Northern Australian Marine Invertebrate Catalogue, Australia (2009-2012)

OBIS Australia Open in mapper Explore occurrences

Between 2009-2012, Geoscience Australia conducted three surveys to Joseph Bonaparte Gulf and the Timor Sea on the R.V. Solander, in collaboration with the Australian Institute of Science and the Museum and Art Gallery of the Northern Territory. The study areas overlapped the Oceanic Shoals Commonwealth Marine Reserve and the carbonate banks and terraces within it. The surveys were conducted as part of the Australian Government's Energy Security Program (2007-2011) and the National Environment Research Program (2011-2015). On the surveys, a benthic sled was deployed to collect biological samples from the seafloor. Samples were sorted onboard according to phylum, photographed and then sent to taxonomists for species-level identifications. This catalogue includes all onboard photographs taken from identified samples. Sponges were the only group of which all samples were identified, but they include high proportions of unnamed or undescribed species. The catalogue also includes taxonomic identification sheets so that users can cross-reference the species names and images with location and depth.
