep Ocean Observatory (MODOO) with real-time data access. The MODOO concept is linking and operating existing stand-alone observatories such that they merge into a single observatory. MODOO is mobile (or re-locatable) as it can be moved to regions where it is required, MODOO is modular as its architecture allows other stand-alone systems to connect to MODOO.
For this Demo-Mission MODOO will be operated at the Porcupine Abyssal Plain (PAP), 350 nm off southwest Ireland, one of the ESONET NoE's key sites. At the PAP site exists the longest running multidisciplinary open ocean time-series in Europe. The science is dedicated to improve our understanding of the complex oceanic processes from surface waters to the seafloor. Short-term variability of the oceans is examined, including physical mixing, ecosystem dynamics and nutrient cycling. Also longer-term trends in the Earth’s climate are investigated. MODOO will make use of the existing water column mooring infrastructure at PAP, which forms part of the EuroSITES network of European Eulerian ocean observatories and develop this within the objectives of ESONET beyond the current state-of-the-art. MODOO will demonstrate one of the deepest acoustic links from the deep seafloor to the surface integrating the existing water column observatory with a benthic lander observatory into a single, realtime accessible observatory. MODOO is a second phase ESONET demonstration mission.

The MODOO kickoff meeting was held at NOCS on the 7-8 May 2009.
