Download AEBR 221 – Quantifying benthic diversity: developing a dataset of benthic invertebrate faunal distributions from seabed photographic surveys of Chatham Rise.

This report is a summary of work to develop a coherent dataset of benthic invertebrate distributions on Chatham Rise based on seabed photographic surveys. The dataset spans the full extent of Chatham Rise in depths from 40 m to 1850 m, combining analyses of 358 seabed transects from five surveys. The primary purpose of the dataset is to enable development of improved predictive models of faunal distributions that can be used to inform ecosystem-based management of the region.
