How come the search was in the right place?
• At the time of the rescue, it was thought – Mr Bartholomew was in the water in a life jacket– The current was to the SE
![Page 13: How Andrew Bartholomew was found: oceanography in action. A status report on the BlueLink Regional Analysis David Griffin](https://reader038.vdocuments.us/reader038/viewer/2022103022/56649cb85503460f9497eb21/html5/thumbnails/13.jpg)

How come the search was in the right place?
• At the time of the rescue, it was thought – Mr Bartholomew was in the water in a life jacket– The current was to the SE
• Subsequently, we learnt that– he was in a liferaft, ie more subject to the NW winds– The current was near zero
![Page 14: How Andrew Bartholomew was found: oceanography in action. A status report on the BlueLink Regional Analysis David Griffin](https://reader038.vdocuments.us/reader038/viewer/2022103022/56649cb85503460f9497eb21/html5/thumbnails/14.jpg)

• At the time of the rescue, it was thought – Mr Bartholomew was in the water in a life jacket– The current was to the SE
• Subsequently, we learnt that– he was in a liferaft, ie more subject to the NW winds– The current was near zero
• So it appears we got it right for the wrong reasons

Lesson (no surprise, really)
• The lag, presently about 4 days, between the latest altimetric sea level map and real-time, is a problem.

10 Dec 2004
Lesson (no surprise, really)
• The lag, presently about 4 days, between the latest altimetric sea level map and real-time, is a problem.
• In this case, the overnight change in the altimetric velocity estimate equalled the rms variability at that point.

solutions
• Reduce the latency of the analysed map– Needs more altimeters– in fact the number is likely to reduce for the foreseeable
future

solutions
• Reduce the latency of the analysed map– Needs more altimeters– in fact the number is likely to reduce for the foreseeable
future
• Use other types of ocean data– SST observations can be made synoptically– Cloudy skies prevailed, on this occasion– For the continental margins, CODAR is emerging as the
most promising technology

Let me backup….
• 2003-2004 was the golden age of altimetry, with four altimeters flying.

• 2003-2004 was the golden age of altimetry, with four altimeters flying.
• Unless the wide-swath is embarked on Jason-2 in 2008, this data density will not be reached again for many years.

Conclusions
• With 4 altimeters and many radiometers flying, and Argo well underway, ocean observation has never been better.

Conclusions
• With 4 altimeters and many radiometers flying, and Argo well underway, ocean observation has never been better.
• But, as demonstrated recently, its not yet safe to fall over the side.

• But, as demonstrated recently, its not yet safe to fall over the side.
• BlueLink, along with other GODAE projects, aims to show that operational oceanography is feasible, and worthwhile

• The Regional Analysis is an early product of Bluelink that – Gives potential users a taste of what’s to come– Provides a benchmark for the model to beat

Final word
• “Use it or lose it”
• Stakeholders, internationally, have not kept up with the rapid advances in ocean observation and modelling.
• By being relatively advanced in uptake, Australia can play an important role in ensuring that oceanography survives the risky transition from the research to operational environments
