Methodology
• Cleaning of whole ANTOBIS database
• Depth data added to all benthic records using ETOPO2 data
• Species counts vs number of stations maps for each major phylum (nematoda, mollusca, cnidaria, echinodermata, chordata, arthropoda & annelida)
• Species counts vs number of stations maps for major groups: (fish, birds and mammals, pelagic & benthic)
• Depth analysis. Numbers of benthic stations & species by depth

Summary
• Spatial & taxonomic coverage varies greatly between groups
• Major taxa “missing”: Sponges, Isopods, Pycnogonids, Bryozoans, Decapoda, Crinoidea & Brachiopoda
• Under-sampled & un-sampled areas: W. Weddell Sea, Amundsen Sea, deep sea

Fish

Summary• Bias towards shallow, presence of bases and ship routes
• Overall dataset: bird & mammal observations and tags dominate the station analysis
• Benthic data drives overall pattern of species richness
• Concurrence between benthic data hotspots and station presence
• Fish and CPR observation data drive pelagic data patterns

Depth Analysis

Conclusions• Sampling bias's drive many of the patterns• Depth bias, massive under sampling in deep water for
benthos• Well sampled areas and groups are suitable for
further analysis and predictions………..

Plea for help……..
• New “bi-polar” species coordinator!• New sponge dataset!• More datasets needed for modelling and
phylogenetic analysis
