Description
The NUREIEV1 cruise targets the main objective of testing the hypothesis that sea storms are the main trigger for the transfer of matter and energy, including pollutants and litter, from the coastal to the deep ocean in the SE of Spain (36o20’N to 37o36’N and 2o40’W to 0o40’W). A dedicated strategy was performed during the NUREIEV1 cruise to achieve the objective including: 1) the collection of sediment cores (multicores and gravity cores) in the vicinity of the mine tailings deposit near the Portman Bay 2) the deployment of mooring lines with automated sediment traps and currentmeters to monitor particle fluxes (including pollutants released from the mine tailings deposit) and near bottom oceanographic parameters (current speed and directions, temperature, transmissivity), 3) the profiling of the water column (either from the ship by means of a CTD and from a little boat in the shallower stations) to study physico-chemical characteristics of the water column including dissolved trace elements and radiosotopes 4) the collection of floating debris including microplastics from surface waters 5) and the high resolution swath mapping and TOPA profiling to investigate seafloor features.
