  2. Outline Introduction Western South Pacific Caribbean and Western Mid Atlantic Northeast Atlantic Mediterranean Region Concluding comments

  3. Facts: • 64% planet high seas • Oceans >95% biosphere • 14,000-100,000 seamounts • 64% (>130m) beyond national jurisdiction • Pressures: • Intensifying human uses • Climate change • Ocean acidification Credit: Halpern et al. 2008 (Science 319)

  4. Life started in the oceans 90% of planet’s living biomass in oceans >50% animal phyla yet to make it to land New species being found daily Even new ecosystems ¾ of oceanic sharks & rays threatened or near threatened Deepwater coral 3850m Tasmania

  5. Western South Pacific • GOODS Biogeographic boundaries modified by SPREP member territories • > 100m depth • Marine Biodiversity Value • 10,000 islands covering 40 million sq km of ocean • Epicentre of marine biodiversity • Fisheries and tourism • Climate change • Ocean acidification

  6. Data • 57 data layers (including modelled interpretation) • Physical oceanography (CSIRO) • Seafloor geology + (GA) • Deep sea coral (CoML and MCI) • Fisheries (SPC) • Species diversity (OBIS) • Birds (Birdlife International) • Turtles, whales??

  7. Collaboration • 13 Pacific nations • 9 international organisations • SPREP supported by CSIRO • Process • Initial identification • Explain data and criteria • Examine datasets on wall • Propose and justify • Enter into GIS database • Discuss and agree in plenary • Refine

  8. 26 Potential EBSAs 2 for future consideration

  9. Summary • ____ • ____ ____ • ____ ____ __ _____ _ ____________ • _________ ____ __ ____ _ _______ • ________ • ___________ _____ ____ • ______ ______ • ____ _____________

  10. Good collaborations – nations and scientists • Valuable data collation • Expert driven process – second workshop recommended for comprehensive result • EBSAs provide potential focus for research and monitoring • Connectivity and network issues remain to be resolved before COP IX/20 Annex II is considered.
