Ocean Science and Ocean Safety

• Dr David Griffin
• CSIRO

Ocean variables and marine safety

• waves
• broaching
• currents
• navigation of passages
• trip duration, man o/b - stricken vessel drift
• wave steepening
• temperature
• hypothermia
• tropical cyclones
• sealevel
• under-keel clearance

Information thats been available for some time

• waves
• BoM predictions
• climatology
• currents
• climatology
• temperature
• satellite images
• climatology
• sealevel
• tidal and storm surge predictions

4
Whats recent

• waves
• greater accuracy
• better delivery

Whats coming

• waves
• greater accuracy
• currents
• forecasts (both tidal and non-tidal)
• temperature
• forecasts
• sea level
• forecasts

Conclusions

• CSIRO is working with BoM and RAN to implement an
  ocean forecasting system for Australia
• one of the many reasons for doing this is to
  increase safety at sea
• another is to increase the efficiency of the
  maritime industry while improving environmental
  protection
• Example min UKC at Hay Pt 300mm-gt100mm?
