  • 1. “OBIS is worlds largest online system for absorbing, integrating, and accessing data about life in the ocean” The Ocean Biogeographic Information System Ward Appeltans IOC-UNESCO/IODEIODE-XXII Pre-conference Workshop, 8-9 March 2013, Ensenada, Mexico
  • 2. Census of Marine Life (2000-2010)
  • 3. Census of Marine Life (2000-2010)•  2,700 scientists•  80+ nations•  540 expeditions•  US$ 650 million•  2,600+ scientific publications•  6,000+ potential new species•  30 million distribution records and counting
  • 4. Ocean Biogeographic Information SystemOBIS is the world’s largest open access, onlinerepository of spatially referenced marine life data that: –  Nations can use to develop national and regional assessments, to discover trends, gaps and biodiversity hotspots and to meet their obligations to the Convention on Biological Diversity and other international commitments. –  Stimulates research about our oceans to generate new hypotheses concerning evolutionary processes, species distributions, and roles of organisms in marine systems on a global scale. –  Forms a baseline of marine life’s diversity, distribution, and abundance against which future change can be measured.
  • 5. OBIS at IOC-UNESCO In June 2009, the 25th Session of the IOC Assembly decided through Resolution XXV-4 to adopt OBIS as part of IODE, because: 1. Knowledge of the oceans biodiversity is of such importance to national and global environmental issues that the responsibility for its continuing success should be assumed by governments. 2. IOC Member States have repeatedly identified the need to acquire ocean biogeographic data for national ocean and coastal resource management. 3. Without accurate, repeatable and timely biological data it is impossible to address adequately the global ocean environmental issues of pollution, climate impact and mitigation, ocean acidification, ecosystem management, biodiversity loss, and habitat destruction (Resolution of the UN General Assembly A/RES/63/111) 4. OBIS provided the opportunity to adopt an existing global network for biogeographic data and to attract the associated research community that can and should be a continuous part of the Commission’s ocean mandate.
  • 6. 10th Conference of the Parties to theConvention on Biological DiversityIn Nagoya October 2010, the 10th Conference of the Parties to the Convention onBiological Diversity (Decision COP10/29 para 10 and 35;) requested Member Statesto further enhance globally networked scientific efforts, such as the OceanBiogeographic Information System (OBIS), to continue to update a comprehensiveand accessible global database of all forms of life in the sea, and further assess andmap the distribution and abundance of species in the sea, and;Called upon IOC to facilitate availability and inter-operability of the bestavailable marine and coastal biodiversity data sets and information across global,regional and national scales.As a result OBIS is playing a crucial role in providing scientific guidance, data andinformation for the identification of Ecologically or Biologically Significant marineAreas, through a series of regional workshops in 2011, 2012 and 2013 convened bythe CBD, as part of the UN Strategic Plan for Biodiversity 2011-2020, and inparticular to contribute to Aichi Biodiversity Target 11 to conserve and sustainablymanage at least 10 per cent of coastal and marine areas by 2020.
  • 7. CBD-COP10 listed OBIS as a key source of information for the identification of Ecologically or Biologically Significant Areas (EBSAs) part of CBD" Areas of high biodiversity Areas of special importance for the life history of a speciesAreas of significant naturalness Areas of uniqueness or rarity
  • 8. OBIS contributions to the CBD process:"(1) national reporting and (2) open oceans & deep seas " National EEZ data queries Open-ocean ABNJ data queriesOpen-access data made International collaborativeavailable to all countries data and research in areas and communities beyond national jurisdiction
  • 9. OBIS contributions to the CBD EBSA process " North Pacific regional EBSA workshop, Moscow, 25 Feb – 1 March 2013
  • 10. OBIS contributions to the CBD EBSA process "OBIS data are being used tosupport the identification ofsites meeting the EBSAcriteria at each regionalworkshop.OBIS data layers include:•  Species observations•  Biological Diversity indices•  IUCN Red List species Eastern Tropical & Temperate Pacific EBSA workshop, Galapagos Ecuador, August 2012

  • 45. Establishment of new OBIS nodes(for consideration at IODE-XXII)•  If the institute is an existing NODC: –  Send a letter of “expression of interest” to the OBIS project office, wishing to join the OBIS network of nodes.•  If the institute is not an existing NODC, but wishes to apply for an NODC status: –  Follow the procedure for NODCs and include your wish to join the OBIS network of nodes.•  If the institute is an existing SODC (if the SODC entity type is adopted by the 22nd session of the IODE Committee): –  Send a letter of “expression of interest” to the OBIS project office, wishing to join the OBIS network.•  If the institute is not an existing SODC, but wishes to apply for an SODC status: –  Follow the procedure for SODCs and include your wish to join the OBIS network of nodes.
  • 46. Establishment of new OBIS nodes(for consideration at IODE-XXII)The extra information required for OBIS to include in the application/expression of interest is the following: –  Indicate the level of commitment to function as an OBIS tier II and/ or tier III node; –  Indicate the person who will act as the OBIS node manager (and deputy).Applications will be reviewed by the IODE Steering Group for OBIS and adecision will be made within two weeks after confirmation of receipt. Theresults of the decision from the 22nd session of the IODE Committee willaffect the final process developed by the SG-OBIS.
  • 47. OBIS Standards and Best Practices •  Metadata, no single standard –  ISO19115 compliancy (GCMD, FGCD, IMIS, EML..) •  Data –  Geography: OBIS extension of Darwin Core –  Taxonomy: basis = World Register of Marine Species, but also ITIS, CoL and IRMNG (when not in WoRMS). •  Data harvesting protocols –  GBIFs Integrated Publishing Toolkit (IPT) (txt file + EML) –  DiGIR (XML) –  CSV •  Data publishing services –  Maps using Open layers –  OGC/Open GIS web map/feature/coverage services (OBIS GeoServer)
  • 48. QC/data validation/quality flags•  Principle OBIS never change records –  data cleaning needs to be done at the expert/data providers level.•  OBIS can perform data integrity checks (completeness, correctness), add precision and accuracy information (quality flags)
  • 49. QC of metadata•  Metadata"should"contain:" –  Title"(dataset"name,"comprehensive,"not"just"an"acronym)" –  CitaGon"(journal"style,"include"Gtle"of"dataset)" –  General"descripGon"(abstract)" –  Contact"informaGon"(name"–"insGtute"–"email)" –  User"restricGons"(most%cases:% freely%available%if%cited )" –  Sampling"design"(collaborate"with"GE]BICH"and"ODSBP)"•  Metadata"can"also"contain:" –  Keywords,"habitat,"species"funcGonal"groups" –  Taxonomic"–"temporal"–"geographic"scope/boundaries" –  Links"(online%data,%metadata,%project%page,%DiGIR,%IPT%…)" –  Associated"documentaGon"(e.g.,%reports,%publica@ons%…)"

Geographic QC•  Related to depth: –  Is the minimum depth < maximum depth? –  Is the observation depth possible if compared with a depth map (include margin)? –  Is the observation depth possible if compared with the given depth range of the species•  Related to environmental parameters: –  Is the observation possible if compared with the given (min- max) salinity, temperature, oxygen, nutrient range of the species
  • 63. QC Presence, abundance, biomass•  Is the field sample size completed if the value of the field Observed individual count’ or observed weight >0?
  • 64. Date QC•  Fields in OBIS 1.  YearCollected 2.  MonthCollected 3.  DayCollected 4.  StartYearCollected 5.  StartMonthCollected 6.  StartDayCollected 7.  EndYearCollected 8.  EndMonthCollected 9.  EndDayCollected 10.  StartTimeOfDay 11.  EndTimeOfDay 12.  TimeOfDay 13.  Timezone
  • 65. Date QC•  Is the collection date (year, month, day, end-start) completed and valid (i.e. between 1300 and now)?•  Is the ‘collection date’ <= the ‘date identified’ and <= the ‘last modified date’•  If the start date and the end date are completed, is the start date < the end date (taking into consideration the given time)?•  Is the time/starttime/endtime >= 0 and <24 and is the timezone completed
  • 66. Date QC=>produce time graph for visual check.
  • 67. Future plans•  Expand on data types (marine extension of Darwin Core) –  Tracking data –  Acoustics –  Images (e.g. fin patterns)•  Expand geographical coverage•  Capacity building –  Biological data management –  Regional marine biological observatories•  Close collaboration with IODE projects and IOC and UNESCO programmes
