  1. MetService NZ Marine Programme Julie Fletcher Manager Marine Observations

  2. MetService Marine Network NZ Marine Network at 1 March 2007 • 50 VOS Ships (39 Selected 4 Supplementary 7 Auxiliary) • 8 Drifting Buoys

  3. Marine Programme Objectives • To maintain a VOS fleet of about 40 Sel Ships & a network of 7 Drifting Buoys to provide quality real-time marine data for NZ Forecasting Operations • To exchange SHIP and BUOY data internationally to provide input to Global Models and for Climatological and Research applications

  4. MetService NZ Marine Forecasting Area (METAREA XIV)

  5. VOS Management • All PMO duties • Recruitment & Decommissioning of VOS • Reporting as SOT,VOS & VOSClim FP • Maintenance of VOS database • Monitoring, QC & follow up action • Assistance to foreign VOS

  6. NZ Ports

  7. NZ VOS Fleet Changes in 2006 • Recruited 2006 = 4 3 Container ships, 1 Gas tanker • Decommissioned 2006 = 5 Due to ship sold, end of charter • Since Feb 2004 there has been a steady increase in use of TurboWin - installed on ships’ PCs

  8. Increase in TurboWin use By end 2006, 22 of 37 Selected ships were using TW, most using version 3.6

  9. NZ VOS input 17,133 Obs onto GTS in 2006

  10. Instrumentation/Automation Manual Observing • Precision Aneroid Barometer • Fuess Aneroid Barometer (few ships only) • Marine Barograph • Stevenson Screen + thermometers • Sea Bucket

  11. Instrumentation/Automation Automation One Marine AWS - RV TANGAROA Based on Sutron 9000RTU with manual input option MTSAT comms Hourly observations Tangaroa L 70m, B13.8m, Gross tonnage 2282 Two ‘low cost’ Ship AWS planned for 2007

  12. Low Cost Ship AWS • mSTAR Ship AWS based on MetService generic family of land AWS • GPRS cellular network comms, 1 min data • Using GPS for position & True WSD • Trial on coastal ship SOC, L108m B16m Gross tonnage 5269 • If comms successful, will install on more coastal ships

  13. Communications • Most NZ VOS send via SAT C to Perth LES Early in 2007 change to LES and (SAC) numbers: 212 (POR) or 312 (IOR) SAC 1241 • A few ships email Obs to MetService • A few coastal ships phone/fax to 0800 number

  14. Obs Quality & Quantity Monitored • Count of Obs recvd in Real-Time versus Obs done in e/logbook • Forecaster & data entry staff feedback • Use of MeteoFrance VOS QC tools • Use of UKMO Monthly stats and TOR • Regular feedback to ships on quality issues

  15. TOR NZ VOS January 2007

  16. TOR NZ VOS February 2007

  17. TOR NZ VOS March 2007

  18. Inspection Regime • All NZ VOS inspected at least once per year • Some ships receive several visits • All barometers calibrated against PMO’s Vaisala PTB220AD Transfer Standard barometer which is traceable to National/International standards • Foreign VOS ships visited when possible and on request

  19. New Initiatives MCSS • MetService submitted VOS IMMT data to the GCCs in Dec 2006- first submission for many years • The IMMT files were collated from VOS using TurboWin since 2004 VOSClim • MetService plans to begin recruiting ships to VOSClim during 2007

  20. Challenges & Difficulties • Volatility – Maersk Line changes in 06/07 have affected the NZ VOS • ISPS code needs forward planning • Ship Security & the potential impact on VOF from release of Ship details on web • Looking at options to collate new Pub47 metadata • Language problems - clear instructions • Not all ships have PCs for TurboWin • Impact of short port stays

  21. Excellent International Co-operation • I work in isolation ‘down under’ • I find the marine work challenging and interesting • Thanks to global PMOs and VOS FP for help and advice • International Co-operation is excellent. • Response is always positive, timely, helpful & encouraging
