Distribution and diversity of mesopelagic fauna on seamounts of the Madeira-Tore complex (Northeastern Atlantic)
Mesopelagic organisms play an important role in the vertical carbon flux through diel vertical migrations. The mesopelagic fauna of three NE Atlantic seamounts (Gorringe Bank, Josephine and Seine) and surrounding oceanic waters were sampled. Echogram scrutiny suggests a diel vertical migration of th...

Mesopelagic organisms play an important role in the vertical carbon flux through diel vertical migrations.
