Reliable information on the depth and floor structure of the Southern Ocean has so far been available for only few coastal regions of the Antarctic. An international team of scientists under the leadership of the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research, has for the first time succeeded in creating a digital map of the entire Antarctic seafloor. The International Bathymetric Chart of the Southern Ocean (IBCSO) for the first time shows the detailed topography of the seafloor for the entire area south of 60°S. An article presented to the scientific world by IBCSO has now appeared online in the scientific journal Geophysical Research Letters.
The IBCSO data grid and the corresponding Antarctic chart will soon be freely available in the internet and are intended to help scientists amongst others to better understand and predict sea currents, geological processes or the behaviour of marine life.
The new bathymetric chart of the Southern Ocean is an excellent example of what scientists can achieve if researchers from around the world work across borders. “For our IBCSO data grid, scientists from 15 countries and over 30 research institutions brought together their bathymetric data from nautical expeditions. We were ultimately able to work with a data set comprising some 4.2 billion individual values”, explains IBCSO editor Jan Erik Arndt, bathymetric expert at the Alfred Wegener Institute in Bremerhaven.
