Presentation Transcript

  1. Biological indicators across heterogenous datasets Abigail McQuatters-Gollop

  2. Outline • Ecological indicator use and selection • Indicators in the context of the MSFD • Examples of applied ecological indicators

  3. The Continuous Plankton Recorder (CPR) • Plankton ecologically important • Unchanged methodology (80 years) • Longest, most spatially extensive oceanic monitoring program in the world • ~ 1 million samples • 500 plankton taxa + indicator of phyto biomass • Microplastics • Water sampler

  4. An indicator approach Edwards, M. et al (2010) TREE

  5. Determining indicators • Policy relevance • Spatio-temporal representivity • Data

  8. Indicators in MSFD • Used to monitor towards environmental targets/GEnS • Descriptors -> criteria -> indicator(s) • One criterion – multiple indicators • One indicator – multiple measures MSFD Descriptor Eutrophication Criteria for GEnS Criteria for GEnS Criteria for GEnS Water transparency Chlorophyllconcentration Algal spp. shift Indicator Indicator Indicator Secchi depth Phytop. Colour Index Diatom: dino

  9. One criterion – multiple indicators Eutrophication Algal spp. shift HABs Diatom: dino

  10. One indicator – multiple measures Eutrophication Chlorophyllconcentration Chl indicators Phytoplankton Colour Index North Atlantic

  11. Representivity: An issue of scale Edwards, M. et al (2010) TREE

  12. Representivity: An issue of scale • Spatial: Many time-series are localized • Temporal: Many time-series are short Edwards, M. et al (2010) TREE

  13. Data Policy issue • MSFD flexible -> heterogenous datasets (measures) for indicators • Broadly applicable approach • Best use of available data Indicator Dataset 1 Dataset 2

  14. Indicators from heterogenous datasets ICES CPR 1902 - 1912 1948 - present • many methods of sample collection • varying depths • inconsistent taxonomic resolution • inconsistent measures (#, p/a, rr) • patchy seasonal coverage • consistent methodology • consistent tow depth • consistent taxonomic resolution • consistent measures • monthly tow frequency

  15. CPR No. samples ICES CPR ICES 13,000 ~1M Total in DB Comparable study areas 97,093 9,191 Comparable depths 2,619 Comparable seasonality 32,454

  16. Taxonomic challenges • Differences in measures • Differences in taxonomic detail ICES CPR No. taxa 1824 ~500 No. species 1395 ~300 2 Chaetoceros 51 Not spp. Foraminfera 87

  17. Taxonomic challenges • Species name changes/ synonyms

  18. Taxonomic challenges • Taxonomic identification

  19. HABs

  20. HABs - Noctiluca ICES 1900s CPR 1980s CPR 1990s CPR 2000s

  21. Climate change – C. hyperboreous ICES 1900s CPR 1960s CPR 1970s CPR 1990s CPR 1980s CPR 2000s

  22. Ocean acidification McQ-G, Edwards, Beaugrand SAHFOS

  23. Eutrophication A. McQuatters-Gollop, M. Edwards

  24. SeaWiFS+CPR = new dataset! SeaWiFS – Chl-a CPR - PCI McQuatters-Gollop L&O

  25. Biogeographical shifts G. Beaugrand

  26. Diversity (simple) Number of dinoflagellate species per sample

  27. Biodiversity (Complex) G. Beaugrand & M. Edwards PNAS (bottom) & GCB (top)

  28. May Taxa not in CPR DB Community changes Taxa not in ICES DB

  29. Non-natives

  30. Consider.... • Policy relevance • Appropriateness of scale • Synchronize heterogenous datasets • Validation / verification
