  1. A Quality control system for Biological Oceanographic data in the Northern Indian Ocean J. S. Sarupria and P.M.A. bhattadiri Indian Oceanographic Data Centre National Institute of Oceanography, Dona Paula, Goa, India.

  2. National Users Meta Data NMDC (Ocean.) IOC / IODE IOCINDIO Non classified Classified RNODC - INDO Other OCEAN databases International Users Data Flow Structure

  3. Biological Databases for Indian Ocean at IODC • Primary Productivity • Chlorophyll a • Zooplankton Biomass and Species • Zoo-benthos Biomass and Density • Microbiological Parameters (Bacterial Analysis)

  4. Major Sources of Biological Data Set • International Indian Ocean Expedition (1960-65) • National Oceanographic Programmes (1973 – cont.) • INS Darshak Cruises (1973 –78) • RV Gaveshini Cruises (1976 –93) • FORV Sagar Sampada Cruises (1985 –cont.) • ORV Sagar Kanya Cruises (1983 –cont.)

  5. QCS for Biological Parameters • Primary Productivity (PP) • Chlorophyll a (chl ) PP measured by 14C uptake rate in PP by • G – M Counter • Gas Flow Counters • Liquid Scintillation System (LSS) Chl measured by • Spectrophotometer • Fluorometer

  6. QCS Checks • M - Meta Data Information • V - Visual Inspection • R - Maximum value of specific Production • T - Tailend Increase • S - Statistical Check

  7. M – Metadata Information • Inventory level information, • Validate date, time, latitude, longitude, sounding (depth), • Duplicates, etc.

  8. V – Visual Inspection Chlorophyll (chl ) Primary Productivity (PP)

  9. T – Tailend Increase

  10. S – Statistical check • Mean +5 SD ( Coastal and Observed Depth < 50 m) • Mean +3 SD ( All Others)

  11. R – Maximum Value of Specific Production

  12. Thank You
