Download AEBR 292 Seamount recovery: analysis of 20 years of time-series seafloor image data from the Graveyard Knolls, Chatham Rise, New Zealand

Benthic invertebrate communities on the Graveyard Knolls have been monitored over a period of 20 years, with photographic surveys of six features with a mixture of fishing histories. Multivariate analyses indicate little change in overall community patterns on five of the six features. However, on ‘Morgue’ which was heavily fished until its closure in 2001, there are indications that community structure might be changing and that branching stony corals are either regrowing or recolonising.
