Amphipods and the AMO

May, 2020

PAP-SO scientist Tammy Horton has discovered that amphipods, the key scavengers of the deep-sea floor have changed in a way that matches changes in surface ocean climate and discovered a new species in the giant amphipod genus Eurythenes.

Published in the journal Progress in Oceanography, the study results suggest a significant shift in the composition of scavenging amphipod communities following a shift in surface ocean conditions known as the Atlantic Multi-decadal Oscillation (AMO)

The time-series study of scavenging amphipods at the PAP-SO began in 1985 and continues to the present day. The Discovery Collections at NOC now hold over 5000 specimens of PAP-SO giant amphipods. Very few deep-sea studies that can match this 34-year record of change in the abyss. Click here and Click here to read the articles.
