Expanding the Archaeologist’s toolkit
Once upon a time, the archaeologist’s toolkit was likely to consist of a shovel, trowel, bucket, brush, stakes and string. Today it includes a multitude of technological tools such as magnetometers, drones, ground-penetrating radar, 3D imaging and all sorts of acronyms including DGPS, LIDAR, ROVs, AUVs and many more. In the past, archaeologists were digging trenches in the ground or diving in shallow waters. These days even the roughest terrain and deepest of waters can be part of the archaeologists working environment. What was once thought impossible is increasingly possible – for example, the search for Australia’s first submarine AE1, lost in 1914 and thought one of the greatest unsolved Australian maritime mysteries, is now complete.
Today, an archaeologist can ‘look’ below the ground without even digging, they can send remote operating vehicles to incredible depths under water, and some are even investigating the potential for an ‘archaeology of the air’. And now with DNA analysis archaeologists can construct very human pictures from old bones.

Australia’s greatest naval mystery is solved at last
It is more than a century since Australia’s first submarine, HMAS AE1, disappeared without trace in the waters off Papua New Guinea. Its fate remained a mystery until late last year, when the most recent of many searches finally found its wreck.
