How Andrew Bartholomew was found: oceanography in action
On 23 October 2004, Andrew Bartholomew fell off his trimaran
while trying to repair rigging, 200km east of Moreton Island in Queensland.
His crewman called a Mayday because he could not turn the vessel around.
An initial search that afternoon failed to find Andrew but he was rescued
the following morning by helicopter, 33km SE from his splashpoint.
Andrew's rescue was widely reported in the media but the
technology used was not mentioned. Crucial to the success of the mission
was the fact that the search was guided by CSIRO estimates of the ocean
current combined with Bureau of Meteorology estimates of the wind, via
a package developed for the Australian Maritime Safety Authority by Global
Environmental Modelling Systems Pty Ltd.
Search and rescue is possibly the most compelling reason
to make operational oceanography a reality, but there are a host of other
applications. In this talk I will use this recent rescue to illustrate
the status of the BLUElink Regional Analysis, whose task it is to estimate
of the physical state of the ocean using all available observations, both
in near-real time and for the last decade. With four altimeters now flying
and Argo well underway, ocean observation has never been better. The data
are presently under-utilised, however, which is possibly why the future
of altimetry now hangs in the balance.
