Current Targets

In our belief in openness, all of the information that we have gained is open to others to use, all of these vessels have been down for a number of years and anyone with the will and passion may search for them and congratulations to all who make the attempt. As such as information on potential targets becomes available it will be posted, often prior to the site being confirmed.

There are three main categories of targets

Wrecks that are worth looking for

All of our research is available to all with the majority posted directly on the web, the wrecks expected to be easier to find are vessels which had survivors who were able to provide reliable descriptions of the wreck location, larger vessels which will provide a bigger targets and more recent wrecks to again provide a larger target.

In no particular order these are the style of vessels we intend to search for

Targets found using the side scan that are yet to be confirmed as to what they are

Much of the data below is raw data, the position typically needs to allow for the layback of the towfish to the GPS on the boat ie the GPS is that distance ahead of the side scan unit in the direction of the Navigation Heading so the reverse bearing should be used to calculate the object position. This layback is typically a distance of 70 to 90 meters dependent on the depth of the water. Follow the link for a online conversion application

When confirming an object we drop a buoy at the point and circle the area with the sounder looking for any larger hits prior to dropping another buoy and doing a circular search.

DSTO side scan targets

Data Mining DSTO

We have utilising the raw side scan component of the 52 gigabytes of data from the Common Data Set for Shallow Survey 2003, which surveyed the area between Fort Denison and Birchgrove we have identified a number of potential targets (much of the data was collected in 1999)

We have placed all of the potential objects in a Google Earth file, which can be downloaded and is about 42 megabytes

CSIRO's RV Southern Surveyor Multi Beam Data mining greater

As part of our ongoing data review for potential wrecks we have obtained a fair amount of multi beam data from this 160 GBytes of raw data which was reviewed in two chunks of data from this we have identified several potential objects

At this stage I am not sure if any of these objects are wrecks or not

Targets that have been dived and found not to be wrecks

We have dived a number of objects and found these to be either reefs of dumped spoil from construction
