Expertise: Physical oceanography

Biography: Dr Efthymios Tripsanas is a Marine Geologist – Sedimentologist and he comes from Delphi, Greece. He has a long research experience on Late Quaternary seafloor sedimentary processes and their linkage to geohazards assessment, climate changes, marine pollution, and reservoir architecture of clastic sedimentary systems. His research experience comes from the study of multiple, versatile marine sedimentary settings around the world, such as in the Gulf of Mexico, Labrador Sea, North Sea and Mediterranean Sea. His research approach is based on the integration of several marine geophysical methods (multi-beam bathymetry, ultra-high and high resolution seismic-reflection data, such as 3.5 kHz, boomer, sparker and airgun profilers, side-scan sonar images, 3-D seismic volumes) with well- wireline log data (Gamma-ray, neutron density and porosity, resistivity etc.) and core analysis. His greater aspiration is the conduction of integrated oceanographic studies, through the integration and inter-active collaboration of all disciplines of oceanography.,

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

Abstract:

The study of late Quaternary marine sedimentary processes is based on several geophysical techniques (multibeam bathymetry, side-scan sonar images, high to ultra-high-resolution 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.
