Presentation Transcript

  1. Quality Assurance / Quality Control of Real-Time Oceanographic DataandOcean Best Practices System Status Update and Plans Mark Bushnell National Coordinator, US IOOS/QARTOD • DMAC Workshop, Silver Spring, MD • May 2, 2019

  2. Board of Advisors • Kathy Bailey / U.S. IOOS (Project Manager) • Julie Bosch / NCEI • Eugene Burger / PMEL • Jennifer Dorton / SECOORA • Bob Heitsenrether / CO-OPS • Jeff King / US ACE • Shannon McArthur / NDBC • Mario Tamburri UM / ACT • Julie Thomas / Scripps (BOA Chair) • Christoph Waldmann / U of Bre­men - MARUM

  3. Manual Status Twelve Completed Manuals Dissolved Oxygen, Surface waves, In-situ Currents, Temperature & Salinity, Sea level, Wind speed and direction, Dissolved nutrients, HF Radar, Ocean optics, Passive acoustics, Phytoplankton, Streamflow Related Documents QARTOD Plan update (2017-2021) Quality Control Flags Glider Temperature & Salinity QC Implementation

  4. What’s QARTOD Doing Now? • FY 2019 QARTOD • One new manual, pH, ASLO kick-off  • Update waves & currents manuals • Shift a bit toward QA, measurement uncertainty examples (Quality Assurance of Oceanographic Observations: Standards and Guidance Adopted by an International Partnership) • Continued international interaction (e.g. OBPS) • Support for implementation

  5. pH Manual • White paper • WQ and OA • 75 SME notified • ASLO workshop • Draft by 4/2/19 • Final by 8/2/19 • NOS milestone

  6. Temperature Measurement Uncertainty • Contributions • Indicated value • Measurement error estimated by calibration • Stability of the measurement • Long-term sensor stability • Self-heating • Sensor installation • Repeatability • Reproducibility • Uncertainty Propagation

  7. Temperature Measurement Uncertainty Uncertainty Propagation – T, S, Z  Sound speed

  8. What’s next for QARTOD? • FY 2020 QARTOD Plans (tentative) • No additional manuals planned • Simplified manual updates • Continue consideration of QA, measurement uncertainty examples • Continued international interaction (e.g. OBPS) • Support for implementation

  9. Repository:https://www.oceanbestpractices.org OceanBestPractices System: a global resource to facilitate harmonization of practices for ocean observations A community best practice is a methodology that has repeatedly produced superior results relative to other methodologies with the same objective, and has been adopted and used by multiple organizations / communities. Benefits to users: • Living, sustained, comprehensive system for ocean observing practices • All formats accepted (Papers, manuals, standard operating procedures, etc.) • DOI assignment • Improved visibility from search engines, improved search capabilities • Greater Interoperability across programs and institutions • Optional peer review through Frontiers in Marine Science • Training resource
