Deep-sea coral and hydrothermal vent ecosystems, central Mid-Atlantic Ridge 2021-01-05T00:00:00Z publication mapDigital The spine of the Atlantic, the Mid-Atlantic Ridge is where new ocean crust is formed as plate tectonics pull the two sides of the Atlantic Ocean apart. In a narrow zone along the axis of the ridge the heat from volcanic activity drives hydrothermal venting at the seafloor, which supports a unique and diverse ecosystem that includes specialist chemosynthetic organisms and species that can tolerate the harsh conditions in and around the active hydrothermal vents. On the rocky flanks of the ridge and nearby seamounts, deep-sea corals attach themselves and feed on the organic-rich detritus brought in on the ocean currents. Mid-ocean ridge ecosystems are potentially at risk from the emerging deep-sea mining industry, which is set to target seafloor massive sulphide deposits that occur along the mid-ocean ridge.

However, GEOMAR noted possible mapping opportunities in Region#3 but outside the areas of national jurisdiction. Therefore, the area was expanded to capture these opportunities, namely to encompass the Greater Meteor Seamount complex (proposed as a new EBSA) and portions of the MAR south of the Azores EEZ. The new weird shape was not a problem to the group.After the September 2020 SC meeting, the area #3 was expanded further south to include the Broken Spur Hydrothermal Vent (Latitude: 29.1700 Longitude: -43.1717). https://www.geonode.iatlantic.eu WWW:LINK-1.0-http--link Online link to the '3.
