Welcome to the EMSO ERIC Data Portal
Set atop an active volcano, the Lucky Strike, and its hydrothermal field, EMSO-Azores observatory gives unique research opportunities. The hydrothermal vent, which is a fissure in Earth's surface from which hot water comes out, can be investigated with a multidisciplinary approach. The hosted peculiar fauna and microbial communities, the water composition and circulation are studied. Being at the Mid-Atlantic Ridge, where tectonic plates diverge, the site allows studying closely tectonic and volcanic activities.
The Black Sea is one of the largest regional seas of the Eurasian continent and unique in many of its geographical, geological, biological, hydrographical and socio-political characteristics. With anoxic conditions in the deep, problems with invasive species and high sediment loads delivered to the system, this area has unique problems requiring long-term stations. The Black Sea is located in a geologically complex area, where three major tectonic plates (Eurasian, Anatolian, Arabian) interact. Geohazards, such as earthquakes, submarine landslides, displacement along active faults, are present and are possible triggers of tsunamis, together with extreme meteorological events.
A branch of the North Atlantic Current flows southwestward and then around the Canary Islands. This current, which is named Canary current, is characterized by cold temperature. Here, a phenomenon called upwelling occurs: deep waters, which are cold and rich in nutrients, move towards the surface and replace the surface waters, which are warm and poor in nutrients. Upwelling has consequences of marine ecosystems, affecting fisheries.
The Hellenic Arc is a subduction zone, that is where one tectonic plate “sink” under another one. It is the most tectonically active region in Europe, with a variety of geohazards, such as high seismicity, slope instabilities, and tsunami. The deep ecosystem is weak in nutrients (oligotrophic) and sensitive to climate change. The region is also on the routes of many cetaceans, that can be monitored through bioacoustic sensors, which are part of the EMSO Regional Facility equipment.
The area of Cadiz is very important for geo-hazards. It was the site where one of the worst earthquake that hit Europe occured in 1755, coupled with a destructive tsunami. Here African and European tectonic plates converge. It is a seismic a volcanic region. It is also the site to investigate the flow that from Mediterranean move into the Atlantic and affects the deep-water circulation on global scale. The geologic and oceanographic features of this region favour the presence of highly diverse benthic communities and have also a central role in the distribution of several marine mammals and fish species.
The Ligurian Sea is an active seismic region surrounded by a narrow and steep continental slope and alpine reliefs. Ligurian seismic events are not rare for seismic hazard evaluation in the Nice area and a similar event could be occurred along the margin at the level of the French-Italian border. Such event will produce destruction in a zone which is presently much more densely populated and could also be associated with a tsunami along the coast. The region is also characterized by the presence of rivers becoming streams after heavy rainfall. This promotes slope instability and the formation of submarine canyons. The Ligurian Sea is also strongly influenced by atmospheric inputs triggering changes in biomass production.
The Molène archipelago is part of the Natural Marine Parc d’Iroise, a marine protected area hosting a rich biodiversity and biomass with the largest seaweed field in Europe, a wide range of benthic organism, endangered bird species and marine mammals, including bottlenose dolphins and seals. EMSO-Molène is a pilot for a new generation of multidisciplinary cabled and coastal observatories, based on reliable proven off the shelf technologies. The technologies were used in the design of the cable observatory EMSO-Ligure Nice.
OBSEA - Expandable Seafloor Observatory - is an underwater laboratory that offers the possibility
to deploy different types of sensors, communication modules, or scientific experiments. It allows
real-time communication with the shore. It is placed at 20 m depth in the Balearic Sea (Mediterranean),
at 2.16 miles of Vilanova (Spain). It is used as a shallow-water test site.
OBSEA is connected with 4 km of cable to the coast of Vilanova i la Geltru (Barcelona, Spain) and placed at a depth of 20 meters in a fishing protected area. Besides, a buoy located at 40m from OBSEA works as a surface platform for measuring oceanographic and environmental parameters. The communication between the ground station and the buoy is done via a wireless 3G connection.
The Porcupine Abyssal Plain is vast plain situated at a water depth between 4000 and 4850 m. This site has being been studied for over 30 years. It is positioned between the North Atlantic current and the Azores Currents and it is crossed by clockwise and anticlockwise swirls and eddies. Its seabed hosts a rich living community, that is sampled and photographed. The combined monitoring data sets capture short-term (daily-seasonal), longer-term trends (climate driven) and episodic events (e.g. spring bloom) and the data contribute to the Europe-wide move toward good environmental status of our seas.
The SmartBay test site is within the confines of Galway Bay, 1.5km offshore, in water depths of about 21 meters. The facility includes surface buoys and a subsea seabed observatory with fibre optic data and power allowing novel marine sensors and equipment to be tested in a real marine environment with real-time monitoring of performance.
The area is prone to numerous natural hazards due to high seismicity and the presence of Mount Etna, one of the biggest and active volcanoes in Europe. The region experiences earthquakes and tsunamis due to the collision between African and European plates. Western Ionian is also a key site for the oceanographic circulation between the Eastern and Western Mediterranean Sea through the Messina Strait and the Sicily Channel. Besides, Western Ionian is a test site for the construction of an underwater neutrino telescope (KM3NET).
