Giant cold water

carbonate mounds


The TTR cruise in 1997 made the first comprehensive study of these spectacular deep-water phenomena in the northeastern Atlantic. Seismic and sidescan sonar surveys of several frequencies combined with extensive bottom sampling programme and direct observations by deep-towed video systems provided clues for understanding the distribution and morphology of the carbonate mounds. Acoustic seafloor mapping and underwater video surveys revealed the connection between the mounds, cold water corals and fast flowing bottom currents.
