Conference Proceeding

Analytical methods of Geological Oceanography and their contribution to disciplines of Biological, Chemical and Physical Oceanography

Dr. Efthymios Tripsanas,
The study of late Quaternary marine sedimentary processes is based on several geophysical techniques (multibeam bathymetry, side-scan sonar images, high to ultra-highresolution seismic-reflection data such as boomer, sparker and airgun profilers, and 3D seismic volumes) and seabed sampling techniques (box and piston cores, boreholes and drilling wells). The identification of modern and past seafloor sedimentary processes acting in any given oceanographic setting is critical for human society, since they bear a lot of information about: 1) dramatic climatic changes captured in the geological record, 2) extreme geohazards (submarine landslides, volcanic eruptions etc.), 3) source-to-sink sediment deliver, and 4) impact of ocean currents in seafloor bathymetry and sediment distribution. All of the above information is of great significance to the dispersal of pollutants, changes in the ecosystem through climatic and oceanographic changes, and the prediction of catastrophic events. The heavily populated area of the Aegean Sea is of great significance, since it is in the focus of extensive fisheries and touristic activities. In addition, dense-water production in this area and the Adriatic Sea is responsible for the rejuvenation of the bottom-water masses of the Eastern Mediterranean Sea, and thus, in the preservation of all seafloor bio-communities. Any changes in the oceanographic regime of this area or careless human activities could have a tremendous impact in the sensitive balance of the ecosystem.An example of such an integrated study from the south Aegean Sea is presented in this work, showing in a regional scale how the information hidden in the geological records might contribute to other disciplines of oceanography and in extension aid in the prediction, and thus in the potential prevention, of potential future changes in the marine environment.
