If you want to know more, listen to Dr Bernadette Sloyan talking to ABC Drive Presenter, Vicki Kerrigan:

A few weeks ago we opened up Southern Surveyor, the current Marine National Facility vessel, for free public tours in Darwin. We also invited the team from 105.7 ABC Darwin to do an outside broadcast from the bridge.

The ABC has kindly given us permission to post this audio. More information on the outside broadcast can be found here http://www.abc.net.au/local/photos/2012/10/12/3609801.htm.
