2 Census of Marine Life & OBIS A 10-year international project to assess the diversity, distribution and abundance of marine life.Ocean Biogeographic Information System (OBIS) is a data center for the Census.Ausubel, 1999; Grassle, 2000; Vanden Berghe et al, 2010.CoML:OBIS:
3 Global Biodiversity of Ocean Life OBIS Mission:Document diversity, distribution and abundance of marine lifeProvide biodiversity data to global biodiversity researchesRelated oral presentation “The Ocean Biogeographic Information System: current state and future plans” by E. Vanden Berghe (Abstract No. 0328)Biodiversity researches using OBIS data e.g. Ardron et al, 2009 ; Tittensor et al, 2010.

13 Environmental Attributes (3) Extract observations based on environmental conditionsExample map #1Cetacean species observations in LME region ‘Celtic-Biscay Shelf’(no environmental conditions set)Example map #2Cetacean species observations in LME region ‘Celtic-Biscay Shelf’ filtered by a temperature range of 13 to 15 degrees
14 Data in Region of Interest (1) Extract observations in a region of interest (study area)Draw a region on the mapFixed size (CSquare cell)RectanglePolygonDefine a region by coordinatesCan edit / fine-tune the regionDrawing tools allow you to draw a rectangular region (above) or a polygon of any shape (right) on the map. Can edit it with numeric coordinates.
15 Data in Region of Interest (2) Extract observations in commonly referred zonesZone selectionFrom listClick a zone on mapObs. locations are pre- referenced to zonesFast extraction onlineExample mapCetacean species observations in LME region ‘Celtic-Biscay Shelf’* Future plan

17 Cloud Computing (1) Cloud computing from Amazon EC2 Provides most flexibility in the allocation of base level resourcesChoice of OS and software versionsScaling of disk, processor, and RAMThrow-away development instances for learning and testingFreedom from:Server ownership and hardware maintenanceCampus network authentication and admin rulesEncouraged very systematic server configurationInstances could be built quicklyInstance setup can be scripted
18 Clone of tested new data disk previous data revision Cloud Computing (2)Novel approach to data managementTest new data on virtual disk of dev serverNew data disk image is attached to production serverDevelopmentdatabase serverProductionDatabase serverNew data loaded through system administration, rather than database administrationMinimal downtime as disk is mounted and database is restartedClone of tested new data diskNew dataVirtual diskOld disk discardedprevious data revision
19 Cloud Computing (3)Scaling for major media event, London Press ConferenceSporadic scaling-up possibleIn cases for expected high demands such as media eventsiOBIS application & on-the-fly data search isn’t cacheableChallenge of the media event coped wellTwo Quad Core, 15GB RAM servers: Database & PortalPeak day: 3,157 visitors averaging 3:28 minutes on the Data Search application11,000 total site visitorsMajor surge of accesses to the iOBIS Portal witnessed during the London Press Conference in October 2010

21 OBIS Data in Products (2) CBD Ecologically or Biologically Significant AreasPresented in CBD COP10, Nagoya, Japan, 2010Areas of high biodiversityAreas of special importance for the life history of a speciesAreas of significant naturalnessAreas of uniqueness or rarityRelated presentation “Using Ocean Biogeographic Information System data in the CBD EBSA process” by E. Vanden Berghe et al. is available (Abstract No. 1123).
22 Future Plans More advanced mapping & visualization Improved web servicesSupport regional/thematic map instantiationImprove database performanceFacilitate collaboration among the International OBIS NetworkMirror sitesRegional nodesImproved biological data representationDiGIR schema upgradesNon-traditional data types (e.g. acoustic data, telemetry-tracked animals)Tackle emerging demands of OBIS dataMarine spatial planning

25 AcknowledgmentsWe would like to thank Alfred P. Sloan Foundation for unprecedented efforts to make the Census project possible. We also would like to thank all contributors organizing OBIS regional and thematic nodes. Finally, we express deepest appreciation to data providers around the world; without them, the OBIS database would not be made possible.
