Transcript: Interview with geophysicist in the search for MH370
Hi, I'm Kristian Lynch and I'm the geophysicist on board Fugro Discovery. My primary role as geophysicist is to check and QC the geophysical data that we get off the towfish, primarily the side scan sonar data which we use to map the seabed. My role, my job really is to process the side scan sonar data from its raw format, from the towfish, into something usable that we can put into the interpretation package. And then once it's there I check it, I QC it, make sure the data's fit for purpose, make sure we're getting the right range and coverage that we need and once all that's been completed, I package the data and send it to the office at Perth. On board the vessel we process the data at 24 hour periods, so we get 24 hours' worth of data, we process it, check it, QC it, upload that 24 hours' worth of data to our office and that is where they formally interpret the side scan sonar data and report anything to the ATSB that we've found. And so they get a data upload every 24 hours of the side scan sonar data.
On board Fugro Discovery, the towfish we're using acquires side scan sonar data over a much greater range than we're normally used to, normally a few hundred metres on a standard site survey and we're acquiring side scan sonar data over a kilometre in range, which has provided a lot of unique challenges to this trip. And processing the data, getting the software to accept data over such a large range and making sure that data quality is up to scratch for a much greater range has been tough, but you know, we're acquiring good quality data now and uploading it daily and hopefully the office will, the interpretation will find the aeroplane.
