Cave passage under the Dachstein?
The world's most accurate survey reveals surprisingRead out
The Dachstein in the Austrian Limestone Alps has surprises: The world-famous cave system on its north side could have now yielded new surveys, possibly through a passageway with caves on the S Be connected dseite. If this is confirmed, the Dachstein caves are among the ten largest cave systems on earth.
The Dachstein S dwandh hle was discovered as early as 1886, but was considered since then as little respected and difficult to drive. However, researchers now suspect a big surprise in the interior of the widely branched cave system: scientists suspect that there is a passage for people under the Dachstein. Because only four kilometers are still missing to the large and world-famous caves on the Dachstein north side.
The cave systems of the north and south side were created at the same time about 35 million years ago and belong together geologically. If such a coherent cave system exists, it would be one of the ten largest in the world. The research project "Dachstein inside 2006" has now begun the search for such a sub-crossing and measured parts of the cave with a 3D rotation laser scanner as accurately as never before.
3D measurement with laser scanner
Professor Manfred Buchroithner, Institute for Cartography of the TU Dresden, was there with his team. "Dachstein inside 2006 is one of the largest cave expeditions in the Eastern Alps, " says the initiator, leader and coordinator of the project. The scientist has been involved in surveying the Dachstein south wall cave since the 1990s. Now he has measured with a laser scanner tens of millions more points of the cave, which put all previous measurements of quality in the shade.
Sections of the southern wall cave are now very accurately captured in three dimensions and can be displayed on the computer in 3D. The work can be the basis for further geological, hydrological and climate research. Parallel to the high-precision measurement, a team from Bad Mitterndorf under the direction of speleologist Robert Seebacher made a foray into previously unknown terrain of the southern wall cave. display
