Presentation Transcript

  1. Oostende Sluice dock – Harbor project • Partners • VLIZ (=scientific PM): Hernandez F. & Cattrijsse A. • MDK (=sponsor) : Bertheloot M. • Elscolab (=installer) : Depauw P. • YSI (=installer) • Presentation by Hernandez Francisco,VLIZ

  2. Oostende Sluice dock • artificial lagoon • intended for dredging (flushing) • but never used as such • later aquaplane landing place • now : • aquaculture of oysters • sports • windsurfing • fishing • bird reserve • scientific research

  3. Sluice dock users

  4. Sluice dock bathymetry

  5. Oostende Sluice dock • mixed water intake • freshwater from Noordede river • effluent water from canal oostende-brugge • seawater from harbour • water quality problems • eutrophication • Ulva blooms • sedimentation on edges of dock

  6. Objective of the monitoring system • Based on some real-time parameters and simple evaluation • decide if the water of the sluice dock should be refreshed. • decide if the water quality in the harbour is good enough to open the sluice doors. • Data for scientific research

  7. Oostende Harbour Overview • Real-time Water Quality Buoys (x2) • Real-time level and water quality station • Salt water nutrients • MET • Water Quality Parameters • GSM communication • Powered by Solar energy • Provided as partnership between YSI and Elscolab, Belgium

  8. Installations

  9. Parameter Overview • Water Quality • Dissolved Oxygen • pH • Turbidity • Chlorophyll • Underwater PAR • Temperature • Conductivity • Salinity • Vented Level

  10. Parameter Overview • MET • Wind Speed / Direction • Relative Humidity • Air Temperature • Barometric Pressure • Solar Radiation

  11. Parameter Overview • Nutrients • Nitrate • Phosphate

  12. Systems overview • EMM2000 buoy platform • Campbell Scientific CR1000 data logger • Systea NPA nutrient analyser • YSI 6600EDS Multiparameter Sonde

  13. Data acquisition • GSM / GPRS and ADSL communication • Loggernet = Campbell scientific software • PHP scripts for database entry • SQL database • Interactive website : http://www.vliz.be/spuikom/monitoring.php

  14. Project status • Monitoring and data systems operational since 2006 • Last buoy on location since aug 2007 • Next fazes • collect data at least 4 seasons • analyse data • modelling ?? • alerting systems ??

  15. Problems encountered so far • Pressure of water very strong • Sabotage , vandalism • Cable in datalogger disconnected • Cost of communication !! • Bad coverage of telecom operator • Harbour works, no room for bouy • Reference level for water, sensor moved • Detection limits for nutrients in winter to low • Public tenders
