Work progress and main achievements
The PREPARED data set was acquired during the Eurofleets-2 cruise conducted on board the Norwegian RV G.O. Sars for the period of June 5-15, 2014. The newly acquired dataset includes about 2780 km of underway measurements (hull-mounted Acoustic Doppler Current Profiler and thermosalinograph); 60 Conducivity-Temperature-Depth (CTD) casts along 5 main transects; 22 sites for water sampling at different depths for biogeochemical characterization of water masses; 13 meso-zooplankton samplings carried out by vertical hauls (WP2 net) and 20 by horizontal hauls (Manta net) for the study of the present biological productivity of the area; about 120 km of site survey including high- resolution multibeam lines and sub-bottom profiles for the identification of surface and shallow current-related structures; 5 Box cores; and 2 Calypso piston cores 19.67 and 17.37 m long with an excellent sediment recovery up to 92%. In addition, 3 moorings were deployed for seasonal measurements of water currents direction and velocity, water mass temperature and salinity, and to determine the annual amount of local sediment input. Preliminary onboard analyses outlined the presence of different water masses occupying different portions of the In the northern end of the Strofjorden Trough, box cores revealed the presence of benthic foraminiferal microfauna Preliminary micropaleontological analyses on the long Calypso cores indicate the recovery of the past 20 ka record The oceanographic, geological, and biological data collected during the cruise are presently under process.
