Development of the SVP-B Drifter: More Data, Less Cost

This presentation discusses the development of the SVP-B drifter, a buoy designed to collect data at a lower cost while maintaining reliability. The drifter utilizes a flexible self-controlled network of drifters with sensor data analysis capabilities. The goal is to provide more data for different applications by selecting the necessary technical status of the buoys based on the variability of parameters under control.

  3. 1999 – 2004Technological stage of development Lifetime  2 years ID27136 / WMO33514 South Atlantic December 2002 – October 2004 Buoy’s trajectory Air pressure

  4. 2003”Smart” Buoy Project 2002 A System of Complementary Networks

  5. 2003”Smart” Buoy Project 2002 Future drifter monitoring for different areas of applicationsmight be provided with flexible self-controlled drifters networks with sensor data analysis by buoy’s processing possibilities and selection of necessary technical status of buoy according to velocity and amplitude variability of parameters under control

  6. 2003”Smart Buoy” Project SVPBD2 drifter (Storm Buoy)

  7. 2003 SVPBD2 Storm Buoy Goal of 2003 experiment in the Tropical Atlantic Investigation of the ways of tropical waves transformation in AP depression and so on Hurricane FABIAN Jul 2003- -Sep 2004 29 Aug-1 Sep 2003

  8. Developments of the “Smart Buoy” idea in 2004 New Electronics of the “Smart Buoy” PTT МТ-105А CLS Type approval -2004 Programming of Argos-2 channels (S1-S14) Size: 100  80  20 mm Weight: 90 г Sensor board ММ400 AP and up to 300 temperature sensors distributed within 600 м Size: 80  50  20 mm Weight: 65 г

  9. Developments of the “Smart Buoy” idea in 2004 SVPBD2T (temperature) drifter Two complete buoys within a shipping crate Sensor of subsurface temperature at the end of tether line

  10. Developments of the “Smart Buoy” idea in 2004 SVPBD2T (temperature) drifter Goal of 2004 experiment in the Tropical Atlantic Investigation of SST and SBT variety before, during and under the tropical storms Hurricane Frances August 2004

  11. Developments of the “Smart Buoy” idea in 2004 SVPBD2TC (chain) drifter Sensor of subsurface temperature at the end of tether line 9 temperature sensors of chain 17, 22, 27, 32, 37, 42, 47, 52, 57 m Sensor of subsurface temperature at the end of tether line

  12. Developments of the “Smart Buoy” idea in 2004 SVPBD2TC (chain) drifter Goal of 2004 experiment in the Black Sea Testing of new drifter and validation of remote sensing data. Novelties: 1. Quasilagrangian drifter 2. Stabilization of a depth of chain’s upper point

  13. Thermocline variability after data processing Cooling of upper water from 7 to 13 September

  14. Developments of the “Smart Buoy” idea in future SVPBD2L (light) drifter • Goal: Effectiveness of drifter observations • Decrease of size and price of buoy • Decrease of attendant costs (shipment, storage, etc.) • Additional measuring possibilities • Ways: • New electronics • Surface float with Ø25-30 cm • Holey Sock with Ø60-65 cm and 5-6 m length • Additional sensors and indirect measurements Parameters

  15. Conclusion 1. It seems the technological stage of drifter technology to have reliable standard data is closely to be completed 2. Future activity of drifter community might be directed to have more data with less cost of measurements 3. One of the possible ways for realization of this goal could be the development of SVPB drifter having less sizes and additional low-cost set of sensors with direct and indirect application of their data
