ESONET - The Vision

Virtual Institute of Scientific Users of Deep Sea Observatories

Data access

Scientists in the NOON-consortium are using advanced scientific echo-sounders located on the sea bottom to study the behavior of animals in the deep sea. Currently, three sonar are located in Masfjorden near Solheim, and you can find all the real-time data by following the link:

direct access to real-time data for:
- "Live" echo-sounder, 38 kHz transducer placed on the bottom of 375 meters depth
- "Live" echo-sounder, 120 kHz at 270 meters depth
- "Live" echo-sounder, 200 kHz at 90 meters depth


The Poseidon system aims at monitoring, forecasting and providing information for the Greek Seas. It is offering access to the most recent data recorded by the buoy network in the Aegean Sea and Ionian Sea. The data are available either as time series graphs or as text based format for the latest transmission:


The Porcupine Abyssal Plain (PAP) site has been set by euroSITES to observe changes in rate and state variables within the entire water column and benthos for a wide range of biogeochemically significant features. The PAP systems are currently on shore being serviced, but there will hopefully be data streaming from PAP on or around 1 June and thereafter. There is also data for previous periods going back almost 10 years:

Other EuroSITES with real-time data are listed at the EuroSITES website.

The Deep-Sea long-term observatory HAUSGARTEN comprises 16 permanent stations covering a depth range of 1.000 to 5.500 m water depth. Repeated sampling and the deployment of moorings and different free-falling systems, which act as observation platforms, has taken place since the beginning of our studies in summer 1999. At regular intervals, a Remotely Oparted Vehicle (ROV) is used for targeted sampling, the positioning and servicing of autonomous measuring instruments and the performance of in situ experiments. A 3.000 m depth-rated Autonomous Underwater Vehicle (AUV) will further extend the sensing and sampling programmes. Data are available in the Pangaea database: 


The Hardangerfjord observation buoy for environmental data

 The Institute of Marine Research (IMR, Bergen) collects information about natural environmental variations as part of its investigations related to the sea ecology and environmental impacts of aquaculture. The buoy measure the following parameters:
1. Wind (direction and strength)
2. Current (direction and strength)
3. Air temperature
4. Water temperature
5. Salinity

data presented have not been quality assured:

Having performed daily oceanographic measurements in the deep Norwegian Sea since 1 October 1948, Ocean Weather Ship Station (OWS) Mike, at 66°N, 2°E, can present the longest existing homogeneous time series from the deep ocean. Station M is operating above the eastern margin of the Norwegian Sea deep basin where a branch of the Atlantic current is entering the area.

The location proved to be strategic both for studying the Atlantic inflow and the Norwegian Sea Deep Water. The OWS M is operated by The Norwegian Meteorological Institute (DNMI) and the hydrographic programme is carried out by Geophysical Institute, the University of Bergen. Data from 1948 to 2007 can be downloaded from the website:

Unfortunately the funding for the ship Polar Front was withdrawn in 2009 and Polar Front is no longer available as the Station Mike platform. Moorings to replace some of the Station Mike functionality have been designed and these moorings are planned to be trialled as soon as possible at the Station Mike site.
