COSYNA Underwater Observatories at AWI

Since 2012, the Alfred-Wegener-Institute operates two shallow-water cabled underwater observatories (UWO’s) in the Southern North Sea North off Helgoland (Helgoland-UWO - 59° 11'N / 8° 52,79E – Fig. 1) and in the Arctic Ocean in Spitzbergen (Svalbard-UWO - 78° 55.200 / 11° 54.00 – (WGS84) - Fig. 2). The systems were developed in close cooperation with the Helmholtz Centre Geesthacht (HZG) within the framework of COSYNA.

Both systems are operated year round with the objectives to:

  • Provide near real-time data (NRT-Data) of the main hydrographical variables of the two AWI research sites “Southern North Sea” and “Kongsfjord”.
  • Provide underwater power and data connection for short-term or long-term project based sensor exposure for AWI research groups and cooperating research partners.
  • Providing an underwater test facility for new sensors and sensor developments for AWI research groups, cooperating research partners and cooperating companies.
