  • A study led by the National Oceanography Centre (NOC) has revealed a biogeographical boundary at the bottom of the Pacific Ocean.
  • High biodiversity is maintained in deeper areas of the abyssal north Pacific seabed by phylum-level species shifts across this region.

Deep-sea canyon faunal heterogeneity greater than expected

Research at the National Oceanography Centre (NOC) reveals that benthic fauna in deep-sea canyons are much more varied than previously thought.
