Processed imagery data collected off the western margin's deep-sea environment on Algoa Voyage 246, February 2018

The aim of the Integrated Ecosystem Program (IEP) Benthic Project is to establish a baseline for epi-benthic invertebrate distribution, in order to identify benthic indicators for long-term monitoring within the pre-determined IEP monitoring lines. Ten stations were successfully surveyed, on board the R/V Algoa in February 2018, using a towed under-water benthic camera. The acquired abundance data represents five stations from the Kleinsee transect, four from Namaqua and one from St Helena Bay.
