A range of univariate metrics describing benthic faunal biodiversity across Chatham Rise and Challenger Plateau. Data were collected in 2007.
This report presents diversity metrics of benthic organisms between and within the Chatham Rise and the Challenger Plateau areas sampled during Ocean Survey 20/20 voyages to the area in March-April and May-June 2007. The Ocean Survey 20/20 voyages represent the most comprehensive sampling initiative in these areas to date and aimed to describe patterns of benthic habitat and biological diversity across extensive areas of the EEZ. Objective 6 (addressed in this report) was devised to provide information about the biodiversity of the Chatham Rise and Challenger Plateau; compare many of the different indices of biodiversity available; and analyse how these vary across a range of spatial scales and taxonomic resolutions.
