Abstract

The main objectives of this cruise was to conduct measurements of physical, chemical and biological variables on a section across the Mediterranean Sea with the goal of producing a synoptic picture of the distribution of relevant properties and to compare those to historic data sets. During the cruise we were able to collect a comprehensive data set of relevant variables following the guide lines for repeat hydrography outlined by the GO-SHIP group (http://www.go-ship.org/). The measurements include salinity and temperature (CTD), the carbonate system, nutrients, oxygen, transient tracers (CFC-12, SF6), Helium isotopes and tritium, carbon isotopes, barium, Radium isotopes, Neodymium isotopes, POPs, PFOS, trace metals and Methyl Mercury. Also measurements of prokaryotic community composition, were carried out and determination of coccolithophores assembles were made. In addition nitrogen fixation experiments were carried out and aerosol sampling was conducted. The cruise sampled all major basins of the Mediterranean Sea following roughly an east-to-west section from the coast of Lebanon to through the Strait of Gibraltar and to the coast of Portugal. Also a south-to-north section from the Ionian Sea to the Adriatic Sea was carried out. We were also able to carry out sampling in the Aegean, Adriatic and Tyrrhenian Seas. The sections roughly followed lines that have been sampled previously during other programs, thus providing the opportunity for comparative investigations of the temporal development of various parameters.
