David Mearns -
Search Director, The Finding Sydney Foundation
I was expecting another long day (and night)
today diving on the sonar targets we named as the “battle site”
between Kormoran and Sydney largely because of their location on a
line that approximates very closely the projected line of the
battle. In the end the dive was very short for the surprising
revelation that the sonar targets were actually a field of very
large rocks! When the first angular rock face came into view I
exclaimed “its geology” and almost immediately realised that this
wasn’t going to be just one isolated rock amongst a field of
Sydney’s wreckage, but that all the sonar targets were going to be
revealed as rocks instead and that our original interpretation was
wrong.
The reason it was so easy to let go of this interpretation was that
we had just spent the previous dive finding and cataloguing so much
of Sydney’’s superstructure and deck equipment in the debris field
that it was becoming increasingly hard to understand what sections
of Sydney might be found at the battle site. Also, we had been
fooled earlier during the search phase by a similar outcropping of
angular rocks that we ruled out by way of some high-resolution sonar
passes.
Before the ROV reached the seabed I said to Matthew Kelley, the
documentary film director, “be prepared for a surprise”. As
surprises go this one is actually quite pleasing for I believe it
will simplify our understanding of what happened to Sydney.
On my way to becoming a shipwreck hunter I earned degrees in marine
biology and marine geology so please forgive me for including this
picture of the rock, and friendly settlers, that fooled us. |
