4. Key questions Where do we know least? Geographic, bathymetric, taxonomic and other biases…How good are our existing data and understanding?Sample design, scaling issues, interpretation of data… What drives patterns in biodiversity?Pattern assessment, fit of physical data, modelling

5. Epibenthic sledge (EBS) A high resolution tool to investigate macrofaunal patterns • complementary sampling; > 160 deployments • multiple spatial scales (1-1000 kms) • across major regions (Amundsen, Bellingshausen, Weddell, Scotia & Ross seas) • spanning > 6000 m depth • ANDEEP I-III, BIOPEARL I-II, BASWAP, EASIZ II-III, IPY-CAML

6. EBS synthesis manuscript • Spatial variability in macrofaunal abundance & diversity • Appropriateness of biodiversity measures (cf. qualitative data) • Do the supra-/epinet sample different faunas? • Mining value from `heterogeneous` data sets • Environmental data: sediment, productivity, organic content

7. EBS synthesis manuscript Data set: • Family level data: Isopods, poriferans, gastropods, bivalves, ostracods, bryozoans, polychaetes • Generic level: isopods, gastropods, polychaetes, bryozoans • ANDEEP I-III, ANDEEP-SYSTCO, BIOPEARL 1 & 2, EASIZ II, Oceans 20/20 • Weddell Sea, Scotia Sea, Amundsen Sea, Chatham Rise & Challenger Plateau (S. Pacific) • Proposed deadline: 30. November 2010

8. EBS meta data • Problems • EBS sorting time consuming & still in progress • ID: different levels of taxonomic resolution • Data share agreement • 1st step • taxonomist participation and data location • geographic scope • sample status • existing literature (based on the data set)

9. Progress in SO benthic biodiversity 1.) Phylogeography/Deep Phylogeny - Florian Leese2.) Classical biogeography - Katrin Linse3.) Sampling effort - Stefano Schiaparelli4.) New techniques in taxonomy - Saskia Brix5.) Data from imaging/New habitats - David Bowden6.) Antarctic biodiversity estimates - David Barnes7.) Ecophysiological vulnerability - Jeroen Ingels Intro/ discussion and coordination – Stefanie Kaiser, Saskia Brix, Simone N. Brandão Deadline 1. October 2010

10. Conclusions • ‘Discussive‘ style of workshop • Macrofaunal biodiversity synthesis ms underway • Review of last decade of biodiversity progress started • New grant initiative to improve biodiversity resolution • Progress on direction of future SCAR programmes
