Seamounts (>1000 m rise from sea floor)


This assessment summary component has changed in 2016. 

  • Consultation with experts questioned the specification of a depth categorisation specifically "this is a geological definition – the ecological definition of ‘seamount’ includes hills and pinnacles that may only rise 200-500 m from the surrounding seafloor, but have clearly different habitats and different impacts from the surrounding seafloor". To support the requirement of providing a comprehensive assessment of seamounts the depth categorisation was removed
