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 life Provide biodiversity data to global biodiversity researches Related 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.

4 International Partnership
International collaboration in international project for international audiences INCOIS India Infrastructure Mirror site iOBIS project PI Development lead Database development Duke Univ. USA Rutgers Univ. USA Univ. Simón Bolívar Vebezuela Search Interface development Hardware and Server infrastructure Host of OBIS-SEAMAP Web site programming and content Taxonomic expertise (Halpin et al, 2009) VLIZ Belgium Infrastructure Tool development GeoServer upgrade & support IOC & IODE

5 Renovated iOBIS Portal
Bring in latest technologies to better serve biodiversity data Example map: Cetacean species observations in LME region ‘Celtic-Biscay Shelf’ (left); (right)

6 Infrastructural View Concept & Philosophy Internet Amazon Cloud
Web site Search Interface Amazon Cloud Concept & Philosophy An intuitive system to browse the biodiversity data standards-compliant open-source interoperable and flexible for international development code replication Database replication Database management Portal development

7 Application Architecture
Front Page Search Interface Mapping Engine Database Drupal 6 OpenLayers 2.9 EXTJS 3.1 Javascript PHP 5.3 GeoServer 2.1 PostGIS 1.5 PostgreSQL 8.4 Apache 2 Tomcat 6 Ubuntu Ubuntu Extra Large Instance on Amazon Cloud Extra Large Instance on Amazon Cloud

8 Schema for Search Interface
Data Structure Schema for Search Interface Raw data (DiGIR table) Normalized tables Calculated point data Taxon info Positions Resources Additional attributes Denormalized for better performance Oceanographic data using WOA Keys to external layers such as EEZ Taxonomy Based on multiple taxon database WoRMS ITIS IRMNG COL Scripted Summarized tables Calculated summary data Per species Per species and resource Grids using CSquare 5/1/0.5/0.1 degree(s) Denormalized for better performance 5/1/0.5/0.1 degree(s) Supplemental EEZ etc. World Ocean Atlas CSquare Search Interface GeoServer

9 Standards-compliant Mapping Engine
Upgraded GeoServer provides OGC services Supports OGC standards WMS / WFS / KML Used for the online map and data downloads Parametric views introduced OpenGeo upgraded GeoServer for this project Implemented as vendor-specific parameters for OGC requests allow to extract data based on user inputs Example parametric view definition: %param_name% is a placeholder which is replaced with an actual value of the user inputs OGC: Open Geospatial Consortium (http://www.opengeospatial.org/)

10 Biodiversity indices Making various biodiversity indices handy
#species ES 50 Shannon Index Simpson Index

11 Environmental Attributes (1)
Association of observation points with oceanography Observation data associated with Bottom depth Temperature Salinity Nitrogen / Oxygen Phosphate / Silicate Visualized through interactive graphs Time-series graphs Histograms Environmental attributes from World Ocean Atlas WOA09,

12 Environmental Attributes (2)
Explore oceanographic attributes with interactive graphs Time-series graphs Average over time Zoom in/out on time scales Centuries / Decades Years / Year-months / Days Seasons or months of the year Histograms Zoom in/out on bin sizes Bin sizes optimized for oceanographic variables Average temp. over years One zoom level up Average temp. over year-month Histograms (left) and seasonal changes (right) also available

13 Environmental Attributes (3)
Extract observations based on environmental conditions Example map #1 Cetacean species observations in LME region ‘Celtic-Biscay Shelf’ (no environmental conditions set) Example map #2 Cetacean 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 map Fixed size (CSquare cell) Rectangle Polygon Define a region by coordinates Can edit / fine-tune the region Drawing 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 zones Zone selection From list Click a zone on map Obs. locations are pre- referenced to zones Fast extraction online Example map Cetacean species observations in LME region ‘Celtic-Biscay Shelf’ * Future plan

16 Multi-language Support

Русский (Russian) by Volodymyr Vladymyrov Nat’l Academy of Sciences of Ukraine Français (French) by Bruno Danis, GBIF contractor; Mary Kennedy, Roberta Miller and Mathieu Ouellet, Fisheries and Oceans Canada

17 Cloud Computing (1) Cloud computing from Amazon EC2
Provides most flexibility in the allocation of base level resources Choice of OS and software versions Scaling of disk, processor, and RAM Throw-away development instances for learning and testing Freedom from: Server ownership and hardware maintenance Campus network authentication and admin rules Encouraged very systematic server configuration Instances could be built quickly Instance setup can be scripted

18 Clone of tested new data disk previous data revision
Cloud Computing (2) Novel approach to data management Test new data on virtual disk of dev server New data disk image is attached to production server Development database server Production Database server New data loaded through system administration, rather than database administration Minimal downtime as disk is mounted and database is restarted Clone of tested new data disk New data Virtual disk Old disk discarded previous data revision

19 Cloud Computing (3) Scaling for major media event, London Press Conference Sporadic scaling-up possible In cases for expected high demands such as media events iOBIS application & on-the-fly data search isn’t cacheable Challenge of the media event coped well Two Quad Core, 15GB RAM servers: Database & Portal Peak day: 3,157 visitors averaging 3:28 minutes on the Data Search application 11,000 total site visitors Major surge of accesses to the iOBIS Portal witnessed during the London Press Conference in October 2010

20 OBIS Data in Products (1)
National Geographic Wall Map

21 OBIS Data in Products (2)
CBD Ecologically or Biologically Significant Areas Presented in CBD COP10, Nagoya, Japan, 2010 Areas of high biodiversity Areas of special importance for the life history of a species Areas of significant naturalness Areas of uniqueness or rarity Related 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 services Support regional/thematic map instantiation Improve database performance Facilitate collaboration among the International OBIS Network Mirror sites Regional nodes Improved biological data representation DiGIR schema upgrades Non-traditional data types (e.g. acoustic data, telemetry-tracked animals) Tackle emerging demands of OBIS data Marine spatial planning

25 Acknowledgments We 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.
