| Abstract | To conduct high precision U isotope measurements of the evolving Mediterranean Sea water this scientific cruise has the major objective to collect seawater along the transit through the Mediterranean Sea, which can subsequently be studied for its U isotopic composition as well as other geochemical trace isotopes fingerprinting water masses. A second goal of the research cruise is to provide measures of the suns attenuation through marine aerosols. As part of the global MAN (Marine Aerosol Network) it is intended to collect spectral data of aerosols informing on their abundance and type along the 3000 nautical miles transect through the Mediterranean Sea, which can be used to validate remote sensing data from satellites. Though multibeam has been recorded during the cruise, it was not a major focus and the responsible party provided no acquisition information. |
