L. Stathoplos & T. O’Brien 1998 1996 - 1998 World Ocean Database Plankton (1998)
WOD98 Plankton • Followed the 1996 Metadata Guidelines
WOD98 Plankton • Followed the 1996 Metadata Guidelines • RAW Plankton Observation Data • No QC (except for ITIS verification) • No Common Units • No Grouping or Supplemental Indexing
WOD98 Plankton • Followed the 1996 Metadata Guidelines • RAW Plankton Observation Data • No QC (except for ITIS verification) • No Common Units • No Grouping or Supplemental Indexing • Horrible Data Access
T. O’Brien et al., 2002 1999 - 2001 World Ocean Database Plankton (2001)
Problem: “No Common Units”Solution: The CBV • Common Base-unit Value • calculated from sampling metadata
Problem: “No Common Units”Solution: The CBV • Common Base-unit Value • calculated from sampling metadata • Based on Plankton Type • #/m3for zooplankton • #/mlfor phytoplankton • #/ulfor bacterioplankton
Problem: “No Common Units”Solution: The CBV • Common Base-unit Value • calculated from sampling metadata • Based on Plankton Type • #/m3for zooplankton • #/mlfor phytoplankton • #/ulfor bacterioplankton • Stored in addition to original value
Problem: ”No grouping or Indexing”Solution: The BGC • BiologicalGroupingCode • groups all taxa into major taxonomic groupings
Problem: ”No grouping or Indexing”Solution: The BGC • BiologicalGroupingCode • groups all taxa into major taxonomic groupings • “phytoplankton” • “zooplankton” • “crustacea” • “copepods” • “calanoid copepods”
Problem: ”No grouping or Indexing”Solution: The BGC • BiologicalGroupingCode • groups all taxa into major taxonomic groupings • “phytoplankton” • “zooplankton” • “crustacea” • “copepods” • “calanoid copepods” • Stored in addition to the ITIS TSN
QUALITY CONTROL • Can now use BGC and CBV to do loose “Group-based range checking”:
QUALITY CONTROL • Can now use BGC and CBV to do loose “Group-based range checking”: • Is it a reasonable “zooplankton” count • Is it a reasonable “copepod” count
QUALITY CONTROL • Can now use BGC and CBV to do loose “Group-based range checking”: • Is it a reasonable “zooplankton” count • Is it a reasonable “copepod” count • Very loose.Not considering mesh/depth/time
… then I tried to use it …(creating the WOA01 plankton fields)
Using the Data - The Best QC? Found Processing Errors • Key-entry errors • Loading / translation errors
Using the Data - The Best QC? Found Processing Errors • Key-entry errors • Loading / translation errors Found Database Issues • Corrupted data • Disappearing data
Using the Data - The Best QC? Found Processing Errors • Key-entry errors • Loading / translation errors Found Database Issues • Corrupted data • Disappearing data Found Insufficient Coverage
All “Plankton” Data WODP “plankton” data
Qualified Biomass Data WOA01 zooplankton biomass
Qualified Biomass Data • Towing Depth ( 0 – 200 m ) • Net mesh size ( ~ 300 um ) • Comparable Values ( CBV ) • ( Day vs. Night )
What about Composition & Abundance Data? A whole other talk … • Taxonomic Resolution • Life Stages • “Totals” and “Sub-totals” • “Zero Values”
What about Composition & Abundance Data? A whole other talk … • Taxonomic Resolution • Life Stages • “Totals” and “Sub-totals” • “Zero Values” Data Translation & Layout are KEY.
